A. PRECAUTIONS/WARNINGS
1.
a. GREEN FLASH: indicates the unit is sending
information to the host computer.
b. YELLOW FLASH: indicates the host computer is
sending information to the unit.
c. RED FLASH: indicates a communications fault.
(figure 3.3I)
ALARM: when this light illuminates 'solid red', an
unacceptable condition has developed, at which time a 115
volt alarm output is generated for an external (factory or
customer installed) alarm beacon or buzzer. The visual
and/or audible alarm signal can be silenced by pressing the
START key.
(figure 3.4F)
PROCESS PRESSURE
GAUGE: indicates
process pump pressure.
REFRIGERANT HEAD
PRESSURE GAUGE:
indicates refrigerant
pressure on the
discharge side of the
compressor. The
refrigerant head
pressure is also the
condensing pressure
which is critical to
equipment efficiency. Head pressure on air condensed units
will vary with ambient temperature between 190-290 psi.
LOW PRESSURE GAUGE: indicates refrigerant pressure on
the suction side of the compressor. This pressure will
fluctuate with the operating temperature.
The operator must precisely follow all shut down
procedures outlined in this manual. If the operator fails to
follow precisely all procedures outlined in this manual, an
unsafe condition can develop resulting in damage to the
unit or personal injury.
