Notes : 1. Eight relay contacts are outputed from interface terminal (ALM TERMINAL). Plural alarms
can be applied to a single relay. The figure shows the default settings. Refer to paragraph 3.4
for changing the settings.
2. Refer to the table 3.2 for Interface Terminals and Jacks for the details of pin assignment for
the alarm signals.
