2 Range of Functions
The multimax D6-xxx-5 energy control system can signicantly contribute to lowering
commercial energy costs.
2.1 Monitoring Energy Consumption
The peak power is an important cost factor for special tari devices.
The multimax D6-xxx-5 ensures optimum distribution of available power and helps pre-
vent expensive power peaks by means of intelligent monitoring of energy consumption.
2.2 Energy Optimization with Trend Calculation
The multimax D6-xxx-5 works as an optimization calculator, taking into account the
assumed further energy consumption within the measurement period. To avoid unnec-
essary shutdown, careful adjustments are made to the energy consumption in consider-
ation of the device properties:
2.3 Switching Devices On or O Using Compensation Power
Negative compensation power switches devices o and positive compensation power
switches them on. Compensation power is the result of the comparison of the trend
power with the rated power taking into account the available consumer power.
2.4 Switching Devices O Via Relay Outputs
The basic module features 5 non-oating relay contacts to
switch o the devices participating in optimization.
Using 4-stage additional components, up to 32 switching outputs can be
implemented (see “Connecting Additional Modules”).
NO or NC contact functions can be programmed to switch o the
devices.
2.4.1 Device Regulation via
Analog Output Module multisio D2-2AO-1
For devices that can be regulated continuously via an analog input (0–10 V/0–20 mA),
there is an analog output module available.
This ensures that power consumption is fully and continuously exploited
(the trend power always corresponds to the target period value).
Range of Functions

V5.00

2.4.2 Digital Output
The basic module of the multimax load management system features a digital output
(I/O – parameter M00.12, please ensure correct polarity!) with a freely assignable output
address. This means that devices, which feature a digital input (S0compatible), can be
controlled directly. Furthermore, the current state of a device can be visualized, e.g. by
connecting a digital output to a BMS.
By assigning a digital output to the prewarning contact (A 48), its status can be estab-
lished, e.g. through a control light with a digital control input.
Using the additional module multisio-4DO, this functionality can be extended by
4 digital outputs.
2.4.3 Decentralization Using Substations
The multimax energy control system and its central system can be expanded
using substations. Communication is carried out via
a bus line.

Range of Functions
2.5 Recording States Using Message Modules
By determining the state of the optimizable devices, the optimization action can be con-
trolled. A message input can be associated to every output.
In addition to the digital input module inputs (for oating switches or electronic switches
(ensure correct polarity)), the voltage inputs of the
multimess D4-xxx-1 measuring module can also be used as message inputs. This module
enables 230 VAC feedback (e.g. directly from the device main switch) to be evaluated,
whereby an input voltage of > 70 VAC is evaluated as an on state.
The multimax 4 load management system receives important information about each
device via the message inputs. In this way, it can be established whether
the device is reported as optimizable via the input
the device is reported as inactive
The following are also possible:
External device control (permanently switched on (Manual_On) or permanently
switched o (Manual_O ))
Changing line priority
In the case of running timer programs, there is an additional option to
modify the process and inuence the state of the optimization lines:
Emergency_On (switches on the line in case of emergency)
Emergency_O (switches o the line in case of emergency)
Starting a generator (CHP)
Default as contact (when active)
The contact switches, for example when the compensation power is negative, if there is
no longer any line to switch o and the trend power is greater than the target value.
The hysteresis for switching back is xed at 10 seconds; there is no hysteresis for switch-
ing on.
The maximum prewarning contact is activated through the assignment of the virtual
output A48 to a relay output.

Range of Functions
2.6 Power Measurement Using Energy Pulses from the Energy Supplier
The multimax can be adapted to the energy supplier conditions. Energy proportional en-
ergy pulses are required as characteristic quantity for the power. They are either provided
by the network operator or created by a pulse generator/counter. The instantaneous
power for trend calculation is continuously determined via pulse period measurement
and pulse count.
2.7 Meter Pulse Monitoring
In case the pulses are interrupted, a central error message system can be activated by
means of the error message contacts.
2.8 Recording Current Power
If the electricity supplier is not able to provide an energy pulse, you have the option of
implementing the instantaneous operating reference power via a voltage and current
measurement (active power reference), using a multimess D4-1.
The multimess D4-1 measuring module has three measuring channels whose measured
values can be further processed directly as power values. The fourth channel relays the
total value of the three measuring channels. This means that four power values are pro-
vided.
I/O parameters of channels 1 to 4:
Channels 1, 2 and 3 (single channel):
Channel name
Primary transformer voltage value
Secondary transformer voltage value
Primary transformer current
Secondary transformer current
Measurement type: consumption or recovery
Single or three-phase power measurement
Channel 4 (mixed channel):
Channel name
Primary transformer voltage value (taken from channels 1 to 3)
Secondary transformer voltage value (taken from channels 1 to 3)
Primary transformer current value (taken from channels 1 to 3)
Secondary transformer current value (taken from channels 1 to 3)
Measurement type: consumption or recovery

V5.00
25832_EDEBDA0289-5020-1_EN
14
Range of Functions
Channels 1, 2 and 3 (single channel):
If set to single phase, only the measured value of this channel will be relayed as current
power.
If set to three-phrase, the measured value of the channel is extrapolated to a three-phase
measurement and relayed as the total current power. The output value of channel 4
would then correspond to the sum of three three-phase measurements.
For three-phase measurements, either measuring channels 1, 2 and 3 can be used as
three dierent meter inputs or channel 4 can be used exclusively as a single mixed chan-
nel.
However, the measuring mode of each individual channel must be set to single phase.
Meter Pulse Monitoring:
Meter pulse monitoring can only be used to monitor digital inputs.
However, the multimess D4-1 provides an analog measured value.
2.9 Measurement Period Synchronization Using an Energy Supplier
Pulse
A measurement period synchronized pulse provides for synchronicity of the measure-
ment periods from energy supplier and energy control system. This pulse is generally pro-
vided by the network operator. If there is no synchronized pulse, the device will generate
the measurement period time itself. In the overall system, synchronization is generally
performed by the eBus master.
2.10 3 Target Values for Consumption Limits
3 individually programmable rated values for power are available. Switching between the
rated values is realized by means of oating contacts (e.g. by the energy supplier). The
switching of target values can either be performed using internal timer programs or a
target value list.

5 Device Memory
Non-volatile long-term memory
The device is equipped with an internal, non-volatile memory in which long-term data is
stored.
Buered real-time clock (RTC)
After an uninterrupted charging time (device connected to the supply voltage) of approx.
8 hours, the buer capacitor will have a sucient charge to protect the internal clock
from failure due to lack of operating voltage for approx. 14 days.
NOTE
If the buer capacitor is discharged and there is no supply voltage, once the device has
been switched on, the time settings will be incorrect and must therefore be reset!
