FEC AFC1100 - Manual (Page 10)

)(& ,QF
All interface devices must accommodate active true low logic for correct operation with
AFC1100 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 output common.

CAUTION: DO NOT CONNECT A POSITIVE DC VOLTAGE SOURCE TO THE OUTPUT
COMMON, OR DAMAGE MAY RESULT.
Reverse Spindle Rotation Input (Normally Open)
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 pushbutton on the front of the Axis 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 the torque
transducer will be completed. During the Zero Check, 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), controller operation will stop, and input/outputs
will be disabled. STOP 1
