Operation

6.7.2 TEST OFF LOAD

Activate by pressing the MODE

‘ ’

button repeatedly until ‘Test off Load’ is shown on the display,

then press the TICK

‘ ’

button to confirm the change. An LED indicator beside the button confirms

this action.

The Test off Load mode will only start S2 (if configured as a generator) and leave it off load.

6.7.2.1 STARTING SEQUENCE

As soon as the MODE

‘ ’

is selected and confirmed by pressing the TICK

‘ ’

button is pressed,

the output to give a start signal to an external generator controller is activated (if S2 is configured as a

generator)

If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm will appear on the display which

shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains

supply) or had achieved loading voltage and frequency (if configured as a generator).

6.7.2.2 S2 AVAILABLE

In Test off Load mode, the load is not transferred to S2 unless a ‘loading request’ is made and the S2

supply is within limits (if configured as a mains supply) or has achieved loading voltage and frequency

(if configured as a generator).

A loading request can come from a number of sources.

• S1 supply out of limits

• Activation of an auxiliary input that has been configured to remote start on load

• Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs.

As the load increases and decreases, the module may (depending upon configuration) remove non-

essential loads. This is configured as part of the Load Shedding control settings in the DSE

Configuration Suite Software.

See section entitled Load Shedding elsewhere in this document for further details.

6.7.2.3 STOPPING SEQUENCE

In Test off Load mode, S2 will continue to run on load until either:

• Pressing the START INHIBIT

‘ ’

button to return to start inhibit mode.

• Pressing the AUTO

‘ ’

button to return to automatic mode.
