How to set
1. Preset value setting mode
This is the mode for setting preset values.
1) Pressing the MODE key takes you to
the preset value setting mode.
2) Pressing the setting key moves the
flashing digit left by one. Following the
highest digit it returns to the lowest digit
and each time the digit setting key is
pressed it moves one to the left.
3) Pressing the set key increases the
value by one. (After 9 it returns to 0 and
then changes to 1, 2, 3, etc.)
4) Pressing the front panel reset key sets
the displayed preset value and returns
you to the regular operation mode.
5) In the preset value setting mode if you
do not operate the digit setting key or the
set key for ten seconds or more you will be
returned to regular operation. In this case
the preset value will not change.
2. Lock mode
This mode prohibits everything except the
preset value setting mode.
1) Pressing the set key while holding
down the mode key takes you to the lock
mode.
2) The display reads “Un-Lock”after
entering the lock mode (initial setting).
3) Pressing the setting key changes the
display between “Lock”and “Un-
lock”.
4) Pressing the front panel reset key sets
the content displayed and returns you to
regular operation mode.
Note: You will not be returned to regular operation
mode if you do not press the front panel reset
key.
5) When the lock mode display reads
“Lock”, you will not be able to move
to the backlight setting mode, the input
setting mode, or the output setting mode.
3. Backlight setting mode
This is the mode for setting the backlight
during count up.
1) Pressing the SET key two times while
holding down the MODE key takes you to
the backlight setting mode.
2) The display in the backlight setting
mode reads “LEd”
3) The LED backlight will be red (initial
setting).
23/
4) The backlight changes from flashing
green to flashing red to lit green and to lit
red with each press of the setting key.
5) Pressing the front panel reset key sets
the current backlight color and returns you
to regular operation mode.
Note: You will not be returned to regular operation
mode if you do not press the front panel reset
key.
Press the MODE key. Set the digit. Set the value.

4. Input setting mode
This is the mode for setting addition or
subtraction.
1) Pressing the SET key three times while
holding down the MODE key takes you to
the input setting mode.
2) The display after entering the input
setting mode reads “UP”(initial
setting).
3) Pressing the setting key changes the
display to “dn”(subtraction) and pressing
it again changes it to “UP”(addition). The
display alternates between “dn”and “UP”.
4) Pressing the front panel reset key sets
the content displayed and returns you to
regular operation mode.
Note: You will not be returned to regular operation
mode if you do not press the front panel reset
key.

Changing the preset value
1. It is possible to change the preset
value even during counting. However,
be aware of the following points.
1) If the preset value is changed to less
than the count value with counting set to
the addition direction, counting will
continue until it reaches full scale, returns
to zero, and then reaches the new preset
value. If the preset value is changed to a
value above the count value, counting will
continue until the count value reaches the
new preset value.
2) Suppose that the counter is preset to
count down.Whether a preset count down
value is smaller or larger than the count
value, the counter counts down to “0
(zero)”.
2. If the preset value is changed to “0”,
the counter will not complete count-
up. It starts counting up when the
counting value comes to “0 (zero)”
again.
1) Addition (up-count) input when
counting is set to the addition direction,
counting will continue until full scale is
reached, return to zero, and then
complete count-up.
2) Subtraction (down-count) input when
counting is set to the subtraction direction,
counting will continue until full scale
“–9999999”is reached, and then the
display will change to “”.

Output maintain/
hold count
Output control is maintained after count-up
completion and until resetting.
During that time, the count display does not
change from that at count-up completion.
Output maintain/
over count I
Output control is maintained after count-up
completion and until resetting. However,
counting is possible despite completion of
count-up.
One shot/
over count
Output control is maintained after count-up
completion for a fixed time (approx. 1 sec.).
Counting is possible despite completion of
count-up.
One shot/
recount I
Output control is maintained after count-up
completion for a fixed time (approx. 1 sec.).
Counting is possible despite completion of
count-up. However, reset occurs
simultaneous with completion of count-up.
While output is being maintained, restarting
of the count is not possible.

Cautions for use
1. Input and output connection
1) Input connection
(1) Contact input
Use highly reliable metal plated contacts.
Since the contact’s bounce time leads
directly to error in the count value, use
contacts with as short a bounce time as
possible. In general, select input to have a
maximum counting speed of 30 Hz.
(2) Non-contact input (Transistor input)
Connect with an open collector. Use
transistors whose characteristics satisfy
the criteria given below.
VCEO = Min. 20 V
IC = Min. 20 mA
ICBO = Max. 6 µA
Also, use transistors with a residual
voltage of less than 2 V when the
transistor is on.
* The short-circuit impedance should be less
than 1 kΩ.
(When the impedance is 0 Ω, the current
coming from the count input terminal is
approximately 5 mA and from the reset
input terminal is approximately 1.5 mA.)
Also, the open-circuit impedance should
be more than 100 kΩ.
(3) Input wiring
When wiring, use shielded wires or
metallic wire tubes, and keep the wire
lengths as short as possible.
2) Output connection
Since the transistor output of counter is
insulated from the internal circuitry by a
photo-coupler, it can be used as an NPN
output or PNP (equal value) output.

3. Terminal connection
1) When wiring the terminals, refer to the terminal layout and
wiring diagrams and be sure to perform the wiring properly
without errors.
2) After turning the counter off, make sure that any resulting
induced voltage or residual voltage is not applied to power supply
terminals (1) through (2). (If the power supply wire is wired
parallel to the high voltage wire or power wire, an induced voltage
may be generated at the power supply terminal.)
3) Have the power supply voltage pass through a switch or relay
so that it is applied at one time.

PRECAUTIONS IN USINGTHE LC2H SERIES
CAUTIONS FOR USE
1. Insulation sheet
Before using a panel mounting type,
please pull and remove the insulation
sheet from the side of the product in the
direction of the arrow.
In consideration that the product might be
stored for long periods without being
used, an insulation sheet is inserted
before shipping. Remove the insulation
sheet and press the front reset button.
•LC2H total counter (one-touch
installation type)
•LC2H total counter (installation frame
type)
2.Waterproof construction
•LC2H total counter (installation frame
type)
The operation part of the panel
installation type (installation frame type) is
constructed to prevent water from
entering the unit and a rubber gasket is
provided to prevent water from entering
the gap between the unit and the panel
cutout.
There must be suf ficient pressure applied
to the rubber gasket to prevent water from
entering.
Be sure to use the mounting
reinforcement screws when installing the
mounting frame (ATH3803).
Note:The one-touch installation type is
not waterproof.
•LC2H preset counter
1) The front plate will not be waterproof
when this product is installed on a panel.
To make the front plate waterproof, please
install the following.
When using the waterproof type (IP66:
panel front only), install the counter to the
front plate with mounting frame ATH3803
(sold separately) and rubber gasket
ATH3804 (sold separately). Be sure to
tighten using mounting screws.
2) Panel installation order
(1) Remove o-ring.
(2) Place rubber gasket.
(3) Insert counter into panel.
(4) Insert mounting frame from the
rear.
(5) Secure with mounting screws (two
locations)
3. Do not use in the following
environments
1) In places where the temperature
changes drastically.
2) In places where humidity is high and
there is the possibility of dew.
(When dew forms the display may vanish
and other display errors may occur.)
4. Conditions of use
1) Do not use on places where there is
flammable or corrosive gas, lots of dust,
presence of oil, or where the unit might be
subject to strong vibrations or shocks.
2) Since the cover is made of
polycarbonate resin, do not use in places
where the unit might come into contact
with or be exposed to environments that
contain organic solvents such as methyl
alcohol, benzene and thinner, or strong
alkali substances such as ammonia and
caustic soda.
