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.

There are three way to selection of contactor:

1. Types of applications, there are many application characteristics (utilization categories): such as AC-1, AC-3, AC-4 and other categories.

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.

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.

1. On J1, terminate twisted pair cable. 
2. Set proper termination for S1 (Terminating resistor).
    2.1 Terminating resistor should be ON if 5210 is the last device on the loop.
    2.2 Otherwise, it should be OFF.
3. Choose 2-wire or 4-wire (S2).
    3.1. For 2-wire, connect on any + or  - terminals. Moving the DIP SW will internally connect the terminal. No need for external jumper.

For the contact-driven type, the end-user needs to supply a normally-closed set of contacts to the designated terminals; the opening of which will trigger the load shed response. For the voltage-driven type, the end-user needs to apply the rated load-shed input voltage at the designated terminals; the removal of which will trigger the load shed response. For both cases, the load shed response is to remove the loads away from the emergency source when the TS is connected to the emergency side OR prevent the transferring of loads to the emergency source when the TS is not yet connected to the emergency side.

For some applications the load shed accessory may not be needed. To disable the load shed accessory, the end-user has to permanently apply a closed circuit to the designated terminals for the contact-driven type OR maintain the application of the rated load shed input voltage to the designated terminals for the voltage-driven type. If the foregoing methods are not feasible, one other way is to remove the LDCR relay from the load-shed add-on panel.

The suggested steps are the following:\n

1. Completely de-energize the unit.
2. Open the door and locate the add-on panel for the load shed accessory. The add-on panel is usually mounted on the inner side of the door.
3. Look for the relay labelled LDCR and remove it from its base.
4. Close the door back and re-apply power to the unit.
