GD connected to
Danfoss monitoring
Danfoss offers the possibility of connecting every GD,
independent of model, via the built-in RS 485 Bus
communication, directly to the Danfoss monitoring
unit.
Up to 31 GD sensors can be connected via a two-
core screened communication cable (see the below
drawing).
Every GD sensor needs a unique address number which
must be selected. The address of GD is set by S2 and
S3. By setting S2 and S3 between 0 and F, the GD will be
assigned an address. See next page.
A conversion chart between channel number of the
Danfoss monitoring system and the hexadecimal
address of the GD is attached. Power must be removed
when setting the addresses on the GD sensor.
If more than 31 units are needed, a GD Repeater
(amplifier) must be installed (see Accessories).
Contact Danfoss for further information.
