MASTER / SLAVE conguration
When more controllers are
connected via CAN bus each

If the system capacity requires more than one
control valve; up to three valves can be
controlled simultaneously in a Master/Slave
conguration, where the master and each slave
controls one valve respectively.
The conguration is programmed in the master
EKE 347 IO cong menu - Multiple valve
setup - with one of these options:
• 2 valves with same capacity
• 2 valves with dierent capacity
• 3 valves with same capacity
• 3 valves with dierent capacity
Multivalve Additionally the master must be programmed
in IO cong menu - Multiple valve pattern - for
either:
• Valves in parallel
(valves regulate simultaneously)
or
• Valves sequential
(mainly one valve regulating at any time)
See principle below.
The slave EKE’s only need identication of Slave
and valve CAN ID (communication menu).
The default display of the master EKE will show
the standard information together with a symbol
of multiple valves and the actual total opening
degree (see below).
The default display of the slave EKE will show the
actual liquid level (as the master), symbol of
multiple valves, actual total opening degree and
the opening degree of the individual valves
involved (see below).
