Safety Instructions
This manual is an essential part of the unit and contains important hints about
function, correct handling and commissioning. Non-observance can result in
damage to the unit or the machine, or even in injury to persons using the
equipment !
The unit must only be installed, connected and activated by a qualified electrician
It is a must to observe all general and also all country-specific and application-
specific safety standards

1. Applications
1.1. Dual level converter
In1
A, /A, B, /B, Z, /Z
A, /A, B, /B, Z, /Z
Both inputs can be individually set to either symmetric (differential) format using
A, /A, B, /B, Z, /Z channels, or to asymmetric (single-ended) format using A, B, Z channels only.
Acceptable input levels are RS422, TTL and HTL 10-30 volts.
The output format can again be selected individually for each output.
The outputs provide always all signals including the inverted channels, even when no inverted
signals are applied to the input.
With Control input 1 = LOW (or unconnected) and Control input 2 = HIGH the signal ways are as
shown in the drawing above, featuring two independent level converters.
1.2. Encoder splitter (dual output)
In1
Input 1 is used as encoder input, and Input 2 remains unconnected. The input can be set to
either symmetric (differential) format using A, /A, B, /B, Z, /Z channels, or to asymmetric
(single-ended) format using A, B, Z channels only.
Acceptable input levels are RS422, TTL and HTL 10-30 volts.
The output standard can again be selected individually for each output. The outputs provide
always all signals including the inverted channels, even when no inverted signals are applied to
the input. Control1 and Control2 remain unconnected with this application.
