This is a commonly requested External Switch Combination used on the PS220
Refer to the diagram below.
Functionality:
“Auto Control” from two external locations.
External Location 1:
DI1 is assigned to “Auto”
External Location 2:
DI5 is assigned to “Auto”.
This combination requires a pre-assigned switch
using Digital Input 3 (DI3) to switch between these
2 Auto Choices. DI3 High selects Auto DI1, DI3 Low
selects Auto DI5.
DI2 is assigned to Hand or “Speed Override”
All switches are normally open
The table below lists all the choices that can be configured for the start and stop method on the PS220. The Digital Inputs
