STARTING THE MACHINE
All normal starting functions are incorporated in the key operated
switch.
1. Turn the key switch to position 1 , the alternator charge light will
illuminate.
2. Turn the key switch to position 3 (engine start position).
3. Release to position 2 when the engine starts.
4. Release to position 1 when the alternator charge light is
extinguished.
STOPPING THE MACHINE
1. Close the service valve.
2. Allow the machine to run unloaded for a short period of time to
reduce the engine temperature.
3. Turn the start switch to the 0 (off) position.
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 air discharge temperature
• High engine oil temperature.
• Alternator/drive belt failure circuit.
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.
MAINTENANCE
General
Ensure all electrical equipment is properly maintained and controlled.
Ensure all earth connections are secure and regularly maintained.
Earth leakage circuit breaker (ELCB)
The earth leakage circuit breaker must be mechanically tested daily by
pushing the test button with the machine in its
no load condition . The
ELCB should trip to the off (down) position.
The earth leakage circuit breaker should also be tested every 3
months. A proprietary test meter should be used to induce live to earth
preset flow at each socket outlet. This current flow will produce the
required earth fault check. The test should be conducted in accordance
with appropriate national standards.
Instruments and controls
A Voltmeter is provided to indicate the output voltage.
Miniature circuit breakers provide over-current protection. In the event
of excess current the appropriate circuit breaker will trip to the
OFF
position.
WARNING: Under no circumstances should volatile liquids such
as Ether be used for starting this machine.
CAUTION: Do not start or stop the machine with the compressor/
generator mode switch in the generator position or the compressor/
generator position.
NOTE: 7/31E and 7/41 machines equipped with an 8,5kVA single
phase 110V generator have a three mode selector switch:
Position A selects operation of the compressor only.
Position B selects operation of the compressor and generator
together.
Position C selects operation of the generator only.
NOTE: Wear hearing protection at all times when the engine is
started with the top 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.
NOTE: The current trip rating is quoted at a nominal 40°C ambient
temperature.
An earth leakage circuit breaker provides additional protection in the
event of a leakage to earth in excess of 30 milliamperes on the
connected appliance or in the connections to the generator.
For alternator maintenance refer to Mecc Alte operation and
maintenance manual.
