SIGNAL NAME DESCRIPTION
1 INPUT COMMON
Input signal common. Connection to either +12 ~ 24 VDC or
OVDC common required. (Reference PLC wiring example)
2 INPUT RESET
Reset Input
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, ACC (Accept) or REJ
(Reject) will be shown on the front display light to indicate the
result of the Zero Check. If the System has been disabled by an
Abnormal output, the System will not return to normal operation
until the Abnormal condition has been corrected and this signal
has been input for 100~500 milliseconds.
Do not input this signal between cycles due to the potential for
data loss.
3 INPUT REVERSE
Reverse Spindle Rotation Input
The spindle will rotate in an opposite direction for as long as this
signal is activated (on) and maintained. The Reverse input
functions the same as the reverse push-button on the front of the
MNR display unit.
4 INPUT START
Start Cycle Input
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 100~300 milliseconds if the MNR Unit
DIPSW1 switches (bit 1) are set up for AUTOMATIC Start input.
If the MNR Unit DIP switches are set up for DEADMAN input, the
Start input must be maintained "on" for the entire cycle (until the
BUSY signal goes low).
5 INPUT WORK SELECT 0
Work / Parameter Select Input (Normally Open)
These 3 inputs form a binary code which is capable of selecting
up to 8 different sets of Fastening Parameters. These inputs are
read at the rising edge of the START signal and select the
parameter to run according to these inputs.
Refer to Section 4.7.2 Work / Parameter Select Table.
6 INPUT WORK SELECT 1
7 INPUT WORK SELECT 3
