For assistance in wiring, refer first to the overall sche-
matic in figure 8 which includes references to more
detailed wiring schematics that show specific sections
of the system. Also refer to figure 9 for a schematic of
the power transformer connections.
Wire sizes are shown in the schematics in square milli-
meters (mm2). Approximate equivalents in AWG sizes
are:
mm2 AWG
0.50 20
0.75 18
1.5 16
2.5 12
Schematics for some special inputs (for example, input
from a Rolm computer) are not included in this instruc-
tion manual. If the schematics in this manual do not
appear to cover your equipment, determine the serial
number of the unit, and contact your Fisher Controls
sales office or sales representative.
Motor, limit switch, and feedback potentiometer wiring
is connected to the actuator before the unit is shipped.
The limit switch and feedback potentiometer wires are
provided with an appropriate connector at the actuator.
It is necessary to connect the other ends of these
wires to the Stepmotor Interface, as well as the alter-
nating current power and connecting wires from your
computer or other controlling device to the Stepmotor
Interface.
The Stepmotor Interface has a wire access plate on
top and bottom. Connect all wires through one of those
plates.
Note
It is necessary to drill holes in one of the
wire–access plates and provide connec-
tors for the power supply wires and the
control wires from your computer or
controlling device.
WARNING
To avoid personal injury from electrical
shock, keep hands and tools out of the
Stepmotor Interface and away from the
terminal connections on the actuator
whenever power is applied to the control
box or actuator. Always disconnect pow-
er before making or checking electrical
connections.
Remove the screws and the appropriate wire access
plates. Drill the required size holes and install connec-
tors that are appropriate for the installation location.
Replace the wire–access plate. Be sure to tighten the
connector and access plate securely.
Unlock the cabinet and open it. Then proceed to the
following instructions.
