Alarm output
This is set to OFF when an alarm is triggered for even one of the connected counter
boards. It is set to ON in all other cases.
However, note that the display unit alarm output cannot be used when a BCD board is
installed, so use the BCD connector alarm output instead.
Note
When connecting only one channel of the measuring probe to the counter board, set
"display setting" in the initial settings to "Only A". If "A and B" is set, the unconnected
channel will trigger an alarm and the alarm status will result even if all channels of the
connected measuring probe are normal.
Overall start/hold input
This starts/holds all connected measuring probes at once. Refer to the counter board
"start/hold input" item for a description of operation.
Overall reset/recall input
This resets/recalls all connected measuring probes at once. Refer to the counter board
"reset/recall input" item for a description of operation.
