SIGNAL NAME DESCRIPTION
1 1 STOP
Emergency Stop Input (Normally Closed)
This signal must be active (on) for controller operation. When this
signal is inactive (off), controller operation will stop, and input/outputs
will be disabled.
AVAILABLE IN STAND ALONE OPERATION ONLY,
2 2 RESET
Reset Input (Normally Open)
When active (on), this signal will clear all fastening data, and discrete
outputs. A Zero Check of the torque transducer will be completed.
During the Zero Check, the ACCEPT or REJECT lamp will light to in-
dicate the result of the Zero Check. If the System has been disa-
bled by an Abnormal output, the System will not return to normal op-
eration until the Abnormal condition has been corrected, and this sig-
nal has been input for 200~500 milliseconds.
Do not input this signal between cycles, due to the potential for data
loss.
AVAILABLE IN STAND ALONE OPERATION ONLY,
3 3 REVERSE
Reverse Spindle Rotation Input (Normally Open)
The spindle will rotate in an opposite direction for as long as this sig-
nal is activated (on) and maintained. The Reverse input functions
the same as the reverse push-button on the front of the SAN unit.
AVAILABLE IN STAND ALONE OPERATION ONLY,
4 4 START
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 SAN Unit DIP switches are set
up for AUTOMATIC Start input. If the SAN Unit DIP switches are
set up for DEADMAN (hand-held operations) input, the Start input
must be maintained "on" for the entire cycle.
AVAILABLE IN STAND ALONE OPERATION ONLY,
5 5 BYPASS
Spindle Bypass Input (Normal Open)
When active, all functions of this spindle are bypassed, and the By-
pass output is active. (Available in both Stand Alone & Multi set-
up)
6 6 SYNC COMMON
Input common signal for input 8 "SYNC" signal.
AVAILABLE IN STAND ALONE OPERATION ONLY,
7 7 SYNC COMMON
Input common signal for input 8 "SYNC" signal.
AVAILABLE IN STAND ALONE OPERATION ONLY,
