OFF

DIP-switch B1: Setting the hour counter and maintenance alarm

OFF (default): hour counter and maintenance alarm enabled

ON:

hour counter and maintenance alarm disabled

(only if the DIP-switch B1 is

already ON before switching on the humidiﬁ er board).

Maintenance warning

After 2000 humidiﬁ er operating hours a warning is released, which is indicated by a ﬂ ashing red LED (7

short ﬂ a shes) and the intermittent activation of the alarm relay (only if no other alarms are active). The alarm

indicates the need for cylinder maintenance. However, the humidiﬁ er operation is still possible.

Maintenance alarm

After 3000 operating hours an alarm is released, which is indicated by a ﬂ ashing red LED (8 short ﬂ ashes)

and the steady activation of the alarm relay. The alarm indicates the necessary exchange of the steam cy-

linder. Humidiﬁ er operation is blocked.

Reset of the hour counter and the alarms

1. Set DIP-switch B1 to ON. After 5 seconds the alarm LED (red) and the operation LED (yellow) lights up

for 3 seconds (the alarms are still active and the hour counter is still in operation).

2. Set DIP-switch B1 to OFF. The hour counter starts from 0, and the alarms are cancelled.

The humidiﬁ er operation is enabled again.

Notice for counting the operating hours

The counting of the operating hours is proportional to the steam production, because the amount of lime

accumulating in the cylinder (a criterion for the cylinder exchange) depends on the steam production.

Example:

After 100 operating hours with 100% steam production the hour counter has counted 100 hours.

After 100 operating hours with 75% steam production the hour counter has counted 75 hours.
