Specification of the eBus address is queried in the
commissioning program.
Each station needs to be assigned a unique number under
KOM04
EBUS AD-DRESS
. Any numbers between 2 and 16 can be chosen.
The assigned eBus addresses in adjusters
STN1…5 EBUS MASTER
NUMBER
need to be saved in the controller of the master station. No
more than 5 stations can therefore be combined in a cascade.
Example:
1st station (Master)
STN eBUS MASTER NUMBER = 2
2nd station (Slave 1)
STN eBUS MASTER NUMBER = 3
3rd station (Slave 2)
STN eBUS MASTER NUMBER = 4
4th station (no station)
STN eBUS MASTER NUMBER = 0
5th station (no station)
STN eBUS MASTER NUMBER = 0
A sequential changeover occurs at midnight each day which ensures
equal usage of the stations. With regard to the changeover, the
sequence of the connection of stations is changed in each case. The
changeover occurs as soon as no further tapping is taking place. With
regard to continuous tapping, the changeover occurs no later than 2
am. Example of the connection for increasing tapping with 3 stations:
1st station 1, 2nd station 2, 3rd station 3
®
Changeover: 1st station
2, 2nd station 3, 3rd station 1.
Circulation functions can be used centrally or locally. This is defined
with the adjuster
KAS07 CIRC.PUMP CAS. CENTRAL
.
n
0: Decentralised circulation pump (at each station)
The circulation pump is integrated in one or more stations. Set-
tings for circulation and thermal disinfection are made at the sta-
tions with an integrated pump.
n
1: Central circulation pump (at the master).
The circulation pump is installed outside of the stations and is
connected to the master station. Settings for circulation and
thermal disinfection are only made at the master station.
6.10.2
Options in the cascade
The circulation pump is connected to the master station. All settings
for circulation mode and thermal disinfection are made at the master
for the entire cascade.
