Contactor is electrically operated switches using by electro mechanical systems. There are 2 functions of contact: main contact and auxilliary contacts. There are also have two typical contacts on the contactor: normally open (NO) and normally closed (NC).

Contactors are designed to work continuously, have capacity power and have additional accessories. This accessories can be: auxiliary contacts, on-delay timer or off-delay timer. This contactor has a variant selection of supply voltage (coil), and the coil can be replaced in accordance with the needs of the desired coil voltage.

So it is possible to replace the coil components when damaged, or when the coil does not match the voltage used. Generally contactors are used for applications: motors, heater, lighting and the electrical distribution.

This document explains how to perform the Cold Start and Brain Dead procedures.

Product Line:
Smart-UPS

Environment:
All models, all serial numbers

Cause:
The Cold start procedure is used to determine if a UPS is functional if it will not turn on when plugged into utility power.
The Brain Dead procedure performs a hard reset of the Smart-Ups microprocessor. It does not however reset saved preferences.

Resolution:

Cold Start:
This is a great way to establish if a UPS will not turn on due to bad input power. Never use a Cold Start to troubleshoot a bad battery LED as it will clear the light most every time even if the battery is actually bad. This is because the self-test is comparing the battery health compared to the load attached. If there is no load attached, the battery will appear healthy.
 
1) Turn off and unplug the Smart-UPS from wall. Remove any attached load.
2) Press and hold the power button (labeled ""I/TEST"" on legacy non-LCD screen units) on the front of the UPS until you hear a LONG beep.
3) Let go DURING the long beep. If you let go after the beep ends you will need to try again.
4) UPS should go through its' normal self test and end up on battery with 4 beeps every 30 seconds. This shows that the UPS is functioning correctly and can both pass a self test and function on battery.
5) You can now plug your UPS back into the wall. If the input power is acceptable the UPS will transfer back online.

If your UPS will not cold start, it either means that the UPS has suffered an internal hardware failure or that it does not have a functional internal battery.
Please contact APC Technical support for further assistance.

The following video demonstrates how to perform a Cold Start on a SUA series Smart-UPS:




Brain Dead:
If you have an SUA or SUM unit, you can use this procedure to switch between Serial and USB communications. It forces a "reboot" of the internal microprocessor, but it will not erase any stored settings.
Useful for basic troubleshooting as it resets the logic of the UPS. 
 
For SU, SUA, SUM, or SURT Units:
1) Turn off and unplug UPS from wall
2) Press and hold the OFF button again (Alternately, you could disconnect the internal battery)
3) You may see a quick flash of the LED's and you should hear an audible ""click"" from the UPS.
4) Plug UPS back into the wall and turn UPS back on
 
For SMC, SCL, SMT, SMTL, SMX, and SRT Units:
1) Turn off and unplug UPS from wall
2) Disconnect Battery
3) You may hear an audible ""click"" from the UPS.
4) Reconnect battery, plug unit back in the wall, and turn UPS back on

Issue:
What are the different sensitivity settings of a Smart-UPS?
  
Product Line:
Smart-UPS

Environment:
All models except SURT, SURTA, SURTD, SRT, SRTL, SRYL, All Serial Numbers

Cause:
Normal Operation

Resolution:

The Smart-UPS detects line voltage distortions such as spikes, notches, dips, and swells, as well as distortions caused by operation with inexpensive fuel-powered generators. By default, the UPS reacts to distortions by transferring to on-battery operation to protect the equipment that you are plugging into the UPS. Where power quality is poor, the UPS may frequently transfer to on-battery operation. Battery longevity and service life of the UPS may be conserved by reducing the sensitivity of the UPS, as long as your equipment can operate normally under the conditions detailed below. The sensitivity circuit monitors Total Harmonic Distortion(THD), Change in Voltage over Time(dv/dt), and Frequency (Hz) out of tolerance.


NOTE:

\n

The sensitivity circuit looks at these three parameters (THD, dv/dt, Hz) and makes a quantitative analysis based on all three things using a proprietary algorithm.

\n

There are not pre-defined limits for each parameter. (IE: There is no way to say "At medium sensitivity, the UPS will transfer at X percent THD.") 

Smart-UPS products default to "High" sensitivity. Lowering the sensitivity may allow your UPS to operate online during a wider array of input conditions, however it also increases the transfer time of the UPS. "Transfer Time" is the length of time a Line-Interactive UPS takes to switch from online to on-battery operation. The level of power disturbance can affect transfer time when the unit is set to Medium or Low. Some sensitive loads may not be compatible with the extended transfer times experienced at lower sensitivity settings. If you experience a load drop during online to on battery transfer when the UPS is set to medium or low sensitivity you may need to increase the sensitivity setting to high. Extremely sensitive loads may perform better with an online UPS such as a Smart-UPS RT which has no transfer time.

High Sensitivity Mode
In the event of any type of voltage disturbance, the UPS will transfer to battery power and watch the AC line until it can transfer back to line. The transfer time in this mode depends on how far the line voltage deviates from the sine wave reference. It is generally 2-4 milliseconds.

Medium Sensitivity Mode
In the event of a RMS voltage-out-of-tolerance(High/Low/No) and RMS-rate-of-change disturbances(dv/dt) in the line voltage, the UPS will transfer to battery power and watch the AC line until it can transfer back to line. In this mode the transfer times are longer but still within acceptable limits to insure the continuity of a computer's operation. They are generally 6-8 milliseconds.

Low Sensitivity Mode
In the event of a RMS voltage-out-of-tolerance disturbances(High/Low/No) in the line voltage, the UPS will transfer to battery power and watch the AC line until it can transfer back to line. In this mode the transfer times are longer but still within acceptable limits to insure the continuity of a computer's operation. They are generally 8-10 milliseconds.


"SU" Smart UPS 700va or larger and "SUA" Smart-UPS 1000va or larger have a sensitivity button on the rear panel of the UPS. To change the sensitivity of the UPS, press the small, white "sensitivity" button* on the rear of the UPS. Use a pointed object (such as a pen) to do so. The default setting is "high"; press the button once to set the sensitivity to "medium", and press it again to set it to "low"; pressing it a third time will set it back to "high". The sensitivity setting change will take effect immediately. The green LED next to the button is a sensitivity setting indicator - brightly lit is "high" sensitivity, dimly lit is "medium", and off is "low" sensitivity.

Next Generation Smart-UPS (Part Numbers beginning with "SMT" or "SMX") feature a fully interactive LCD display. By default these units feature a "Local Power Quality" setting, which is a combination of Sensitivity and Transfer Voltages. To configure sensitivity separately, you must enable "Advanced Menus". This is enabled via the "Configuration" menu on the LCD screen. Once "Advanced Menus" are enabled, you will see several new options under the "Configuration" menu, including "Sensitivity". From there, you can select "Normal" (High), "Reduced" (Medium), or "Low".

Notes:

\n

• In any sensitivity mode, a Smart-UPS will transfer to battery when the Frequency(Hz) is out of tolerance(+/-5%).
• If your model Smart-UPS has neither a sensitivity button or LCD screen, you may still adjust sensitivity via the PowerChute application.
• Some equipment may be more sensitive to line disturbances. The lower your sensitivity setting, the longer the transfer time. To find out how you equipment may react, please see your equipment manufacturer.

Resolution

These steps will require local access to NMC1 and NMC2 device(s) and require you to directly connect to it with the APC serial configuration cable. Browse the steps below for your device model in order to reset the Administrator's password.

NOTE: Connecting a non-APC serial cable during the procedures below can cause unwanted erratic device behavior.

Web/SNMP Card & Network Management Card 1 Procedure 

In addition, if you are trying to reset a password on a UPS that has more than one SmartSlot accessory installed in it (i.e. AP9607 Interface Expander), it may be required to temporarily remove the other SmartSlot accessories to gain direct serial access to the NMC console interface. Please reference that accessory's User Guide on how to do that. It is also important to make sure that the accessories are installed in the correct order, referencing this document.

1.) Select a serial port at the local computer, and disable any service that uses that port.

2.) Refer to the chart below and obtain the correct communication cable for the Network Management Card 1-enabled device:
 \n

Device	Configuration Cable Part Number
Most UPS devices with a DB-9 style serial port	940-0024 or 940-1524 (DB-9 to DB-9)
Rack PDU (AP84XX*, AP86XX*, AP88XX*, AP89XX*, AP78XX, AP79XX)	940-0144 (RJ-12 to DB-9)
1st Generation Rack Automatic Transfer Switch (AP7750, AP7701, AP7722)	940-1000 (DB-9 to DB-9)
2nd Generation Rack Automatic Transfer Switch (AP77XX, excluding 1st Generation SKUs)	940-0144 (RJ-12 to DB-9)
4th Generation Rack Automatic Transfer Switch (AP44XX)	940-0144 (RJ-12 to DB-9)
NetBotz 200/Environmental Monitoring (AP9319, AP9340, AP9320)	940-0103 (DB-9 to DB-9)
Rack Air Removal Unit (ACF400, ACF402)	940-0103 (DB-9 to DB-9)

\n* Indicates the device uses NMC2 password reset procedure.

3.) Connect the serial cable to the selected port on the computer and to the configuration port at the UPS/Network Management Card Embedded device.


4.) Run a terminal program (such as HyperTerminal®) and configure the selected port as follows, depending on your device model type (refer to the user's manual if the device is not listed below):

 \n

Device	COM Port Settings
Most UPS devices with a DB-9 style serial port	2400 bps, 8 data bits, no parity, 1 stop bit, and no flow control
Rack PDU 1G and 2G**	9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control
1st Generation Rack Automatic Transfer Switch (AP7750)	19,200 bps, 8 data bits, no parity, 1 stop bit, and no flow control for initial configuration, 2400 bps for NMC configuration - refer to user's manual for more information
2nd Generation Rack Automatic Transfer Switch (AP77XX, except AP7750)	9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control

Rack Air Removal Unit (ACF400, ACF402)	9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control

\n
**Indicates the device uses NMC2 password reset procedure.

NOTE: For three phase UPS devices, it will be necessary to remove the communication cable from the port labeled "Display" that connects to the PowerView display prior to completing this reset procedure.

5.) Press ENTER, repeatedly if necessary, to display the User Name prompt. If you are unable to display the User Name prompt, verify the following:\n\n

• The serial port is not in use by another application.
• SCROLL LOCK is off/disabled.
• The terminal settings are correct as specified in step 3.
• The correct cable is being used as specified in step 2.

\n
6.) Press the Reset button once. The Status LED will flash rapidly (almost immediately) while alternating between orange and green. NOTE: If you are using an AP9606, proceed to step 7. Press the Reset button again a second time immediately while the LED is rapidly flashing - which will cause the LED to then go off - in order to reset the User Name and Password to their defaults temporarily (the default User Name and password are both apc).
 
7.) Press ENTER as many times as necessary to redisplay the User Name prompt, then use the default, apc, for the user name and password. (If you take longer than 30 seconds to log on after the User Name prompt is redisplayed, you must repeat step 5 and log on again.)
 
8.) From the Control Console menu, select System, then User Manager.
 
9.) Select Administrator, and change the User Name and Password settings, both of which are now apc. 

10.) Press CTRL+C, log off, reconnect any serial cable you disconnected, and restart any service you disabled.

NOTE: For Network Management Cards running lower than version 2.5 firmware (or models AP9606), step 6 (the second reset press) will not be necessary.

Network Management Card 2 Procedure

NOTE: On v6.X.X firmware, the Super User or Administrator level accounts can reset other Administrator, Device, Read Only, and Network Only user passwords. This procedure may not be required if the Super User password or at least one set of Administrator credentials are known.

You can use a local computer that connects to the Network Management Card through the serial port to access the command line interface. This port is labeled "Console" and is on the Network Management Card itself. You'll also need to press the pinhole reset button - access is located on the front of the Network Management Card to the right of the Ethernet jack.

1.) Select a serial port at the local computer, and disable any service that uses that port.

2.) Connect the provided serial cable (APC part number 940-0299) to the selected port on the computer and to the configuration port at the Network Management Card.

3.) Run a terminal program (such as HyperTerminal®) and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.
 
4.) Press ENTER, repeatedly if necessary, to display the User Name prompt. If you are unable to display the User Name prompt, verify the following:\n\n

• The serial port is not in use by another application.
• SCROLL LOCK is off/disabled.
• The terminal settings are correct as specified in step 3.
• The correct cable is being used as specified in step 2.

\n
5.) Press the Reset button once (please note, sometimes aligning a paper clip or similar to the pinhole reset button can be difficult. It is suggested to hold the paper clip or similar device towards the top of the reset button hole and press gently until the alignment is made). Wait 5-7 seconds (the Status LED will be off while you wait) and then after that period of time, the Status LED will flash rapidly while alternating between orange and green. Press the Reset button a second time immediately while the LED is rapidly flashing - which will cause the LED to then go off - in order to reset the User Name and Password to their defaults temporarily (the default User Name and password are both apc).

6.) Press ENTER, repeatedly if necessary, to display the User Name prompt again, then use the default, apc, for the User Name and password. (If you take longer than 30 seconds to log on after the User Name prompt is redisplayed, you must repeat step 5 and log on again.)

7a.) For v5.X.X firmware only: At the Command Line Interface, use the following commands to change the User Name and Password settings, both of which are now temporarily apc:
 
user -an yourAdministratorName
user -ap yourAdministratorPassword

For example, to change the Administrator user name to Admin, type:

user -an Admin
 
7b.) For v6.X.X firmware only: At the Command Line Interface, use the following commands to change the Password setting for the Super User account, for which the username is always apc, and the password is now temporarily apc:

user -n apc -pw yourNewSuperUserPassword
 
For example, to change the Super User's password to p@ssword, type:
 
user -n apc -pw p@ssword

Secondly, the Super User account can be disabled for security reasons. In addition to possibly needing to reset its password, you may need to re-enable the account if no other administrative access is available or known. To do that, type:
 
user -n apc -e enable
 
Because the Super User can also reset the password for any account, you can reset other user's passwords as well. For example, to change the password for user upsadmin too, type:
 
user -n upsadmin -pw p@ssword
 
NOTE: Per the v6.X.X's firmware User Guide, please note that changing user name information is no longer supported via the Command Line Interface. If a user's user name needs to be changed, it must be deleted and re-created. The Super User will also have access now to log in and adjust any other user's password.
 
8.) Type quit or exit to log off, reconnect any serial cable you disconnected, and restart any service you disabled.
 
The following video explains the password reset procedure for Network Management Card 2 with firmware revisions of v6.X.X.

https://www.youtube.com/watch?v=PSzkHWVQfAo

Network Management Card 3 / Network Management Card for Easy UPS Procedure

NOTE: Resetting your NMC will reset the card to its default configuration.

If you forget your NMC’s password, you must use the Reset button on the NMC to wipe all configuration, including the password.

1.) Hold down the Reset button for 20-25 seconds, ensuring the Status LED is pulsing green during this time.

2.) When the Status LED change to amber or orange, release the Reset button to allow the NMC to complete its reboot process.

3.) After the NMC reboots, you must re-configure your NMC. For more information, see the NMC Installation Guide on the APC website.
NOTE: It is recommended you export the config.ini file after configuring your NMC to prevent loss of data in the event of a lost password.

Issue:

UPSs are generally installed and placed in places not easily seen by a user (i.e., under a desk, in a wiring closet, etc). Therefore, in order to provide proactive warnings of changing UPS and power conditions to users, APC's UPSs have audible tones. An occasional single beep from the UPS is normal UPS operations. This means that the UPS is protecting the load. Below is a partial list of audible indicators and possible meanings. Please refer to your Back-UPS user manual for the complete list of audible tones.

Product Line: 

All Back-UPS Families

Cause:

1.) The Back-UPS product is operating on battery power - This alarm indicates that the UPS has transferred from On Line operation to On Battery operation. The Battery Power Supplied outlets are now battery-powered.

2.) The Back-UPS product has entered a low battery condition - This alarm indicates that the UPS has reached a Low Battery condition and will soon shut down. The UPS can only operate on battery for a limited amount of time. In order to protect the unit's batteries from discharging too much, the UPS will shut down and turn off its output. To warn you that the unit will soon shut down, the UPS will sound this alarm 2 minutes before the actual shutdown. With optional APC management software, 2 minutes can be changed to give you more of a warning of impending shutdown. If you hear this tone, you should immediately gracefully shut down your operating system to prevent data loss or corruption.

3.) Capacity Overload - This alarm indicates that the UPS has detected an Overload condition. If this alarm is sounded, try removing non-essential equipment. The alarm will remain until the load is reduced. To determine if your UPS is capable of handling the equipment you want to protect, visit APC's UPS Selector .

4.) Unit failed a self-test - Most Back-UPS products perform an internal self-test every 14 days, checking the integrity of the battery. If the battery fails the self-test, the "Replace Battery" LED will illuminate. The Replace Battery LED is a WARNING that the battery may be near the end of its life, and replacement is typically recommended within 2-4 weeks.

5.) Disabling UPS audible alarm tones  - When using the PowerChute Personal Edition software, the UPS audible alarm tones can be disabled. (Not available on all Back-UPS Models)


Resolution:
1.) The Back-UPS product is operating on battery power
Tones:
• 4 Beeps Every 30 Seconds (the amber On Battery LED will be illuminated)
. 1 beep every 5 seconds

- If the input voltage is determined to be unsafe for your computer equipment, the UPS will transfer to On Battery. The alarm will stop once the unit returns to On Line operation. Please refer to the technical specification section of your user manual for the acceptable voltage window. Occasional transfers to On Battery should not be a matter of concern, but rather, should be considered normal operation. The UPS is trying to provide clean, safe, and reliable power. If your unit shipped with APC management software it may be possible to change the default acceptable voltages that the unit shipped with. Please see the help section of the APC management software for instructions to do this.

- If the Frequency deviates + or - 5 % this will also cause a Back-UPS product to transfer to battery power. Frequency distortions are most commonly caused by generators that are undersized. Always make sure a generator is 3 to 5 times the size of the total load attached to ensure it can maintain a steady output frequency. There is no way to change the +/- 5% deviation.

- If the shape of the incoming power is considered "too dirty", some Back-UPS products may transfer to battery power. This is most likely the problem if you have already confirmed that the input voltage is within acceptable limits. Most Back-UPS products have the ability to change their sensitivity to the shape of the input power from high to medium or even low. Please see your user manual for details as to how to adjust this setting.

Note: If the power disturbance is brief, you may only hear the unit beep once or twice.

2.) The Back-UPS product has entered a low battery condition
• Continuous Beeping (the amber On Battery LED will be illuminated)

Note: This graceful shutdown will occur automatically if the APC management software is being used.

3.)Capacity Overload
• Constant, Solid Tone (the red Overload LED will be illuminated)

If the Back-UPS emits a constant flat tone and reducing the load does not solve the problem please try the following steps:

1) Turn the UPS off.
2) Unplug all the equipment from the UPS
3) Unplug the UPS from the wall outlet
4) Push and hold the power on button (you will hear two beeps) release the button before the second beep ends.

At this point, the UPS will either go into battery and work fine or it will continue to emit a constant flat tone. If the unit still emits this tone, it is an indicator that the UPS was permanently damaged due to the overload. In some failure conditions, the UPS may continue to emit this constant tone even when removed from utility power. To immediately silence this alarm during this condition, the internal battery must be disconnected via the UPS battery access door. Please contact APC Support for replacement options or visit APC's Replacement UPS Selector.

4.) Unit failed a self-test
• Continuous Beeps for One Minute; Repeated Every 5 Hours (Replace Battery LED will be illuminated)

Step 1:
Confirm that the Back-UPS product's internal battery has been connected. The instructions on how to do this are in the user manual.

Step 2:
Verify that the UPS is not being overloaded (refer to the Back-UPS products User Manual for the watt capacity of the battery outlets). APC recommends plugging only the computers and monitors in the battery-powered outlets, other peripherals should be plugged into the "Surge Only" outlets labeled on the back of the UPS. Outlet strips or surge protectors should NEVER be plugged into any UPS. Remove any excessive load from the UPS. On the same note if the Back-UPS product is close to being fully loaded (>80% of the battery outlet’s watt capacity) it is not recommended that the Back-UPS product be used as a master on switch to turn on your equipment. Instead, power the Back-UPS product on letting it complete its self-test before turning on the connected equipment. It is also acceptable to leave the Back-UPS product on and never turn it off.

Step 3:
Disconnect the external battery pack if one is in use. A self-test should be performed with the UPS fully charged (charging without interruption or transfer to battery for 5 hours) and normal load attached. To do this, make sure the Back-UPS product is plugged into the wall, push the On/Off button and hold it for approximately 4 seconds until a long tone is heard. The "On Battery" (yellow) LED will illuminate while the "On-Line" (green) LED will flash. This test will last about 15 seconds and will yield one of 2 results: If the Replace Battery LED stays lit (the unit will beep/chirp for 1 full minute indicating a failed test) the battery should be replaced. If the replacement battery LED turns off, then the battery does not need replacement.


Step 4: (Proceed only if "step 3" does not clear the Replace Battery LED)
The Back-UPS product comes with a 2-year warranty which includes the battery. If the Back-UPS product was purchased within 2 years, please contact APC Support and reference the steps performed in this document. Also, include the exact part number and serial number found on the bottom of the Back-UPS RS/XS.

If the Back-UPS product is outside of the factory warranty, use the UPS Replacement Battery and Upgrade Selector which will offer out-of-warranty options for replacing an exhausted battery pack or upgrading to a new APC Back-UPS.

5.) Disabling UPS audible alarm tones.

Managing UPS Audible Alarm Settings via On-Device Mute Feature (Back-UPS ES 'M' Series and Back-UPS Pro)

Using Quick Mute on APC Back-UPS ES M-Series to temporarily silence alarms:


Silencing Audible Alarms on APC Back-UPS Pro via Mute Button:


Managing UPS Audible Alarm Settings via PowerChute Personal Edition
Step 1:
Connect the UPS's RJ45 to USB communications cable between the UPS and the computer. Ensure the USB cable is inserted directly into one of the host computer's native USB ports. Do not use a hub or after-market USB cards to establish communications.

Step 2:
Once the computer has detected the "New Hardware Device", see Video: Installation instructions for PowerChute Personal Edition 3.0.2 or 3.1  onto a currently supported operating system.

Step 3:
Once the software has been properly installed, the UPS's audible alarms can be disabled by accessing the "Notifications Configuration" section found under the "Configurations" Tab and altering the "Battery Back-UPS Alarm" section. Here the alarms can be enabled for all events, disabled for all events, and disabled during specific UPS conditions or during customer-specified time periods.

Issue:

I require the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS)  for various APC single phase UPS products.


Product Line:

All APC Single phase UPS


Environment:

All APC UPS


Cause:

\n

The majority of batteries used in APC by Schneider Electric Uninterruptible Power Supply (UPS) systems and Replacement Battery Cartridges (RBCs) are contained within cartridges and are sealed, non-spillable, maintenance-free lead acid batteries. The batteries are a manufactured article consisting of a plastic, sealed case, terminals and flame arrestor vent caps. Case color varies. The electrolyte is contained within the case and consists of the electrolyte held captive in an adsorbed glass mat (AGM) or gel matrix. There is no “free” electrolyte to leak out of the case. Under normal use and handling, there is no contact with the internal components of the battery or the chemical hazards. Under normal use and handling, these products do not emit regulated or hazardous substances. The design life of a sealed lead acid battery is 3-5 years depending on environmental factors. Using the batteries past the end of it’s design life can result in electrolyte leakage.  

In a few cases, Replacement Battery Cartridges (RBCs) containing High Power Lithium Ion Cell, Phosphate-Based are also used. These batteries are used stricitly in select models found in the Back-UPS Connect family.
