ELECTRICAL CONNECTIONS, MOTOR ADJUSTMENTS, AND ACCESSORY WIRING
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.

Summary of Contents for Goff's 2000
- Page 1 PRODUCT. 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.
- Page 2 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.
- Page 3 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...
- Page 4 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 &...

- Page 7 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.

Page 8: Setup And Operation
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. - Page 9 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.
- Page 10 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.
- Page 11 Addendum USING THE BUILT-IN AUTO-CLOSE TIMER (TTC): The Auto-Close Timer (Timer to Close) will automatically close the door from the fully open position (only) after a preset amount of time has expired. To program the delay (dwell) time (the factory default is 5 seconds), perform the following operations: Fully close the door and verify that the Close LED is illuminated.
- Page 12 The door will now operate in TTC (Auto-Close Timer) mode. To disable the TTC mode (without altering the programmed delay time), fully close the door and set the rotary switch on the printed circuit board to the “1” (B2) position. The TTC mode can be re-enabled by setting the rotary switch back to the “5”...
- Page 13 Remove the cover of the NEMA-4 station and note the location of the N/O and N/C terminals for each button. The N/O terminals are located closer to the base and are on the “right” side of the station. The N/C terminals are raised and are on the “left” side. Use a short piece of green wire from the 5-conductor “Thermo Wire”...
- Page 14 Locking NEMA-4: Although the color codes are arbitrary, Goff’s has selected the following standard: Green Common Red - Stop Yellow Stop Return Blue Open (UP) White Close (DOWN) Remove the cover of the Locking NEMA-4 station and note the location of the N/O and N/C terminals for each button.
- Page 15 NEMA-1: Although the color codes are arbitrary, Goff’s has selected the following standard: Green Common Stop Yellow Stop Return Blue Open (UP) White Close (DOWN) Remove the cover of the NEMA-1 station and cut the bonding strip between the Close and Stop button terminals.
- Page 16 Route the cable through one of the station knockouts and carefully reinstall the cover. Make sure that the cover is installed properly and that the buttons work freely. The other end of the 5-conductor “Thermo-Wire” is attached to the control terminals at the external operator.
- Page 17 The wiring for the additional control station is now complete. You can continue to add control stations by following this same procedure. Connect the blue, white, and green wires to the corresponding terminals in the operator. Disconnect the red wire from the previous station from the #9 Terminal, connect it to the yellow wire for the new station (wire nut), and connect the red wire for the new station to Terminal #9.
- Page 18 Switch Wiring: Control wiring should be attached to the NEMA-4 Single Button Control Station at the lower two N/O terminals (#’s 13 & 14) as shown in the following photo: Control wiring should be attached to the Pullcord Switch Stations at the two N/O terminals as shown in the following photo: RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS...
