Level

Functions

Process

• To read out:

– the measured temperature

– the switching thresholds (high and low value)

– the value of the 4…20 mA output (transmitter only)

• To access the parameters and test menus of the configuration level

Configuration -

parameters menu

• To make the settings needed for operation:

– engineering units (international measuring units)

– transistor or relay output

– temperature adjustment

– 4…20 mA current output (transmitter only)

– 4…20 mA current input (transmitter only)

– selection of switching mode: window, hysteresis (see chapter “6.2. Function modes” on page 11.)

– selection of threshold value (see chapter “6.2. Function modes” on page 11.)

– filter

– 10 segment bargraph

Configuration -

test menu

• To test the configuration made in the parameters menu with input of a theoretical value

• To calibrate the expansion board in a transmitter version (4…20 mA current output and input)

6.2. Function modes

Temperature threshold detector

• Standard On/Off output

– 2 switching modes for the output, either hysteresis or window, inverted or not

Window mode

– Configurable delay before switching

– Possible outputs depending on the version: relay, transistor NPN, transistor PNP.

Temperature transmitter

• External setpoint

– The switching points are automatically adjusted by the 4…20 mA input signal originating from a PLC.

– On/Off relay output

• External setpoint

– This version delivers a 4…20 mA electric signal whose value is the image of the measured temperature

– On/Off relay output

– 4…20 mA output

– External setpoint (4…20 mA input).
