Eco-COUNT METER and Eco-HOUR METER are ideal for maintenance
of your facilities and machinery.
FEATURES
1. Easy to install on existing machinery
Just attach the dedicated CT to your existing
cables. There is no need to install any
additional cabling.
2. Built-in battery
The built-in battery allows the units to be
installed anywhere.
3. Economically priced
4. Compact size doesn’t take up space
(DIN 24 x 48)
Easy to install even in cramped spaces.
5. Two installation methods available
(Separate models)
Two installation methods are available: The
extremely easy-to-use one-touch installation,
and the installation frame installation, used for
timers/counters (protective construction IP66).
Select the installation type that suits the
location.
6. Letter’s height is 8.7 mm
A large LCD panel is used, with a highly
legible 8.7 mm letter’s height.
7. Conform to CE marking (EMC directive)

1. Panel installation
1) Installation using plastic magnet
Attach the unit to the equipment case.
2) Installation via double-sided tape
Use this method in places where a plastic
magnet cannot be used or where installation
strength is insufficient.
3) Installation via clamp
Clamp to one of the cables inside the
equipment, etc.
Note: Take careful note of the precautions for use in the catalog or user’s manual before using an Eco-COUNT METER or Eco-HOUR METER installed by one of the methods described above.

EXPLANATION OF OPERATION
KC2S Eco-COUNT METER
1. The number of power-ons is counted by
sending through current through the
dedicated CT.
2. When the number of power ons
(measured value) reaches the full scale,
it reverts to 0, and starts counting again
from 0.
3. When the reset terminal input is set to
on, the display will read “0”. This does not
count during reset input.

1. The power-on time is measured when the
dedicated CT detects a through current.
2. When the elapsed time (number of hours
measured) reaches the full scale, the
display reverts to 0, and starts timing again
from 0.
3. When the reset input is set to on, the
display will read “0”. This does not time
during reset input.

Notes: 1. When using contact input, since current flow is small from reset input terminal
3,
please use relays and switches with high contact reliabillity.
2. When using transistor input, use the following as a guide for which transistors (Tr) to use for inputting.
(Collector withstand voltage950V, leakage current < 1μA)
NOTES
1. Main unit
1) Reset input
(1) Never apply voltage to reset input. This can
cause damage to the internal elements.
(2) Since the current flow is very small from
reset input terminal
3,
please use relays and
switches with high contact reliabillity.
When inputting a reset by a transistor’s open
collector use a transistor for small signals in
which I
CBO
is 1μA or less and always input with
no voltage.
(3) When wiring, try to keep all the input lines
to the reset inputs as short as possible and
avoid running them together with high voltage
and power transmission lines or in a power
conduit.
Note that power cable floating capacitance in
excess of 500 pF (10m on 2 mm

parallel
cables) could cause malfunctions. Take
particular care of inter-cable capacitance
when using shielded cables.

1) Measured power is AC (50 Hz/60 Hz).
Will not function when used with DC power.
2) When clamping to the power cable to be
measured, clamp only one of the live wires.
3) Avoid usage that bends the lead wire.
4) When clamping, make sure that no dust or
other foreign matter intercedes between the
clamp and contact. Foreign matter could
impact detection sensitivity.
3. Insulation sheet
Before using, please pull and remove the
insulation sheet 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 key.

4. Waterproof construction
The operation part 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 sufficient pressure applied to
the rubber gasket to prevent water from
entering.
Be sure to use the mounting screws when
using the mounting frame (ATH3803).
Attaching the one-touch installation type to a
panel will not waterproof the panel surface.
