Bit Value Type Alarm Condition / Description and Suggested Corrective Action
5 32 Warning w: Sensor-Cal adjust problem
This condition indicates the sensor offset adjustment voltage has reached its
upper (90 %) or its lower (10 %) limit at the end of the sensor calibration.
This alarm will be set if, at the end of a sensor calibration, the sensor offset
voltage cannot be adjusted within the range of 10 % to 90 % in order to reach the
desired sensor Zero-Cal Signal Setpoint Target value (sensor dependent).
Corrective Action:
• From the Sensors dialog box, check the Zero-Cal Signal Setpoint Target
and Delta values for the specific sensor(s). Refer to the analyzer EEPROM
Data Sheets and check the factory-set Signal ZCAL Target ( Zero-Cal Signal
Setpoint Target ) and Signal ZCAL Delta ( Zero-Cal Signal Setpoint Delta )
values for the specific sensor(s) installed. If necessary, adjust them to the
values listed on the EEPROM Data Sheets.
Take appropriate safety precautions, open the Electronics Enclosures and Oven,
and:
• Check the cable between the sensor and J109 on the Customer I/O board
proper connections and inspect it for damage (cuts, nicks, burn marks, etc.).
•
Measure the sensor signal voltage at the corresponding terminals for the
sensor, at J109 on the Customer I/O board. For details on sensor wiring
assignments, refer to the Final “As-Built” Analyzer Customer Connections
drawing in the Analyzer Documentation Package.
If the sensor is faulty, replace the sensor. Contact AMETEK to verify sensor
operation, to order a new sensor, and/or to remove and replace the
sensor.
•
Replace the Micro-Interface board. Contact AMETEK to verify operation
before removing this board.
