Figure 4-7 EAM LED and Audible Alarm Operation
Generator Set Supplying Load LED. Lights steadily to
indicate that the generator set is running and connected
to the electrical load.
When the test button is pressed to start a test, the LED
flashes slowly until the generator set starts and the ATS
transfers the load. When the Test button is pressed to
stop a test, the LED flashes slowly until the generator set
stops.
Fault LED. Lights steadily to indicate a system fault.

2 minutes after the Test button was pressed.
Audible alarm. The audible alarm can indicate that the
system is running or that there is a fault.
D System Running: The alarm sounds to indicate that
the generator set has been started by a remote start
command from the EAM. The alarm does not sound if
the system is running due to an exercise run or due to
an automatic start triggered by loss of the utility
power.
D Faults: The alarm sounds and the fault LED lights or
flashes to indicate power system faults or a low
battery in the alarm module. See Figure 4-7.

that allows programming of up to 8 on/off events per day.
Use it to program weekly exercise periods in addition to
the exercise time set through the ATS controller. The
timer mounts inside the ATS enclosure. See Figure 4-8.
