Conditions of Use
Alarms must be assigned as outputs. For
example, if alarm outputs 1 and 2 only are
assigned as outputs, the “alarm 3 open in
alarm” parameter cannot be used.
• Selects the output states of alarms 1 to 3.
• When the controller is set to “close in alarm,” the status of the alarm output func-
tion is output as it is. When set to “open in alarm,” the status of the alarm output
function is output inverted. The following table shows the relationship between
alarm output functions, output and output LEDs.
