6 Operation

After the device is powered on the operating mode is activated. The type of the signal can be

selected in the parameter in.t "Input signal". The complete list of the programming

parameters is shown in Table 7.2.

The input signal is digitalised, the square root calculated (if the function is enabled), the

signal scaled and displayed. The scale factor is calculated based on the parameter di.Lo

"Lower measuring limit" and di.Hi "Upper measuring limit". The display decimal point can be

specified in the parameters di.P.

For other signal processing functions see sections 6.1...6.3. For displayed errors see Table

6.1.

6.1

ON/OFF control is implemented with the NPN transistor output (see 5.1.2). The parameters

SP.Lo "Lower setpoint limit" and SP.Hi "Upper setpoint limit" specify the control limits. The

control function can be selected in the parameter Cnt:

−

Heating

−

Cooling

−

Alarm within limits

−

Alarm outside limits

The safe output state can be selected in the parameter out.E.
