4.7 Wiring PLC I/O
All interface devices must accommodate active true low logic for correct operation with
AFC1200 inputs and outputs (I/O). Outputs are rated at 12~24 VDC, 200mA. When
activated, open collector sink outputs (normally high) pull the input device signal low
(0 VDC). Inputs are sourced (normally high) and activated when pulled low (0 VDC).
CAUTION:
The PLC I/O wiring must be routed a minimum of 300 mm away from any transient high
voltage sources. Cable length must not exceed 50 feet.
DO NOT connect a positive DC voltage source to the input or output commons.

FIG. 4-7-1 Main Unit PLC Connector
CAUTION: DO NOT CONNECT A POSITIVE DC VOLTAGE SOURCE TO THE INPUT
COMMON OR OUTPUT COMMON, OR DAMAGE MAY RESULT.
Reverse Spindle Rotation Input (Normally Open)
All spindles 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 pushbutton on the front of the Main Unit. REVERSE 3
Reset Input (Normally Open)
When active (on), this signal will clear all fastening data, discrete
outputs, and communication buffers. A Zero Check of all torque
transducers will be completed. During the Zero Check, the CHECK
lamp will illuminate, the READY signal will deactivate, and the ACCEPT
or REJECT lamp will 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 200~500 milliseconds. Do
not input this signal between cycles, due to the potential for data loss. RESET 2
Emergency Stop Input (Normally Closed)
This signal must be active (on) for controller operation. When this
signal is inactive (off), all controller operation ceases, all spindles in
motion will stop, and all communication ports & input/outputs will be
disabled. STOP 1
