INDICATION OF THE DIAGNOSIS LED
The LED diagnostics show the first upcoming issue. If several issues are existing the LED diagnostics may not show them.
Indication Description
1x blinking Motor 1 has insufficient connection to control board
Control board does not see motor sensor.
Travel distance programming was not successful
2x blinking Motor 2 has insufficient connection to control board
3x blinking Limits for motor 2 have not been accepted
A: After or during programming travel: Wing 1 did not
open wide enough and did not meet the integrated
passpoint which is located inside the operator halfway
above the spindle.
B: Motorcables have insufficient connection to contol board
Yellow or white cable not wired or badly connected
4x blinking Limits for motor 1 have not been accepted
5x blinking Travel has not been programmed
The process of programming has been interrupted
6x blinking Force to operate the gate is too high
A: Gate is out of order
B: Gate is rough-running
C: Gate stopped through windload
D: Wrong mechanical installation
7x blinking Photocells 1 block installation + LED PHO1 =OFF
A: Object blocks photocells
B: Alignment of the sensors is incorrect
C: Power supply to photocells is insufficient
8x blinking Photocells 2 block installation
9x blinking Photocells 3 block installation
10x blinking Emergency stop switch blocks installation
11x blinking Safety edge blocks installation
A: Object obstructs safety edge
B: Defective safety edge
C: Power too low or broken wire in supply
12x blinking Power supply to control board is too low
A: Defective supply 230V or malfunctioning contact
B: Broken wire in supply cable (copper cable)
C: The battery (accessory) to operate the gate whilst
power failure is dead.
13x blinking EEPROM Fault
Power up failed
14x blinking Only LYN/SCS
Release lever OPEN
15x blinking Defect on relay or major electrical component
A: Overload
B: Bad wiring (wrong)
D: water in photocells (bad installation)
E: a photocell was connected before
but not removed (disconnected)
Remedy
Cables not wired or badly connected.
Check terminals precisely. Consider wire lengths
The gate must be closed completely before programming the
travel distance
Refer to 1x blinking
A: Open gate wide enough when programming the travel (50%
over maximum)
B: Check terminals precisely. Consider wire lengths
C: See 1x blinking (wiring)
Refer to 3x blinking
The gate must be closed completely before programming the
travel distance.
Refer to 5x blinking also
A: Repair gate
B: Check if gate can be easily moved
C: Do not operate gate in very windy conditions
D: Reprogram to achieve sufficient level of force
A: Remove object
B: Check alignment
C: Check cable widths and contacts
Refer to 7x blinking
Refer to 7x blinking
A: Check wiring
B: Check basic setting of control board (Jumpers)
A: Remove object
B: Check wiring. Check resistor 8.2KOhms
C: Check basic setting of control board (Jumpers)
A: Check electric contact
B: Check by electrician
C: Allow battery to charge 24 hours
Replace contol board
Close (re-connect) release lever,
Replace logic board
Check wiring
Reprogram the travel distance from gate fully closed
