Operation with a Set value of 0
In Counter Operation
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.
In Timer Operation
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.
b) When the output mode is set to B (hold output), E, or Z, output will
remain OFF even when the start signal is input.
Response Delay Time When Resetting
The following table shows the delay from when the reset signal is
input until the output is turned OFF.

Output Delay Time
The following table shows the delay from when the timer value
passes the set value until the output is produced.

*The variation in delays is due to different modes and conditions.
Mounting
Tighten the two mounting screws on the Adaptor. Tighten them alter-
nately, a little at a time, so as to keep them at an equal tightness.
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 oper-
ating 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.

Output
The SPDT (single-pole, double-throw) consists of an SPST-NO con-
tact and an SPST-NC contact. Do not form a circuit with 3-point
short-circuit (power short-circuiting with arc).
