The configurable Automatic Transfer Switch Model ATS104SP allows many of the industry’s demanding specifications to be achieved.
The ATS104SP is used to start a generator on a mains failure, sending a signal to the Auto Start Enabled Generator and transfer the load when engine’s operating criteria has been met. The engine's warm-up time before accepting the load and cool-down time after relieving the load can be set directly on the module (via terminals T1, T2, T3, T4). The ATS104SP allows to work on 3 phase and single phase mains/generator supply.
How it works

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. During this time the "mains available" LED is flashing. ATS will then initiate a generator start signal (by closing terminals 3 and 4), warming up the generator within preset time set by internal programmable timer (terminals 5,6,7,8) and then connect the generator power supply to your home or business premises. Upon mains power being restored the reverse happens and the controller automatically switches from the generator power back to mains shutting down the generator after a cool-down period (cool-down period = warm-up period set by internal configurable timer) and restoring it to standby mode.

The ATS104SP series modules have been designed for front panel mounting.
The module is fitted into the cut-out (68X68mm) with the fixing clips (screw or clip type) removed.
These are then fitted from the rear.
