■ Key Protect Level
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by
specifying the key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/
OFF status of the key protect switch after the H7BX is mounted to the panel.
Note: Changing to configuration selection mode and function selection mode.
■ Self-diagnostic Function
The following displays will appear if an error occurs.
Note 1. Display flashes (1-second cycles).
2. Occurs when the present value or the total count value goes below −99,999
3. Occurs when the present value reaches 999,999 under the following conditions:
• The output mode is K-2, D, L, or H.
• The H7BX is set for dual counter operation.
4. Except when the H7BX is used as a tachometer.
