The configurable Automatic Transfer Switch Model ATS 004SP allows many of the industry’s demanding specifications to be achieved.

The ATS 004SP is used to start a generator on a mains failure, sending a signal to the Automatic Engine Control Module, and transfer the load when engine’s operating criteria has been met. The time delay for a warming up the engine before accepting the load and cooling down after relieving the load is set directly on the module (via terminals T1, T2, T3, T4).

The ATS 004SP allows to work on 3 phase and single phase mains supply.

Example: to set up 140 sec. delay time, connect T1, T2, T3 terminals to the battery negative. T4 is left disconnected. Leaving all terminals T1…T4 disconnected the delay time will be 10 sec.

Under normal circumstances when mains power is available, National Grid power Supply runs through the Automatic Transfer Switch (ATS) contactors and connects to your Distribution board. When mains power fails the ATS will pause for a 20sec. period to ensure you haven’t had a power spike. ATS will then initiate Generator start signal, warming up the generator and connect the generator power supply to your home or business premises.

Upon mains power being restored the reverse happens and the controls automatically switch from the generator power back to mains shutting down the generator after a cooling down period and restoring it to standby mode.

The ATS 004SP series modules have been designed for front panel mounting.

The module is fitted into the cut-out (68X68mm) with the fixing clips removed.These are then fitted from the rear.
