4 Err or rectification
4.1 Safety Regulations
Attention
Important for RS compressors
Risk of electric shock from charged capacitors!
Always disconnect the system from the power supply
and then wait a further 10 minutes before touching
electrical components. The power capacitors take
this time to discharge.
4.2 Warnings
Warning messages are shown in the 3rd display row. The
red light signal on the HYDROVANE Pro flashes slowly.
Warning messages do not result in the compressor
shutting down. However ignored warnings may cause
faults.
4.3 Faults
In order to protect the unit, all detected faults result in the
compressor shutting down immediately or do not permit
the compressor to be started.
The faults are shown in the third display row, the red light
signal flashes quickly.
Faults must be rectified before re-start, and confirmed
using the key. The unit can now be started again.
4.4 Checklist
Loose connections, connection plugs, defective power
supplies or non-observance of installation notes generally
result in a large number of error patterns. It is therefore
not unusual for the errors shown to be traced back to
another cause.
Always observe the following checklist:
1. The unit's supply voltage must be within permissible
limits.
2. The control transformer must be set to any local
deviating mains voltages (see circuit diagram).
3. The switch panel temperature should be maintained
between -20 C (-4°F) and 55 C (131°F).
4. All remote controls fitted at a later date (remote
On/Off) must be managed without a connection relay
at max. 20 metres from the control cabinet.
5. When commissioning and carrying out maintenance
work, check that all connection screws and plugs are
tight.
6. The power supply must have adequate cross-section
cable, note the type of routing, cable length and the
conductor temperatures expected.
7. When retrofitting switching devices, the control
transformers must never be 'tapped' as they could be
overloaded.
8. Only ever use genuine Hydrovane spare parts.
9. Do not connect extra switching or measurement
devices without the consent of Hydrovane.
10. Do not route any measurement recorders out of the
unit.
11. For technical queries, please provide the following
information to assist with a quick and specific fault
diagnosis:
- Model type and serial number
- Circuit diagram drawing number
- Information about the unit's operating conditions
- Information on accessories fitted since purchase
(remote controls etc.)
- Other modifications/additions to your unit
- An accurate description of the fault.
