ENGLISH
Thermostat. The pump’s thermal con-
tact has been triggered. The pump is
then switched off. This error must be
acknowledged on the control unit. If
the error condition no longer exists,
the control unit starts up again. This
error condition will also be saved in the
event of a power failure. The message is
saved in the EEPROM of the processor,
which is zero voltage safe.
Running time. The maximum running
time of the pump has been exceeded.
Sensor error. An error has occurred in
the level measurement system. (Short
circuit or interruption in the power
supply lines to the level sensor; meas-
ured value lies outside the range 4 - 20
mA) The pumps is switched off. If the
high-water float switch is activated in
this situation, however, the pump will
be switched on, provided that the pump
is not faulty.
Sensor logic. An error has occurred in
the level measurement system. (Incon-
sistent switching status of float switch -
es). The pump is then switched off. If the
high-water float switch is activated in
this situation, however, the pump will be
switched on, provided that the pump is
not faulty. This error condition will also
be saved in the event of a power failure.
The message is saved in the EEPROM
of the processor, which is zero voltage
safe.
Dry running. The water level is too low
to start the pump up safely according to
ATEX.
ASSEMBLY
Only electricians may carry out
electrical work! Before com-
mencing work, always ensure
that the unit is at zero voltage by un-
screwing the pre-fuses!
When using the control, the respec-
tive national laws and regulations as
well as local regulations on protection
against explosion must be observed,
such as European standards EN 60079-
0:2012:A11:2013, EN 60079-1:2014 and
EN 1127-1:2011.
Do not install the control unit itself in
explosion hazard areas or in the collect-
ing chamber!
The control unit must be installed only
in well-ventilated areas - high humidity
can destroy the control unit!
Install the unit above the local backup
level and in a position that allows easy
access for inspections at all times.
Please read and follow the safety in-
structions in the first section. Loosen
the screws and open the housing door
to connect the control unit. The display
is sensitive to mechanical damage.
Dashed connections on the diagram
must be made by the user.
Mains: To provide a separate pre-fuse,
use safety fuses:
- HIGHLOGO 2-610 - 25 A,
- HIGHLOGO 2-910 - 25 A,
- HIGHLOGO 1-910 - 20 A,
- HighLogo 2-00E - 20 A,
- HIGHLOGO 2-46 - 20 A,
- All others - 16 A.
The mains power cable (5 G1.5 mm² to
max. 5 G4 mm²) must be connected to
terminals L1, L2, L3, N, and the PE ter-
minal block.
Connecting the pumps
The pump cable wires marked U1, V1
and W1 must be connected up, and PE
must be attached to the PE terminal
block. The pump cable wires marked
30/32 (motor thermal contacts) must be
attached to terminals 30/32 for pump 1
and pump 2 separately.
Motor protection switch
The control unit is fitted with a motor
protection relay. The rated current at
the motor protection relay must be set
to correspond to the motor data. The
control unit records the triggering event
and saves it in a zero voltage safe mem-
ory. In ATEX operation, this means that –
irrespective of an automatic reset – the
pump cannot be operated again until
the error has been acknowledged on
the control unit.
The control must be opened to enable
a motor protection RESET to be carried
out.
If the rotating direction is correct, the
start-up jolt of the pump is in the op-
posite direction to that shown by the
rotational direction arrow located on
the motor housing. If the direction of
rotation is not correct, the two phases
of the pump cable must be reversed on
the control unit.
Before starting up for the first
time, check that the protective
measures function properly!
Alarm contacts
Connect the non-isolated alarm relay to
terminals N/X2 (normally open contact)
or N/X3 (normally closed contact).
Connect remote fault indication
The potential-free change-over con-
tact (40-41-42) can be loaded with max.
5A/250V AC. The relay operates accord-
ing to the quiescent current principle,
i.e. the relay drops out in the event of a
fault or voltage drop.
The change-over contact (50-51-52)
for separate high water alarm can be
loaded with max. 5A/250V AC. The re-
lay operates according to the operating
current principle, i.e. the relay picks up
in the event of a fault.
Level detection
If the control unit is operated with a level
sensor, the sensor must be connected
to terminals 9(+) and 10(-). ATTENTION!
Check that the poles are connected the
right way round!
If the control unit is not operated with a
level sensor but with switches, the switch
for the base load must be connected to
terminals 21(-) and 23(+). Because this
is a simple normally open contact, the
poles are unimportant here.
When operating with two pressure
switches, the second pressure switch is
to be connected to terminals 27/28. It is
used to detect high water and the peak
load function.
When operating with three submersible
ball contact switches, the high water
function and peak load functions are
separate:
- Base load ON-OFF Terminal 21/23
- Peak load ON-OFF Terminal 24/25
- High water alarm Terminal 27/28
If a separate OFF float switch is connec -
ted
- Pump(s) OFF Terminal 21/22
- Base load ON Terminal 22/23
- Peak load ON Terminal 24/25
- High water alarm Terminal 27/28
In explosion protected areas, however,
submersible ball contact switches must
be connected via an explosion protected
auxiliary switching module.
Level measurement with the static
air pressure system
If the static air pressure system is
used for measuring the water levels
(using switches or pressure sensors),
two measurement systems are usually
