Operating instructions
Electronic LED
Preset Counter
Typ KCT1-5SR-V
1. Description
•
5 digit preset counter, 1 preset point,
add./subtr.
•
bright LED display with 7.5 mm high characters
•
count and preset range –19999 to 99999,
over- or underflow without count loss up to
1 decade (will be indicated by flashing of the
display with 1 Hz frequency)
•
programmable as impulse counter, frequency
meter or timer
•
relay
•
prescaling factor 0.001...9.999
•
programming of count functions/operating
parameters via the preset keys. During pro-
gramming the display guides the user with
text prompts.
•
programmable are:
operating mode (output signal at zero or at
preset point, with or without automatical reset)
decimal point
polarity of the inputs (NPN or PNP)
input mode and factor
output signal to be permanent or timed
gate time when programmed as a frequency
meter
resolution when programmed as a timer
(s, min or h)
supply voltage 230 VAC
•
Auflösung in s, min oder h als Zeitzähler
•
Spannungsversorgung 230 VAC
2. Inputs
2.1 INP A, INP B
Count inputs; max. count frequency 30 Hz or
10 kHz separately selectable for both inputs via
programming switches
C and D at the right side of
the housing.
Microswitch 30 Hz 10 kHz 30 Hz 10 kHz

2.2 Gate
Static input; no counting while this input is acti-
vated. If operated as a timer (only h, min and
0.1 min resolutions), the decimal point between
the 4th and 5th decade flashes while gate input
is not activated (operating indication).
2.3 Reset
Dynamic input; it is connected in parallel to the
red reset key and sets the counter to zero
(adding mode) or to the preset value (subtract-
ing mode).
2.4 Latch
Static input for display stop. If this input is acti-
vated, the current count value will be retained
until the latch input will be released again.
Counting continues in the background.
2.5 Key
Static keyboard lock input.
While this input is activated, all front keys are
locked.
3. Output
Relay with potentialfree change-over contact or
optocoupler with open collector and emitter.
When this output is activated, an annunciator
(decimal point) will appear on the right of the
first decade.
For safety circuits the operation of the relay,
resp. the optocoupler may be inversed in oper-
ating modes 1 and 2 (permanent signal only ) by
programming 99.99 for duration of output signal
. Thus the relay coil will be dead, resp. the opto-
coupler will be locked when reaching the preset
point/zero.
4. Programming procedure
a. connect to supply voltage
b. set microswitch "A" (right side of the housing)
Menüpunkt weitergeschaltet.
c. select required functions via preset key 1,
resp. enter data (prescaling factor, duration of
timed signal, gate time) directly via preset keys
1–4.
