Special connections
Control output (0 – 10V / PWM)
These outputs are intended for the speed control of electronic pumps, for control of burner
performance (0 - 10V or PWM) or for switching the auxiliary relay HIREL-STAG. They can be
operated via respective menu functions parallel to the other outputs A1 to A3.
Sensor input S6
As transducer in the menu SENSOR, all of the six input can work as digital inputs. Unlike
the other inputs, input S6 has the special ability of being able to detect quick signal changes,
such as those from volume flow encoders (type VSG...).
The data link (DL-Bus)
The bi-directional data link (DL-Bus) was developed for the ESR/UVR series and is
only compatible with products of the Technische Alternative company.
Any cable with a cross
section of 0.75 mm² can be used for the data link (e.g. twin-strand) having a max. length of
30 m. For longer cables, we recommend the use of shielded cable.
Interface to PC:
The data is cached via the data converter
D-LOGG
, Bootloader
BL-NET
or
C.M.I.
interface and transferred to the PC on request.
BL-NET
and
C.M.I.
require a separate
12V power unit for power supply.
External sensors:
Reading the values from external sensors with DL connector.
Switch output 3 to potential-free
By removing the jumper
J
the relay output A3 can be made potential-free.
With the jumper
J
in place, output 3 is
not
potential-free.
Example
: Connection of a pump
L ...
Phase conductor (line)
NO .... Closer (make contact)
NC .... Opener (break contact)
If the jumper is removed, then output 3 is
potential-free.
Example
: burner requirement
C ....
Root
NO .... Closer (make contact)
NC .... Opener (break contact)
