Recommended measures or causes
Short-circuit at QRB
1. Check wiring.
2. Flame detector possibly faulty.
Check wiring
Test the contacts:
1. LMV27 connected to power: Fan output must be dead.
2. Disconnect power: Disconnect fan. No resistive connection between fan output and neutral
conductor allowed.
If one of the 2 tests fails, release the LMV27 since contact have definitively welded and safety can
no longer be ensured.

Make a reset. If error occurs repeatedly, replace the LMV27
Software version V03.10: If error C:99 D:3 occurs during standardization of the VSD, deactivate
temporarily function Alarm in case of start prevention (parameter 210 = 0, when using a release
contact) or interrupt the load controller-ON signal
Make a reset; if error occurs repeatedly, replace the LMV27
