Setup and Operation 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. VAC switching power supply VAC switching power supply 2 relays / 2 transistors 1 relay / 2 transistors 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 The plug has to be disconnected from the counter before the cables are fastened by means of screws or screw-type terminals. After switching on, all segments and characters are illuminated for approx. 2 seconds; then the display changes over to the Display or Programming Mode. 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! 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 When programming the input level to TTL an addi tional protective circuit is necessary. We recommend the installation in an metallic environment. Prescaler 20 21
