GE Hydran 201 i Instruction Manual page 219

• Non-abbreviated description: Cable open (not connected)
• Priority: Very high (repair cable immediately)
• Parameter(s) involved:
– CableOpen; SysOK Relay;FaultTrig. submenu; Section 4.5.7 on page 4-23
– No set point nor delay
• Alarm cause(s): Faulty connection with one of the following cables:
– Hydran 201 sensor cable
– Sensor thermistor cable (reading of -75 °C [-103 °F] during one minute)
– Heating plate thermistor cable (reading of -75 °C [-103 °F] during one minute)
Proceed as follows:
1. Identify the cable that triggers the alarm.
• Verify whether the SensorTemp value in the Temperature submenu displays -75 °C
(-103 °F). If so, the sensor thermistor cable (or a connector in the chain of connections)
is the one causing the alarm.
• 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 2.4.6.2 on page 2-10).
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.
