From Progressive Industries website:
High/Low Voltage Protection | Whenever AC power lowers below
104 volts, or rises above 132 volts, the EMS automatically shuts down
power to the RV. The EMS will monitor the power and once the AC
power rises above 104 volts, or drops below the 132 volt level the
time delay indicator flashes for the preset time and then automatically
restores power to the RV.
Time Delay for A/C Compressor | If AC power is interrupted or
the EMS detects a fault condition, the built in time delay is activated.
There are two settings on the EMS: one is 136 seconds (02:16), and
the other is 15 seconds. Consult your air conditioner manual to see if
it has a time delay built in. If so, use the 15 second delay, if not, use
the 136-second delay. The factory setting is 15 seconds.
