• Verify whether the HeaterTemp value in the extended Temperature submenu
displays -75°C (-103°F). If so, the heating plate thermistor cable (or a
connector in the chain of connections) is the one causing the alarm.
• If the two above temperature readings are correct, execute the ForceSensor
Test command in the Service submenu. If the result is different than Good,
the sensor cable is probably the one causing the alarm.
2. Locate the corresponding cable and connectors in the Hydran 201Ti (see Section
3.4.6.2).
3. Verify thoroughly the chain of connections for this cable, including the
connectors.
4. Once the problem is fixed, execute the ForceSensor Test command in the Service
submenu to reset the H201Ti and cancel the alarm.
5. Wait at least two minutes.
6. Verify that the alarm has disappeared.
7. If applicable, verify that the corresponding temperature has returned to a normal
value.
