Sequence Select Input (Normally Open)
These 3 inputs form a binary code which is capable of selecting up to 8
different operation sequences. The different sequence options allow
the System to fasten to different specifications with only one Main
Controller Unit. Refer to Section 4.7.2 Sequence Select Table. SEQ SELECT 0
SEQ SELECT 1
SEQ SELECT 2 9

Cycle Count Input (Normally Open)
The System cycle counter will increment each time this signal is input if
the CYCLE COUNT UP is set to PLC SIGNAL on the Machine
Configuration screen. The Cycle Count input requires a pulse of at
least 50 milliseconds to increment the counter. If the CYCLE COUNT
UP is set to AUTO, the cycle counter increments automatically at every
fastening. CYCLE COUNT 8
Offset Check Input (Normally Open)
Used to perform the Offset (prevailing torque) Check. The Offset
Check input requires a pulse of at least 50 milliseconds to initiate a
360-degree prevailing torque check. The Busy signal will activate and
the Ready signal will deactivate during the Offset Check process. After
the value has been checked and is verified to be within limits (less than
12% of the tool's full scale torque value), the Accept light on the Main
Unit will illuminate. If the value is outside of the limits, the Reject light
will illuminate and an Abnormal signal will be output to the affected Axis
Unit(s). If the Fastening Sequence OFFSET CORRECTION (OC)
command is enabled, the data from the Offset Check will be used to
compensate for the prevailing (offset) torque. If the Fastening
Sequence OFFSET CHECK (OF) command is enabled, the Offset
Check will be performed at the beginning of each fastening cycle. OFFSET CHECK 7
Self-Check (Zero and Calibration) Input (Normally Open)
Used to perform the System's Self-Check function. The Self-Check
input requires a pulse of at least 50 milliseconds to initiate the Zero
Check and Cal Check. The Busy output signal will activate and the
Ready output signal will deactivate during the self-check cycle. After
the values have been checked (for all Axis Units) and are verified to be
within limits, the Accept light on the Main Unit will illuminate. If the data
is outside of limits, the Reject light on the Main Unit will illuminate, and
an Abnormal signal will be output to the affected Axis Unit(s). The
self-check is performed automatically each time the System is powered
up. (Refer to Section 9.4 Axis Unit Abnormal for more information
regarding System Self-Checks.) SELF-CHECK 6
NOT USED 5
Start Cycle Input (Normally Open)
The Start input automatically resets the previous cycle, clears all data
to zero, and initiates the next fastening cycle.The Start input requires a
pulse of 200~500 milliseconds if the Machine Configuration screen is
set up for AUTOMATIC Start input. If the Machine Configuration
screen is set up for DEADMAN (hand-held operations) input, the Start
input must be maintained "on" for the entire cycle. START 4
