TROUBLESHOOTING
DEFINITION
FUNCTION
K4 Relay
K4-24VAC double pole relay is the Fault relay and one set of contacts is open when the door is
in a fault mode and both sets of contacts are energized when the door is operating properly.
K6 Relay
K6-24VAC single pole relay is an optional relay, that is required when the pre-announce
to close option is chosen.
Limit Switches
The Open, Closed, Photoeye, and Alternate open limit switches are a normally open device and
should only be closed when the switch is in-line with the magnet. If the switch is closed when it
is not in-line with the magnet, replace the switch.
a) To adjust open limit switch, run door in the open position, and align 120 groove pulley
magnet with the (red) open limit switch, by loosening the bolts and belt.
b) To adjust the closed limit switch, pull the brake release lever and lower door so the curtain
bottom loop is sealing on the floor. Loosen thumb screw and align (black) closed limit switch
with the 120 groove pulley magnet. Tighten thumb screw.
c) Run door and test operation.
Motor phasing
If open button is pressed and the door closes, the following needs to be checked:
a) Check overload and contactors for proper voltage.
b) Phasing is reversed, reverse wires in terminals, V and W.
Motor will not run
If door will run will given an activation, check the following:
a) Faulty or tripped K0 overload relay.
b) Faulty K1M or K2M contactors.
c) Check voltage and for loose wires at terminals, U, V, and W and wires on the contactors and
overload relay.
Motor 208V-240V
208V-240V motor will have 5-7 ohms on normal readings.
Motor 460V-480V
460V-480V motor will have 20-23 ohms on normal readings.
Motor 400V
400V motor will have 23 ohms on normal readings.
Motor 575V
575V motor will have 34 ohms on normal readings.
Open/Reset Push Button
The open/reset push button has 2 functions. The first function is when the button is (not used
with LCD display) pressed, an command to open the door is given. The second function is to
reset the door when it has been broken away. When the door is broken away the light will flash
and the door will not operate from an activation command. At this point the button can be used
as a “Jog Button” to refeed the curtain back into the sideframes and to get the door at a
workable height to hook the trolley magnets back up to the magnet cups. The light will continue
to flash until the door breakaway mechanism is hooked up and the open/reset button is pushed.
Reversing Photoeye’s
The photoeyes are wired to the 24VAC circuit and are wired as normally closed when there is
power to the unit and the photoeye is aligned with the reflector or the source photoeye on a
thru-beam device. There are 3 lights on the photoeyes. Yellow is for power, red and green are
for proper alignment, if the eyes are not aligned properly, turn the adjustment screws or loosen
the mounting brackets. The photoeye’s are set to the “Light Operate” mode. The photoeye’s will
reverse or hold the door open when the photoeye beam is blocked. When the beam is not
broken, the door will auto-reclose.
Terminals
The following are commonly used terminals:
a) Terminals 63, 64, 65 are Auto-Reclose.
b) Terminals 1, 2, 3, 4, 57, 58, 59, 61 are common.
c) Terminals 53, 54 are 24VAC.
d) Terminal 13 is Toggle Mode.
e) Terminals L1, L2, L3 are the incoming power terminals. All 3 legs of the incoming power
MUST BE the same between each other for the door to operate.
Transformer
The standard transformer is a tri-volt transformer that takes an incoming voltage of 208V, 230V,
and 460V and converts it to 110VAC and 24VAC. An optional transformer is available for 380V,
415V and 575V doors.
a) 208V(Taps H1-H2) 6.8 Ohms
b) 230V(Taps H1-H3) 7.5 Ohms
c) 380V(Taps H1-H2) 18.4 Ohms
d) 460V(Taps H1-H4) 27 Ohms
e) 415V(Taps H1-H3) 20.5 Ohms
f) 575V(Taps H1-H4) 29 Ohms
g) 120V(Taps X1-X3) 4.4-4.8 Ohms
h) 24V(Taps X1-X2) .4 to .6 Ohms
Turn-Tite Seal
The Turn-Tite seal is used to seal the top of the door. It is adjusted by removing the seal from the
hook and loop fastener on the curtain and positioning it so it makes solid contact with the wall seal.
Voltage Change
To change the voltage, see step below:
a) Change transformer taps, fuses, and overload settings per electrical diagram or see
individual troubleshooting section.
b) Change motor wiring per junction box diagram.
c) P.R.O. system doors require a new inverter.
Wind Pressure
If the door is blowing out because of high wind or negative pressures, check the flowing:
a)The sideframe cover to sideframe gap
MUST BE
at 3/4”, if it is larger than that, the wind clips
will slip through the sideframes.
b) Check to make sure the curtain has all the wind clips in place.
c) The sideframes are mounted at the proper width distance.
