Switching the FXM from Line mode to Inverter mode

You can also force the FXM to operate in the inverter mode by manu-

ally turning off the input circuit breaker. Doing so will effectively dis-

connect any line power to the FXM, simulating a power outage which 

triggers the FXM to swtich to the inverter mode of operation.

Procedure

Turn off the input circuit breaker. The LCD shows 

1. 

INVERTER

, 

the status LED starts flashing to show the FXM is running on 

backup battery power. Confirm that the load is receiving power.

Switching the FXM from Inverter mode to Line mode

The FXM remains in inverter mode for as long as the input circuit 

breaker is turned off. Backup power is provided to the load until 

the batteries are drained to a preset level which triggers the FXM 

to shutdown automatically. If it is not necessary to operate the FXM 

in inverter mode, you should switch the FXM back to Line mode as 

soon as possible.

Procedure

Turn on the input circuit breaker. The FXM qualifies the line 

1. 

power. The LCD displays 

RETRAN

, then shows 

LINE

, 

BUCK

 or 

BOOST

. The status LED turns on.

  Note

 

If the FXM constantly switches between Inverter and Line modes due 

to a noisy line, the FXM’s input parameters should be broadened 

from normal to generator (See “Operating the Novus FXM, Sense 

Type.” on page 40. Also See Specifications, “Boost/Buck/Line 

Transfer Thresholds” on page 89).

In generator mode, the range of acceptable input frequency and volt-

age is expanded to accept the fluctuations created by a generator.
