178
58
Phase Sensor Error
(Check Alarm)
• Occurs during pretrip (PTI) or function test only.
• During Phase Sensor Test, amperage difference
between correct and wrong condenser fan rotation
is more than 0.2 amps.
• Indicates:
• Defective phase relay
• Defective relay board
• Defective relay board cable No. 2
• Start a Function Test. During step F1.05,
check whether the phase relays on relay
board receive a signal (LED energizes). Verify
that the relays respond and shift to reverse
phase.
59
Delta Current Error
(Check Alarm)
• 100 percent ampere difference between current
phases.
• Indicates:
• Open connection on one phase of power supply
to a motor or heater element
• Enter Manual Function Test menu and test
(operate) each 3-phase component to locate
defective connection.
60
Humidity Sensor Error
(Check Alarm)
• Occurs during pretrip (PTI) test only.
• Relative humidity reading is less than 20 percent.
• Indicates:
• Sensor disconnected
• Wrong controller software configuration
• Defective sensor
• Check sensor connections.
• Check controller configuration for correct
humidity setting.
• Replace sensor.
68
AFAM Gas Analyzer Error
(Check Alarm)
• Gas analyzer circuit resistance is too high or too
low.
• Indicates:
• Sensor disconnected
• Wrong controller software configuration
• Short circuit to sensor
• Defective sensor
• Check sensor connections.
• Check controller configuration for correct
AFAM setting.
• Replace sensor.
69
Gas Analyzer Calibration (Check Alarm)
• Indicates possible CO
2
failure.
• Check sensor connections.
• Check controller configuration for correct
AFAM setting.
• Replace sensor.
