10 Fault Finding
10.1 Fault Finding
WARNING !
The Controller sequential logic monitors and checks the
compressor status through all stages of the operational cycle. At
each stage, the configuration and parameter limits set within the
Controller must be met for continued safe operation of the
compressor.
If faults occur they appear on the Controller display with a specific
code, the last character, E, A or R, identifies the fault type.
10.2 Shutdown Trip Error (E) – Menu P03
A shutdown error stops the compressor immediately or by normal
stopping sequence, preventing damage or a hazardous condition.
The error condition must be located and corrected, press reset to
cancel the error and the compressor can restart. Immediate
shutdown error codes have a first character of 0, normal stopping
sequence records 1 as the first character.
10.3 Alarm (A) – Menu P04
Alarms occur as a warning when normal operating conditions are
exceeded, but will not stop the compressor from being started and
run. General alarm codes start with a first character of 2, service
alarms begin with 4.
A service timer counts down from set values until a routine service
is due at 0 that sets off an alarm. A negative value count
continues until the timer is reset by maintenance personnel after
the required service.
10.4 Run Inhibit (R) – Menu P05
A run inhibit will prevent motor start until the fault is located and
corrected. With normal operational status restored, press reset to
cancel the error.
Further menus with restricted access codes are intended for
service level activities 1 and 2. These are reserved for use by fully
trained Hydrovane authorised service engineers.
We strongly advise that no attempt is made to access these
structures, continued safe operation may be impaired and/or
serious damage may occur.
