Operating Instructions
Electronic Preset Counter
E5148C142 Series
1. Description
– 6 digit preset counter, 1 preset, add./subtr.
– bright 2-line LCD display with symbols for activated
output and current preset value
– count and preset range – 999999 to 999999, over- or
underflow without count loss up to 1 decade (will be
indicated by flashing of the display with 1 Hz
frequency)
– programmable to operate as a preset counter, timer or
frequency meter
– relay or optocoupler output
– 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 230V AC, 115V AC, 48V AC, 24V AC or
11 – 30V DC
– backlit display (optional)
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.
2.2 Gate
Static input; no counting while this input is activated.
If operated as a timer (only h, min and 0.1 min resolu -
tions), the decimal point between the 5th and 6th
decade flashes while gate input is not activated
(operating indication).
2.3 Reset
Dynamic input; switched in parallel with the red set key
and sets the counter to zero (adding mode) or to the
preset value (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 value.
3. Display

symbol for activated output
indicator for current preset value
4. Output
Relay with potential free change-over contact or
optocoupler with open collector and emitter.
Activated output will be indicated by I.
For safety circuits the operation of the relay, or the
optocoupler may be inverted. Thus the relay coil will be
dead, or the optocoupler will be locked when reaching
the preset point. For this application, the output signal
Out 1 must be set to –l– (permanent signal) or
–l–l–
(timed signal) during the programming routine.
Caution: For operating modes with automatic reset
(AddAr, SubAr) the duration of the timed signal for the
output has to be programmed, otherwise the output
signal has no defined duration (see programming).
5. Setting of the operating parameters
a. connect to supply voltage
b. set DIP switch “A” (right side of the housing) to “ON”
for a short time. Display will show 1st menu item
“Mode”.
c. select required function via
key
d. press P-key to store selected function/enter data and
to change over to next menu item.
e. select the desired function again via
key to enter
data (prescaling factor, duration of timed signal, gate
time, resolution) directly via the two arrow-keys.
f.
After programming the last menu item (permanent or
timed signal), the programming routine will be exited
by pressing the P-key, if DIP switch “A” is set to
“OFF”. If it is still set to “ON”, the programming
routine will be passed through once again.
