Describtion
The analog data encoder PCD7.L452 is used as a regulating encoder for manual setting of
manipulated variables e.g. for mixing valves, valve settings, temperatures etc.
Function describtion
The module offers three operation modes selectable by the three-position switch (ON, OFF,
AUTO). The switch position is signaled by the external control contacts B1 and B2.
Switch position “ON”
The regulating variable is selected with the front-mounted potentiometer. The 0 to 10 V
output signal is available at contact Y.
Switch position “AUTO”
The regulating variable is looped through without change to output Y via contact YR
These coupling modules are provided with spring clamp terminal blocks allowing easy and
quick wire termination. No tool is required to terminate solid wires and stranded wires with
end sleeves. And to terminate stranded wires without end sleeves just a screwdriver will do.
The terminated wires are easy to release with a screwdriver.

And/or distribution panels.
Installation
Electric installation and device termination shall be done by qualified persons only,
by respecting the VDE specifications and local regulations.
1. Power down the equipment.
2. Strip the wire by 10 mm. Wire cross section:
Solid wire
0.08 – 2.5 mm²
Stranded wire w/o end sleeve 0.08 – 2.5 mm²
Stranded wire with end sleeve 0.08 – 1.5 mm²
a) Solid wires and wire with end sleeves are plugged directly
Insert the wire straight into the contact and press until the wire snaps
In the spring.
b) When terminating stranded wires without end sleeves it is necessary
to open the spring with a flat-bladed screwdriver (blade width max.
3.0 mm): enter the screwdriver to the test sleeve situated below the
Contact and remove the screwdriver.
3. Device connection per wiring diagram.
4. Release a wire
Open the spring by inserting a flat-bladed screwdriver
(blade width max. 3.0 mm) to the test sleeve situated
below the conact and remove the wire.
5. Release the Module from the standard rail
Slightliy push the clamp at the bottom of the module with a flat-bladed screwdriver and
draw off upwards.
Connecting Bridge
The connecting bridge (Order-Nr. PCD7.L291) allows to interconnect up to 10 coupling
modules (total currenct max. 2 A).
Cut the needed number of contacts with wire cutting pliers at the respective predetermined
cutting point. Then insert the connecting bridge from the top into the contact slot and press
it downwards into place.
The tails of the connecting bridge carry potential, therefore
place the bridge in the middle of the aligned modules to
eliminate any accidential touch.
