Condair EL - Malfunction Troubleshooting Guide

68 Fault elimination
7.2 Malfunction list
Most operational malfunctions are not caused by faulty equipment, but rather by improper installation or
disregarding of planning guidelines. Therefore, a complete fault diagnosis always involves a thorough
examination of the entire system (e.g. hose connections, humidity control system, etc.).
Code Message Information
Warning Fault Possible causes Remedy
W01 E01 Smart Card No communication with SIM card.
No SIM card installed. Contact your Condair representative
SIM card defective. Contact your Condair representative.
W06 ––– Main missing
(displayed on exten-
sion unit)
or
Ext missing
(displayed on main
unit)
No communication between main unit and extension unit.
Bus cable between main unit and exten-
sion unit not connected or interrupted.
Check/connect bus cable.
Main or extension unit not switched on. Switch on main unit and/or extension
unit.
W07 ––– Ext Fault No communication between Linkup units.
Note: this message is shown only on Main units.
Extension unit(s) in fault condition. Check extensions unit(s).
W12 ––– On/Off Timer The humidier is turned off by the On/Off timer.
The On/Off timer is active and has
turned off the humidier.
No action is required..
W20 E20 Safety Loop External safety chain is open, humidication is stopped!
Note: as soon as the safety chain is closed again the Condair EL continues to
work normally.
Ventilation interlock open. Check/switch on fan of the AHU.
Air proving switch has triggered. Check fan/lter of the AHU.
High limit humidistat has triggered. Wait, check/replace high limit humi-
distat.
Fuse "F3" on the driver board defec-
tive.
Replace fuse "F3" on the driver
board.
––– E21
Max. Level Max. lling level of steam cylinder reached but no current.
Water conductivity too low (after initial
operation).
Wait until the mineral content of the
cylinder has increased
Water conductivity too low for type of
steam cylinder selected in the software.
Select correct steam cylinder type.
Phase failure heating voltage. Check service switch in the mains
supply line and switch on if applicable.
Check mains fuse(s) and replace if
applicable.
W21 –––
No Current Water level is at the top of the cylinder, or foaming was detected.
Humidier has lled to the top of the
cylinder without reaching demand.
No action is required.
For information purposes only: It is
normal for a new cylinder to reach the
maximum level before water in the
cylinder is concentrated, and for an old
cylinder to reach maximum level near
the end of its life cycle.
If the cylinder is new, add 1/4 tea spoon
(1.25 ml) of salt to the ll cup to raise
the conductivity level.
The conductivity of the water supply
may be too low.
Use potable water supply with conduc-
tivity greater than 150 μS/cm.
