• Pulse mode and hold-to-run mode
Hold-to-run mode means that the button has to be kept pressed to open or close – when the button is released, the motor
stops.
In pulse mode, pressing and releasing the button opens or closes the door automatically. Pulse mode can be configured for
either direction. Pulse mode must be active for automatic operation of the door.
Note that the applicable directive does not allow wireless transmitters to operate in hold-to-run mode, and wireless transmitters
therefore do not work in hold-to-run mode. Pulse mode always applies with wireless transmitters.
Selecting pulse mode or hold-to-run mode
Select channel C033 and set the function you want.
Example 1:
To set pulse mode for both opening and closing movements, set the value to 3.
Example 2:
To set pulse mode for the opening movement and hold-to-run mode for the closing movement, set the
value to 1.
Example 3:
Set value 5 to put the automatic control unit into service mode. This means that no external control signals
can be used. This results in safer working, as the system cannot be operated in any other way than with the
card's internal buttons. It is also used for force-run without a functioning limit switch or encoder. Only
hold-to-run works in this mode. Either L001 or L003 must be set to 4 in this mode. If encoder is used,
L110 and L120 must also be selected for the display in L111 and L121 to be correct.
Hold-to-run if there is an error in the safety edge or PHOTO input
If the safety edge, photocell or vehicle loop is faulty, the automatic control unit automatically switches to hold-to-run mode
in the direction in which there is a fault. Even when the safety edge or photocell/vehicle loop are activated, you can still
open and close the door by keeping the button on the PCB pressed As long as the control button is held down, the gate
will open or close.
• Checking safety functions
When the automatic control unit has been commissioned, all the safety functions should be checked to make sure they work
as intended. Take the motor winders into operation again by recoupling and checking the following functions:
•
Check that the safety edges work as desired, first on motor 1 and then on motor 2.
•
Check that the load guard is activated under abnormal load.
•
Check that the photocell (if there is one) is working.
•
Check that the vehicle loop (if there is one) is working.
•
If all the points above are OK, continue with commissioning. Otherwise return to the relevant section and check the
settings. If this does not help, see "Troubleshooting".
• Setting electric motor braking
This function causes the motor to change direction for a short time when the limit switch is activated, so that a direct stop is
obtained instead of slippage.
Electric motor braking only works on 3-phase motor winders and does not work on control units with a frequency converter
or single-phase motor winder. To set the control unit to this mode carry out the following:
•
Adjust encoders or limit switch cams so they match the open and closed positions of the gate.
•
Configure the braking time in C495 for motor 1 and C496 for motor 2. On light sliding gates the value should be 15-20
milliseconds. The value should be selected as low as possible, but sufficiently high for the desired braking force to be
achieved. This is to protect the mechanism in the gearbox.
