Fault Isolation

Condair TE

Fault Isolation

Troubleshooting of the humidifier must only be performed by well qualified and well trained personnel.

Electrical repairs must only be performed by a licensed electrician authorized by the customer or by

Condair service technicians.
Troubleshooting the humidifier may require the user to access the inside of the control and plumbing

cabinets in the humidifier, which may expose the user and equipment to the hazards described in

Your Safety” on page 5

.

7.1

General

Most operational warning/fault conditions are caused by improper installation, or by not adhering to

the suggested best practices for installation of the humidifier and system components. Hence, a full

fault diagnosis always requires a thorough examination of the entire system (hose connections, control

systems, etc.).

7.2

Fault Indication

When using a single remote controller to control multiple humidifier units, alarm signals will be output

individually from each humidifier unit via terminals 1 and 3. Alarm signals are output to the remote

controller when a unit’s safety protection function activates.
As a safety precaution, the unit stops operation, the alarm light illuminates on the remote controller, and

an alarm signal is generated (external signal output) when the following errors occur:

•

High water is detected in the drain pan

•

Water leak is detected in the humidifier.

•

Water solenoid valve is leaking.

•

Drain pump is not functioning properly.

•

Humidification module in the humidifier is expired.

Important!

Operation will be stopped for the humidifier unit that triggered the alarm. The remote

controller will display both a normal operating state and an alarm state simultaneously.

Alarms are indicated by the LEDs on the control unit, as shown

“Warnings and Faults” on page 30

. To find

the humidifier in question, press the Find button on the remote controller (refer to

“Finding the Humidifier that

Activated an Alarm” on page 13

for more details)

7.3

Resetting Faults and Warnings

The alarm is self holding, so the problem that triggered the alarm must be identified and resolved before

the alarm can be reset.

To reset the alarm:

1. Press the reset button BS1 on the control unit. Inspect the humidifier for further issues.
2. Turn OFF the power source to the humidifier (ex. turn off leakage current circuit breaker, or unplug

120 VAC outlet, etc).

Note:

Pressing the power button on the remote controller will not cancel the self hold.

3. Turn on the unit.
