The plug has to be disconnected from the counter
before the cables are fastened by means of screws
or screw-type terminals.
It is not allowed to contact the encoder to a direct
current line voltage without protective circuit for
EMC. For cable lengths > 30 m a protective circuit
is always necessary!
When programming the input level to TTL an addi-
tional protective circuit is necessary.
We recommend the installation in an metallic
environment.
Setup and Operation
Only valid for DC-Versions:
When switching on the device in PNP-Mode, a short signal is applied to inputs
A,B,C and the application input.
To suppress the pulse in TTL-Mode each input has to be connected to a resis-
tor of 10 kOhm/0,125W against 0V.
When switching on the device a short signal is applied to the application out-
put.
This pulse, if needed, is possible to suppress by connecting a resistor of 10
kOhm / 0,225 W against 0 V to the application-output.
3.3 Display
After switching on, all segments and characters are illuminated for approx. 2
seconds; then the display changes over to the Display or Programming Mode.
The display is available in five different versions:
Reflectiv: black figures on bright reflecting background
Transflective positive: black figures on back lighted ground
Transmissive white: white figures on black ground
Transmissive red: red figures on black ground
Transmissive green: green figures on black ground
