4 Installation and start-up VDD 500
Case controller UA 4xx E commissioning
Switch off controller, disconnect from the power supply (A).
Activate DISPLAY interface for the communication with VDD 500:
Set DIP switch 7 to ON
(B).
Connect temperature displays VDD 500 to the DISPLAY interface (C),
for details about the wiring, see chapter
Connection - Terminal assignment VDD 500
.
Switch on the controller again, supply with power (A).
All temperature displays VDD 500 connected to the case controller display their address (e.g. "A09")
continuously, as no temperature sensors have been assigned to them yet.
Note:
The displayed address corresponds to the last two digits of the serial number of the respective
temperature display.
Integrate temperature displays VDD 500:
- first call up the terminal mode of the desired case controller via the system centre (E) connected via the
CAN bus (D),
- start the search via the "VDD scan" parameter in menu 6-1 and determine the number of connected
temperature displays.
Note
:
The VDD Scan parameter is only visible if DIP switch 7 is set to ON!
- The addresses (e.g. "A09") flash in the display during the VDD scan.
DANGER
Warning about dangerous electrical voltage!
Danger to life - Danger of electric shock! BEFORE
connecting and disconnecting, it must be
checked that
no voltage
is present at all connections of the controller.
The temperature displays VDD 500 are
only
compatible with case controllers with
9-pole DIP switch
(B) and version
V3.20 or higher
, the current firmware for the UA 4xx E is available in the EDP. The
temperature displays VDD 500 can
only
be configured using a system centre (E) connected on the
CAN bus!
