Error description WTS LARGE +0300131IT rel. 1.0 - 05.09.2022
12. ERROR DESCRIPTION
If an error appears, the permeate production stops. The display in the control panel switches
from the current display to the display of an error code.
List of possible faults and error codes
Alarm indication on the display Possible cause Action
ALARM - CONDUCTIVITY
The conductivity measuring instrument
has lost calibration or is no longer working
correctly.
Recalibrate or replace the conductivity sensor.
The feed water parameters have changed. Contact your supplier or the manufacturer.
High permeate conductivity due to blocked
membrane(s).
Replace the membrane(s).
Piping blocked Eliminate the cause of the blockage.
Delay time too short
If the error occurs after a module flush, chan-
ge the delay time in parameter 3D. If the error
occurs during production, adjust parameter
4C.
Conductivity limit value chosen too low
Check the conductivity limit value entered.
Adjust if it`s necessary. Note the technical data
of the consumer / humidifier.
SYSTEM STOP - HIGH PRESSURE
The PS
HIGH
overpressure switch for the max.
permissible operating pressure has switched.
Only for ROC 140 an ROL units
The PSHIGH pressure switch is not calibrated
or is not working correctly.
Replace the pressure switch.
Water pressure too high. Re-adjust the pump pressure.
Membrane(s) is/are blocked. Replace membrane.
SYSTEM STOP - NO PRESSURE
The PS
LOW
overpressure switch for the min.
permissible operating pressure has switched.
The PSLOW pressure switch is not calibrated
or is not working correctly.
Check an existing pre-treatment (if any).
Replace the pressure switch.
Decreasing flow rate. Blocking of filter
cartridges..
Replace them.
Water pressure too low.
Check the function of the solenoid valve.
Check the water inlet pressure.
System STOP - DOS PUMP
(only for systems with dosing pump)
Dosing pump does not work.
Check the fuse and replace it if necessary .
Dosing pump is not working, replace it.
Dosing pump does not work, the magnet
"knocks".
The suction filter in the anti-coating canister is
blocked. Clean the filter.
Dosing pump does not work, the magnet
does not "knock" or only damped.
Dirt deposits in the valve or valve is blocked.
Replace the dosing pump.
The red LED in the display of the dosing pump
lights up.
Level alarm. Refill with anti-calant.
