Setting of limit for load sensor (C30,C31)
1. Press the ↵ key so that the display shows the channel number (C to extreme left).
2. Step using the + key or the – key until C30 appears (load limit, motor 1).
3. Press the ↵ key. The value appears in the display.
4. Press the + key. The value starts to flash.
5. Step using the + key or the – key until the value you wish to set appears (normally a value about
0.10 units higher than the highest value read off).
6. Press the ↵ key. The value is saved.
7. If there are two motors, repeat items 1-4 for motor 2 with C31 (load limit, motor 2).
NB:
If there is a risk of gate judder or swaying, the control panel may register this as a load. Test this by
reading the load and starting the gate from slightly different positions. There is an adjustable time
delay that blocks the load sensor during start. If the gate has a long starting time or judders several
times during starting, it may need to be raised.
The load may also rise when the gate reaches the nearly-closed position and compresses the rubber
buffers. If necessary, re-adjust the limit switch cam position and arm length, so that the right pressure
is obtained in closed position.
Motor protection (C44 & C45)
Protection is set so that it trips out when the motor is drawing too much current. The built-in motor
protector measures the current of phase L1. The motor is protected if any phase disappears and the
motor draws too much current. If no current is obtained in phase L1, the gate is stopped and an error
message appears. If the electric motor is seized it also draws a lot of current and the protector trips
out. An error message appears when the motor protector has tripped out and the motor stops
immediately. Motor protection must be reset on C44 (motor 1) and C45 (motor 2) when using 3x230 V
or single phase.
Start settings: 3x230 V=1,8A. Single phase =2,0A.
Limited running time
There is a running time limit device to protect the equipment against possible faults. This time should
be set longer than the normal operating time if error protection is to function.
• In the case of deadman control, there is no limited running time, and time measurement may be
carried out without the gate being stopped prematurely if the set running time is exceeded.
Measurement of running time (C11,C12)
1. Step to C11(running time, motor 1).
2. Read and note the running time for motor 1. Reading should take place from fully closed to fully
open or the other way round.
3. Step to the channel for motor 2.
4. If there are two motors, repeat for motor 2 (C12, running time, motor 2).
Setting limited running time (C32)
1. Step to C32 for setting of limited running time.
2. Set 3 seconds longer than the longest measured time.
