OPERATING INSTRUCTIONS
21
7/73 - 10/53
STARTING THE MACHINE
•
Open the service valve fully, with no hose connected.
All normal starting functions are incorporated in the key operated
switch.
•
Turn the key switch to position 2 and hold for max 15 seconds to
allow the air inlet heater to reach working temperature.
•
Turn the key switch to position 3 (engine start position).
•
Release to position 2 when the engine starts.
•
Release to position 1 when the alternator charge light is
extinguished.
At temperatures below 0°C or is there is difficulty starting first time:
•
Complete starting sequence above.
•
Close service valve as soon as engine runs freely.
•
Do not allow machine to run for long periods with service valve
open.
•
Allow the engine to reach operating temperature. Then press button
(A) when fitted.
•
At this point in the operation of the machine it is safe to apply full
load to the engine.
TWO PRESSURE MODES OF OPERATION
1. The Low Pressure Mode is activated by turning the Hi/Lo Pressure
Switch to Lo. In this mode, the compressor will regulate according
to the air demand, between 0 and 7,0 m
3
/min at 6,9 bar regulated
set pressure. The regulated set pressure of this mode can be
changed (see Pressure Regulating Adjusting Instructions) from
5,5-6,9 bar.
2. The High Pressure Mode is activated by turning the Hi/Lo Pressure
Switch to Hi. In High Pressure Mode, the compressor will regulate
according to air demand, between 0 and 5,3 m
3
/min at 10,3 bar
regulated set pressure. The regulated set pressure of this mode can
be changed (see Pressure Regulating Adjusting Instructions) from
5,5-10,3 bar.
The mode of the compressor can be changed between the Low and
High at anytime. Engine speed will be lower at the HI Pressure Mode
setting.
Starting and stopping are unaffected by the selection and during
normal running the selector switch may be safely operated. Precaution
must be taken to ensure that downstream equipment is rated to suit the
available pressure.
The pressure guage indicates which setting has been selected.
STOPPING THE MACHINE
•
Close the service valve.
•
Allow the machine to run unloaded for a short period of time to
reduce the engine temperature.
•
Turn the start switch to the 0 (off) position.
•
Do not turn off the battery switch (if fitted) sooner than 70 seconds
after stopping the engine.
If the automatic blowdown valve fails to operate, then pressure must be
relieved from the system by means of the service valve(s).
EMERGENCY STOPPING
In the event that the unit has to be stopped in an emergency,
TURN
THE KEY SWITCH LOCATED ON THE INSTRUMENT PANEL TO
THE
0
(OFF) POSITION.
RE-STARTING AFTER AN EMERGENCY
If the machine has been switched off because of a machine
malfunction, then identify and correct the fault before attempting to
re-start.
If the machine has been switched off for reasons of safety, then ensure
that the machine can be operated safely before re-starting.
Refer to the
PRIOR TO STARTING
and
STARTING THE UNIT
instructions earlier in this section before re-starting the machine.
MONITORING DURING OPERATION
Should any of the safety shut–down conditions occur, the unit will stop.
These are:
•
Low engine oil pressure.
•
High airend discharge temperature.
•
High engine coolant temperature.
•
Alternator drive belt failure (warning message only).
•
Low engine fuel level.
DECOMMISSIONING
When the machine is to be permanently decommissioned or
dismantled, it is important to ensure that all hazard risks are either
eliminated or notified to the recipient of the machine. In particular:-
•
Do not destroy batteries or components containing asbestos
without containing the materials safely.
•
Do not dispose of any pressure vessel that is not clearly marked
with its relevant data plate information or rendered unusable by
drilling, cutting etc.
•
Do not allow lubricants or coolants to be released into land surfaces
or drains.
•
Do not dispose of a complete machine without documentation
relating to instructions for its use.
WARNING: Under no circumstances should volatile liquids such
as Ether be used for starting this machine.
WARNING: The sum of cranking time should not exceed 30
seconds within an interval of 2 minutes. If this limit is exceeded
the ECU will block cranking to protect the starter motor. Once
cranking is blocked the machine control system has to be
switched to diagnostic mode for at least 2 minutes. After this
interval cranking is possible.
NOTE:
Wear hearing protection at all times when the engine is
started with the service valve open and air is flowing from the valve.
NOTE:
As soon as the engine stops, the automatic blowdown valve
will relieve all pressure from the system.
CAUTION:
Never allow the machine to stand idle with pressure in the
system.
CAUTION:
To ensure an adequate flow of oil to the compressor at
low temperature, never allow the discharge pressure to fall below 3,5
bar.
