Multifunction Preset Counter

H7CX

I 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.

I 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)

I 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.

I 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.

I 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.

I 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.
