Accessory cable C5/C5X is required for PFC’s with the plug connector
option (Option-P quick connect option), and for PTF’s on which a
connector is standard).
Option-N
Connect the shielded feedback cable to terminal block TB2 on the PCS PC Board,
allowing for proper strain relief. Follow the same wire color designation defined
in the table from the previous section.
Be sure to use a shielded cable, or noise will couple to the feedback
signal creating noise in the system resulting in poor operation of the
system.
Option-Q
Connect the Quick Connect feedback cable (2 meter Model PCS-CBL-FBK or 5
meter Model PCS-CBL-FBK-X) between the PCS and the actuator. The Quick
Connect Option, Option-P, must be ordered with the PFC for mating cable to
work. The Quick Connect plug connector is standard on the PTF.
6. CONNECT THE COMMAND SIGNAL CABLE
Standard Enclosure
Connect the Command Signal Cable from the Main Control to the PCS. This
cable should be a 4-conductor, twisted-shielded cable, 22 gage minimum. A 2-
conductor cable can be used if @ Position and Current Position signals are not
utilized. The cable’s outside diameter must be between 0.114 and 0.250 inch.
Pass the cable through the remaining bulkhead strain relief and connect the
individual wires to PCS Terminal Block TB4 on the PC Board as follows:
Input (Command Signal) A positive analog input signal to the PCS control of
0-10 VDC or 4-20mA which defines the desired
position of the PFC rod or PTF shaft..
Current Position A positive analog output voltage (0-10 VDC)
from the PCS which corresponds to the current
position of the PFC rod or PTF shaft.
@ Position A digital output signal that is normally open and
switches to ground when the actuator is within the
Deadband zone (Current Position equals Command
Signal).
Ground This is the power return path and must connect to
both the Main Control and the PCS control ground
connections.
Shield Connect only to the PCS. It should not be
connected to the Main Control end of the cable.
