Because the RESET input clears all fastening data and discrete outputs, it should only be activated
to clear a system Abnormal or to perform a Zero Level Check. The system will automatically reset
with each fastening start. A manual RESET activation between cycles could result in data loss.
The REVERSE signal must be maintained for the duration of the desired REVERSE function.
The STOP input is normally closed and enables all other functions. When open (OFF), all
operations cease and all inputs / outputs become inactive.
The START signal will not operate during RESET, REVERSE or ABNORMAL signal activation. A
pulse of 200~500 milliseconds is required for AUTO START mode. For DEADMAN mode (Used
mainly in handheld applications), the signal must be maintained for the complete fastening cycle
(until BUSY goes low).
When the ABNORMAL signal is activated, the system must be RESET before normal operation will
resume.
REJECT & ACCEPT signals are maintained until the start of the next cycle or on a RESET.
READY indicates when the system is ready to start.
It is recommended when changing sequences that the Sequence Select outputs be used to verify
that the sequence has been changed before issuing a start signal. Delay from Sequence Select
input to Sequence Select output is approximately 5ms.
