Bimba PCS - Manual (Page 11)

For best positioning results, consider using a precision relieving regulator
and an air reservoir with a check valve before the regulator to ensure that
there are no pressure drops to the PCS system. You may want to install
mufflers into the exhaust ports of the valve manifold (the two outer ports).
This will make the system quieter during operation. Do not to use mufflers
with low flow rates; that may slow the actuator.

CONNECT THE POWER CABLE
Standard Enclosure
Carefully remove the enclosure cover. Use a two conductor cable, 22 gage
minimum, with an outside diameter between 0.114 and 0.250 inch. Pass the cable
through the bulkhead strain relief and connect to the POWER terminal block
(TB1) on the PCS circuit board (refer to illustration below). If a shield wire is
used, twist the Ground wire and the Shield wire together and connect to the
Ground terminal (do not terminate the other side of the shield).
Set jumper J02 for 4-20 mA or 0-10 V control voltage input in accordance
with the illustration above. Refer to Appendix A for air and electrical
connections to PFCN, PFC, and PT.
Option N
Connect a two conductor, 22 gage minimum shielded cable to the
POWER
terminal block (TB1) on the PCS circuit board. Twist the ground
and shield wire together and connect to the Ground terminal (do not
terminate the other side of the shield).
Deadband adjustment
You may adjust the
jumper on JO2 for 0-
10V (left and center
terminals connected) or
4-20 mA (right and
center terminals
connected) operation. Do NOT change the
jumper JO1. This
adapts the board for
use as PCS-4 through
PCS-8 operation.
Different valves must
be installed as well.
