Scheduler Operation; In Manual Mode - KIRLOSKAR DV Series O & M Manual

In Manual Mode

Contactor A may be controlled asynchronously from the running of the engine, in response to activity of the
auto start input.
If "Man Mde Con" is set to Yes, then Contactor A will be unloaded when the autostart is active, and loaded
when the autostart restores. The Unload delay is set by the Con A Unload Dly time. The Load delay is set
by the StartRestore time. This is to protect the A Contactor or the load from damage if mains voltages are
low.
A and B Contactors are also controlled when the engine is run manually if "Man Mde Con" is set to Yes.
Contactor A unloads at the start of Running
If the engine is started in Manual Mode, then Contactors A & B will operate as they do in the Auto mode.

4.11.7 Scheduler Operation

The unit allows the genset to be run at scheduled times for a specified duration. The scheduler runs
independently, but will only start when the unit is in the Auto Mode.
When the engine is running in Scheduler mode, the display shows "Sched" as its mode and a remaining
time in minutes.
If the load is to be transferred to the generator during a scheduled run, then the Sched Trans value should
be set to yes.
If the Scheduler requires the engine to be run when the unit is in test mode or manual mode, a Scheduler
warning is initiated. To run the engine in its scheduled mode, the engine must first be stopped with the
manual stop button. Once the engine has stopped the mode is changed to Auto with the mode button.
This will cause a Scheduler Lockout warning to occur. Pressing the start button will initiate the schedule
and start the engine. The engine will display "Sched" as its running mode.
If the Scheduler requires the engine to be run when the unit is running in auto mode, the engine will keep
running until the schedule run time has passed, and the autostart has restored. The scheduler will reset
for the next run time as normal.
If the scheduler requires a non loading schedule while running in Auto, the schedule will take over once the
Auto Start is deactivated
If the unit is in manual or test mode when a scheduled run is required and is set to Auto mode half way
through the schedule period, then the engine will run for the remaining schedule time.
