RELAY CONTROL SYSTEM
ELECTRICAL CONNECTIONS, MOTOR ADJUSTMENTS, AND ACCESSORY WIRING
MODEL 2000
ELECTRICAL CONNECTIONS:
There are two independent and unique aspects of the wiring configuration for your Motorized
Vertical Curtain Door. These are the 115VAC 60Hz power wiring and the low-voltage control
wiring. While the low-voltage side of the control system can be configured and properly wired
by anyone who has a rudimentary understanding of electrical circuitry, the power wiring should
be performed by an electrical professional and done in such a manner to conform to all local
and national wiring codes and regulations.
READ THIS MANUAL CAREFULLY. OBSERVE WARNINGS
AND PRACTICE CAUTION WHEN INSTALLING,
OPERATING, OR MAINTAINING YOUR GOFF’S
PRODUCT.

RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS
115VAC POWER WIRING:
The external operator requires 115VAC, 60Hz with a current draw of 5A (1/2 HP PSC
inductive motor). Make sure that the branch circuit and conductor size can support
this load requirement. Low voltage can cause erratic behavior and operator
overheating.
Locate the rotary selector switch on the printed circuit board and ensure that it is set to
“C2” (position 0) as shown in the following photo:
Power and ground are connected to the operator as shown in the following photo
(Photo 19):

CONTROL PANEL / MOTOR CONNECTIONS:
The following schematic shows your Motor and Limit Control wire connection points
within the control panel:
These two cables then run up to your motor and connect to your Motor Winding wires,
and Limit Switches respectively. See diagram on next page.

RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS
The operator supports NEMA-1 and NEMA-4 3-button control stations with N/O “Open” and “Close”
buttons. The “Stop” buttons must be N/C. The low-voltage control connections for the primary (first)
station should be made with the 4-conductor “Thermo Wire” that was included with your kit. Although
the color codes are arbitrary, Goff’s has selected the following standard:
LIMIT & INTERNAL SAFETY SWITCH:
-Locate the 6 conductor wire marked ‘control’ and remove the insulative material, preparing
each conductor to make the following connections; (SEE NEXT PAGE FOR DIAGRAM)
oBlue from 6 conductor to N/C side (right) of open limit switch
oBlack from 6 conductor to N/C side (right) of close limit switch
oWhite from 6 conductor to COM side (left) of open limit switch
oGreen from 6 conductor to COM side (left) of close limit switch
oOrange from 6 conductor to yellow thermal protection wire
oRed from 6 conductor to black from hand crank safety switch
oGray from hand crank safety switch to its own connector

The operator supports NEMA-1 and NEMA-4 3-button control stations with N/O “Open” and “Close”
buttons. The “Stop” buttons must be N/C. The low-voltage control connections for the primary (first)
station should be made with the 4-conductor “Thermo Wire” that was included with your kit. Although
the color codes are arbitrary, Goff’s has selected the following standard:
Green - (8) COM
Red - (9) STOP
Blue - (7) OPEN (UP)
White - (6) CLOS (DOWN)
Single-station control installations are performed by simply running the control wiring
between the control station and the operator, and attaching the appropriate wires to
the screw terminals as indicated in the following photos:

RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS
Additional NEMA-1 and NEMA-4 control stations (along with Pull Cord and RF Interfaces) can be added
to the Goff’s operator. Please see the “Addendum” at the end of these assembly instructions for further
wiring information.
PHOTO-EYE:
The OEM cable for the photo-eye will not be long enough to reach the external operator in many
installations. We have included a junction box, cover, glands, wire nuts, and some additional 4-
conductor wire so that an extension can easily be fabricated.
The wiring convention for the photo-eye is as follows:
Brown - (1) 24Vac (Power)
Blue - (2) 24Vac (Power)
Black - (5) SENS
Orange - (3) COM
White - Not Used
Remove the protective rubber cap from the photo-eye head unit and open the clear plastic door. Set
the slide switch to “Dark Operation” (DK) by sliding it to the “left”.

RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS
Enable power to the operator and observe the LEDs on the photo-eye head unit. The RED and YELLOW
LEDs should be illuminated. When the crossbeam is broken (blocked) the RED LED should go out and
the GREEN LED should illuminate. Adjust the mechanical alignment of the head unit and the sensitivity
of the circuit to ensure reliable and robust operation. Close the clear plastic door and re-install the
protective rubber cap.
SETUP AND OPERATION:
After the power wiring has been installed (and power has been enabled to the unit) it will be
necessary to set the curtain door end-stop positions. Care should be exercised during these
operations to avoid damage to the assembly and ensure a long service life of the unit. The door
will open with only a momentary pressing of the “Open” button, but it will be necessary to press
and hold the “Close” button in order to get the door to move down. This functionality will be
changed when you do the final programming.
LIMIT & INTERNAL SAFETY SWITCH:
-Locate the 6 conductor wire marked ‘control’ and remove the insulative material, preparing
each conductor to make the following connections; (SEE NEXT PAGE FOR DIAGRAM)
oBlue from 6 conductor to N/C side (right) of open limit switch
oBlack from 6 conductor to N/C side (right) of close limit switch
oWhite from 6 conductor to COM side (left) of open limit switch
oGreen from 6 conductor to COM side (left) of close limit switch
oOrange from 6 conductor to yellow thermal protection wire
oRed from 6 conductor to black from hand crank safety switch
oGray from hand crank safety switch to its own connector

FINAL PROGRAMMING:
Fully close the door.
All programming changes on the operator must be made with the door in the
fully closed position! Verify that the door is fully closed and that the close LED is
illuminated.
The Maximum Run Timer (MRT) helps to protect the door and operator from damage
should there be a bind or other problem. It does this by limiting the amount of time
that the operator will run continuously. To set the time, position the rotary switch on
the printed circuit board to the “D” (Run Tm) position as shown in the following photo:
Press the “Open” button and allow the door to reach the fully opened position. The
MRT is now set. Immediately proceed to the next step.
Convert the operator from “Constant Pressure to Close” (C2) configuration to
“Momentary Pressure to Close” (B2) by setting the rotary switch on the printed circuit
board to the “1” position as shown in the following photo:

The assembly, installation, and set-up of your Goff’s Motorized Curtain Door is now complete, and it is
ready for typical operation. Re-secure the corner screws on the “Box Valence” of the door and install
the cover on the operator. It is a virtually maintenance free unit and should give you years of reliable
service.
Operational Note: Larger door are equipped with an internal torsion spring
counterbalance system. These doors can be identified by a “hitch pin” and tag
installed on the non-operator end of the roll-tube center shaft. This pin is to
remain installed during the normal operation of the door. It should only be
removed for maintenance/service purposes, and ONLY when the door is in the
fully open position. Removing the pin when the door is closed or partially
closed may cause damage to the system and personal injury.
We want to thank you again for your business and the opportunity to partner with your firm on this
project. Please don’t hesitate to contact us if you have any questions regarding these instructions or
encounter any problems with the installation or performance of your door.
