WARNING
LogiCOLD microprocessor equipped units
may start automatically at any time the
START/RUN-OFF switch (SROS) is not in
the OFF position. Also, the unit may be fit-
ted with two way communication equip-
ment that will allow stating of the unit from
a remote location even though the SROS is
in the off position.
WARNING
Be aware of HIGH VOLTAGE supplied at
the power plug or from the generator.
When performing service or maintenance
procedures: ensure any two way commu-
nication is disabled in accordance with the
manufacturers instruction, ensure the
START/RUN-OFF switch is in the OFF posi-
tion and, whenever practical, disconnect
the high voltage source and disconnect the
negative battery connection. NEVER dis-
assemble the generator: HIGH MAGNETIC
FIELD INSIDE! This field can interfere with
cardiac implants such as pacemakers and
defibrillators.
WARNING
Under no circumstances should ether or
any other starting aids be used to start en-
gine.
WARNING
Ensure the power plug is clean and dry be-
fore connecting to any electrical out-
let/receptacle. Do not connect to any elec-
trical outlet without checking that it meets
the 380/3/50 and 16 Amp electrical re-
quirements of the unit.
WARNING
Always place SROS in the OFF position
and turn off the high voltage power supply
before disconnecting the high voltage
power plug from the unit.
WARNING
If the unit is in Standby Operation and
powered, voltage will be applied to high
voltage components (i.e. the fan motor
contactor) and those components will op-
erate (i.e. the fan blades will turn) when
those components are energized using
component test mode.
WARNING
Do not remove the cap from a hot radiator;
if the cap must be removed, do so very
slowly in order to release the pressure
without spray.
WARNING
Inspect battery cables for signs of wear,
abrasion or damage at every Pretrip in-
spection and replace if necessary. Also
check battery cable routing to ensure that
clamps are secure and that cables are not
pinched or chafing against any compo-
nents.
WARNING
Use the required protective eye wear and
clothing when working with solvents.
WARNING
Beware of moving poly V-Belt and belt
driven components.
WARNING
When working with belts, beware of pinch
points.
WARNING
The +5.0 VDC (terminal B) is common be-
tween the Compressor Discharge Pressure
Transducer, the Compressor Suction Pres-
sure Transducer, and the RPM sensor. If
this circuit is shorted to ground (due to one
of the mentioned components being defec-
tive, or a worn wire) the MessageCenter will
show
Suction Pressure: -1 bar (-14.7 psig)
Discharge
Pressure: 0 bar/psig
Engine RPM: 0.
WARNING
Before removal of the compressor, relieve
the internal pressure by very carefully
loosening the couplings to break the seal.
