Herrmidifier Co 6000 Section V Troubleshooting Guide, Test Points, Maximum Capacity Setpoint

SECTION V TROUBLESHOOTING GUIDE

All Herrmidifier 6000 Series Humidifiers are manufactured under strict quality control and are subjected to a complete operational test. All circuit board adjustments are made at the factory and should not be adjusted beyond the guidelines set in this troubleshooting guide without first consulting a factory representative. The following information is for your help and reference. If you still experience difficulty after trying these remedies, contact your Herrmidifier representative.

WARNING!

The Herrmidifier 6000 Series Electronic Steam Humidifier cabinet was designed to house and shield the components from outside interference. Absolutely NO other components may be mounted inside or be electrically tapped into the humidifier without Herrmidifier's express written permission. Failure to heed this warning will void your warranty.

TEST POINTS

Each circuit board (See Figure 12) features three test points to aid in the troubleshooting process. Each of these test points works on a 0-4 VDC scale. “0 VDC” = 0%. “4 VDC” = 100%. All readings are between the test point and ground (Molex J1, terminal 11 [far right of molex connector, hours wire #11]).

Test Point #1:

Provides exact reading of drain threshold setting.

Test Point #2:

Provides circuit board reference voltage. Should always read 4 VDC +/-2%.

Test Point #3:

Provides actual percentage of output. For example, a unit running at 80% of maximum output would have a Test Point #3 to ground reading of 3.2 VDC.

Maximum Capacity Setpoint

The potentiometer labeled “R39" located in the top left- hand corner of the board allows adjustment of the unit's

NOTE

All blower units have their capacity set from the factory at 4 lbs/hr. These units can have their capacity increased by increasing the capacity adjustment potentiometer. Ensure there is sufficient air circulation in the conditioned space to prevent condensation on walls or ceiling when increasing capacity beyond 4 lbs/hr.

capacity in the range of 50-100% of maximum.
