3 = Three-wire connection (pulse control): Para ID 190: DI changes from open to closed = start pulse Para ID
191: DI changes from closed to open = stop pulse Para ID 198: DI closed contact = reverse/ open contact
= forward - This would be considered 3 wire control with Start Signal 1 being the Start Pulse and Start
Signal 2 being the NC Stop.

Signal selection 1 for the start/stop logic listed in parameter Para ID 143. This parameter would correspond
to the function listed for DIN1. When the parameter is set to DigIN: 1 it references DIN1 on the control
board, selecting different DIGIN values will assign it to a different input on the control board or option card.
When set to Normally Open this function would be always tied low or 0 when using I/O terminal 1 as the
control place. When value is set to Normally Closed this will cause the function to be always on and activate
the output if I/O Terminal 1 is the current control place. Can be set to DigiIN:X indicates on board terminal
inputs, DigiIN:A:IOX:X indicates optional board inputs in A slot, DigiIN:B:IOX:X indicates optional board inputs
in B slot, or Timer Channel X

Signal selection 2 for the start/stop logic listed in parameter Para ID 143. This parameter would correspond
to the function listed for DIN2. When the parameter is set to DigIN: 2 it references DIN2 on the control
board, selecting different DIGIN values will assign it to a different input on the control board or option card.
When set to Normally Open this function would be always tied low or 0 when using I/O terminal 1 as the
control place. When value is set to Normally Closed this will cause the function to be always on and activate
the output if I/O Terminal 1 is the current control place. Can be set to DigiIN:X indicates on board terminal
