Precautions
!Caution
Do not use the product in locations subject to flammable or explosive gases. Doing so may result in explosion.
!Caution
The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may result in
contact deposition or burning.
!Caution
Do not disassemble, repair, or modify the product. Doing so may
result in electric shock, fire, or malfunction.
!Caution
Do not allow metal objects or conductive wires to enter the product. Doing so may result in electric shock, fire, or malfunction.
Other Precautions
• Store at the specified temperature. If the H8GN has been stored at
a temperature of less than −10°C, allow the H8GN to stand at room
temperature for at least 3 hours before use.
• Use the product within the ratings specified for vibration, shock,
submerging in water, and exposure to oil.
• Do not use the product in locations subject to dust, corrosive
gases, or direct sunlight.
• Use the product within the ratings specified for temperature and
humidity.
• The product is designed for 24 VDC. Applying voltages other than
the rated one such as 100 to 240 VAC may damage the internal
elements.
• Separate the input signal devices, input signal cables, and the
product from the source of noise or high-tension cables producing
noise.
• Separate the product from the source of static electricity when
using the product in an environment where a large amount of static
electricity is produced (e.g., forming compounds, powders, or fluid
materials being transported by pipe).
• Do not expose the product to organic solvent such as thinner or
benzine, strong alkali materials, or strong acid materials. Doing so
may damage the product surface.
Application Precautions
1. Do not use the product in locations where condensation may
occur due to high humidity or where temperature changes are
severe.
2. Be sure to wire terminals correctly, with the correct polarity.
3. Maintain the power supply voltage within the allowable ranges.
4. Connect the power supply through a relay or switch so that the
voltage reaches a fixed value immediately. If the voltage
increases gradually the power supply may be reset or outputs
may turn ON.
5. When the power is turned ON, an inrush current (approx. 15 A)
will flow momentarily. Depending on power supply capacities, the
product may not start due to this leakage current. The power supply must be of a sufficiently large capacity.
6. For the main power supply or the power supply for input devices,
use a power supply transformer whose primary side is insulated
from the secondary side and whose secondary side is not
grounded.
C-68
Preset Counter/Timer H8GN
7. Leaving the H8GN with outputs ON at a high temperature for a
long time may hasten the degradation of internal parts (such as
electrolytic capacitors). Therefore, use the product in combination
with relays and avoid leaving the product as long as more than 1
month with the output turned ON.
Power Supplies
When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below.
Power
supply
ON
OFF
Input
210 ms 0 to 50 ms
Impossible
5 ms
Possible
0 to 500 ms
Unstable Impossible
Unstable
Turn the power ON and OFF using a relay with a rated capacity of
15 A minimum to prevent contact deterioration due to inrush current
caused by turning the power ON and OFF.
When power is turned ON, a starting current flows momentarily.
Therefore, pay attention to the overcurrent detection level of the
power supply used.
Timer Control with Power Start
To allow for the startup time of peripheral devices (sensors, etc.), the
H8GN starts timing operation between 210 to 260 ms after power is
turned ON (see diagram above). For this reason, in operations where
timing starts from power ON, the time display will actually start from
258 ms. If the set value is 258 ms or less, the time until output turns
ON will be a fixed value between 210 and 260. (Normal operation is
possible for set value of 259 ms or more.) In applications where a set
value of 258 ms or less is required, use start timing with signal input.
When the H8GN is used with power start in F mode (i.e., accumulative operation with output on hold), there will be a timer error (approximately 100 ms each time the H8GN is turned ON) due to the
characteristics of the internal circuitry. Use the H8GN with signal
start if timer accuracy is required.
Changing the Set Value
In Counter Operation
When changing the set value during operation, the output will turn
ON if the set value equals the present value.
In Timer Operation
When changing the set value during operation, if the set value is
changed in so that the conditions below are satisfied, the Timer operates in the same way as when the present value reaches the set
value because a constant read-in system is in use. Depending on the
output mode, this may result in output turning ON.
Timer mode UP:
Present value ≥ set value
Timer mode DOWN:Elapsed time ≥ set value
(Present value = 0)
Note: When in DOWN mode, the amount set value is changed is added to or subtracted from the present value.
Operation with a Set value of 0
Output
In Counter Operation
The SPDT (single-pole, double-throw) consists of an SPST-NO contact and an SPST-NC contact. Do not form a circuit with 3-point
short-circuit (power short-circuiting with arc).
The output will turn ON if the set value (0) equals the present value.
The output will be OFF while the Reset Key is pressed or the reset
input is ON.
a) When the output mode is set to A, B (one-shot output), D, or F,
output will turn ON when the start signal is input.

Waterproof packing
Panel
The H8GN’s panel surface is water-resistive (conforming to NEMA
4X (indoors) and IP66). In order to prevent the internal circuit from
water penetration through the space between the Counter and operating panel, attach a rubber packing (provided with the H8GN)
between the Counter and operating panel and secure the rubber
packing with the Y92F-34 Flush-mounting Adaptor.
