Multifunction Preset Counter
H7CX
■
Self-diagnostic Function
The following displays will appear if an error occurs.
Note: 1.
The display for 4-digit models is given in parentheses.
2.
Display flashes (1-second cycles).
3.
Occurs when the present value or the total count value goes below
−
99,999 (
−
999 with 4-digit models).
4.
Occurs when the present value (or measurement value) reaches 999,999 (9,999 with 4-digit models) under the following conditions:
•
The output mode is K-2, D, L, or H.
•
The H7CX is set for dual counter or tachometer operation.
5.
Except when the H7CX is set for tachometer operation.
6.
Includes the case where the EEPROM has reached its overwrite lifetime.

Response Delay Time When
Resetting (Transistor Output)
The following table shows the delay from when the reset signal is
input until the output is turned OFF.
(Reference values)
■
Output Delay Time
The following table shows the delay from when the present value
passes the set value until the output is produced.
Actual measurements in N and K-2 modes.
(Reference values)
Note:
The above times may vary slightly depending on the mode or
operating conditions.
■
Maximum Counting Speed for
Batch Counter
The maximum counting speed for batch counter operation is 5 kHz.
The batch counter counts the number of times the count reaches the
set value.
■
Wiring
Wiring input lines in the same conduit as power lines or other high-
voltage lines may result in malfunction due to noise. Wire the input
lines separately, away from lines carrying high-voltages. In addition,
make the input wiring as short as possible and use shield lines or
metal wiring conduits.
Pay attention to terminal polarity to ensure correct wiring.
■
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 H7CX’s panel surface is water-resistive (conforming to NEMA 4
and IP66). In order to prevent the internal circuit from water penetra-
tion through the space between the timer and operating panel, attach
a waterproof packing between the timer and installation panel and
secure the waterproof packing with the Y92F-30 Flush-mounting
Adapter.
