1. Important information

Please read this manual completely and attentively before using the product for the first time. Keep this
manual. It is part of the product.
1.1 Safety instructions
Caution:
For installation tools are required.
Electrical hazard!
Never put the connecting wires into a power socket! Regularly examine the transformer for damage. In
case of any damage, do not use the transformer.
Make sure that the power supply is switched off when you mount the device and connect the cables!
Only use VDE/EN tested special model train transformers for the power supply!
The power sources must be protected to avoid the risk of burning cables.
1.2 Using the product for its correct purpose
This product is intended:
- For installation in model train layouts and dioramas.
- For connection to an authorized model train transformer (e. g. item 5200) or a digital command station.
- For operation in dry rooms only.
Using the product for any other purpose is not approved and is considered inappropriate. The manufac-
turer is not responsible for any damage resulting from the improper use of this product.
1.3 Checking the package contents

- 2 Screws
- 4 Plugs
- Manual

2. Introduction

The slow speed resistor, item 5216 has been especially developed for the use on model train layouts. We
want to your special attention to the integrated overload protection with indicator. The digital suitability
is limited, as modern locomotive decoders with load on track pass the resistor without braking. It is quite
easy to connect the module. You have to insert it only into the tracking current supply to the track.
You have to choose an individual resistance. The value depends on the necessary driving speed (fig. 1).
You can select the value by using the different sockets of the module.
In the connection diagrams of this instruction you can often see the above shown symbol. It describes a
wire connection. The wires which are crossing themselves have to be connected electrically at any point
on their way. So the connection point needs not to be exactly at the shown location. It can be moved e. g.
to a plug which is connected to one of the crossing wires.

3. Overload

The slow speed resistor, item 5216 has got an overload protection unit. If an overload is detected, the red
light turns on. First, you have to remove the cause of the overload and switch off the driving voltage. After
a cooling time of 1 – 2 minutes, the slow speed resistor is ready for use again.
