Chapter 3 Alarm Indication and Troubleshooting
Cause / Remedy
(Press the reset key after eliminating the cause.)
The timing of a periodical check is informed.
Recommended to ask for the check and service of the
pump, fan motor and compressor.
Contact input is detected.
・Check if the leakage sensor is connected.
・Leakage occurred. Check the leakage point.
Electrical resistivity/conductivity is larger than the set
value.
If an electric conductivity sensor is used, replace the DI
filter.
Electrical resistivity/conductivity is smaller than the set
value.
If an electric resistivity sensor is used, replace the DI filter.
・ Check if the electric resistivity/conductivity sensor is
connected.
・ There may be short circuit or open wire of the
resistivity/conductivity sensor. Replace the sensor.
