Potential Cause Check Remedy
x
Power supply is missing or polar-
ity is inverted
Check DL1 Led status and measure voltage on TB2 of PCB SRT_Power
Connect the 24VDC volt-
age to the transmitter
properly
x
Power_ON signal is missing
Close P1 link on PCB SRT_Power and make sure the Led DL2 lights on
properly
Replace SRT_Control
Board
x
Voltage supply is too low Check DL1 Led Status and measure voltage on TB2 of SRT_Power Board
Connect the 24VDC volt-
age to the transmitter
properly
x x x x
BNC video cable is interrupted Check electrical continuity and insulation from GND
x x
Video signal is low
Check video signal and data signal amplitude on TP1 (VD Out) of REI 2K
Board
Adjust amplitude properly
x x
Magnetron exhausted Check magnetron transmission hours and current Need check on console Replace magnetron
x x
The safety switch is open Check switch position and continuity
Close the safety switch or
replace it
x x
High voltage generator is dam-
aged
Disconnect 700V cable from TB3 of SRT_Power Board, disconnect mo-
tor cables, turn S1 of the SRT_Control Board on position 3 and make sure
DL3 is off.
Replace SRT_Power
Board
x x
Cable between Bearing Reader
and SRT_Control boards is
interrupted
Check electrical continuity of the cables Replace cable
