JC Series Electric Counter –User Manual
General Description
JC series electronic counter provides excellent performance by
using the single chip micro-processor with high accuracy, wide
counting range, digital display, soft contact operating key, data
protection during blackout, strong anti-disturbance capability,
modern design of appearance, etc.
JC series electronic counter can be used in many industrial
applications such as packaging, printing, pharmacy, food, textile,
papermaking, ceramic, petroleum, chemical engineering, metallurgy,
etc. It can also display and control other parameters like rotating
revolution and length.

NOTE: JC □ S- A Model –12VDC wiring terminal is illustrated in the diagram, when external 12VDC power supply is connected from “+12V”
and “COM” terminals (different from other power supply types), the wiring should refer to the diagram shown in bottom right. When use other
types of power supply, they should be connected only from “power supply” terminal, and “+12V” terminal (internal 12VDC power output) is for
sensors only (no external power supply is allowed to connect to the “+12V” terminal, otherwise the counter might be damaged).
Instruction:
1. How to set the preset value:
In the counter mode: press the “preset/parameter” key for ＜3
seconds to enter the preset counter mode and the preset indicator
“SET” will be on. At this stage, the single digit will flush, then press
“ ”key to select the desired digit until it flashes, then press “▲”
key to choose any number from 0→9for the flashing digit. The
valid range for preset value is 0～999999 (note: the valid range for
JC48S is 0～99999). After the preset value is set and verified, press
the “preset/parameter” ＜3 seconds, the counter will automatically
exit the preset mode and enter the counting mode, and the preset
indicator will be off. The counter will remain in the existing settings
if the preset value is not modified. New parameters will be applied
immediately after the preset value is modified.
Note: For JC20S and JC24S, the "▲" key and the "clear" key are
identical，under the counting mode ,the key of“▲/clear” is used
to reset to zero，under the preset mode or parameter setting mode,
“▲/clear” is used to change the preset value or values of
parameters，it dose NOT function as clear key.
2.How to set the counting parameter：
JC series have six function parameters to choose including
software lock , counting frequency , increase/decrease
counting mode , power failure protection on/off , output
control , output time mono-stable delay . Press the
“preset/parameter”key more than 3s to enter the setting mode, the
parameter indicator “PA”will be on. The screen will display
software lock key . Press “preset/parameter”key for less than 3
seconds to choose the different function to modify according to
the following order:

Please refer to Table 2 for the more detailed instruction on how to
set and modify the function parameter.

Additional Information
1. Please wiring according to terminals wiring diagram on the meter
case strictly and ensure the actual power supply is consistent with
the rating value.
2. The connection of sensor and counter must be robust. The signal
lines shall not be placed parallel with the power lines of electric
supply and control lines.
3 please select the sensor reasonably according to requirement and
wiring correctly.
(1) For NPN kind sensor (negative pulse input) or contact counting
signal, the wiring method is shown as Figure 1.
(2) For PNP kind sensor (positive pulse input), the wiring method
is shown as following

5. For contact sensors, please select low speed (0 –25Hz) frequency
6. After power is connected, by selecting the required counting
frequency, the counter will enter the normal counting mode.
