1. Description
• 6-digit display counter with SET/RESET-func-
tion
• Red LED display, character height 8 mm
• Display range from -199 999 to 999 999
• Leading zeros suppression
• Programming via two setting keys on the front
side
• During programming, the display guides the
user with text prompts
• Counter operating modes:
Count input INP A + count direction input
INP B (Cnt.Dir)
Differential count INP A – INP B (up.dn)
Totalising INP A + INP B (up.up)
Count Up/Down INP A 90° INP B x 1 (quAd)
Count Up/Down INP A 90° INP B x 2 (quAd2)
Count Up/Down INP A 90° INP B x 4 (quAd4)
• Optional optocoupler output
2. Inputs
INP A
Dynamic count input.
INP B
Dynamic count input.
2
SET/RESET
Dynamic SET/RESET input. Linked in parallel to
the red SET/RESET key. Resets the counter to
the predefined setting value.
3. Optocoupler output
Active if count value < 0. Simple preset counter
can be realized, when using subtract mode.
4. Programming routine
The programmable parameters of the device are
described below, in the order in which they can
be set. The device is fully programmed after one
pass of the routine.
The first values stated correspond to the factor
settings
4.1 Polarity of the inputs
npn: switching for 0 V
pnp: switching for +U
4.2 Switching on the 30 Hz filter
(INP A, INP B)
The filter provides input damp-
