Each relay turns on only while the corresponding switch is pressed. When several
switches are pressed simultaneously, one of the relays for the switches turns on.
•
When a contact comment is set to a relay, the comment is displayed (up to 17
characters). When no contact comment is set, the device number is displayed.

Refer to "Displaying contact comment" on page 29.

The customized switches can be used in all modes.
Note 1: The speed required to capture the ON/OFF status of the customized
switches depends on the scan time, communication time, and internal processing
time. If the switches are operated at a speed faster than the capture speed, the KV
unit does not recognize the operation properly.
Note 2: If the modular cable is disconnected while a customized switch is pressed,
the relay corresponding to the switch remains on.
