EXT2: 2-Wire switch at DI5.
This requires a preassigned switch (DI3) to switch between these choices.
All switches are “normally open”
FIELDBUS Start via Fieldbus control word. External control location 1 only.
DI1P,2P – FB
Control at two external locations. EXT1: 3-Wire pulse start assigned to DI1 and pulse stop
