2.6 Safety and monitoring devices
General
The safety devices guarantee a high degree of operational safety, in conjunc-
tion with the BOGE monitoring system.
When one of the safety devices responds, the control system reacts as follows:
–
The compressor is immediately switched off.
–
A flashing fault number in the left field of the display indicates the cause of
the fault.
The following monitoring devices are standard for BOGE control systems:
Safety temperature
limiting device
The safety temperature limiting device switches off the compressor once the
maximum admissible final compression temperature has been reached. The
compressor does not switch on when dropping below the minimum tempera-
ture.
–
Rectify the fault.
–
Acknowledge fault by pressing
ENTER key
.
–
Switch on the compressor (
ON key
).

Monitoring the drive
motor
The drive motor is monitored by PTC resistors.
WARNING: Risk of injury!
Do not operate the compressor without built-in safety devices!
Do not dismantle the safety devices or put them out of operation!
The safety valve (1) on the
compressed air/oil chamber
prevents the maximum
admissible pressure being
exceeded.
WARNING: Risk of injury!
When the maximum pressure is exceeded (e.g. incorrect setting of the
operating pressure value), the entire delivery volume of the compressor is
ejected!
