Computer Port
A serial cable from a computer is connected to the
download port to access the Data Logging
functions of the DAS. Refer to the DAS Data
Acquisition System Manual TK 50565 for more
information.
Printer Port
A serial cable from a printer is connected to the
printer port to print a report for the directly
connected DAS sensors. Refer to the Spectrum
DE Operator’s Manual TK 51299, or the DAS
Data Acquisition System Manual TK 50565 for
more information.
Unit Indicators
Receiver Tank Sight Glass:
The receiver tank
sight glass is used to check the amount of
refrigerant in the system, and the moisture content
of the refrigerant.
Compressor Oil Sight Glass:
The compressor oil
sight glass is used to check the relative level of
compressor oil in the compressor sump.
Air Restriction Indicator:
An air restriction
indicator is attached to the intake manifold.
Visually inspect the restriction indicator
periodically to assure the air filter is not restricted.
Service the air filter when the yellow diaphragm
indicates 25 in. of water column. Press the button
on the top of the restriction indicator after
servicing the air filter. Replace the EMI 3000 air
cleaner element (see “EMI 3000 Air Cleaner” on
page 66) at 3,000 hours or two years (whichever
occurs first) if air clean indicator has not reached
25 in.
Remote Status Light (Optional):
The remote status
light indicates the operating status of the unit. The
green “T” indicates the unit is functioning
properly. The amber “K” indicates the unit has a
check alarm but is still functioning. The green “T”
and amber “K” both flash to indicate the unit has a
shutdown alarm and is not functioning.
Unit Protection Devices
Fuse Link (Current Limiter):
The fuse link is
located in the positive battery cable. At a current
draw of approximately 110 amps, the fuse link
will melt, cutting all power to the unit. If the fuse
link burns out, check for a grounded 2 wire before
replacing the fuse link. Replace the fuse link by
replacing the positive battery cable.
Fuses:
A number of fuses, located on the relay
board, protect various circuits and components.
See “Fuses” on page 46 for more information.
High Pressure Cutout:
The high pressure cutout is
a pressure sensitive switch that is located in the
compressor discharge manifold. If the discharge
pressure rises above 470 psi (3241 kPa), the
switch opens the 8D circuit to the fuel solenoid,
which stops the engine.
