Auxiliary Output
Opening or Closing in
Alarm (sb1n, sb2n)
• When “close in alarm” is set, the status of the auxiliary output is output
unchanged. When “open in alarm” is set, the status of the auxiliary output
function is reversed before being output.
• Each auxiliary output can be set independently.
• These settings are made in the Auxiliary Output 1 to 3 Open in Alarm
parameters (advanced function setting level).
• The default is n-o: Close in Alarm.
• When “open in alarm” is set for the alarm 1 output, the open in alarm sta-
tus is also applied to heater burnout, HS alarm, heater overcurrent, and
input error outputs.
• The alarm output will turn OFF (i.e., the relay contacts will open) when
power is interrupted and for about two seconds after the power is turned
ON regardless of the setting of the Auxiliary Output 1 to 3 Open in Alarm
parameter.
