4.11 SCHEDULER
The controller contains an inbuilt exercise run scheduler, capable of automatically starting and
stopping the set. Up to 16 scheduled start/stop sequences can be configured in banks of 8 to either
repeat on a 7-day or 28-day cycle.
Scheduled runs may be on load or off load depending upon module configuration.

Exercise Scheduler.
In this example the set
starts at 09:00 on the first
Monday of each month and
run for 5 hours, then start
at 13:30 on every Tuesday
and run for 30 minutes.
4.11.1 STOP MODE
• Scheduled runs do not occur when the module is in Stop mode.
4.11.2 MANUAL MODE
• Scheduled runs do not occur when the module is in Manual mode.
• Activation of a Scheduled Run ‘On Load’ when the module is operating Off Load in Manual
mode has no effect, the set continues to run Off Load
4.11.3 AUTO MODE
• Scheduled runs operate ONLY if the module is in Auto mode with no Electrical Trip alarm
present.
• If the module is in Stop or Manual mode when a scheduled run begins, S2 is not
started (if configured as generator). However, if the module is moved into Auto mode
during a scheduled run, S2 is called to start.
• Depending upon configuration by the system designer, an external input can be used to
inhibit a scheduled run.
• If S2 is Off Load in Auto mode and a scheduled run configured to ‘Transfer to S2’ begins,
S2 is placed On Load for the duration of the Schedule.
