PROGRAMS
The control board has 7 operating modes (programs). The desired
program is set using the dip switch "ON" or "OFF".
ON
DIP1
OFF
ON The various operating modes are assigned to the
DIP2
drives (see separate table)
OFF
ON
DIP3
OFF
E-lock
ON
As soon as an impulse is given, the drive moves the
gate in CLOSED direction and opens the relay for
activating the e-lock for one second. ( Function due to
DIP4
the various commercial e-locks available.)
Function disabled
OFF
Setting for Chamberlain photocells (770E/771E),
ON
complies with EN60335-2-103.
DIP5
Setting for relay-controlled photocells (100263E) or
OFF
other relay photocells.
ON
Preflash function of flashing light 2 seconds before the
drive starts.
DIP6
OFF Preflash function disabled
ON
Once the gate has fully opened, drive 1 moves the
gate with maximum force for 1 second in "OPEN"
DIP7
direction.
OFF
Function disabled
ON
Once the gate has fully closed, drive 1 switches off for
2 seconds to ensure that the e-lock engages. The drive
then continues
DIP8
to move the gate for 1 second in "CLOSED" direction
with maximum force.
Function disabled
OFF
POTENTIOMETER
PT1 (TRIMMING POTENTIOMETER 1): BIPART DELAY
Controls the bipart delay if wings overlap. For OPEN = 0 or 3 sec. For
CLOSED = 0-20 sec. Motor 1 (master) is opened first and closed last.
It is necessary that the bipart delay is always set so that nobody is
caught between the wings when they close. Left stop: Bipart delay
OFF
PT2 (TRIMMING POTENTIOMETER 2): AUTOMATIC CLOSING
(TIMER TO CLOSE)
The waiting time for the gate for GATE OPEN can be defined. The
gate is closed 0-150 sec. after the set time expires. Only working
with failsafe photocell(s) 771E installed.
Left stop: Automatic closing OFF
The control board complies with the latest EU guidelines.
One of these guidelines specifies that the closing forces at the gate
edge must not exceed 400 N (40 kg) for the last 500 mm before the
door is CLOSED. Above 500 mm, the maximum force at the gate
edge must not exceed 1400 N (140 kg). If this cannot be ensured, a
contact strip must be mounted on the gate at a height up to 2.5 m or
on the opposite pillar (EN12453).
PT3 (TRIMMING POTENTIOMETER 3): FORCE SETTING (FORCE
1 MASTER)
Definition of the force with which motor 1 = master is to operate. The
required force depends on weight and function of the gate.
PT4 (TRIMMING POTENTIOMETER 4): FORCE SETTING (FORCE
2 SECOND)
Definition of the force with which motor 2 = second is to operate. The
required force depends on weight and function of the gate.
