4.6.3 Connection of the temperature
sensor(s)
If a 2nd temperature sensor is used, this is to
be connected to the extension board or to
relay board 1 (if several relay boards are
present):
4.6.4 Connecting the digital input (DI)
The digital input on the mainboard can be
used for switching functions.
The digital input must be wired on-site in
accordance with its use, e.g. with as push-
button or a switch (also see chapter 6.8.8
„Function parameters“ / „Function_digital_
input“).
Wiring the digital input (DI) :
4.6.5 Connection of the control sig-
nal and the release signal in
case of multiple units
In case of multiple units, separate steam gen-
erators work together. The control signal and
the release signal are connected to the mas-
ter unit, as described above. In addition, con-
necting cables are established between the
master unit and the slave unit(s) (provided
on-site). This is used by the master unit to
provide the slave unit with an actuator signal
and the transmitted (potential free) release
signal.
The electrical connection for the control sig-
nal and release signal must be implemented
as follows for multiple units:
1)
„ST07“ designates the connector plug on the main-
board
2)
„K20“ is the relay used for the connection of the suc-
cessing unit with the installed option (CN-07-10012) or
the enclosed option (CN-07-10002)
