• Counting the CP1 input cannot be performed while the reset 1 input is ON.

• The reset indicator is lit while the reset 1 input is ON.

The reset operation depends on the selected function. (See note 3.)

When the corresponding set value is reached, signals are output according to the
designated output mode.

• Resets the total count value.

• Holds the total count value at 0 while the total reset input is ON.

Note: Depending on the operating environment,

the condition of resin parts may
deteriorate, and may shrink or harden.
Therefore, it is recommended that resin
parts are replaced regularly.

Product Protection for Use in
Environments Subject to Water or Oil

The panel surface has a protective
structure so that the internal circuits will
not be adversely affected if drops of water
penetrate the gaps between the keys. If,
however, there is a possibility of water or
oil being present on the operator's hands,
mount the optional Soft Cover.
The Soft Cover ensures protection
equivalent to IP54. Do not, however, use
the H7BX in locations where it would come
into direct contact with oil.

Caution

• Always turn OFF the power supply before changing the DIP switch settings.

• Always turn ON pin 1 when performing settings with the DIP switch. Performing settings with the DIP switch is

disabled when pin 1 is OFF.

• DIP switch setting changes will be updated when the power is turned ON. Perform the settings before performing
installation and supplying power.

• Properly set the DIP switch to match the item being counted (or measured) and use the DIP switch monitor for
confirmation.

• Use the keys on the front panel to perform all settings for input modes, output modes, and output times that cannot
be set with the DIP switch. For details on the setting methods, refer to page 10.
When performing these settings, always turn OFF pin 1(DIP switch setting) (disabled).
