12.1.19 Sensor Not Inst - GE Hydran 201 i Instruction Manual

• Alarm cause(s): The sensor sensitivity has dropped or the sensor is not functioning.
Replace the sensor as soon as possible.
Note: The Hydran 201Ti's H201 sensor is verified twice a month (the first and fifteenth
days of the month at midnight); the relevant parameters are recorded in the historic data
file Service. This test can also be performed manually using the ForceSensor Test
command (in the Service submenu), but no results are recorded. In both cases, one of the
two following messages is displayed if the test fails: Replace SensSoon or Replace
SensNOW.

12.1.19 Sensor Not Inst!

• Alarm type: Not applicable
• Non-abbreviated description: Hydran 201 sensor not installed
• Priority: Very high
• Parameter(s) involved: None
• Alarm cause(s): Problem with the H201 sensor
This message can only be displayed following the execution of a ForceSensor Test
command (see Section 4.5.4.2 on page 4-19).
Proceed as follows:
1. Ensure the serial numbers of the Hydran 201Ti (located at the back of the heating
plate) and the H201 sensor (located under the sensor connector) correspond to those
indicated on the shipping box and on the H201Ti's Test Certificate and Data Sheet.
For an example of certificate, see Figure 6-1 on page 6-4.
2. Verify whether the NewSensor submenu (Section 4.5.8 on page 4-25) contains the
value belonging to the corresponding H201 sensor.
3. Press CHANGE to "force" the installation of a new sensor.
Note: Each H201Ti is configured for a specific H201 sensor. If you receive more than one
H201Ti's, take the necessary precautions to not interchange the H201 sensors and the
H201Ti's.
