1.TROUBLESHOOTING NH ELECTRODE STEAM HUMIDIFIERS

A.PREPARATION

(1)Ensure the installation detail conform to installation requirements.

(2)Understanding the Principle of Operation and the software menus is an asset when troubleshooting. This information is found in chapter 10-20 Operation and can be elaborated on by your local representative.

(3)When contacting your local representative or NORTEC for troubleshooting assistance, please ensure the serial number has been obtained for reference purposes.

(4)Whenever the troubleshooting steps indicate a problem with the main pc-board, first check all connections at the main PCB (including the ribbon cable connections at the center of the main PCB) before ordering replacements.

B.STARTING POINT

(1)Table 1 checkpoints will allow for faster troubleshooting. Ensuring that all these steps are taken is good practice when beginning to troubleshoot the NH series humidifier. Check your symptom and verify all points before ordering any replacement parts or contacting your local representative. Use the wiring diagram when necessary for clarification.

NOTE

Wiring diagrams on unit supersedes diagrams in this manual.

WARNING

BE AWARE, WHEN TROUBLESHOOTING, THAT THE HUMIDIFIER IS

POWERED BY HIGH VOLTAGE AND FAMILIARITY WITH BOTH GOOD

PRACTICES AND WIRING OF THE HUMIDIFIER IS RECOMMENDED.

ANY TROUBLESHOOTING THAT REQUIRES OPENING THE CABINET

SHOULD BE DONE BY QUALIFIED PERSONNEL.

C.NHTC/NHPC

(1)The self-diagnostic system built into the NHTC is continually checking the status of the electrical circuits to the fill valve, drain valve, primary voltage contactor, high water sensor and steam cylinder. The modulating signals from external humidistat and reduced manual capacity settings are taken into consideration. When problem symptoms are found, the NHTC/NHPC will take self-corrective actions, if applicable. It will, if necessary, respond by shutting itself down. Table 3 describes some of the conditions the NH unit can detect and warn or protect itself against. Table 4 contains a definition of the terms used in this section.
