Parameters

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.

Primary Index mA output

Values

Range: 0.000 to 22.00

OFF * mA output responds to Failsafe Material Level (P071).

last known value is held until normal operation

resumes

LO produce the Empty mA output immediately

HI produce the Span mA output immediately
