7.3 Description of the connections
Connection
Description
A1, A1‘ and A2
Supply voltage DC/AC 24
… 240 V 0/50/60 Hz
Y0
Supply voltage for digital inputs, approx. 18V DC
Y1, Y2, Y3, Y4
Digital inputs, K1...3 external on or off, control the Analog outputs
RJ45
Ethernet and Modbus TCP interface
Out 20 mA: GND and I+
Analogue output 0/4…20 mA for adjustable loads (control output) or as
transducer (measurement converter)
Out 10 V: GND U+
Analogue output 0/2…10 V for adjustable loads (control output) or as
transducer (measurement converter)
12,11,14; 22,21,24; 32,31,34
Relays K1, K2 and K3 (max. 9A direct)
L1, L2, L3 and N
Voltage measurement, phase L1, L2, L3 and neutral conductor
1l1(k), 1l2(l); 2l1(k), 2l2(l);
3l1(k), 3l2(l)
Current measurement, phase L1, L2 and L3 (only through current
transformers),
k = secondary power plant, l = secondary load
7.4 Functional characteristics
Sign of the measured active
power
+
: Draw (imported from the grid = purchase)
-
: Feed-in (excess) (exported to the grid)
Priorities / Priority
Highest: Timer function (Web only)
Medium: Digital input (Y4 highest, Y lowest)
Lowest: Normal switching function
Consideration of connected
loads/consumers
Depending on the selected program, connected loads / consumers are
taken into account to identify internal connect / disconnect limits
Influence of delay times
Depending on the program, determines not only the limit of the
connection sequence but also the set delay times
(
larger load
should have
shorter time
and therefore has
priority
)
Implement minimum run times
(
Min on
)
Minimum run times of, e.g. heat pumps, washing machines, etc. can be
implemented through the minimum start-up time (
Times -> Min on Kx
);
once a load/consumer is switched on, shut-down is earliest after the set
time
Implement minimum switch-off
time
(
delay on
)
Minimum off time of, for example, heat pumps, etc. can be implemented
through the delay ON time (
Times -> delay on
), this time runs out before
the On consumer is switched on, the minimum switch off time of the
consumer can be set, the delay ON time can also be set shorter
SG ready
In Program 4, the EFR4001IP also supports
SG ready devices / heat pumps:

command
Min / Max values
All the min and max values are stored zero voltage retentive; press the
2s button
to delete the currently displayed min and max values
zero export / import device,
relay function
In PR5, 6, 7 and 8 the relay position cannot be adjusted; the closed-
circuit current principle always applies here i.e. the limit value is not
exceeded/undercut = relay actuated (x1-x4)
zero export / import device,
monitor function
In PR5,6, 7 and 8 the set limit values determine the monitoring function
of the associated relay: (observe Info -> warnings)
Power Kx off
>
Power Kx on
= MAX monitoring (exceed)
Power Kx off
<
Power Kx on
= MIN monitoring (undercut)
