OPERATION
MONITORING LEDS
There are six monitoring LEDs which can be used for troubleshooting
or functional testing.
LED 1
Yellow
LIT = emergency stop free or
jumper fitted.
LED 2
Green
LIT = signal from switch or radio
is present (open gate
completely).
LED 3
Green
LIT = signal from switch or radio
is present (open gate
partially).
LED 4
Red
LIT = light barrier(s) free or
jumper fitted.
LED 5
Red
LIT = OPEN limit switch
activated
LED 6
Red
LIT = CLOSE limit switch
activated
LED 7
Red
Flashes slowly =
OK
Flashes fast =
Connection error and/or short
circuit in 230 V circuitry.
Both limit switches are
ACTIVATED simultaneously!
LED 9 – 10
It is possible to connect a gate
status LED. This indicates the
status of the gate.
OFF
= gate closed
Flashes slowly
= gate opening
LIT
= gate opened
Flashes fast
= gate closing
FUSES
F1
3.15A, 250V
Main fuse
Protects control
unit/transformer/flashing lamp/motor in
the event of a short-circuit
F2
0.5A, 250V
24 V AC supply
Trips in the event of a short-circuit or
overload on terminals 20-21
F3
0.315A, 250V
Logic circuitry fuse
Buttons, emergency stop, light barrier,
receiver
Never use fuses with a higher rating than the specified rating!
INITIAL OPERATION
BASIC SETTINGS
(1)
Connect the drive in accordance with the enclosed connection
instructions.
(2)
Move the gate to the half opened position and latch the motor.
(3)
Make the following basic settings on the motor control unit:
A
- Set force to 30%
B
- Deactivate automatic closing
(set DIP switch 1 to OFF and 2 to ON)
.
C
- Set travel time to 30%.
(4)
Switch on the 230 V power supply.
(5)
Start the motor control unit by pressing the test button; the gate
must open. If the gate closes, swap the connections of the +
motor leads on the limit switches (4 + 6).
It is vital to switch off the mains supply before swapping the lead
connections round!
(6)
Repeat steps 2 and 5 until the required operation is obtained.
(7)
Use
potentiometer C
to adjust the travel time. It is advisable to
set the travel time to roughly 2 to 3 seconds longer than required
in order to open and close the gate.
(8)
Use
potentiometer A
to adjust the force developed by the
motors so that it is just enough to open and close the gate
properly.
(9)
Test gate operation over several complete cycles to see how the
gate operates and observe whether or not switch-off occurs
when it reaches the limit switches.
(10)
Test the functioning of the light barrier.
(11)
If you prefer a different program (automatic closing), do not set
this program until the final step. Please read the effects which
this gate program has on operation.
