Alarm codes:
each code is displayed in
sequence.
The codes are displayed
even if the alarm causes
have been removed; to stop
displaying them, turn the cp-
card off and then on again.
Alarm relay
The relay is normally open or
normally close depending on
DIP A2.
The relay action is cumulative:
• contact is closed (opened), if
at least 1 alarm is active.
• contact is opened (closed), if:
- all alarm causes have been
removed.
- all alarms have been reset,
either manually or automati-
cally.
Note: each alarm is not assi-
gned to the relay (see table
below)

Description & Causes
Electrode over-current
1. Water conductivity too high
(usually when starting after a
short stop)
2. High water level due to drain
valve malfunction
3. High water level due to fi ll
valve leakage
4. Electrode malfunction
No voltage at the electrodes:
with the unit on, no steam is
produced.
Internal memory error
High conductivity of the supply
water

Remedy
1. Drain part of the water and re-start.
2. Verify that the drain valve is properly working.
3. Check for any leakage of the fi ll valve when the humidifi er
is switched off.
1. Check the external command signal: type (V or mA)? Value?
Connections?
2. Switch off the unit and disconnect it from the mains: check
the internal electrical connections.
1. Download the proper default confi guration from HumiSet.
2. If the problem persists, contact APC customer service.
1. Switch off the unit and clean the conductivity sensor elec-
trodes.
2. If necessary, change the source of supply water or install a
suitable demineralizer such as a system that fully or partially
demineralizes the water.
Note: The problem will not be solved by softening the supply
water.
