TO ZERO CALIBRATE THE ULTRASOUND SENSOR
The sensor is zeroed by FläktGroup with an empty water tray.
If it is necessary to change the zero calibration to suit future
needs this can be done by adjusting position of the sensor by
means of the lock nuts.
The sensor must reach working temperature before calibration,
i.e. the humidifier must be allowed to run for at least 15 minutes
after switching on. The display may give a reading that is out by
a few millimetres during the warming-up period.
ALARMS
There is a potential-free group alarm output inside the junction
box. The alarms that appear on the monitor screen are:
Alarm level
The water level is continuing to rise above the maximum level
”A”. The most likely reason is that the solenoid valve MV1 is not
closing. The alarm stops after five minutes.
The water level does not reach the maximum level ”A” during
filling. The most likely reason is that the solenoid valve MV1 is
not opening, the water tap is turned off or the drain valve SV1 is
not closing. The alarm stops after 30 minutes.
The sensor has detected unreasonable values, outside its
detection rage, is not correctly aimed at the water surface or
has stopped working. This fault is also shown by the sensor
LEDs both glowing red. The alarm stops after five minutes.
Alarm CP1-Q1 or CP2-Q2
Has been initiated because the overload protection for circula-
tion pump CP1 or CP2 has tripped.
