6.2.5 Toggle impulse key
How to connect a key to input "In4" and configure it is described below. Whenever
this key is pressed, an impulse is generated for the toggle functions OPEN, STOP,
CLOSE, STOP.
Here, the input "In4" has already been factory-configured for the relevant
function. The function at this input is only supported in automatic mode. Contacts
can also be connected to the backplane; see appendix B and C.
•
Switch off the power supply to the motor drive.
•
Connect the key to the 24V power supply.
•
Connect the key for the toggle impulse to input terminal In4
(make contact ).
•
Switch on the power supply of the motor drive.
Check that the key works.
6.2.6 Installing/Setting a part open function
To set a part open function, a pushbutton or switch contact (make contact) is
connected to input In5. Contacts can also be connected to the backplane; see
appendix B and C.
• Switch off the power supply to the motor drive.
•
Connect the key/switch to the 24V power supply.
•
Connect the key/switch to input In5.
•
Switch on the power supply of the motor drive.
•
Check that the part open function of the gate works.
The opening width of the gate from the CLOSED position to the partial OPEN OPEN
position is determined by the value of the incremental encoder. How this is set is
described in chapter 7.3.
6.2.7 Connecting the status indicator of the gate
The HMD230 can indicate two different gate statuses by means of relays. The
output relay "Rel2" is factory-set such that it is closed when the gate has reached
its OPEN position. The output relay "Rel3" has been set such that it is closed when
the "gate CLOSED" position has been reached. No further settings are required.
Contacts can also be connected to the backplane; see appendix B and C.
