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

5.6 CONTROLS

Stop / Reset

This button places the module into its Stop/Reset mode. This will clear any alarm conditions for which

the triggering criteria have been removed. If the engine(s) is(are) running and the module is in Stop

mode, the module will automatically instruct the changeover device to unload the generator bus

(‘Close Bus becomes inactive (if used)). The start request is taken away. Should a remote start

signal be present while operating in this mode, a remote start will not occur.

Manual

This mode allows manual control of the functions. Once in Manual mode the module will respond to

the start button, sending a start request to the engine(s) over the MSC link. If the engine is running

off-load in the Manual mode and a remote start signal becomes present, the module will

automatically instruct the changeover device to place the generator bus on load (‘Close Bus becomes

active (if used)). Upon removal of the remote start signal, the generator bus remains on load until

either selection of the ‘STOP/RESET’ or ‘AUTO’ modes.

For further details, please see the more detailed description of ‘Manual operation’ elsewhere in this

manual.

Auto

This button places the module into its ‘Automatic’ mode. This mode allows the module to control the

function of the system automatically. The module will monitor the remote start input and mains supply

status and once a start request is made, the set(s) will be automatically started and placed on load.

Upon removal of the starting signal, the module will automatically transfer the load from the generator

bus and shut the set(s) down observing the stop delay timer and cooling timer as necessary. The

module will then await the next start event. For further details, please see the more detailed

description of ‘Auto operation’ elsewhere in this manual.

Test

This button places the module into its ‘Test’ mode. This allows an on load test of the generator(s).

Once in Test mode the module will respond to the start button, sending a start request to the

engine(s) over the MSC link, and run on load, in parallel with the mains supply.

For further details, please see the more detailed description of ‘Test operation’ elsewhere in this

manual.

Start

This button is only active in TEST or MANUAL mode.

Pressing this button in manual or test mode will request the engines to start and run off load (manual)

or on load (test).

Mute / Lamp Test

This button silences the audible alarm if it is sounding and illuminates all of the LEDs as a lamp test

feature.
