Operating Instructions
Electronic Preset Counter
Type CXE 322, CXE 822
1. Description
– 6 digit preset counter, 2 presets, add./subtr.
– bright 2-line LCD display with symbols for activated ou-
tputs and current preset values
– count and preset range – 999999 to 999999, over- or
underflow without count loss up to 1 decade (will be in-
dicated by flashing of the display with 1 Hz frequency)
– programmable to operate as a preset counter, timer or
frequency meter
– one or two preset values (selectable)
– relay or optocoupler outputs
– programming of count functions/operating parameters
via the setting keys. During programming the display
guides the user with text prompts.
– programmable features:
operating mode (output signal at zero or at preset
point, with or without automatic reset)
decimal point
polarity of the inputs (NPN or PNP)
input mode and scaling factor
output signals to be permanent or timed
gate time when programmed as a frequency meter
resolution when programmed as a timer (s, min, h or
h:min:s)
– supply voltage 230 VAC, 115 VAC, 48 VAC, 24 VAC or
11...30 VDC
– backlit display (optional)
2. Inputs
2.1 INP A, INP B
Count inputs; max. count frequency 30 Hz or 10 kHz se-
parately selectable for both inputs via programming swit-
ches C and D at the right side of the housing.

2.2 Gate
Static input; no counting while this input is activated. If
operated as a timer (only h, min and 0.1min resolutions),
the decimal point between the 5th and 6th decade flas-
hes while gate input is not activated (operating indica-
tion).
2.3 Reset
Dynamic input; sets the counter to zero (adding mode)
or to preset value 2 (subtracting mode).
2.4 Key
Static keyboard lock input. While this input is activated, it
is neither possible to reset the counter nor to change the
preset values.

4. Outputs
4.1 Output 1
Relay with potentialfree make or break contact or opto-
coupler with open collector and emitter.
4.2 Output 2
Relay with potentialfree change-over contact or opto-
coupler with open collector and emitter.
4.3 Activated outputs
will be indicated by
For safety circuits the operation of the relay, resp. the
optocoupler may be inversed. Thus the relay coil will be
dead, resp. the optocoupler will be locked when reaching
the preset point / zero. For that the output signals Out 1
and Out 2 must be set to – l – (permanent signal) or – l – l –
(timed signal) during the programming routine.
Caution: For all operating modes with automatic repeti-
INP B
tion (AddAr, SubAr, AddbAt, SubbAt) the duration of the
30 Hz 10 kHz
timed signal for output 2 has to be programmed, other-
wise the output signal has no defined duration (see pro-
gramming Out 2).
