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.

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

Caution • 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).
