Lodar Soft Control Fault Codes
Your Lodar remote control receiver has a fault detection system built in to it. The fault codes are displayed by red LEDs, which flash a sequence of two numbers. The picture below shows the words 'FAULT' on the circuit board, with a lit LED next to it.
Picture 1 showing the fault code red LED lit.
During normal operation, the fault light is extinguished.
When a fault is detected, the Lodar receiver stops operating and displays the fault code by flashing.
The fault code is read by counting the flashes: it flashes the first number, then pauses briefly, then flashes the second number. Once the code is flashed, it will repeat the sequence.
For example, a “1-7” will indicate an undercurrent detection on Channel 7, normally this means no output is connected.
The fault codes are:
1-CH# : Load Under Current Detection (channel on for > 1sec and <100mA flowing)
2-CH# : Pre-Check Load short circuit detection
3-CH# : Load Short circuit detection whilst channel on
4-CH# : Open Circuit Driver (Output off when should be on)
5-CH# : Short Circuit Driver (Output on when should be off)
