3.3 Assignment the signal inputs
Terminals 12 to 17 are AC optocoupler inputs. Terminals 12 (track A)
and 13 (track B) are pulse inputs for the main counter (XP) counting
function.
Terminal 14 is an external reset input for the main counter.
Depending on what is set in the programming mode (line 40),
terminal 15 serves as a starting input for the operating hours counter.
Terminal 16 (track B1) is the pulse input for the secondary counter
(XB). Terminal 17 is the input for resetting the secodary counter.
The main counter (XP) is reset by pplying an external signal (signal
width
≥
30 ms) at terminal 14; the secondary counter (XP) at terminal
17. While an external signal is present, no counter take place. The
method of resetting is set in the programming mode (lines 29, 30).
Assign terminals 12 to 17 accordingly. The maximum counter
frequency is selected in the programming mode (line 26).
Programming input logic The signal input logic can be programmed by means of a bridge bet-
ween terminals 18, 19 and 20, in accordance with the table below.
Electrical isolation is provided for instruments with an AC power
supply and a relay output without interface.

Apply
- if encoder supply
is not provided by
the counter.
- if the encoder is
featuring push-pull
or PNP output
- if several counters
are triggered in a
parallel way by one
encoder
- if the encoder is
featuring a NPN
output.
Encoder signals
PNP, triggered by
positive signals.
NPN, triggered by
negative signal.
