Normal Operation
The LNKF800 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. STANDBY – Under the control of the Controller Module, the LNKF800
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
