2 Features
Connection of pre-defined valve types
Control of 1 valve
0...10V input for control of valve position (galvanically isolated)
Valve type selection by 2 rotary switches
Status display by LED
Safe valve position (open or closed) configurable by switch

Wurm GmbH & Co. KG Elektronische Systeme accepts no liability in case of improper use or use for
other than the intended purpose.
Target group
These instructions are intended for "service technicians".
Intended use
The SVD001/SVD101 is a control module for valves with bipolar stepper
motor drives, the specifications for which are given in the valve table.
WARNING
Danger to life from fire!
Switch off the power to the entire plant when carrying out installation, wiring or removal
work.
The wiring of the device must be carried out only by qualified electricians.
Use only the correct tools for all work.
Check all wiring after connection.
Take note of the maximum loads on all connections.
Never expose the device to moisture, for example due to condensation or cleaning
agents.
Take the device out of operation if it is faulty or damaged and is therefore
compromising
safe operation.
The device can have its own internal energy supply to supply it with power even without
external connections!
Do not open the device.
Do not repair the device yourself. If the device requires repairs, send it in with an exact
description of the fault.
CAUTION
Electromagnetic interference
can cause faults!
Always use shielded data cables and place them far away from power lines.

5 Installing
Fig. 3: Dimensions SVD001/SVD101
This device is designed for top-hat rail installation. The
housing is a standard size and is also suitable for
installation in fuse boxes or distribution switch boxes.
The devices can be positioned next to one another without
gaps.
To ensure a long life for the memory cells, we recommend installing the device in areas of the switch
cabinet that have a low ambient temperature and sufficient ventilation.
Fig. 4: Top-hat rail installations SVD001/SVD101
1. Place the module with the upper guide edge on the
top-hat rail.
2. Then press the module gently downward until it
engages with the fastening safety catch on the top-hat
rail.
NOTICE
When installing the device in the switch cabinet, please bear in mind the different
temperatures that may occur.
