Tau Controller
Inputs
Description
JOB SELECT
When asserted or removed, the controller selects a Job. This is one bit of a binary number
BIT
created by this bit and operates in the Binary + 1 mode.
Configuration: None
REVERSE
When asserted, the controller will place the tool in Reverse (Disassembly) mode. This will
NOT run the tool in Reverse; it simply changes the tool mode from Forward to Reverse.
When removed the controller will place the tool into Forward (Assembly) mode.
The size of this input function is 1 bit.
Configuration: None
4.2.2 Output Descriptions
Each of the four output elements has two contact types, each with their own dedicated pin. Wire
the plant connection to the appropriate contact type pin to match the specific plant integration
scheme.
Contact Type
The Contact Type can be Normally Open (N.O.) or Normally Closed (N.C.).
Output Type
The Output Type defines the behavior of the output signal.
Normal – The output asserts and stays asserted until a reset condition occurs.
Minimum On Time – Keeps the output asserted for this minimum time, in seconds, even
though a reset condition occurs. After the timer is finished the output will reset if a reset
condition has occurred otherwise it will remain asserted until a reset condition occurs.
Timed – The output asserts for this period of time then resets on its own without waiting for the
reset condition to occur.
Time – Units are in seconds.
Sourcing Outputs (PNP type)
If Pin-15 is wired to Pin-16 to supply the outputs, and an output is asserted, the Normally Open
output pin will transition from 0VDC to 24VDC. The return from the load must be wired to
Pin-1.
Sinking Outputs (NPN type)
If Pin-1 is wired to Pin-16 to supply the outputs, and an output is asserted, the Normally Open
output pin will transition from 24VDC to 0VDC. The return from the load must be wired to
Pin-15.
Outputs
Description
IN CYCLE
This output asserts when the tool torque level, during the tightening cycle, exceeds the
Threshold Torque value. It resets when the tool is shutoff either by reaching target, a
fault, a Stop input, a Start input removed or by the operator. The size of this output
function is 1 bit.
Configuration:
Contact Type
CYCLE OK
Asserts when a tightening cycle that exceeds the Threshold Torque is completed and the
achieved torque and angle are audited within the limits of the audit step. Resets when the
tool exceeds Threshold Torque on the next tightening cycle. The size of this output
function is 1 bit.
Configuration:
