GPI Output Function
The GPI Output Function submenu is used to determine the GPO Polarity and GPO
Output Setup for each input.
GPO Out 1 and 2 Polarity
There are two OUTPUT GPIs that are associated with a list of alarms. All GPI alarm
activation selections are set to the default OFF until the alarm is enabled. When an
alarm is enabled, the GPI functions according to the GPO OUT 1 and 2 POLARITY
setting (NORMALLY OPEN, NORMALLY CLOSED). The default polarity is
NORMALLY OPEN.
• NORMALLY OPEN: The contact closure on the GPI board is normally open.
When the contact closure closes, the GPO alarm is activated.
• NORMALLY CLOSED: The contact closure on the GPI board is normally
closed. When the contact closure opens, the GPO is activated.
GPO Out 1 and 2 Setup
The GPO Out 1 and 2 Setup submenu is used to select what input or alarm the GPO
follows. If an alarm occurs on an input associated with the GPO, the GPO will change
its polarity setting. If Follow Alarms is selected, the GPO will change its polarity
setting whenever an alarm occurs on any input.
