Overview
Main technical features:
Display: LCD, 8 decades, height of the
figures 8 mm
Display range: 0 ... 99999999 with leading
zeros suppression
Display unit: 1 s
Max. frequency (Pulse/pause: 1:1):
12 kHz
Min. frequency: 1 Hz
Display refresh: 1 s
Measuring principle:
The tachometer operates via the
gate measuring method. The
incoming pulses are counted during
a measuring time of 1 s and recal-
culated in order to display 1/s.
Accuracy: < 0,05 %
Housing: Panel mounting, 48 x 24 mm
according to DIN 43 700,
RAL 7021
Panel cut-out: 22,2

Power supply: Non-replaceable lithium battery
(lifetime approximately 8 years at
20°C)
Working temperature:
–10 ... +55 °C, relative humidity <
85%, without condensation
Operating temperature:
–10 ... +60 °C
Storage temperature:
–20 ... +70 °C

1.9 Start-up
Is the device set and programmed correctly (function;
f
or counters, max. counting frequency)?
1.10 Failure possibilities and causes
Counter does not count:
-
Wrong or reversed wiring of the counting input
-
Polarity (NPN/PNP) reversed
- No ground connection between the pulse generator
a
nd the counter
- Signal levels do not reach the switching threshold of
t
he counter
If, despite all, your device still does not operate, contact
your local representative or call us directly for technical
s
upport.
When sending your device back, please attach a short
description of the failure, of the programming and of the
c
onnection diagram, in order to allow us to reproduce a
p
ossibly existing defect and to repair your device as
quickly as possible.
