DAAB COMMUNICATION CARD DB408 INSTRUCTION MANUAL

Functions using add-in card DB408
Two EP104s can send interlocks and start signals between each other through communication. Each of the doors must first be
commissioned and tested locally in accordance with the the DAAB Automatic Control Unit EP104 instruction manual. The
terms local door and remote door are used in the text. The local door is the door currently being configured. The remote door
is the door connected to the local door via the communication cable.
Communication
To pass signals and values from one EP104 to another configure C695. If C695 = 0, the communication is disabled.
Always start by setting C695=2 in one of the units, then start communication by setting C695=1 in the other unit. The
automatic control unit with C695=1 immediately starts transmitting values to the automatic control unit with C695=2,
which responds by returning the values. If communication fails, the error message E614 appears in the display. This error
message means that the automatic control unit with C695=1 does not receive a response to transmitted messages. Possible
causes: only one of the automatic control units is configured for communication; C695 is set to the same value in both
units; or one of the units is switched off. To acknowledge the error message, press any programming button. The error
message continues to appear for as long as the transmitting automatic control unit does not receive a response.
Blocking of remote door (C664)
The opening and closing function of the remote door is blocked by the position of the local door under the conditions
specified for the channel. The setting 0 gives no blocking the value 1 gives blocking of opening of the local door until the
remote door is closed. See the channel reference for more configuration options.
Opening memory, cancel block with stop (C665)
When the interlock and blocking function between two doors is used, the remote door is operated using a programmable
input or opening function via the vehicle detector DB402 or the radio card DB411. For programmable input, opening of
remote door is configured in channels P190-P690; for the vehicle detector in channels d190 and d290 and for the radio card
in channels r190 to r90. Opening memory means that the local door remembers the open signal that was sent, even though
it must stay closed until the remote door has reached the open position – the function can be configured in channel C665.
With the setting 0, the local door does not remember the open signal, and a stop signal does not cancel a block. If you
set the value to 1 the local door will remember the open signal without the stop signal cancelling a block. See the channel
reference for more configuration options. Block is cancelled by the stop circuit being broken for at least 5 seconds, after
which the block is cancelled.
Example applications
Examples of some systems with interlock system are described below. Each new example is highlighted in
bold
.
Opening two doors simultaneously:
To open two adjacent doors at the same time, activate a programmable input, e.g. INP1 for interlock opening. P160 = 1
means that the local door opens and P190 = 1 means that the open command is transmitted to the remote door. If C664
is set to 0, the signal is sent directly to the remote door. If it is set to 1, the signal is not passed on until after the local door
has opened and then closed.
Preventing draughts in spaces with two doors, thermal interlock
If there is a problem with draughts, doors can be blocked so that only one can be opened at a time. The door will not open
before the other linked door is closed. The software remembers the most recent opening operation, so the door will be
opened once the other door closes, even if it is currently blocked from opening because the other door is opening or is
open. The memory function can be disabled in channel C655.
Configuration for the above example with programmable input INP1:
•
Door 1, C664 = 1, P160 = 1, P190 = 1, C500/C501 = suitable automatic closing time.
•
Door 2, C664 = 1, P160 = 1, P190 = 1, C500/C501 = suitable automatic closing time.
Directional thermal interlock
A thermal interlock can also be directional – in other words the interlock works from one direction but not the other.
Example: When door 1 is operated using the programmable input, door 1 opens and then closes using the automatic
closing time, then door 2 opens automatically and closes using the automatic closing time. When approached from the
other direction, however, doors 1 and 2 open at the same time.
Configuration for the above example with programmable input INP1:
•
Door 1, C664 = 0, P190 = 1.
•
Door 2, C664 = 1, P190 = 1, P196 = 1.
