7.5 Function check of a pressure or temperature sensor
The error status of a sensor is displayed on the device as an event.
1 Switch to main display “Current events”.
2 Check the list for a current event with type 'E-3010' (temperature sensor failure) or
'E-3012' (pressure sensor failure).
Exchange the sensor involved when one of these errors is displayed → p. 132, §7.6.
If an error is not displayed, the sensor function can be checked by comparing the measured
value on the FLOWSIC500 with the measured value of a reference sensor.
7.6 Exchanging an external pressure or temperature sensor
7.6.1 Exchanging the pressure sensor
1 Three-way test valve: Move the lever to the test position (→ Table 21).
Test valve: Fit the adapter on the test connection (Part No. 2071841).
2 Unscrew the sensor from the three-way test valve.
Here, loosen the screw fitting slowly so that any overpressure can escape under control.
3 Loosen the plug-in connector cover.
4 Disconnect the plug.
5 Connect the plug to the M8 connection on the FLOWSIC500.
6 Screw the plug-in connector cover tight.
7 Install a new pressure sensor on the pressure measuring port marked “P
m
” → p. 61,
§3.5.2.
8 Enter the serial number of the new sensor in the FLOWSIC500 with the FLOWgate
TM
operating software.
– Connect to device, → p. 71, §4.3.1.
– Open the “Device Identification” tile in the “Parameter Modification” menu.
– Start the configuration mode.
– Enter the new serial number in the field “Pressure sensor serial number”.
– Return to the operating mode. The new serial number is written to the device.
Replace the gas flow meter in the device configuration with internal pressure
and temperature sensors.
WARNING: Hazard through wrong spare parts
The FLOWSIC500 and the delivered pressure and temperature sensors are
designed intrinsically safe.
▸ Only pressure and temperature sensors from SICK may be used → p. 138,
§8.2.2.
▸ The pressure and temperature sensors can be connected and
disconnected in the hazardous area as well.
▸ The pressure and temperature sensors may only be connected using the
M8 plug-in connectors marked accordingly on the FLOWSIC500.
▸ Modifying the electrical connection parts is not allowed.
NOTICE:
The pressure and temperature sensors can only be replaced when the
parameter locking switch is open.
