Range of functions
The contact switches for example in case of negative compensation power,
if no line is available for switching off and the trend power is higher than the
target value.
The hysteresis for switching off is always 10 sec, there is no hysteresis for
switching on.
The maximum prewarning contact is activated by assigning the virtual output
A48 to a relay output.
2.8
Power measurement by means of energy pulses
of the energy supplier
The
multimax
can be adapted to the conditions of the energy supplier. Energy
proportional energy pulses are required as characteristic quantity for the
power. They are either supplied by the grid operator or created with a pulse
generator/counter. The actual power for trend calculation is continuously deter-
mined via pulse period measurement and pulse count.
2.9
Counter pulse monitoring
In case the pulses are interrupted, a central error message system can be
activated by means of the error message contact.
2.10
Measuring period synchronization by energy supplier pulse
A measuring period synchronous pulse provides for synchronicity of the
measuring periods from energy supplier and energy control system. It is usually
supplied by the respective energy supplier. If there is no synchronous pulse, the
system will generate the measuring period time itself. In a combined system,
synchronization will likely be triggered by the eBus Master.
2.11
3 target values for consumption limits
3 individually programmable target values for power are available. Switching
between the target values is realized by means of floating contacts
(e.g. by the energy supplier).
