Ametek Thermox Series 2000 WDG-IVC User Manual

6-4 | Thermox Series 2000 WDG-IV / IVC / IVCM
Span Gas Range Error Occurs if the calibration span gas does not read within the soft-
ware’s allowable limits. Once this error occurs, calibration of the
system is aborted.
This message could indicate one of the following problems:
•
•
•
•
•
•
•
Calibration gas setup problem
Process pressure incorrectly entered
Aspirator air not turned off during calibration (WDG-IV only)
Failed cell
Cell wiring reversed (Cell + and Cell - wires)
Leak in plumbing
Plugged plumbing
Temp Rise Failure Indicates that the sensor has failed to increase in temperature a
minimum of 10°C in a 60-second time frame during start-up. Once
the system reaches the operating set point, this message will only
occur if the sensor falls below the set point by 15°C and fails to
recover within 60 seconds. The problems that can cause this error
are as follows:
•
•
•
•
•
•
AC line power problem at the sensor
Open furnace
Over-temperature protection circuit trip on the sensor board
Sensor board failure
Loss of furnace drive signal
Interconnecting wiring problem
T/C (Thermocouple)
Circuit Failure
This message appears when the control unit recognizes a sudden
drop in temperature (greater than 100 °C). The thermocouple circuit
failure message can be the result of one of the following problems:
•
•
•
•
Shorted thermocouple
Faulty interconnecting wiring
Control unit display module failure
Sensor board failure
If this message is soon followed by a “Thermocouple Failure” message, see that message for
troubleshooting instructions.
Thermocouple Failure This error message occurs when the indicated sensor temperature
falls below -70°C. This error message can be the result of one of
the following:
•
•
•
Open thermocouple
Faulty interconnecting wiring
Control unit display module failure
Zero Gas Range Error Occurs if the calibration zero gas does not read within the software’s
allowable limits. Once this error occurs, calibration of the system is
aborted. This error indicates one of the following problems:
•
•
•
•
•
•
Calibration gas setup problem
Process pressure incorrectly entered.
Cell wiring reversed (Cell + and Cell - wires)
Aspirator air not turned off during calibration (WDG-IV only)
Failed cell (primary calibration should be run at this time)
Leak or plug in plumbing
