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

SECTION V TROUBLESHOOTING GUIDE
All Herrtronic 6000 Series Humidifiers are manufactured under
strict quality control and are subjected to a complete operational
test before shipment. 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 TRION/HERRMIDIFIER representative.
WARNING!
The Herrtronic 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 TRION/
HERRMIDIFIER’s express written permission. Failure to
heed this warning will void your warranty.
TEST POINTS
Each circuit board (See Figure 7) 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, wire #11).
