Suction Pressure Transducer
Testing
The suction pressure transducer is located on the
suction adapter on top of the compressor. It
supplies pressure information to the SR-3
Microprocessor Control System. Alarm Code 87
(Check Suction Pressure Sensor) indicates a
possible problem with the suction pressure
transducer. The pressure reading can be monitored
with a Mechanics/Premium HMI Control Panel by
pressing the
G
AUGES
key. Check the reading by
comparing it to the reading on a low pressure
gauge attached to the suction service valve port.
Refer to the appropriate Microprocessor
Diagnostic Manual for more information about
the testing and operation of the suction pressure
transducer.
Suction Pressure Transducer
Replacement
Removal
1. Pump down the low side and equalize the
pressure to slightly positive. Make sure to
front seat the suction service valve to isolate
the low side.
2. Disconnect the wires and remove the suction
pressure transducer from the suction adapter.
Installation
1. Apply a refrigerant Loctite to the threads of
the suction pressure transducer.
2. Install and tighten the suction pressure
transducer and reconnect the wires.
3. Open the refrigeration valves and check for
leaks before placing the unit in operation.
