Normal Operation 

 

The OFR400 Module has six LED’s on the faceplate: 

1.  OPERATING - Under normal operating conditions, this LED will flash 

GREEN when RF Data is present. 

2.  STAND BY – Under the control of the Controller Module, the OFR400 

Module has the ability to act as a duplex transmitter, sitting perpetually in 
Stand by Mode waiting for the primary transmitter to fail. This LED should be 
constant Amber. If a Fault should occur with the primary module, the “Stand 
by” unit will immediately become the primary unit, at which time the Stand 
by LED will be turned off and the LED’s will show an operating Module. 

3.  Transmit – This Green LED will be on when a signal is being transmitted 

4.  Receive – This Green LED will be on when a signal is being received 

5.  Program – This LED will be constant Amber when the unit is being re-

programmed by the Controller Module. This will signify that the unit is 
powered on but unavailable for use. 

6.  FAULT – Red LED, If the internal diagnostics for the module detect a 

problem, then this LED will remain on
