6.4.2. Combined Input Channel (C4)

Highlight channel C4 in the channel menu and press :

The combined input channels can be used for sensors with analog or frequency output signal. The

channel is set by selecting the appropriate signal type.

Use the arrow keys to highlight a menu item and press

to modify the value/setting. Different menu

items will be displayed, dependant on the use of the combined input channel.

Use as analog input channel (left image)

The configuration is the same as that of the analog input channels C1 … C3 described in section 6.4.1

on page 22.

Use as frequeny channel (center image)

Meas. variable type and units of the measurand of the sensor connected to this channel

Index Variable identic variables are indexed automatically

Name enter the desired name of the channel

Signal type select the signal type of the connected sensor: frequency either with or

without direction detection

Calibr. value enter the factor used to multiple the frequency value to calculate the

measured value (e.g. the number of cogs when measuring the rotational

speed at a cogged wheel)

Linearisation here you may enter or select a linearisation table to reduce the

linearisation error of the sensor (see explanations in the section „How to

use a linearisation table“ on page 23)

Use as counter channel (right image)

Meas. variable type and units of the measurand of the sensor connected to this channel

Index Variable identic variables are indexed automatically

Name enter the desired name of the channel

Signal type select counter either with or without direction detection

Pulse value enter the volume that shall be calculated for each counting impulse (e.g.

the geometric tooth volume for gear flow meters)

Linearisation here you may enter or select a linearisation table to reduce the

linearisation error of the sensor (see explanations in the section „How to

use a linearisation table“ on page 23)

Press

after finishing the inputs to save all settings.
