Precautions
!
WARNING
BEFORE USE
This product has a built-in lithium battery. Do not short-circuit
the+and -- terminals, charge, disassemble, deform, orexpose
the battery to fire. The battery may explode (break), catch fire,
or cause liquid leakage.
An insulation sheet has been inserted to maintain the quality of
the Totalizer in the event of a long period without use. Be sure to
remove this sheet before attempting to use the product.
Remove the insulation sheet and press the Reset Key on the
front panel of the Counter. (With the H7ER-N,-NV(-H),-NV1(-H),
models, “0” or “0.0” will be displayed after 1 s.)
!
Caution
Donot useany battery otherthanthespecifiedone(Y92S-36).
Using another battery may cause liquid leakage or breakage,
resulting in malfunction or injury.
lation Sheet
!
Caution
If a voltage other than the rated one is applied, internal
elements may be damaged.
Reset Key
Do not use the Counter in the following places:
•
•
•
Locations subject to direct sunlight.
Locations subject to corrosive gases.
Locations subject to dust.
Switch settings on the Counter must be performed before
mounting it to a control panel.
Do not use the Counter in locations subject to:
Severe changes in temperature.
Condensation as the result of high temperatures.
MOUNTING PRECAUTIONS FOR FLUSH
MOUNTING
Although the operating section is watertight (conforming to
NEMA4, IP66), rubber packing is provided to avoid water leakage
through the gap between the Counter and panel cutout. Unless
this rubber packing is tightly squeezed on, water may permeate
inside the panel. For this reason, be sure to tighten the screws
for fixing the Flush Mounting Bracket.
Screw for the Flush Mounting Bracket
The wider side must
face the panel.

RESET INPUT AND COUNT INPUT
COUNT INPUT OR RESET INPUT TO
MORE THAN ONE H7ER COUNTER AT
A TIME
The H7ER operates using its built-in Battery. If the H7ER is
connected to a device that has +V and OUT terminals connected
with a diode as shown in the circuit diagram, the circuit indicated
by the arrow 1 or 2 will be formed when the device is turned OFF.
As a result, the H7ER may be reset or count by one. Such
devices should not be connected to the H7ER.
PNP/NPN Universal DC Voltage Input

or
If an excessive voltage is applied to the count or reset input
terminals, the internal elements may be damaged.
Ensure that the following voltages are not exceeded:
PNP/NPN universal voltage input model: 30 VDC

At reset input:
3 VDC (no-voltage input)
No-voltage input model: 3 VDC
No-voltage Input
Do not remove the outer case when voltage is being applied to
the power supply terminals or to the input terminals.
or
The input for the H7E -NFV- is a high-impedance circuit so
influence from an induced voltage may result in malfunction.
When the input signal wiring is longer than 10 m (stray
capacitance of 120 pF/m, at room temperature), a CR filter or a
bleeder resistor should be connected.
Note: 1. The leakage current of the transistor used for input
must be less than 1 µA.
2. The forward voltage of the diode must be as low as
possible (i.e., 0.1 V maximum with an I of 20 µA) so
F
the voltage between terminals 3 and 4 will be 0.5 V
when the reset input is ON.

INPUT AND POWER SUPPLY
BATTERY REPLACEMENT
Do not apply voltage on the Counter if the Counter is a model
that operates with no-voltage input, or the internal circuit of the
Counter may be damaged.
Remove the wiring when replacing the Battery. Do not come in
contact with any item to which high voltage is being applied.
Doing so may result in electric shock.
Do not connect any single input signal in parallel to Counter
models operating with no-voltage input and those operating with
voltage input, to avoid malfunction.
Before changing the Battery, be sure that you are not carrying
any static electric charge.
Procedure for replacing the Battery (refer to the diagrams below):
When connecting a sensor to the Counter that operates with
no-voltage input, make sure that the sensor has open collector
output.
1. Using the tool, pry open the lift-tab on the case. (1)
2. Pull the body out of its outer case. (2)
3. Lift the Battery up by the edge and remove it. (3)
When removing the Battery, do not come in contact with the
display area or any internal parts.
Sensor
4. Wipe the back of the new Battery before inserting it.
5. Ensure that the + and -- terminals are correctly oriented.
6. After replacing the Battery, re-insert the body into its case. (4)
Check that the case is securely held in by the lift-tab.
7. Press the Reset Key before use (not necessary for
H7ER-N,-NV,-NV1). (5)
The operation of the Counter may be affected if the line voltage
of the power supply exceeds 500 pF (about 10 m, with parallel
wires of 2 x 2 mm). Keep all wires as short as possible. When
using shielded wire, stray capacitance may occur.
When the internal Battery nears expiration, the display may
flicker.
When connecting an open collector input from a transistor to the
Counter that operates with no-voltage input, make sure that the
leakage current of the transistor is 5 µA maximum.
(2)
(1)
Tool
When connecting count input from an SSR to the Counter that
operates with AC/DC voltage input, use OMRON’s G3TA-IA or
G3TA-ID SSR. Make sure that the leakage current of the SSR is
0.1 mA maximum or connect a bleeder resistor in parallel to the
input circuit of the Counter.
(1)
(3)
or
Leakage current:
0.1 mA max.
or
(4)
or
*Bleeder resistor
The voltage between terminals 1 and 2 must be
1.5 V maximum when the SSR is OFF.
(5)
BACKLIGHT POWER SUPPLY
EN/IEC STANDARDS
To reduce variation in the brightness of the backlight when using
more than one H7ER with a backlight, use the same power
supply for all the backlights.
The counter input, reset input, and backlight power supply
terminals of the no-voltage input or PNP/NPN universal DC
voltage input models (H7E -N,-N1, H7E -NV(-H),-NV1(-H)) are
not isolated.
A SELV power supply conforming to Appendix H of IEC61010-1
should be used for the counter input, reset input and backlight
power supply terminals. A SELV power supply is a power supply
for which the input and output have double or reinforced
insulation, and for which the output voltage is 30 Vrems with 42.4
V peak or 60 VDC max. (Only the H7E -NV -H has a
backlight.)
When connecting the DC power supply for the backlights, be
sure to connect the polarities correctly.
UNIT LABEL FOR TIME COUNTER AND
TACHOMETER
A unit label has been packed with the Counter. Use in accordance
with the application.
The terminals for counter input and reset input for AC/DC
multi-voltage input models have basic insulation.
Connect the reset input terminals to a device that does not have
exposed current-carrying parts and has basic insulation for
240 VAC.
