EMERGENCY STOP (OPTIONAL)
If a switch can be connected the system can be stopped or blocked. Any
movement of the leaf is then immediately interrupted. According to the
level of safety required on the door the contact can also be connected to
the photocell contacts. This causes any leaf movement to stop
immediately.
Cable cross-section: 0.5 mm 2
Voltage: 12/24 Volt AC/DC
Do not use rigid copper wires. Do not lay 230 Volt cables in parallel or in
the same channel.
FLASHING LAMP (OPTIONAL)
A flashing lamp can be connected to the controller. It warns people of
the moving door. The flashing lamp should be fitted as high and as
visible as possible. The controller gives a constant signal which is
converted by the lamp into flashing (Fig. 10+11).
Cable cross-section: 0.5 mm 2
Voltage: 230V 40W
Do not use rigid copper wires. Do not lay 230 Volt cables in parallel or in
the same channel.
ELECTRICAL LOCK (OPTIONAL)
An electrical lock can be connected to the controller via the plug CN4.
An additional small relay controller, which can be obtained, is clamped
between the drive electronics and the elect. lock.
Cable cross-section: 0.5 mm 2
Voltage: 12/24 Volt AC/DC
Do not use rigid copper wires. Do not lay 230 Volt cables in parallel or in
the same channel.
KEY SWITCH (OPTIONAL)
On the plexiglass cover there is a built-in switch (only BAS300K). This
switch opens or closes the door at the press of a button. It is solid wired
to the input St.1 for normal operation.
The controller/drive can be activated by different inputs. These can be
initiated by hand transmitter or key switch.
• Hand transmitter = see section "Hand transmitter teach-in"
• Switch input 1 = input St.1, normal operation
• Switch input 2 = input St.2, active at special settings (see DIP switch
SW2, Dip1 + Dip2)
DESCRIPTION OF POTENTIOMETER
The potentiometers are positioned in the middle of the controller and are
arranged beside one another. Their values can be changed by means of
a small screwdriver. Warning, turn carefully so that the component is not
overwound. Turning clockwise increases the setting values (Fig. 5).
The maximum running time of the controller is fixed at 40 seconds.
Potentiometers
OPEN Controls the force for the opening movement
CLOSE Controls the force for the closing movement
RPM Potentiometer for regulating the sensitivity of the
speed sensor:
It controls the necessary time between 0-2s. Before
reversing the operating direction 2s, then it stops.
Only active if the RPM sensor is installed. The
speed sensor should always be set to be as
sensitive as possible. Speed sensor: Plug CN3 on
the controller.

DESCRIPTION OF POTENTIOMETER (CONTINUED)
The force, as measured on the closing edge of the door, should not
exceed 150N (15kg). If the closing force is adjusted to more than
150N, The Protector System™ must be installed.
Do not use force adjustments to compensate for a binding or
sticking garage door. Excessive force will interfere with proper
operation of the safety reverse system or damage the door.
Force Adjustment Controls are located on the control panel.
If the force adjustments are set too light, door travel may be interrupted
by nuisance reversals in down direction and stops in up direction.
Weather conditions can affect the door movement, occasional
adjustment may be needed.
Maximum force adjustment range is 260 degrees, about 3/4 of a
complete turn. Do not force controls beyond that point. Turn force
adjustment controls with a screwdriver.
Test Down (Close) Force: Grasp the door handle or door bottom when
door is about halfway through down (close) travel. Door should reverse.
Reversal halfway through down travel does not guarantee reversal on a
50mm obstruction.
If the door is hard to hold or doesn't reverse, decrease down
(close) force by turning the control in a counterclockwise direction.
Make small adjustments until door reverses normally. After each
adjustment, run opener through a complete cycle.
DIP SWITCHES
Different programmes can be selected by means of the dip switches. It
is advisable to only change the dip switches after completing the
installation and to leave them at the factory setting for initial
commissioning. To activate a new function the drive must be briefly
isolated from the mains (Fig. 5).
On = Push switch to "ON" position
Switchblock SW1 = Lower red switchblock
Switches 1+2
General setting of automatic operating logic – with automatic or manual
closing. Only with connected and non-blocking failsafe photocell with
pulsating signal (2-cable photocell).
No 1 No 2
on on Automatic with 90 sec. pause in opening
off on Automatic with 60 sec. pause in opening
on off Automatic with 30 sec. pause in opening
off off Manual operation = factory setting
Switches 3+4
Define the reaction of the drive when the limit switch is reached. A
change in the factory setting is only necessary if for example the door
cannot be completely closed. If the factory setting is changed the "close"
limit switch must also be changed (beforehand), because the drive
continues for 5 seconds after the limit switch has been reached (approx.
30-45°).
