• Counting ranges h; min; s; h.min.s
• Optional optocoupler output
2. Inputs
INP A
Start input (depending on the input mode chosen)
INP B
Start/Stop or gate input (depending on the input
mode chosen)
SET/RESET input
Dynamic SET/RESET input. Linked in parallel to
the red RESET key. Resets the counter to the
predefined setting value.
3. Optocoupler output
(optional)
On active counting the output alternates at a
frequency of 1 Hz between active and inactive.
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
4.2 Switching on the 30 Hz filter
(INP A, INP B)
The filter provides input
damping*
30 Hz filter off
Start/Stop inputs not damped
30 Hz filter on
Start/Stop inputs damped for
use with me cha nical switches.
npn: switching for 0 V
pnp: switching for +U
B
Start/Stop via Inp B
counting while Inp B (Gate)
active (High level with pnp; Low
level with npn).
Count Start/Stop via INP B
(LOW-HIGH edge with pnp;
HIGH-LOW edge with npn).
Every active edge changes the
counter status.
Count start via INP A, stop via
INP B (LOW-HIGH edge with
pnp; HIGH-LOW edge with npn).
4.3 Input mode
Time unit: seconds (accuracy
depending on position of the
decimal point*)
Time unit: minutes (accuracy
depending on position of the
decimal point*)
Time unit: hours (accuracy
depending on position of the
decimal point*)
Time units: Hours:Minutes:Sec-
onds (decimal point setting is
ignored)
4.4 Operating mode
*0, 0.1, 0.01, 0.001 means: time measurement in
0, 0.1, 0.01, 0.001 time units
4.5 Decimal point
The decimal point defines the
resolution of the pro gram med
time unit.
0
no decimal place
0.0
one decimal place
0.00 two decimal places
0.000 three decimal places
Start/Stop via Inp B. counting
while Inp B (Gate) not active
or open
4.6 SET/RESET mode
manual reset via the red SET/
RESET key and electrical reset
via the SET/RESET input
no reset (red SET/RESET key
and SET/RESET input locked)
* where bounce occurs, e.g. with contacts
