705 ATS controller operators manual 1 INTRODUCTION The 705 is a configurable Automatic Transfer Switch control module, and is designed to work in conjunction with generator control modules that will accept a remote start input. It monitors the incoming AC mains supply (1 or 3 phases) for under voltage. If the voltage falls out of limits the module will issue a start command to the generating set controller.
705 ATS controller operators manual 2.3 AUTOMATIC MODE OF OPERATION This mode is activated by pressing the pushbutton. An LED indicator beside the button confirms this action. Whether the start sequence is initiated by mains (utility) failure, or by remote start input, the following sequence id followed: To allow for short term mains supply transient conditions or false remote start signals, the Mains Fail Delay timer is initiated.
705 ATS controller operators manual 3 CONFIGURATION INSTRUCTIONS ♦ With the unit in Auto mode, Configuration Mode is selected by operation of a small switch on the rear, left-hand edge of the PCB. This is partially hidden to prevent accidental operation.

705 ATS controller operators manual 6 SPECIFICATION DC Supply: 8 Volts to 35 Volts DC Continuous. Cranking Dropouts: Able to survive 0 Volts for 50 mS, providing supply was at least 10 V before dropout and supply recovers to 5 Volts. This is achieved without the need for internal batteries.
To Positive supply via fuse To Fuel Solenoid Example of relay pins connected to DSE solid state output to drive a fuel solenoid. See overleaf for overall typical wiring diagram NOTE: - The Close Mains Relay should be NORMALLY CLOSED when de-energised for fail safe reasons.
(see note) NOTES : The remote start inputs of all DSE modules can be connected directly to the start/run output (terminal 3) of the 705 ATS controller, providing that the DC supplies are common to each module. Wiring of remote start relay above is shown for connection to an engine controller requiring a battery negative signal Battery to start the set (such as DSE controllers).
