9.1.1 Cable types and length
9.2 Power supply connection
1. Connect the plugs to the rear of the device.
2. Ensure correct orientation.
3. Connect the protective earth conductor (PE) to
terminal 26.
4. Connect the neutral conductor (N) to terminal 25.
5. Connect phase (L1) to terminal 24.
6. Switch the device on and off by switching the
power supply on and off accordingly.
The device itself does not feature a separate on/off
switch.
9.3 Current inputs and outputs
9.3.1 Current input 1 (measured value)
The signal from a measuring amplifier or transmitter
which determines the actual value of the measured
variable is connected to current input 1.
1. Connect the + conductor to terminal 2.
2. Connect the - conductor to terminal 1.
3. Connect the screen to earth (PE) at one end.
9.3.2 Current input 2 (disturbance variable or
command variable)
The signal from a measuring amplifier or transmitter
which specifies the disturbance variable or command
variable is connected to this current input.
1. Connect the + conductor to terminal 4.
2. Connect the - conductor to terminal 5.
3. Connect the screen to earth (PE) at one end.
9.3.3 Current output 1 (measured value)
Current 1 output outputs the displayed measured
value as an analog current (0 (4) to 20 mA).
Use of current signal:
•
As input signal for another indicator.
1. Connect the + conductor to terminal 6.
2. Connect the - conductor to terminal 7.
3. Connect the screen to earth (PE) at one end.
9.3.4 Current output 2 (position of feedback
potentiometer)
Current output 2 outputs the position of the feedback
potentiometer of the final control element as an
analog current (0 (4) to 20 mA).
Use of current signal:
•
As input signal for another indicator
1. Connect the + conductor to terminal 13.
2. Connect the - conductor to terminal 14.
3. Connect the screen to earth (PE) at one end.
9.4 Feedback potentiometer of the final
control element
1. Connect terminal 9 to the "Start" connection
(0 %).
2. Connect terminal 10 to the "End" connection
(100 %).
3. Connect terminal 8 to the "Wiper" connection.
4. Connect the screen to earth (PE) at one end.
