connection
Note that the triac outputs must not be connected directly to the sunblind control
motor. They are low-power, low-voltage outputs. Consult the sunblind power control
unit manual if you want to connect US100 to the sunblind control unit. Use
ME200
, the
relay power module, to control the sunblind motors directly.
DIP switches
Back of the PCB
BUS END:
if ON, the bus is terminated (if
last device on the line)
USR:
not used, reserved for future
applications
INIT:
sets the controller into default
state and sets bus address to 1, baud rate
to 9600. To init, proceed as follows:
- connect the device over RS485 to a PC
with ModComTool config tool
- set INIT to ON
- apply power (use only the connector
without bottom)
- find the controller in the tool (Scan)
- set INIT to OFF
- in the
ModComTool
tool, open the
controller window
- click the Init button in the tool
- remove and apply power.
Installation
Units are intended for operating in a normal and chemically non-aggressive
environment. They do not need any servicing or maintenance. Install them in a vertical
position at places where they can be operated easily and measure correct values of
temperature, i.e. in the height of about 150 cm, with no direct sunlight or other heat /
cool source (AHU outlets, refridgerator, electrical appliances). The device consists of
two parts: bottom with screw terminal block and cover containing PCB, display, and the
knob. The bottom part is fixed by 2 or 4 screws to any flat surface or a flush-mounting
box Ø 50 mm. At the back of the bottom there is an aperture for cabling. The bottom
