FAQs

Pressing P1, P2 and P3 does not show any reaction
The gate opener doesn't respond at all; no LED is
on.
Immediately after the gate has started moving, it
stops and reverses.
Gate can only be opened
"
Timer to close" doesn't work.
The control board does not work any more using
the transmitter, only with the switch and even then
only as long as a button is pressed and kept
pressed.
The gate opener doesn't respond at all, although
the controller has been connected (LEDs are on).
Control board does not work with transmitter
Control board does not work
Gate doesn't open completely
Travel distance can't be programmed
The operator sometimes movess slowly
Limit switches OPEN and CLOSED nicht correctly
indicated
Gate opens instead of closing automatically
(Timer to close activated)
The remote control's range is too short.
The gate must follow a slope.
Possibly power failure.
Obstacle in area of gate.
Gate rough running (consult dealer)
photocell blocks
Photocell, a safety edge or the emergency
stop disables the control board
Only one photocell was connected for OPEN
1. Remote control not programmed.
2. LEDs indicate a fault.
3. Photocell connected incorrectly.
4. Motor terminal possibly not connected
properly.
1. transmitter not programmed
2. photocells block
3. DIP "RADIO PROGRAM" is on
travel distance not programmed
Gate heavy / rough running
1. DIP setting not correct
2. see Diagnostic LED
3. interferences in wiring of photocells, switch
or safety edge
4. Gate moves for 1 second only and stops
without reversal during programming
5. Magnetic limit switch
Powerfailure
incorrect programming
incorrect programming
The installation of an external antenna is recommended as the controller with the short cable
antenna is located either behind the post or near ground level in most cases. The optimum
location of the antenna is as high as possible in all cases. An appropriate antenna with
installation kit can be obtained as an accessory.
Not recommended! Change gate! The gate can move in an uncontrolled (dangerous) manner if
the gate opener has been released. A stronger force is needed in the upwards direction of the
slope and then, in the opposite direction, the gate opener's force is too strong.
DIP "RADIO PROGRAM" must be off
1. Check conductor and zero conductor.
2. Check house fusing.
Check gate area for objects
check photocells
reprogram travel distance
Function and connection must be
checked
Only works if the 2-cable photocell 771E(ML)
or 772E(ML) installed.
At least 1 pair of photocells active in
OPEN or CLOSED must be connected
1. Programming remote control.
2. Find and rectify fault(s) (see description of
diagnostic LEDs).
3. Check photocell connection / programming.
4. Check terminals and connections.
1.Program transmitter
2.Check photocells, check diagnostic LEDs
3. DIP "RADIO PROGRAM" must be off.
Program travel distance. See initial
operation / diagnosis LED
re-program travel distance
consult dealer/specialist
1: follow the instruction of "Initial Operation"
closely
3: remove for checking, then re-program
travel distance
4: check RPM sensor/Encoder on control
board
5: install magnetic limit switch properly
Common procedure. After powerfailure the
operator performs a selftest. Depending on
the operator model this can take a few
seconds or a complete cycle. Do not interrupt
this test via remote control or switch,
otherwise the limits may change. If this is the
case reprogram travel distance using P1.
During programming the limit switch OPEN
must be reached using P1, then limit switch
CLOSED. Switching motor cables is not
required.
repeat programming as described in these
instructions
