The Exercise LED flashes at a rate of twice per second for 5 seconds and then goes out to signify that
repeat exercise periods are cancelled.
4.5.3.4 Canceling An Active Exercise Period
Active exercise periods can be cancelled by pressing the Override pushbutton on the control panel or by
grounding the remote override input on the back of the control panel.
4.5.3.5 Power Source Failure During An Active Exercise Period
If either power source fails during an active exercise period, the control immediately terminates the
exercise and proceeds with the automatic mode of operation.
4.5.3.6 Exercise With Load Sequence of Events
1. When an exercise period becomes active, the Exerciser LED flashes at a rate of once per second.
2. The control signals the generator to start.
3. When the generator output is acceptable, the control transfers the load to the generator, following
the configuration set points.
4. After the exercise period has ended, the control retransfers the load back to the utility, following the
configured set points.
5. Once the load is connected to utility power, the control runs the generator set unloaded for the
duration of the cool-down timer (TDEC).
6. After the TDEC timer expires, the control signals the generator set to stop.
7. Unless the repeat exercise periods have been cancelled, the Exercise LED quits flashing and
remains on to signify that repeat exercise periods are set. If the exerciser is not set up to repeat
exercises, the Exercise LED goes out.
4.6 External Exercise Clock Option [TR 610 top2]
The optional external exercise clock includes a real-time clock that keeps track of the time and date. The
7-DAY exercise clock can be set for automatic changeover for summer/winter (daylight savings/standard)

operation.
Up to 56 programs are available to set exercise start and stop times. One program is required to start an
exercise period and a second one is required to stop an exercise period.
The exercise clock has a built-in test feature that can be used to initiate an exercise that has not been
programmed or cancel a programmed exercise in process.
