2.2 Special functions
Power measurement
The active power can be recorded in watts or kilowatts per channel and total and can be output via
object. The measured active power is the basis for monitoring load exceedances and load
undercuts, which can be further processed as 1-bit status objects. In addition to the active power,
the output of the reactive power, apparent power and the power factor cos Phi can be activated.
Current measurement
The current value can be output per channel in milliamperes or amperes. Current exceedances and
undercuts can be monitored. The thresholds, hysteresis and minimum duration of the
exceedances/undercuts are adjustable.
Voltage measurement
The voltage is output per channel as a 4-byte object. Exceedances and undercuts of a voltage
value can be monitored. The thresholds, hysteresis and minimum duration of the
exceedances/undercuts are adjustable.
Energy and cost meter/Yield meter
The balancing main and intermediate meters can be activated by channel - separately for
consumption and generation - and can be set extensively. To determine costs and yields, the
electricity and feed-in rates can either be entered as fixed values in euros or cents or transmitted as
variable values via object (day and night rates). Switching between the day and night rates can be
done via object or by time.
Events
Up to two events can be activated in each meter. An event is triggered as soon as a selected
condition is met. The condition can be a reached value of a (main) meter, certain costs of a (main)
meter, a time, or an interval. The triggered event then performs functions such as sending and/or
resetting a meter reading.
Long Frame Support
The MDT Energy Meter supports "Long Frames" (longer telegrams). These contain more user data
per telegram, which significantly reduces the programming time with the ETS.

2.5 Commissioning
After wiring the unit, the physical address is assigned, and the application is programmed:
(1) Connect the interface with the bus, e.g. MDT USB Interface.
(2) Connect mains voltage.
(3) Switch on bus voltage.
(4) Press the programming button at the device >1s (red programming LED lights).
(5) Loading of the physical address out of the ETS-Software by using the interface (red LED
goes off as soon as this process was completed successfully).
(6) Loading of the application, with requested parameterization.
(7) If the device is enabled you can test the requested functions (also possible by using the
ETS-Software).

Startup time
This time defines when the unit "boots up" after a restart (reset, reprogramming, bus voltage
recovery). This can be important if, for example, a bus reset is carried out. If there are many units
on a line, all units would start at the same time and load the bus. With a variable time, the units can
thus start differently.
„Operation“
"In operation" is used to show on the bus that the unit is "alive". If activated, an ON telegram is sent
cyclically.
Day/Night switchover
By activating the "Day/Night" object, the polarity for Day/Night can be defined in the following.
Regardless of this polarity, the unit always starts in "Day"-mode after reprogramming.
Furthermore, it can be defined whether the object is to be actively queried after a bus voltage
recovery.
Behaviour after bus power return
It can be set whether the objects for Day/Night and/or Time are to be actively queried after bus
voltage recovery.
Connection terminal channel L1 / L2 / L3 (only for EZ-0320.01)
If the lines have been incorrectly mounted at the terminals, the current direction can be reversed
with this parameter.
Current direction L1 / L2 / L3 (only for EZ-0363.01)
Depending on the mounting of the current transformer on the line, the current direction can be
reversed with this parameter.
Meter „Consumption“/“Generation“
Here you can set whether the changeover from "Day" to "Night" operation or from "Night" to "Day"
operation should take place at a fixed time (in hours and minutes) or whether the changeover is
only controlled via the "Day/Night" object.
On the other hand, it can be defined whether the meters are to be reset after programming or
whether the meter readings remain with the previous status.
Cost meter „Consumption“
When calculating costs via fixed values, the corresponding tariff for "Day" respectively "Day" and
"Night" is set in the ETS. When calculating via variable values, the tariffs are entered via objects.
The currently valid electricity price is output via object 27 - "Consumption: current electricity price".
The datapoint type for input and output can be defined via parameters.
Cost meter “Generation“
When calculating the yield via fixed values, the corresponding tariff for "Day" respectively "Day" and
"Night" is set in the ETS. When calculating via variable values, the tariffs are entered via objects.
The currently valid yield price is output via object 48 - "Generation: current yield price".
The datapoint type for input and output can be defined via parameters.
Important:
The central object 3 - "Voltage error" is permanently displayed. It only sends an alarm if the
voltage measurement is "active" in at least one menu "Consumption L1", "Consumption L2" or
"Consumption L3"!

Table 8: Settings – Total consumption: Power measurement
The active power measurement enables the output of the real active power by simultaneous
measurement of current and voltage. The output value is therefore no longer a "theoretical" power
at nominal voltage, but the actual power.
Monitoring of load exceedance
3 switching thresholds can be defined at which certain actions are carried out after the condition is
fulfilled. Switching threshold 1 is always active after activation of the monitoring. Switching
threshold 2 and/or switching threshold 3 can be activated individually.
The "Value for switching threshold" describes the value above which the selected action “Value
when exceeded” is to be carried out.
With the “Hysteresis”, the switch-off threshold can be shifted. This threshold is calculated with a
hysteresis of 10% for a load exceedance value of 100 W as follows:
Switch-on point = 100 W; reset when the load falls below 90 W (switch-on value minus hysteresis).
The "Minimum time of exceedance" indicates how long an exceedance must be measured before
the action is triggered. For example, a minimum time of 10 s for a load exceedance value of 100 W
means that a value above 100 W must be measured for 10 s before the exceedance action is
triggered. The minimum time for exceedance works together with the hysteresis. So if an
exceedance is measured, the power must fall below the set value minus hysteresis to stop the
dwell time.
The "Value on withdrawal of exceedance" triggers a defined action, which is carried out when a
load exceedance has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "value on withdrawal of exceedance"!

Monitoring of load undercut
The "Value for switching threshold" describes the value below which the selected action "Value
when undercut" is to be carried out.
The "Hysteresis" can be used to shift the switch-off threshold. This threshold is calculated with a
hysteresis of 10% for a load undercut value of 100 W as follows:
Switch-on point = 100 W; reset when 110 W is exceeded (switch-on value plus hysteresis).
The "Minimum time of undercutting" indicates how long an undercut must be measured before
the action is triggered. For example, a minimum time of 10 s for a load undercut value of 100 W
means that a value below 100 W must be measured for 10 s before the undercut action is triggered.
The minimum time for undercut works together with the hysteresis. So if an undercut is measured,
the power must rise above the set value plus hysteresis to stop the dwell time.
The "Value on withdrawal of undercut" triggers a defined action, which is executed when a load
undercut has been exceeded again.
Important: After reset/reprogramming, the value for undercut must be undercut again in order to
send the "Value on withdrawal of undercut"!

Table 12: Settings – Total generated: Power measurement
The active power measurement enables the output of the real active power by simultaneous
measurement of current and voltage. The output value is therefore no longer a "theoretical" power
at nominal voltage, but the actual power.
Monitoring of load exceedance
3 switching thresholds can be defined at which certain actions are carried out after the condition is
fulfilled. Switching threshold 1 is always active after activation of the monitoring. Switching
threshold 2 and/or switching threshold 3 can be activated individually.
The "Value for switching threshold" describes the value above which the selected action “Value
when exceeded” is to be carried out.
With the “Hysteresis”, the switch-off threshold can be shifted. This threshold is calculated with a
hysteresis of 10% for a load exceedance value of 100 W as follows:
Switch-on point = 100 W; reset when the load falls below 90 W (switch-on value minus hysteresis).
The "Minimum time of exceedance" indicates how long an exceedance must be measured before
the action is triggered. For example, a minimum time of 10 s for a load exceedance value of 100 W
means that a value above 100 W must be measured for 10 s before the exceedance action is
triggered. The minimum time for exceedance works together with the hysteresis. So, if an
exceedance is measured, the power must fall below the set value minus hysteresis to stop the
dwell time.
The "Value on withdrawal of exceedance" triggers a defined action, which is carried out when a
load exceedance has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "value on withdrawal of exceedance"!

Monitoring of load undercut
The "Value for switching threshold" describes the value below which the selected action "Value
when undercut" is to be carried out.
The "Hysteresis" can be used to shift the switch-off threshold. This threshold is calculated with a
hysteresis of 10% for a load undercut value of 100 W as follows:
Switch-on point = 100 W; reset when 110 W is exceeded (switch-on value plus hysteresis).
The "Minimum time of undercutting" indicates how long an undercut must be measured before
the action is triggered. For example, a minimum time of 10 s for a load undercut value of 100 W
means that a value below 100 W must be measured for 10 s before the undercut action is triggered.
The minimum time for undercut works together with the hysteresis. So, if an undercut is measured,
the power must rise above the set value plus hysteresis to stop the dwell time.
The "Value on withdrawal of undercut" triggers a defined action, which is executed when a load
undercut has been exceeded again.
Important: After reset/reprogramming, the value for undercut must be undercut again in order to
send the "Value on withdrawal of undercut"!

Main meter / Intermediate meter
The main meter always works with the datapoint type 13.013 (kWh). For the intermediate meter,
the datapoint type can be set with the "Object selection" (Wh or kWh).
The setting "Send meter reading by change" can be used to set at which change the meter sends
its actual meter reading. If the setting is "not active", the meter does not send a value, no matter
how big the change is.

The setting "Send meter reading cyclically every ..." can be used to set the intervals at which the
device sends its actual measured value. The cyclical sending function can be activated or
deactivated independently of the setting "Send meter reading by change". Values are also sent if
the meter has not recorded a change. If both parameters are deactivated, no value is ever sent.
Yield meter
The settings for sending the yield correspond to the settings as for the main and intermediate meter.
Event A / Event B
Two different events can be triggered if certain conditions are met. This is done via 1-bit objects.
• final value: intermediate/main meter
Event is activated with a fixed value.
• final value: costs intermediate/main meter
Event is activated when a certain cost level is reached.
• time
Event is executed recurrently at a certain time. In addition to hours and minutes, it is also
possible to set whether the event is to be activated on certain days.
• interval
Event is activated recurrently at a defined interval (in hours and minutes).
Important: The starting point and subsequent cyclical transmission repetition is always after
reprogramming or when the bus voltage returns.
In addition to sending the object (Event A or Event B), other actions can be performed. These can
be activated individually as required.

The "Object selection" determines whether the values are to be output in "W" or "KW". With "Send
value by change" it can be set at which change (in %) the corresponding value is to be sent on the
bus. "Send cyclically" determines the constant intervals at which the current value is to be sent.
Monitoring of load exceedance
The "Value for load exceedance" describes the value above which the selected action “Value
when exceeded” is to be carried out.
With the “Hysteresis”, the switch-off threshold can be shifted. This threshold is calculated with a
hysteresis of 10% for a load exceedance value of 100 W as follows:
Switch-on point = 100 W; reset when the load falls below 90 W (switch-on value minus hysteresis).
The "Minimum time of exceedance" indicates how long an exceedance must be measured before
the action is triggered. For example, a minimum time of 10 s for a load exceedance value of 100 W
means that a value above 100 W must be measured for 10 s before the exceedance action is
triggered. The minimum time for exceedance works together with the hysteresis. So if an
exceedance is measured, the power must fall below the set value minus hysteresis to stop the
dwell time.
The "Value on withdrawal of exceedance" triggers a defined action, which is carried out when a
load exceedance has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "Value on withdrawal of exceedance"!

Monitoring of load undercut
The "Value for load undercut" describes the value below which the selected action "Value when
undercut" is to be carried out.
The "Hysteresis" can be used to shift the switch-off threshold. This threshold is calculated with a
hysteresis of 10% for a load undercut value of 100 W as follows:
Switch-on point = 100 W; reset when 110 W is exceeded (switch-on value plus hysteresis).
The "Minimum time of undercutting" indicates how long an undercut must be measured before
the action is triggered. For example, a minimum time of 10 s for a load undercut value of 100 W
means that a value below 100 W must be measured for 10 s before the undercut action is triggered.
The minimum time for undercut works together with the hysteresis. So if an undercut is measured,
the power must rise above the set value plus hysteresis to stop the dwell time.
The "Value on withdrawal of undercut" triggers a defined action, which is executed when a load
undercut has been exceeded again.
Important: After reset/reprogramming, the value for undercut must be undercut again in order to
send the "Value on withdrawal of undercut"!
Reactive power / Apparent power / Power factor cos Phi
In addition to the active power, the calculated values of the reactive power, the apparent power
and the power factor cos Phi can also be output. For the reactive and apparent power, the "Object
selection" can be used to determine whether the values are to be output in "W" or "KW". With
"Send value by change" it can be set at which change (in %) the corresponding value is to be sent
on the bus. "Send cyclically" defines the constant intervals at which an actual value is to be sent.

Current measurement
The "Object selection" determines whether the values are to be output in "A" or "mA". With "Send
value by change" it can be set at which change (in %) the corresponding value is to be sent on the
bus. "Send cyclically" determines the constant intervals at which the current value is to be sent.
Monitoring of current exceedance
The "Value for current exceedance" describes the value above which the selected action “Value
when exceeded” is to be carried out.
With the “Hysteresis”, the switch-off threshold can be shifted. This threshold is calculated with a
hysteresis of 10% for a load exceedance value of 100 mA as follows:
Switch-on point = 100 mA; reset when the load falls below 90 mA (switch-on value minus
hysteresis).
The "Minimum time of exceedance" indicates how long an exceedance must be measured before
the action is triggered. For example, a minimum time of 10 s for a current exceedance value of 100
mA means that a value above 100 mA must be measured for 10 s before the exceedance action is
triggered. The minimum time for exceedance works together with the hysteresis. So if an
exceedance is measured, the current must fall below the set value minus hysteresis to stop the
dwell time.
The "Value on withdrawal of exceedance" triggers a defined action, which is carried out when a
current exceedance has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "Value on withdrawal of exceedance"!
Monitoring of current undercut
The "Value for current undercut" describes the value below which the selected action "Value
when undercut" is to be carried out.
The "Hysteresis" can be used to shift the switch-off threshold. This threshold is calculated with a
hysteresis of 10% for a current undercut value of 100 mA as follows:
Switch-on point = 100 mA; reset when 110 mA is exceeded (switch-on value plus hysteresis).
The "Minimum time of undercutting" indicates how long undercutting must be measured before
the action is triggered. For example, a minimum time of 10 s for a current undercut value of 100 mA
means that a value below 100 mA must be measured for 10 s before the undercut action is
triggered. The minimum time for undercut works together with the hysteresis. So if an undercut is
measured, the current must rise above the set value plus hysteresis to stop the dwell time.
The "Value on withdrawal of undercutting" triggers a defined action, which is carried out when a
current undercut has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "Value on withdrawal of exceedance"!

Voltage measurement
Use "Send value by change" to set the change (in %) at which the corresponding value is to be sent
to the bus. "Send cyclically every" defines the constant intervals at which the current value is to be
sent.
Monitoring of voltage exceedance
The "Value for voltage exceedance" describes the value above which the selected action “Value
when exceeded” is to be carried out.
With the “Hysteresis”, the switch-off threshold can be shifted. This threshold is calculated with a
hysteresis of 10% for a load exceedance value of 200 V as follows:
Switch-on point = 200 V; reset when the load falls below 180 V (switch-on value minus hysteresis).
The "Minimum time of exceedance" indicates how long an exceedance must be measured before
the action is triggered. For example, a minimum time of 10 s for a voltage exceedance value of 200
V means that a value above 200 V must be measured for 10 s before the exceedance action is
triggered. The minimum time for exceedance works together with the hysteresis. So if an
exceedance is measured, the power must fall below the set value minus hysteresis to stop the
dwell time.
The "Value on withdrawal of exceedance" triggers a defined action, which is carried out when a
voltage exceedance has fallen below again.
Important: After reset/reprogramming, the value for the switching threshold must be exceeded
again in order to send the "Value on withdrawal of exceedance"!
Monitoring of voltage undercut
The "Value for voltage undercut" describes the value below which the selected action "Value
when undercut" is to be carried out.
The "Hysteresis" can be used to shift the switch-off threshold. This threshold is calculated with a
hysteresis of 10% for a voltage undercut value of 200 V as follows:
Switch-on point = 200 V; reset when 220 V is exceeded (switch-on value plus hysteresis).
The "Minimum time of undercutting" indicates how long undercutting must be measured before
the action is triggered. For example, a minimum time of 10 s for a voltage undercut value of 200 V
means that a value below 200 V must be measured for 10 s before the undercut action is triggered.
The minimum time for undercut works together with the hysteresis. So if an undercut is measured,
the voltage must rise above the set value plus hysteresis to stop the dwell time.
The "Value on withdrawal of undercut" triggers a defined action, which is executed when a
voltage undercut has been exceeded again.
Important: After reset/reprogramming, the value for undercut must be undercut again in order to
send the "Value on withdrawal of undercut"!

The setting "Send meter reading cyclically every ..." can be used to set the intervals at which the
meter sends its actual measured value. The cyclical sending function can be activated or
deactivated independently of the setting "Send meter reading by change". Values are also sent if
the meter has not recorded a change. If both parameters are deactivated, no value is ever sent.
Cost meter
The settings for sending the cost reading correspond to the settings as for the main and
intermediate meter.
Event A / Event B
Two different events can be triggered if certain conditions are met. This is done via 1-bit objects.
• final value: intermediate/main meter
Event is activated with a fixed value.
• final value: costs intermediate/main meter
Event is activated when a certain cost level is reached.
• time
Event is executed recurrently at a certain time. In addition to hours and minutes, it is also
possible to set whether the event is to be activated on certain days.
• interval
Event is activated recurrently at a defined interval (in hours and minutes).
Important: The starting point and subsequent cyclical transmission repetition is always after
reprogramming or when the bus voltage returns.
In addition to sending the object (Event A or Event B), other actions can be performed. These can
be activated individually as required.

Main meter / Intermediate meter
The main meter always works with the datapoint type 13.013 (kWh). For the intermediate meter,
the datapoint type can be set with the "Object selection" (Wh or kWh).
The setting "Send meter reading by change" can be used to set at which change the meter sends
its actual meter reading. If the setting is "not active", the meter does not send a value, no matter
how big the change is.

The setting "Send meter reading cyclically every ..." can be used to set the intervals at which the
meter sends its actual measured value. The cyclical sending function can be activated or
deactivated independently of the setting "Send meter reading by change". Values are also sent if
the meter has not recorded a change. If both parameters are deactivated, no value is ever sent.
Yield meter
The settings for sending the yield are the same as for the main and intermediate meters.
Event A / Event B
Two different events can be triggered if certain conditions are met. This is done via 1-bit objects.
• final value: intermediate/main meter
Event is activated with a fixed value.
• final value: costs intermediate/main meter
Event is activated when a certain cost level is reached.
• time
Event is executed recurrently at a certain time. In addition to hours and minutes, it is also
possible to set whether the event is to be activated on certain days.
• interval
Event is activated recurrently at a defined interval (in hours and minutes).
Important: The starting point and subsequent cyclical transmission repetition is always after
reprogramming or when the bus voltage returns.
In addition to sending the object (Event A or Event B), other actions can be performed. These can
be activated individually as required (see table above).
