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.
2 DESCRIPTION OF OPERATION
2.1 MANUAL RUN ON LOAD
To initiate a start sequence in Manual Run On Load, press the pushbutton, and the start
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.
2.2 MANUAL RUN OFF LOAD
To initiate a start sequence in Manual Run Off Load, press the pushbutton, and the start
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.

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. After this delay 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.
If the remote start is being used and has been configured to Remote start is on load, or the mains
has failed, the load will be transferred to the generator.
On the return of the mains supply, (or removal of the Remote Start signal if the set was started by
remote signal), the Mains Return delay timer is initiated. Once it has timed out, the load is
transferred back to the mains (utility). The Cooling timer is then initiated, allowing the engine a
cooling down period off load before shutting down. Once the Cooling timer expires the Start/Run
output is de-activated.
If the mains should fail (or a Remote Start signal is re-activated) whilst the generator is Cooling
down, the load will be immediately transferred to the generator.
If the generator should fail, i.e. frequency falls below 20Hz the unit will switch back to the mains,
even if the mains is not available.
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.

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.
♦Once Configuration Mode is selected, the ‘Auto’ LED will commence rapid flashing, and all
normal operation is suspended.
♦The Run On Load pushbutton can be used to select the LED ‘code’ that corresponds to
the required function. The 5 left-hand LED’s will form the code. See configuration table over
leaf.
♦The Run Off Load pushbutton will allow the user to change the associated value. The 3
right-hand LED’s inform the user of the current setting for the chosen function. See
configuration table over leaf.
♦When the required parameters are displayed, pressing the Auto button will save
the new setting, and the process is repeated for each function change.
♦When configuration is complete, the Configuration Mode Selector Switch should be returned
to the ‘Normal’ position.

Programmable input can be configured to one of the following.
♦Remote start – If the input is active the generator will be started, and stopped if the input is deactive. Mains fail is
allways active.
♦Simulated mains – If the input is active the generator will not start in the event of a mains failure. E.G. if the
generator is supporting a non 24 hour operation, a 24 hour timer can be used to prevent a mains failure from
starting the generator and taking load.

7 SOLID STATE OUTPUTS
DSE’s utilisation of Solid State Outputs gives many advantages, the main points being:
♦No Moving Parts
♦Fully Overload / Short Circuit Protected.
♦Smaller dimensions hence lighter, thinner and cheaper than conventional relays.
♦Less power required making them far more reliable.
The main difference from conventional outputs is that solid state outputs switch to negative (–ve)
when active. This type of output is normally used with an automotive or plug in relay.

NOTE: - The Close Mains Relay should be NORMALLY CLOSED when de-energised for fail
safe reasons. Should the DC supply fail the mains will always be available. The output from the
DSE solid state output when energised will OPEN the relay therefore isolating the mains supply.

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
to start the set (such as DSE controllers). Modules with different input requirements may need alternative wiring details.
If in doubt, consult the manufacturer of your engine control unit.
