External Feature 17 contacts are located on the Series 300 Group G controller.  The terminals for the External Feature 17 are TB1-8 and TB1-9.  Refer to the ATS wiring diagram.

Connect a Normally Closed set of contacts across the terminals.  Opening the contact will cause the generator to start and run, and transfer to Emergency side once the ATS controller recognizes the Emergency source as an acceptable source.

Before opening the contacts, make sure to enable the Ext. Feature 17 in the ATS controller first.





Enable the External Feature 17 via the Group G controller.  Make sure there is a CHECK mark on the box corresponding to Ext Feature 17 to ENABLE it.  Refer to the Group G Controllers User Guide.

The signals provide Pre-transfer and Post-transfer time delay notification via dry set/s of form C contacts when transferring from Emergency to Normal and from Normal to Emergency. 

ASCO Transfer Switches offer standard and optional accessories for pre-and-post Transfer signals depending on the type/series of the Transfer Switch; please see the below accessory information about the Pre and Post transfer signal.

The most common application of Pre-Transfer Signal are as follows:

1. Motor Loads - used for disconnecting the equipment that allows residual load-side voltage to decay to prevent high inrush currents.  The motor load is reconnected after a user-specified delay.
2. Elevator Controls - In order to avoid stranding passengers, it is necessary to provide a means for elevators to reach a building floor to allow passenger egress. The pre-transfer signal can interact with an ATS controller to signal elevator controls that transfer is about to occur. The elevator controls then send the elevator to the nearest floor of the building and open its door before power is interrupted.

The runtime shown on the web site is an estimate and is offered as a guide only as there are a lot of factors that will determine the actual runtime achieved in anyone application, including : 

Temperature - The temperature of the battery within its environment will affect its capacity and therefore the available runtime. Capacity decreases at lower temperatures and increases at higher temperatures. 

Age of the battery - A new battery will only reach its optimum capacity after a two or three discharge and charge cycles, plus as it ages its capacity will decrease, typically down to approximately 80% at the end of its life. 

Temperature & battery life - Whilst the capacity of a battery will increase at higher temperatures its life will be reduced, typically by 50% for every 10 deg Celsius rise above 25 deg Celsius. 

Recharging the battery - Whilst a battery will recharge to 90% capacity fairly quickly, it can take up to 72 hours to reach its full capacity again. This is because as the battery approaches its fully charged state it becomes more difficult to get energy back into the battery. 

The frequency and depth of discharge cycles - The frequency and depth of discharge will affect the life and capacity of the battery, reducing with a higher number and depth of cycles. 

The load itself - In particular the actual size of the load compared with the theoretical load. 

The load characteristic - The runtime calculation is based on tests with resistive load and may differ with inductive or capacitive load. 

Light load accuracy- The estimated runtime values quoted on the web are based on an algorithm which tends to be less accurate for light loads and long runtime applications. 

Storage - When a battery is stored, be that within a UPS that is not connected or as a RBC, it will gradually lose capacity through self discharge, a situation which is accelerated at higher storage temperatures. So providing the storage period and temperature has not exceeded the typical battery manufactures specification the battery will return to near full capacity, but sufficient recharge time, 48 - 72 hours must be allowed for the capacity to be recovered. Typical maximum storage period is 12 months at 25 deg Celsius, 8 months at 30 deg Celsius and 4 months at 40 deg Celsius."},{"Title":"Global Resets - Digital Power Meter PM5100","UrlName":"FA343239","LastModifiedDate":"26/01/2025","products":"METSEPM5111, METSEPM5110, PM5000 series, METSEPM5110, METSEPM5100","score":1.010909090909091,"firstpublisheddate":"28/03/2018","answer":"

Global resets allow you to clear all data of a particular type, such as all energy values or all minimum/maximum values.
Meter Initialization is a special command that clears the meter’s recorded logged data, counters and timers. It is common practice to initialize the meter after its configuration is completed, before adding it to an energy management system.

This standard does not apply to protection against the risk of explosion or conditions such as humidity, corrosive gasses, fungi or vermin.
