6.2 Function and operation
DANGER! Risk of fatal injury!
When working on the open switchgear, there’s a
danger of electric shock from touching the live
components.
This work must only be carried out by qualified
personnel!
NOTE:
After connecting the switchgear to the supply
voltage, as well as after every mains interruption,
the switchgear returns to the operating mode set
before the power interruption.
6.2.1 Switchgear operating modes (Fig. 2)
Switching the switchgear on/off
After connection to the mains supply, the switchgear can be switched on or off using the main
switch. Once the main switch has been switched
on, the system is ready for operation after a few
seconds (the start phase). If the supply voltage is
within the set parameters, standby is indicated by
the signal lamp (Fig. 2, item 1) lighting up green.
Pump request
If the pressure drops below the set target pressure
at leas
t one of the two pressure switches, the signal lamp lights up (Fig. 2, item 4). After a configurable delay period (see menu 1.2.5.1) (LED flashes),
the connected pump is activated. The signal lamp
(Fig. 2, item 2) lights up green, indicating that the
pump is in operation.
Once the pressure reaches or exceeds the target
pressure, the signal lamp (Fig. 2, item 4) goes out
again but the pump remains activated. The pump
has to be switched off manually. The signal lamp
(Fig. 2, item 2) then goes out.
Priming device
If the level of the pump priming tank falls below
2/3, the float switch closes and the signal lamp
(Fig. 2, item 5) lights up white. After a configurable delay time (see menu 1.2.5.2) (LED flashes),
the pump activates and the signal lamp (Fig. 2,
item 2) lights
up green. Once the pump priming
tank is full and the float switch opens again, the
signal lamp goes out (Fig. 2, item 5) and the pump
eithe
r switches off again automatically or it has to
be deactivated manually (see menu 5.2.2.0).
The signal lamp (Fig. 2, item 2) then goes out.
Voltage monitoring
To improve operational reliability, the mains
power supply is monitored continuously. To do
this, the correct supply voltage has to be set in
menu 1.2.1.1. The voltage is monitored individually between all three live wires. If no pump is running (standby), the voltage in the display switches
alternately between all three conductors. When
the supply voltage exceeds or drops below the
configurable tolerances (see menu 5.4.1.0 and
5.4.2.0), the signal lamp (Fig. 2, item 1) goes out
after a configurable delay (see menu 1.2.5.3) and
the collective fault signal (Fig. 2, item 6) lights up
yellow. If a fault occurs, the pump nevertheless
starts or continues running. Once the voltage is
back within the tolerance range, the fault is selfacknowledging. The signal lamp (Fig. 2, item 6)
oes out and the signal lamp (Fig. 2, item 1) lights
g
up green again.
Current monitoring
The pump current is monitored while the pump is
in operation. To do this, the correct rated current
for the pump has to be set in menu 1.2.1.2. The
current is monitored individually in all three conductors. If the pump is running, the pump current
in the display switches alternately between all
three conductors. The signal lamp (Fig. 2, item 2)
lights up green once the pump current reaches a
configurable minimum threshold (see menu
5.4.3.0). When the pump current exceeds or drops
below the configurable tolerances (see menu
5.4.3.0 and 5.4.4.0), the signal lamp (Fig. 2, item 6)
ghts up after a configurable delay (see menu
li
1.2.5.5). If a fault occurs, the pump nevertheless
starts or continues running. Once the pump current is back within the tolerance range, the fault
can be
acknowledged. The signal lamp (Fig. 2,
item 6) goes out.
Monitoring hydraulic false start
Once the pump has started, the hydraulic output is
monitored by a pressure switch on the pump. If
the pump does not build up any pressure after the
configurable period of time (see menu 1.2.2.2) and
the pressure switch on the pump remains open,
the signal lamps (Fig. 2, item 6) and (Fig. 2, item 3)
light up. If the pump is running, the relevant pressure has been reached and the pump pressure
switch is closed accordingly, the fault can be
acknowledged. The signal lamps (Fig. 2, item 6)
and (Fig. 2, item 3) go out and the signal lamp
(Fig. 2, item 2) lights up green.
Monitoring electric false start
Once the pump has started
, the pump’s electric
output is monitored for a configurable period of
time after the start (see menu 1.2.2.1). To do this,
the correct pump output has to be set in menu
1.2.1.3. If the configurable minimum threshold (see
menu 5.4.5.0) is not reached within the monitoring
period, the signal lamps (Fig. 2, item 6) and (Fig. 2,
item
3) light up after a configurable delay period
(see menu 1.2.5.4) plus the time for the star/delta
changeover (see menu 1.2.5.6). If the pump is running and the relevant pump output has been
reached, the fault can be acknowledged. The signal
lamps (Fig. 2, item 6) and (Fig. 2, item 3) go out and
the signal lamp (Fig. 2, item 2) lights up green.
Logic reversal of the collective fault signal (SSM)
The required logic of the SSM can be set in menu
5.5.2.0. In this case, it is possible to select
between negative logic (falling edge in case of a
fault = “fall”) or positive logic (rising edge in case
of a fault = “raise”).

electrician approved by the local electricity supplier only and in accordance with local regulations.
• Observe the installation and operating instructions for the pumps and accessories!
• Disconnect the power supply before any work.
Warning! Danger of electric shock!
There is a potentially fatal voltage on the supply
side, even when the main switch is turned off.
• The type of mains, current and voltage of the
mains connection must match the details on the
rating plate of the control device.
NOTE:
• Fuse on mains side in acco
mation in the wiring diagram
• Feed the ends of the mains cable through the
threaded cable connections and cable inlets and
wire them according to the markings on the terminal strips.
• Earth the pump/installation in accordance with
the regulations.
NOTE:
In accordance with EN /IEC 61000-3-11 (see table
below), the switchgear and pump with motor
power of ... kW (column 1) are provided for operation on a mains power supply with a system imped-
ance of Zmax at the building connection of max. ...
Ohm (column 2) for a maximum number of ... connections (column 3).
If the mains impedance and the number of connections per hour are greater than the values
given in the table, the switchgear with the pump
may lead to temporary voltage drops and also to
disturbing voltage fluctuations (flickering) due to
the unfavourable mains conditions.
Therefore, measures may be necessary before the
switchgear
at this connection. The necessary information
must be obtained from the local electricity supply
company and the manufacturer.

Warning! Danger of electric shock!
There is a potentially fatal voltage on these terminals, even when the main switch is turned off.
8 Commissioning
WARNING! Risk of fatal injury!
Commissioning by qualified personnel only!
Improper commissioning poses a risk of fatal
i
njury. Have commissioning performed by quali-
fied personnel only.
DANGER! Risk of fatal injury!
When working on the open switchgear, there’s a
danger of electric shock from touching the live
components.
This work must only be carried out by qualified
personnel!
We recommend that you have the switchgear
commissioned by Wilo customer service.
Before switching on for the first time, the on-site
wiring must be checked, in particular the earthing.
Tighten all terminals prior to commissioning!
8.1 Switchgear settings
After switching on the main switch and expiration
of the start sequence in the display and of the signal lamps, the switchgear is ready for operat
and factory preset.
The factory settings can be rest
tomer service.
To ensure correct operation it is necessary to
implement and/or check certain settings in the
menu
Menu 1.2.1.1:
Setting of the supply voltage in volts.
Menu 1.2.1.2:
Setting of the pump’s rated current. Information
relating to the pump’s rated current is to be
inferred from the pump’s rating plate.
ored by Wilo cus-
ion
Menu 1.2.1.3:
Display of the pump’s capacity. The value used for
the capacity results from the set values for voltage
and current under menu 1.2.1.1. and menu 1.2.1.2.
Menu 5.2.1.0:
Setting of the transformer type (primary current
measuring range). Information relating to the
transformer type can be found on the transformer’s rating plate.
NOTE:
If the measuring line has not only been run
through the transformer but also wrapped around
it, the current value of the transformer is to be
halved for each wrapping.
Example:
The measuring line has been wrapped twice
around a 100/5A transformer.
1 wrapping = 50/5A transformer
2 wrappings = 25/5A transformer
A 25/5A transformer should th
menu.
Menu 3.1.0.0:
Setting of the operating mode to “Automatic on”
(automatic pump operation).
CAUTION! Risk of malfunctions!
If “Automatic off” is set, automatic mode is not
possible. The pump can only be switched on manually.
8.2 Checking the motor direction of rotation
By briefly switching on the pump, check that the
direction of rotation of the pump is correct. When
the pump motor runs out, compare the direction
of rotation of the fan wheel and the direction
specified on the pump housing.
If the direction of rotation of the pump is wrong,
swap over any two phases of the power cable.
