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. Once the set is available and

producing an output within limits the ATS module will control the transfer devices and switch the

load from the mains to the generating set. Should the mains supply return to within limits the

module will command a return to the mains supply and shut down the generator after a suitable

cooling run. Various timing sequences are used to prevent nuisance starting and supply breaks.

Configuration is via the front panel. No other equipment such as a computer or programming lead

is required.

To initiate a start sequence in Manual Run On Load, press the

sequence is initiated.

The start/run output is activated.

Once the unit detects the alternator frequency of 45Hz, the Warm Up timer is initiated, allowing the

engine to stabilise before accepting the load.

The load will be transferred to the generator.

The module will continue to run in this mode until another mode is selected.

If the generator should fail and the mains (utility) are available, the load is transferred back to the

mains (utility).

NOTE: - If at any time the Close To Neutral Position input is activated, the switching

device that is closed will be opened. (Load shedding). The switching device will not be re-

closed until this input is removed. All other operations are unaffected.

To initiate a start sequence in Manual Run Off Load, press the

sequence is initiated.

The start/run output is activated.

The generator will be run off load and no further action is taken.

If during this time the mains (utility) should fail, the load will be transferred to the generator.

However, the unit will NOT return the load to the mains (utility). The load will stay with the

generator until another mode is selected.

NOTE: - If at any time the Close To Neutral Position input is activated, the switching

device that is closed will be opened. (Load shedding). The switching device will not be re-

closed until this input is removed. All other operations are unaffected.
