182 ALARM
ULTRA: SUCTION PRESSURE SENSOR
ERROR
Prodigy provides 0-5VDC analog input for the suction pressure sensor. Sensor output is connected to P333, pin 1. valid
suction pressure range is 0 to 300 psig.
If Suction Pressure Sensor is detected on Ultra unit falls below the 30 psig then Prodigy will assume that the Pressure
Sensor sensor is faulty and ignore Pressure Sensor readings. alarm will automatically clear once input is within normal
operating range.
183 ALARM
ULTRA: COMPRESSOR 1 SUMP
TEMPERATURE SENSOR ERROR
Alarm will occur when an open or short condition is detected. Alarm will also occur when unit controller via the temperature
sensor detects an out of range. Valid range is 30°F to 150°F. Possible causes are faulty temperature sensor / circuit or
improper installation.
184 ALARM
ULTRA: COMPRESSOR 2 SUMP
TEMPERATURE SENSOR ERROR
185 ALARM ENGINEERING USE ONLY.
186 ALARM BLOWER MOTOR FAULT
In systems with EBM blower, prodigy shall start monitoring the motor alarm output (normally closed relay contact) ten
seconds after blower command is sent. The M3 unit controller will stop unit operation if fault conditions (relay contact open
logic input high) are detected.
Note: Motor alarm is wired in P2597; shared with VFD alarm and ECM blower rpm input. Alarm will clear when inrange
temperature is detected.
