8.1 OVERVIEW

Alarm settings page sets the condition that will cause an alarm by the PLC. Each button will open a secondary screen
with options for each alarm. Each alarm can either be enabled or disabled. By default, every alarm is disabled, and
editable fields are set to zero.

Note:

Channel 1 and Channel 2 screens contain identical fields and options except where noted.
