until the probe has been properly installed (see the
following section).
2.5 Installing the Probe
Probes are usually installed in a sample system to protect them from any
damaging elements in the process. The probe is mounted in a cylindrical
container called the sample cell, which is included as part of your sample
system.
Probes are mounted into the sample system or process line with 3/4-16
straight threads that are sealed with an o-ring. Other fittings are available
for special applications.
!
CAUTION! If the probe is to be mounted directly in the
process line, without a sample system, consult the factory
for proper installation instructions and precautions.
Refer to Figure 24 on page 18, and complete these steps to install the probe
into the sample cell:
1.
Insert the probe into the sample cell and thread the probe into the
sample cell fitting. Make sure you do not to cross the threads.

two-wire shielded cable. When connecting the probe, protect the cable from
excessive strain (bending, pulling, etc.) and do not subject the cable to
temperatures above 65°C (149°F) or below –50°C (–58°F).
Note: Standard factory-assembled cables are available in lengths up to
600 meters (2000 feet).
Figure 28: Two-Wire, Shielded, Aluminum-Oxide Moisture Probe Cable
To connect the probe cable, refer to Figure 25 on page 19 and Figure 29 and
Figure 30 on page 22, and complete the following steps:
1.
Insert the end of probe cable with the bayonet-type connector onto the
probe and twist the shell clockwise until it snaps into a locked position
(approximately 1/8 turn).
IMPORTANT: Ensure that the power is off before proceeding.
2.

Connecting the High/Low Alarms (A and B)
IMPORTANT: Ensure that the power is off before proceeding.
Each of these alarms can be set to trip on either a high or low condition. For
a high alarm, the alarm will trip if the input exceeds the setpoint. For a low
alarm, the alarm will trip if the input drops below the setpoint. Make
connections to the Alarm A and Alarm B upper terminal block on the back
of the Single-Channel Hygrometer, as shown in Figure 25 and Figure 26 on
page 19.
IMPORTANT: To maintain good contact at each terminal block and to avoid

2.6.4b
Connecting the Fault Alarm
If enabled, the fault alarm trips when one or more of the following faults
occurs:
• power failure
• range error (configurable)
• watchdog function system reset
Note: The watchdog function is a supervisory circuit that automatically
resets the unit whenever a system error occurs.
The fault alarm may operate in fail-safe mode and uses pins 2 and 3 to
provide a “normally closed” contact. When the Single-Channel
Hygrometer is operating in a non-fault state, the fault alarm relay is
energized to open the contact between pins 2 and 3. When a fault occurs, the
fault alarm relay is de-energized to close the contact between pins 2 and 3.
Note: The contact between pins 1 (normally open) and 2 works in the
opposite way. The alarm is energized to close the contact during
ordinary operation and the alarm is de-energized to open the contact
when there is a fault.
IMPORTANT: Ensure that the power is off before proceeding.
To wire the fault alarm, make connections to the upper terminal block on
the back of the Single-Channel Hygrometer, as shown in Figure 25 and
Figure 26 on page 19.
IMPORTANT: To maintain good contact at each terminal block and to avoid
damaging the pins on the connector, pull the connector
straight off (not at an angle), make cable connections while the
connector is away from the unit, and push the connector
straight on (not at an angle) when the wiring is complete.

4.1 Introduction
The Single-Channel Hygrometer is designed to be maintenance and trouble
free. However, because of severe process conditions and other factors,
minor problems may occur from time to time. Some of the most common
problems and recommended maintenance procedures are discussed in this
chapter. If you cannot find the information you need in this chapter, please
consult GE for help.
!
CAUTION! Do not attempt to troubleshoot the
Single-Channel Hygrometer beyond the instructions in this
chapter. If you do, you may damage the unit and void the
warranty.
This chapter covers the following topics:
• common problems
• replacing/recalibrating moisture probes
• cleaning the front panel
Proceed to the appropriate section to perform any of the above tasks.
4.2 Common Problems
If the Single-Channel Hygrometer measurements read too wet or too dry, or
if they do not make sense, there may be a problem with either the probe or a
process component. Use the descriptions of common problems in Table 3
on page 82 to troubleshoot and solve such problems.
Single-Channel Hygrometer User’s Manual

Possible Cause
Response and Action
Symptom: The accuracy of the moisture sensor is questioned.
There is insufficient Response: Reads too wet during dry down conditions

equilibrate.
Action: Change the flow rate. A change in dew point
indicates the sample system is not at equilibrium or
there is a leak. Allow sufficient time for sample system
to equilibrate and moisture reading to become steady.
Check for leaks.
Dew point at the
sampling point is
different from the dew
point of the main
stream.
Response: Reads too wet or too dry.
Action: Readings may be correct if the sampling point
and main stream do not run under the same process
conditions. The different process conditions cause
readings to vary. If sampling point and main stream
conditions are the same, check sample system pipes,
and any pipe between the sample system and main
stream for leaks. Also, check sample system for
adsorbing water surfaces, such as rubber or plastic
tubing, paper-type filters, or condensed water traps.
Remove or replace the contaminating parts with
stainless steel parts.

Single-Channel Hygrometer User’s Manual
Chapter 4. Service and Maintenance
4.3 Replacing/Recalibrating Moisture Probes
For maximum accuracy, moisture probes should be returned to the factory
for recalibration every 6–12 months, depending on the application. Under
very severe conditions, more frequent calibrations are recommended
However, under very mild conditions, less frequent calibrations are
necessary. Contact an applications engineer for your specific recommended
calibration frequency
All new or recalibrated moisture probes must be installed in accordance
with the instructions in Chapter 2, Installation.
IMPORTANT: To maintain good contact at the terminal block and to avoid
damaging the pins on the wiring connector, pull the connector
straight off (not at an angle) the terminal block. Then, make
the cable connections while the connector is off the unit.
Finally, after the wiring is complete, push the connector
straight onto the terminal block (not at an angle).
After the probe has been installed and wired, enter the probe calibration
curve data as described in Chapter 3, Operation and Programming. Each
probe is shipped with its own Calibration Data Sheet, which includes the
serial number for that probe.
