Description of function, d-channels
Two vehicle loops can be connected to the automatic control units via DB402 add-in cards – to activate the inputs set channels
d100 and/or d200 to the value 1. When the unit is delivered and following a reset, channels d100 and d200 are set to 0,
disabled. The settings below apply to vehicle loop 1, using channel numbers d101 – d190. The functions are the same for
vehicle loop 2, except that the channels are numbered d201 – d290. See the channel reference.
Configuring the vehicle loop
Activate the vehicle loop inputs by setting channel d100 to 1.
Channels d101, d102 and d103 are used for loop readouts, and channels d110 to d195 are all used to change settings.
The value in channel d102 must be between 08 and 50, otherwise the vehicle loop will not work correctly.
Basic settings for the vehicle loop:
•
Detection limit
Set the value in channel d110 to detect vehicles on the vehicle loop.
Set the difference between on and off in channel d111
•
Vehicle loop reset
There are two channels you can use to reset presence on the vehicle loop – d121 for times between 00 – 99 seconds and
d120 for longer times between 005 – 240 minutes.
The timer starts when the vehicle loop is activated, and the loop is reset even if there is still a signal at the loop when the
timer ends.
•
Compensation for door halves
These channel are used if the door halves activate the loops as they open or close. Open and close the door – the readout in
channel d103 indicates the time of loop activation. Enter the time and increase it until the door no longer activates the loop,
using channel d131 for the door half operated by motor 1 and d132 for the door half operated by motor 2.
Vehicle loop functions
A number of functions are available when a vehicle loop is activated, using the following channels:
d151, Loop-based closing
Use can use this channel to activate loop-based closing. The value 1 activates loop-based closing and 0 deactivates loop-
based closing.
d154, Type of loop closing
This channel works with d151 to control the function of loop-based closing. Either the door closes as soon as the vehicle
loop is no longer activated (option 1), or it is left to open fully before closing (option 2).
P160, Control function
This channel is used to enable the opening function with the vehicle loop. The value 0 disables the opening function, and
the value 1 activates it.
d161, Type of control signal.
This channel works with d160 and determines the type of the open signal from the vehicle loop – either a pulse (option 0)
or a constant signal while the vehicle loop is activated (option 1).
d162, Half operation
This channel defines which motor will be opened by the vehicle loop. The value 1 opens motor 1, 2 opens motor 2, and 3
opens both motors 1 and 2.
d163, Limited opening
EP104
:
If you want limited opening, set this channel to the value 1, the door will then open according to the set time in C412 and
C414 when a limit switch is used or a specified number of degrees in L116 and L126 when an encoder is used.
EP105
:
If you want limited opening, set this channel to the value 1, the door will then open according to the set time in C216 and
L226 when a limit switch is used or a specified number of degrees in L116 and L126 when an encoder is used.
d170, Enable operation from a programmable input
This channel allows you to disable the opening function from a programmable input. Make sure that the programmable
input is active and that all the settings have been disabled. The opening function of the vehicle loop will work for as long as
there is a signal present at the programmable input specified in this channel.
d175, Delayed opening
This channel delays the open signal, for example to ensure that the door is not opened by passing cars that are not heading
for the door. The channel is set to the number of seconds you want to delay the open signal.
d190, Interlock, Used to send interlock opening to remote door.
