18.9.2. GENERATOR EXERCISE TEST
The TSC 9 controller contains an automatic generator exercise mode operating
feature. The exercise feature can be user configured to automatically start the
generator every 7, 14, or 28 days and operate it for 30 minutes (fixed) either
‘ON” or “OFF’ load (user configurable). Configuration settings are done using
PCB mounted jumpers. Generator starting times & days are automatically set
when the exercise mode is initiated via faceplate pushbutton.
Example: If the generator exercise mode is activated via the controller
pushbutton at 8:00am on Monday morning, the generator will automatically start
and operate for 30 minutes then will automatically stop. If the TSC 9 controller is
programmed for a 7 day schedule, the generator will automatically start at
8:00am Monday morning the following week (i.e. 7 days later) and run for 30
minutes then stop.
To change generator start time and day of exercising, the Exercise mode must
be canceled, and then reactivated at the desired start time and day.
NOTES
1. The TSC 9 contains a 24 hour power reserve feature to maintain exercise
timer settings in the event of power outages.
2. The load will automatically re-transfer to the utility supply should the
generator fail while in the test mode.
3. To bypass a 30-minute exercise run period, press and hold the Exercise
pushbutton on for 2 seconds until the LED remains on.
The Generator Exercise LED light will operate as follows:
LED ON - Exercise Timer is initiated, the 7, 14 or 28 day cycle timer is
active and the generator is in the off state.
