{ Because the RESET input clears all fastening data, discrete outputs and communication
buffers, it should be activated only to clear a System Abnormal or to perform a required Zero
Check. The System will automatically reset with each fastening and a manual RESET
activation between cycles could result in data loss. The RESET signal requires a pulse of
100~500 milliseconds.
{ Once set on, the ACCEPT or REJECT signals will latch on until the start of the next cycle.
{ The START signal will not operate during RESET, REVERSE or ABNORMAL signal
activation. The START signal requires a pulse of 100~300 milliseconds for the AUTO START
mode. If the system is set-up in DEADMAN mode (Used mainly in handheld applications), this
signal has to stay on during the complete fastening cycle (until the BUSY signal goes low). If
the signal is prematurely disabled before the end of cycle, the spindle will immediately stop.
{ When the ABNORMAL signal is active, normal operation will cease. The Abnormal problem
must be cleared and a RESET must be input to clear the Abnormal output to begin normal
operation.
{ When using WORK SELECT inputs to change parameters activate or select the WORK
SELECT inputs at least 200ms BEFORE activating the start signal.
