Description

A

Cycle On/Cycle On Enable

This is a dual-purpose input.

Clear Outputs

When Set Defaults is clicked, VS sets this input to Start, this input

(Black wire - internal)

functions as a cycle on input. This means a fastening cycle can be

(Black wire - external)

started by either pressing the throttle/trigger switch on the nutrunner OR

by activating this input.

When remote mode for the spindle is set to enable, this input functions

as a cycle on enable input. This means a fastening cycle can be started

only by pressing both the throttle/trigger switch on the nutrunner and

activating this input.

In addition, it is also set to Clear Outputs.

This is a level-sensitive input. For the fastening cycle to proceed, this

input must remain active. If this input becomes inactive at any time

during the fastening cycle, the cycle will be aborted and the nutrunner

will stop running.

B

Forward/Reverse input

When Set Defaults is clicked, VS sets this input to the direction the

(White wire internal)

nutrunner turns in a fastening cycle:

(White wire - external)

If this input is active when a fastening cycle is started, the nutrunner will

run in the forward (fastening or tightening) direction. If this input is

inactive when a fastening cycle is started, the nutrunner will run in the

reverse (un-fastening or loosening) direction.

After a fastening cycle has started, changing the state of this input has

no effect on the fastening direction until the cycle on command (from

either the nutrunner or the cycle on input or both) is de-activated. This

means the input must be in the desired state BEFORE activation of the

cycle start input.

C

Discrete Input #7

Defaults to “Manual Calibration.”

(Gray wire - internal)

(Red wire - external)

D

Discrete Input #8

Multi-purpose switch input “OR” function with switch on tool.

(Yellow wire - internal)

(Green wire - external)
