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.

value. Press Enter to save (or Cancel to keep the previous value).

Trimming is complete. Accuracy can be verified using the Test Menu, above.

Example: Trim is reset, then Trim Zero is selected. The SCADA input reports 3.977 mA. The operator enters “3.977” as the Zero Trim value. Trim Span is selected. The SCADA input reports 19.985 mA. The operator enters “19.985” as the Span Trim value. The Single-Channel Hygro meter will adjust the output accordingly to true the output as read by the customer recorder, SCADA or DVM. Using the Test Menu, the operator verifies that a test value of 0% now reads

4.000 mA at the SCADA equipment, and a test value of 100% now reads

20.000 mA.

Chapter 4. Service and Maintenance

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 81

Page 92

Chapter 4. Service and Maintenance

Table 3: Troubleshooting Guide for Common Problems

Possible Cause Response and Action

Symptom: The accuracy of the moisture sensor is questioned.

There is insufficient time for the system to equilibrate.

Response: Reads too wet during dry down conditions or too dry in wet up conditions. 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 ti me 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 poin t

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.

Sensor or sensor shield is affected by process contaminants

Sensor is contaminated with conductive particles.

Response: Reads too wet or too dry Action: Clean the sensor and the sensor shield, then

reinstall the sensor.

Response: Reads high dew point. Action: Clean the sensor and the sensor shield, then

reinstall the sensor. Also, install a proper filter (i.e. sintered or coalescing element).

Sensor is corroded Response: Reads too wet or too dry

Action: Return probe to factory for evaluation.

Stream particles causing abrasion.

Response: Reads too wet or too dry. Action: Return probe to factory for evaluation.

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 connec tor 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.
