Monitoring / Fault - Bottarini GDP21 Maintenance And Operating Manual

7. Putting the compressor into operation

7.5 Monitoring / fault

Danger
Interference with the automatic
monitoring system is not permitted.
Attention
Disconnect the battery or generator
only when the engine is not running.
In case of a problem
* Compressor temperature too high
*
Engine oil pressure too low
*
Engine temperature too high
* Battery voltage too low
* Fuel shortage (indicated by flashing
LED for insufficient oil pressure)
the system switches off automatically and
indicates the problem that caused the trip.
The fault indication goes off when
ignition switch S1 is turned to the
position. If the system is started without
elimination of the problem, it will stop
again after a function test and indicate the
problem.
Switch the system off if an oil mist is
entrained in the compressed air or if
excessive oil consumption is apparent
(see "Trouble-shooting")
Check whether operating pressure is
within the permissible limits.
Pressure gauge for display:
"Operating pressure"
Fig. 29
Danger
Do not operate the compressor at
pressures above the permissible
operating pressure.
The pressure gauge shows the
operating pressure of the compressor.
The permissible operating pressure is
indicated on the nameplate!
7.6 Operation
Danger
Only operate the compressor at the
permissible operating pressure and at
the permissible temperature.
Only use the compressor for its
intended purpose (see Chapter 2.2 of
this operating manual) in order to
avoid residual risk for persons and
assets.
Only operate the compressor in a safe,
functioning condition.
All components, hoses etc. fitted must
be of the correct size and designed for
the specified operating pressure and
temperature.
When working with compressed air,
wear suitable protective clothing (e.g.
protective suit, safety goggles, etc.).
(Off)
Wearing ear muffs may impair
communication between persons.
Warnings may not be heard. Inform
supervisor.
Check the compressor regularly.
Check the machine / installation for
external damage and faults at least
once per shift. Any changes noticed
(including changes in operating
performance) must be reported
immediately to the authority or person
in charge. If necessary, shut down and
secure the machine immediately.
Leaking condensation contains a
proportion of oil and must be collected
and disposed of under safe conditions.
Condensation must not enter the soil
or the rivers. Major quantities of
condensation accumulate particularly
in versions with aftercoolers for
processing compressed air. Provide a
collecting basin.
7.7 Shutdown
In order to shut down the compressor:
* Close air discharge valves. The screw
compressor reduces the speed of the
engine back to idling speed after the
preset final pressure has been
reached.
* Allow the screw compressor to idle for
a few minutes.
* Return the ignition switch (1) to the
position (Off-Aus).
Note
This switch can also be used as an
emergency stop switch. No other
switching off method is provided.
* Turn off power to the system using the
main switch.
After the installation has come to a
standstill all the air is automatically blown
out of the pressure tank via the blow-off
valve.
Danger
It is important that you ensure that the
pressure is completely blown off via
the blow-off valve.
Should this not be the case, open the
air outlet valves, identify the fault and
correct it.
7.8 Decommissioning
Fig. 30
If the system is to be closed down for a
longer period of time (approx. 3 months
or longer) the following preservation
measures must be taken:
*
Engine preservation (see separate
engine operating manual).
* Disconnect battery cables.
*
No special measures are required at
the compressor.
* Relieve the strain on tyres by jacking
up the vehicle.
* Check tyre pressure every 2 months.
* Release the handbrake.
Attention
When putting back into operation,
carry out the maintenance work
in accordance with Chapter 9
"Maintenance."
