Main Technical Features - Crouzet CTR24-2251 Manual Del Usuario

DC versions:
Use shielded wires for the counting and control inputs
so as to obtain the maximum EMC resistance or con-
nect not used count inputs to ground (0 V).
AC versions:
Use shielded wires for the counting and control inputs
so as to obtain the maximum EMC resistance.
1.9 Is the device set and programmed correctly (func-
tion; for counters, max. counting frequency)?

with leading zeros suppression.
Overflow: In case of a display range overflow, the
counter starts again from 0, but without
removing the leading zeros and activating
all decimal points.
In case of a display range underflow, the
counter starts again from 0 and displays the
minus sign, without removing the leading
zeros and activating all decimal points.

1.10 Failure possibilities and causes
Impossible to use the keys:
- Key lock input activated
Counter does not count:
- Wrong or reversed wiring of the counting input
- Setting of an input signal not matching the pulse gen-
erator
- Polarity (NPN/PNP) reversed
- No ground connection between the pulse generator
and the counter
- Maximum counting frequency exceeded
- Signal levels do not reach the switching threshold of
the counter
If, despite all, your device still does not operate, contact
your local representative or call us directly for technical
support.
When sending your device back, please attach a short
description of the failure, of the programming and of the
connection diagram, in order to allow us to reproduce a
possibly existing defect and to repair your device as
quickly as possible.
