ALARMS
LCD A 102 Indication Alarm description Effect / Symptom
PT2 INTERRUPTED
Steam generator temperature
sensor PT2 interrupted.
Control system detects interruption in PT2 and its
wiring.
Possible causes / Checks Solution
Problem with PT2 wiring –
check wiring.
Check condition of PT2 to electronic card wiring connection.
Problem with PT2
interruption – check sensor.
Look at cycle report to determine alarm intervention point.
Disconnect PT2 sensor from electronic card.
Check for continuity and measure resistance, which should be between 1000 and
1500 ohm.
Change PT2 - see technical datasheet ST01 - STEAM GENERATOR.
Problem with electronic
card.
Change electronic card.
