Steam-Down Time Exceeded
The control activates the inlet solenoid valve at time intervals
when humidification is required. If the control has not activated
the solenoid valve in many hours despite constant demand for
humidification, the fault „Steam-down time exceeded“ appears
on the display.
Maintenance
The control also turns the humidity generator off after one hour
of operation with a full cylinder. The display reads „Mainte-
nance“. In most cases, maintenance must be done on the cylin-
der..
Main Contactor Fault
The control switches on the main contactor when demand for
humidification is present and the safety interlock is closed.
The control switches off the main contactor if the safety interlock
opens or if demand is no longer present.
If the control detects no current for at least 15 seconds, even
though the main contactor should be activated, the control sig-
nals „fault main cont.“.
The maximum water level message only displays if the main
contactor is switched on, i.e. when demand is present and the
safety interlock is closed. If the control registers maximum water
level for longer than 15 seconds, even though the safety inter-
lock is open or no demand is present, the control signals “fault
main cont.”.
