WIRING TO PANEL
Incoming Power
Three Phase power coming from a FUSED DISCONNECT is wired into T1, T2, and T3. Located on the
disconnect.
Voltage Selector Jumper (J2)
Check J2 for the proper incoming voltage level. This jumper wire comes from the motherboard and is
terminated on a terminal below the control transformer. This is factory preset and should not normally need
to be changed.
Pneumatic safety edge (if equipped)
The pneumatic edge pressure switch is wired to a set of terminals 7A and 8A for rapid roll doors, which is
mounted on the din rail right below the motherboard. (Required for door operation.) Re-Coil-Away and Rapid
Roll 392 doors do not have this resistor in the control panel but located on the end of the safety edge
Electric Edge Connection (if equipped)
Connect the electric edge directly to terminals 7 and 8 (edge is not adjustable). To test, (turn power on)
bump the rubber safety edge with your hand observe LED 6 (see Figure 5 for location), it should flash on
briefly. The edge is now operational.
Ground Bar
All grounds coming into the panel should be terminated on the ground bar at the bottom of the panel.
Wiring of the Motherboard
The motherboard component layout and numbering is shown in Figure 7 for ONE-speed motors, and in
Figure 8 for TWO-speed motors. Also refer to wiring diagrams on pages 18-30 for the following: Ovitor
motors Figure 9, for Bonfiglioli motors Figure 10, for GFA drives. Table 1 shows the motherboard terminal

Electrical Start Up
WARNING
First you must determine what type of limit box you have. Consult Figures below to determine this.
Figure 14 is the STROMAG limits box. Figure 15 is the TEMEC limit box. Figure 16 is the GFA limit
Box.

Limit Switch Coarse Adjustment
Refer to the Electrical drawing WD501-0V000 for wiring of the Temec/Ovitor limit switch. For the
wiring of the Stromag Limits refer to Electrical drawing WD501-BF000. For GFA LIMIT Boxes refer
to electrical drawing WD501-GF02.
Warning
Rotation of the open limit cam in the wrong direction or incorrect phasing may cause the
bottom beam assembly to jam into the top roll.
1. Remove the limit switch box cover, and manually bring the door down to one foot below the full
open position. Observe the rotation direction of the limit cams while the door moves.
 The limit switch box for the TEMEC/Ovitor (figure 15) is located on the gearbox; The Temec
style limit uses the threaded brass bolt to finely adjust limit switch cams. NOTE: A SMALL
CHANGE IN THE CAM POSITION WILL RESULT IN A LARGE CHANGE IN THE
MOVEMENT OF THE DOOR.
 The Stromag limits (figure 14) module is attached to the Bonfiglioli Motors via the chain
drive. The Stromag sytle limits use a screwdriver to rotate the adjustment screw
 The GFA (figures 16 & 17) limit switch box is located behind the motor and under the
gearbox.) Using the included Allen wrench loosen and then rotate the open limit cam (figure
17 &18) until it makes contact with its associated micro switch. Then lock the cam with the
Allen wrench. The RED open and close safety limit cams are pre-adjusted and are
piggybacked to the Green open and close limit cams. If this safety point needs to be
corrected this can be adjusted using the fine adjustment screw to advance or retard the
position of the red cam in relation to the position of the green cam. The red cams are so the
door stops safely if the direction of the rotation is reversed or the open limit switch fails.
During normal operation the RED cams should never make contact with their switch but
should be close enough to activate if the primary limits fail.
2. Rotate the open limit cam until it makes contact with its associated micro switch.
3. Move the door to one foot from the fully closed position. Observe the rotation direction of the
limit cams while the door moves.
4. Rotate the closed limit cam until it makes contact with its associated micro switch.
Turning on the Door Controller
When the door controller has been wired correctly, the switch SW1 and SW2 settings are complete,
and the coarse limit adjustment is complete, the power may be turned on. Upon power up, the door
controller will do an initial test for 3 seconds to see whether the software and the RAM are working
properly. During this 3-second test, the controller will not respond to any open or close signals and
the door will not open or close and the red illuminated button on the control box will flash.
If the test detects a failure, the red illuminated button will illuminate constantly, the alarm relay will
be activated, and the door controller becomes locked.
When the initial-test is over and no fault has been detected, the controller is ready to work.
Phase Check
Note: in this step it is assumed that the door is still closed from the coarse limit-setting step.

Part # 6410T0008 Rev.F
-16-
1. Be prepared to press the STOP button. (Stop on the front panel is a momentary stop only!
Door can be activated by motion detector, floor loop, or any activation device) It is highly
recommended that ALL automatic or remote activations be disconnected during the
startup of the door. This will eliminate unwanted activations which can create startup
issues.
2. Push the open impulse button. The door should open at full speed.
2.1. If the door starts to close, stop the door immediately by pressing the STOP button and swap
the position of the incoming power wires to T1 & T2.
2.2. If the door opens, make sure it stops at the open limit. If it goes beyond the open limit as set
in the coarse limit-setting step, stop the door immediately and troubleshoot the limit wiring
and/or setting.
3. Repeat this check until the door opens to top limit and stops at the close limit.
Hold-to-Run-Function
If the safety edge or safety photocells (safety circuits) have any fault(s), the door will no longer
close automatically, and the system will go into Hold-to-run mode. An illuminated Stop button on
the control panel indicates hold-to-run mode.
If the Hold-to-run-mode is activated, it is not possible to close the door via external activators or
signals.
It is necessary to push the “Close” button to reset the door controller. Every other signal to reset will
not have any effect.
Reset of the Hold-to-run mode will occur when both safety circuits are working again and pushing
the CLOSE button on the control panel successfully closes the door.
Input Device Check
Press the STOP button to prevent the door from moving. Operate each applicable input device as
listed in Table 3 to verify device wiring. Refer to Table 4 to understand the proper light indication.
When finished, restore the door from hold to run mode as described above.
Limit Switch Fine Adjustment
Refer to the limit switch appendix for details on the specific limit switch type used on your door.
1. Make sure the door can be actuated to open and close properly and that the door stops at the
coarse limit settings.
2. Make small adjustments to the cams and cycle the door open and closed to observe changes in
the limit settings.
3. Continue to finely adjust each cam until the desired door limits are attained. Once the door limits
are adjusted correctly and the door is operating satisfactorily. Replace the limit switch box
cover. On the Temec style and GFA style of limit box ensure the limit cams are tightened and
locked.
The Crash-Function
(For doors with breakaway and impact detection only)
if the door has been impacted and the bottom beam has been knocked out of the side-frame, the
door stops immediately and the red illuminated push button is lit.

Part # 6410T0008 Rev.F
-17-
Once the door has been impacted, to restore full function of the door, press the ▲ up arrow button.
The door then will go to full open and reset itself close.
Runtime Monitoring
The controller has an internal timer to measure the door run time when opening or closing. The
timer expires after the door runs continuously for 20 seconds (some doors have a 40 second
EPROM). If this occurs, the door will immediately stop and the red button on the panel will be lit
solid. To reset this condition, disconnect main power (off). Verify that the door is not binding or you
have a motor/gearbox problem. After this check, then reapply power.
Safety Circuit Limit Box (GFA Drives
Only)
The terminals 21 to 28 on the limit
switch figure 18 are reserved for the
safety circuit. An interruption of the
safety circuit causes the control voltage
to be interrupted. Electrical operation is
no longer possible when this occurs.
Photocell Cut-off (GFA Drives Only)
The limit switch (S6) must be adjusted
to bypass the photocells when the door
is approximately 8 inches off the
ground. This allows the bottom loop on
the bottom beam assembly to clear the
photocell and not cause the door to
reverse. Not used with Light Curtains.
Inertia Brake Wiring (if Equipped)
(Re-Coil-Away Doors ONLY with chain drive and without counter balance springs)
The inertia brake needs to wired in order for the door to operate. Refer to electrical drawings for
wiring points. If the red indicator is extended from the housing the electrical contact will be in an
open position and thus preventing the door from operating.

Pressure Switch Adjustment (if Equipped)
Bump the rubber safety edge with your hand observe LED
6 (see Figure 9 for location), it should flash on briefly. If the
LED does not flash, adjust the switch. The pressure switch
is located on the bottom beam see Figure 19. Remove the
cover of the pressure switch enclosure. Rotate the white
plastic screw on the pressure switch clockwise with a small
screwdriver until the LED 6 turns on. Then rotate the screw
counter-clockwise until LED 6 turns off, and then rotate an
additional ¼ turn. Test the safety edge and observe LED 6
(it should turn on momentarily whenever pressure is applied
to safety edge). (Note: LED 26 turns off if edge fails pulse
test when in pneumatic mode = not used.)
