GPI Menu
The GPI menu screen shown on the following page allows configuration of the two external GPI
inputs. The two Override GPI inputs will force the switch to either Primary or Secondary when closed
to ground. The GPI inputs are edge-triggered on a negative pulse, or simply a falling edge. These
inputs may also be used to switch back to the Primary after a fault has cleared.
The Primary GPI Mode can be set to one of the following:
• Off – disables the Primary GPI input, located on pin 7 of the 9 pin female D connector.
• Neg Edge Switch – tells the processor to force to the Primary if ground is input into pin 7 of
the 9 pin female D connector (switches on a low-going transition to the GPI input).
• Neg Edge Reg 1 – tells the processor to switch to the Memory Register 1 presets if ground is
input into pin 7 of the 9 pin female D connector (switches on a low-going transition to the
GPI input).
The Secondary GPI Mode can be set to one of the following:
• Off – disables the Secondary GPI input, located on pin 8 of the 9 pin female D connector.
• Neg Edge Switch – tells the processor to force to the Secondary if ground is input into pin 8 of
the 9 pin female D connector (switches on a low-going transition to the GPI input).
• Neg Edge Reg 1 – tells the processor to switch to the Memory Register 1 presets if ground is
input into pin 8 of the 9 pin female D connector (switches on a low-going transition to the
GPI input).

• GPI is Low
• GPI is High
The Sec GPI Status report window indicates the GPI status as either:
