Controls and Indications

Part No. 057-120 8660 OPERATING MANUAL ISSUE 1 07/05/2010 ADM

6.2 STOP MODE

STOP mode is activated by pressing the button.

In STOP mode, the module will remove the generator bus from load (if necessary) before remove the start request

from the engines.

Any latched alarms (electrical trip) that have been cleared are reset when STOP mode is entered.

The engine will not be started by the DSE8660 when in STOP mode. If remote start signals are given or the mains

supply fails, the start request is not sent to the engines until AUTO mode is entered.

If Immediate mains dropout is enabled, the mains load switch is opened and closed as appropriate, when the mains

fails or becomes available to take load.

6.3 AUTOMATIC MODE

NOTE: - If a digital input configured to panel lock is active, changing module modes will not be

possible. Viewing the instruments and event logs is NOT affected by panel lock.

Activate auto mode by pressing the pushbutton. An LED indicator beside the button confirms this action.

Auto mode will allow the generator to operate fully automatically, starting and stopping as required with no user

intervention.

6.3.1 WAITING IN AUTO MODE

If a starting request is made, the starting sequence will begin.

Starting requests can be from the following sources:

• Mains supply out of limits

• High mains load (when the DSE8660 is configured for an automatic peak lopping system)

• Activation of an auxiliary input that has been configured to remote start on load, remote start in island mode

or remote start off load.

• Activation of an auxiliary input that has been configured to Aux Mains Failure.

• Activation of the inbuilt exercise scheduler.

• Instruction from external remote telemetry devices using the RS232 or RS485 interface.

6.3.2 STARTING SEQUENCE

To allow for ‘false’ start requests such as mains brownouts, the start delay timer begins. There are individual start

delay timers for each of the different start request types.

Should all start requests be removed during the start delay timer, the unit will return to a stand-by state.

If a start request is still present at the end of the start delay timer, the starting request is sent to the engine(s) over

the MSC data link.
