mA Output Failsafe (P219)
P219 mA Output Failsafe
Use for failsafe operation, independent of the Failsafe Material Level (P071).
Selecting an independent mA Failsafe option:
1. Press MODE to display the Auxiliary Function symbol.
2. Press ARROWS to scroll access the failsafe options.
3. Press ENTER when the desired option displayed.
Or, to produce an mA output at a specific value, enter the value required. This is used only
if mA output is allocated to a transducer (P201 = 1 to 4).
Standard Data Logging (P300 to P321)
All records can be reset by pressing the CLEAR keys.
Record Temperatures (P300 to P303)
These features display the high and/or low temperatures in °C. When a parameter
relating to a TS-3 Temperature Sensor is accessed, the Index Type display changes to the
TS-3 symbol .
If the unit is powered up without a temperature sensor connected, the value –50 °C is
displayed. This information can help trace problems with both built in and external
temperature sensors.
P300 Temperature, Transducer Maximum
Shows the highest temperature encountered, as measured by the temperature sensor in
the transducer (if applicable).
Press CLEAR keys to reset the log after a short circuit on the transducer wiring.
