7.1
General
Troubleshooting of the Nortec GS 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 Nortec GS humidifier may require personnel to access the inside of the control
cabinet in the humidifier which may expose personnel and equipment to the hazards described below.
DANGER!
Risk of electric shock!
The
Nortec GS humidifier is mains powered. Live parts may be exposed when the access
panels are removed. Touching live parts may cause severe injury or even death.
CAUTION!
Electrostatic discharge (ESD)!
The electronic components inside the control cabinet in the humidifier are sensitive to elec
-
trostatic discharge (ESD).
Prevention:
Take appropriate measures to protect the electronic components inside the unit against
damage caused by electrostatic discharge (ESD). Refer to ANSI/ESD-S20.20.

Fault Indication
When a condition that is not normally expected occurs, it is detected by the control software and a warn
-
ing or fault message is displayed in the Service/Warning/Fault status area of the Home screen (refer to
). The warning and fault message types are described in
Table 13: Maintenance/Fault Status Descriptions
Message Type
Descriptions
Warning
A condition with a "Warning" status is active. Typically, these conditions are
of a temporary nature, or conditions that cannot cause damage to the sys
-
tem. Depending on the condition, the Nortec GS humidifier may be stopped
or remains operable (unless the warning relates to a control signal). If the
cause of the condition clears on its own accord, the warning message is
automatically reset. If the condition becomes worse, a fault message may
be triggered.
When a warning message is active, the status LED turns yellow in color.
Fault
A condition with a "Fault" status is active. Typically, these are conditions
which prevent further operation of the humidifier, or conditions that can
cause damage to the system. When a fault condition occurs, the Nortec GS
humidifier stops steam production immediately.
When a fault message is active, the status LED turns red in color.
