5.4.1 SERVICING THE FUSES AND
CIRCUIT BREAKER
The fuses and circuit breaker can both be
found on the inside of the control panel,
accessed with the shroud removed. Consult
Figure 5-2
for the location of the fuses and
circuit breaker. IMT recommends using a
fuse removal tool, though pliers will suffice
when removing the fuse.
Access the fuse and breaker locations by
opening the lid and locating the gauge panel
(See
Figure 5-2
).
5.4.2 SAFETY SHUTDOWN SYSTEMS
Protection for over-pressure and/or over-
temperature is provided. If either condition
should occur, the diverter valve should
activate to divert hydraulic fluid back to the
tank and the compressor will stop, the fault
reset on the instrument panel will pop out
and stay out until reset.
5.4.2.1 TESTING THE GAUGES’
SHUTDOWN FEATURE
Periodically (every 6 months or every 500
hours), the shutdown system should be
tested as follows:
Refer to
Figure 5-3
.
1. While compressor is operating,
close service valve and allow
compressor to unload
(approximately two [2] minutes).
2. Touch across button contact [
B
]
on gauge face to bezel [
A
]
(surrounding the respective
gauge) with an insulated
screwdriver.
DANGER
Adjustments should be made with
compressor switched OFF since electrical
terminals inside pressure regulator will be
exposed, and opening the canopy exposes
the belt drive system.
WARNING
Before performing maintenance:
Shut down machine, relieve all system
pressure and lock out all power, as per the
Safety Section of this manual.
NOTE THAT THE SYSTEM CAN BE
STARTED REMOTELY:
Always clearly tag the start-up
instrumentation against accidental system
start-ups during maintenance.
NOTE
It may be necessary to change the
compressor fluid and fluid filter more
frequently if the compressor fluid has water
contamination, or if the compressor system
is operated in a dirty environment.
WARNING
Before performing maintenance:
Shut down machine, relieve all system
pressure and lock out all power, as per the
Safety Section of this manual.
NOTE THAT THE SYSTEM CAN BE
STARTED REMOTELY:
Always clearly tag the start-up
instrumentation against accidental system
start-ups during maintenance.
IMPORTANT
Reason for shutdown should be
investigated before pressing reset.
WARNING
NEVER FORCE the reset button back into
position, or hinder it in any way, in order to
allow for machine operation. A tripped
reset button indicates a problem that
should be addressed and resolved before
operation can continue.
WARNING
Before making the contact connection [D]
between the test contact [B] and the bezel
[A], ensure that you are not touching the
machine to allow for grounding—only the
screwdriver should be making any
connection with the machine, and at the
contact points indicated.
