TEMPERATURES OF CHILLED WATER OUTSIDE RANGE
Logical variable : DTEG
Incident codes KP02 : 1
KP07 icon :
Description
The input or output chilled water temperature measured by the sensor is outside the authorised range:
Water without glycol Water with glycol (maxi 30% glycol)
TEEG < TEGI ou TEEG > 65°C TEEG < -15°C ou TEEG > 65°C
TSEG < TEGI ou TSEG > 65°C TSEG < -15°C ou TSEG > 65°C
With :
TEEG ó Chilled water input temperature (°C)
TSEG ó Chilled water output temperature (°C)
TEGI ó Minimum chilled water temperature for evaporator (°C)
Action
F Immediate machine halt.
F The fault is displayed on the screen.
F The remote fault report is delayed for 6 minutes.
Resetting
Automatic fault resetting once chilled water temperatures return to normal operating range :
Water without glycol Water with glycol (maxi 30% glycol)
TEGI+2°C < TEEG < 60°C -10°C < TEEG < 60°C
TEGI+2°C < TSEG < 60°C -10°C < TSEG < 60°C
Trouble-shooting Solution
Sensor fault on input or output of chilled water.
Wiring fault or disconnection of sensor.
Replace sensor.
Check sensor connection.
