[Indication] / Problem Possible cause Remedy
WARNING LINE PRESS
The LINE PRESS is larger than the DESIGN
PRESS + 0.5 bar (7 psi) and simultaneously
a load request was given via the RS485
interface.
Suppress load requests via the RS485
interface if the LINE PRESS is higher
than the DESIGN PRESS + 0.5 bar (7
psi).
Pressure and temperature
indicator failed, indicator (----)
Ground fault or short circuit for sensor B1N,
B2N or R1F
Check fuses, changing if necessary
FAULT VSD COMMUNIC.
Communication to inverter disrupted, inverter
not responding
Check , Main contactor and ModBus
interface wiring
If no fault can be found, notify
Hydrovane service engineer.

Check for mechanical faults in the
compressor application.
Check the compressor motor is wired
correctly.
VSD configuration may have been
adjusted incorrectly
FAULT SPEED LOW
Speed is below permissible minimum speed.
