PROGRAMS
The control unit provides 4 operating modes (programs). The desired
program is set by means of DIP switches 1+2.
Standard (step by step):
DIP switch 1 OFF
DIP switch 2 ON
The gate is not closed automatically. Trimming potentiometer B has
no effect. The light barrier reverses the gate to "open" when it closes.
If there is a requirement for the light barrier to also be active in the
OPEN direction, it must be connected to contact 11+12 (Stop).
Automatic:
DIP switch 1 OFF
DIP switch 2 OFF
After the gate has completely opened, it is automatically closed after
the preset time (Pause, trimming potentiometer B). The light barrier
reverses the gate OPEN when it closes. If the light barrier is broken
in the gate open position, the preset pause is extended.
Automatic (fast closing):
DIP switch 1 ON
DIP switch 2 OFF
If the control unit receives a pulse from a handset or switch when the
gate is opening, the gate is immediately closed. If the light barrier is
interrupted while the gate is open, the preset pause is shortened and
the gate closes immediately (otherwise operation is same as for
2B
automatic mode).
Dead man's operation:
2B
DIP switch 4 ON
A key-operated switch or handset must be used to continuously send
a signal to the control unit in order to operate the gate. If the signal
stops, the gate comes to a standstill and its direction of movement is
changed when the next signal is received. This mode must always be
used if the gate does not have the necessary safety devices in
accordance with the regulations or if the light barrier is not working.
SETTINGS
Once you have decided on a program, the potentiometers must be
set.
Potentiometer A
Specify the force which the motor is to develop. The required force
depends on the weight and function of the gate.
The force exerted by the edge of the gate as it closes must not
exceed 400 N. If the closing force is set so that it exceeds 400 N,
the light barrier must be installed.
Trimming capacitor B Pause (pause time in the open position)
If the automatic or automatic with STOP program is set, the pause
time of the gate when the GATE OPENS must be specified. Once the
preset time has elapsed, the gate is closed.
Trimming capacitor C Brake
Once the gate reaches the limit switch it switches off. Depending on
the weight and function of the gate it carries on moving slightly due to
inertia. The brake function can be used to actively brake the gate,
thus minimising any unwanted overtravel. Left-hand end stop = brake
OFF.
