Error Messages
In addition to the displayed error messages, the red LED “Alarm” lights up or flashes.
Alternate display of all error messages and operating displays.
Each occurred error is stored in the error history.
If the output AL/EV is programmed as the input valve EV (“draining” function),
there is no alarm contact available !
Error message “Voltage loss”
Message each time the unit is switched on, unit was without voltage.
After switching on or after voltage recovery, the controller starts with the basic status “operation”. Desalination carried out
prior to the voltage loss is not continued.
Check the plant for possible negative results of the voltage loss (e.g. drainage of the circuit due to an open motor valve).
All stored values, such as the water volumeter, remain even during a voltage loss. The real-time clock is battery buffered
and thus keeps on running.
Confirm the fault display via the “Alarm” key.
Error message “Des.val.OPEN”
You have activated desalination monitoring, desalination has been completed
but water still flows through the desalination valve after the programmed test
time (desalination monitoring). Triggering of desalination monitoring via contact
at the FC (flow controller) input. Depending on the programming, the alarm relay
is switched in addition to the display.
Adjust the test time to the closing or opening time of the valve when using motor valves.
Determine and eliminate the error and confirm the error message via the “Alarm” key.
Error message “Des.val.CLOSED”
You have activated desalination monitoring, desalination has been started but
still
no
water flows through the desalination valve after the programmed test
time (desalination monitoring). Triggering of desalination monitoring via contact
at the FW (flow controller) input. Depending on the programming, the alarm
relay is switched in addition to the display.
Adjust the test time to the closing or opening time of the valve when using motor valves.
Determine and eliminate the error and confirm the error message via the “Alarm” key.
