6 Description and function
6.1 Product description
6.1.1 Function description
The switchgear is used to control a single electric pump in “sprinkler systems” in accordance with APSAD (T1-2).
In automatic mode the pump is switched on according to the unit pressure. Each pump has 2 pressure switches
at its pressure connection to monitor the pressure. Each pressure switch is controlled by a key switch.
When the pump is started, it can only be switched off manually and only when the pressure has been reached in
the unit.
In manual mode the start of the pump is activated from the HMI.
The st art-up of the pump is done by means of a start-up tank, the filling of which is controlled by a float switch.
States of system operation such as availability, pump operation, malfunctions, etc. are visually indicated by
LEDs on the front of the switchbox and equally by a buzzer. Operating parameters such as current or voltage
values are displayed on the screen. The operation is performed by means of the rotary knob, key switches and
buttons accessible on the front of the switchbox.
Potential-free contacts are available for transmitting the collective run or malfunction signals to a possible
BMS (building management system).

6.1.2 Structure of the switchgear (Fig. 1) The installation of components in the switchbox depends on the performance of the pump connected.
The switchgear includes the following main components:
• Main on/off switch: Power supply of the switchgear (pos. 7)
• Human-machine interface (HMI): signal lamps or screen for displaying the state of operation (for example
availability, malfunction and rated current of the pump), user test of the pump and function allowing error
messages to be acknowledged (pos. 1, 2, 3)
• Key switch: selection of operating mode (manual, deactivation, automatic) of the pressure switches
(pos. 4, 5)
• Change-over switch (pos. 14): access to level 2
• Buzzer signal: additional buzzer for certain error messages (pos. 6)
• “SC controller” PCB: printed circuit board with microcontroller (pos. 9)
Warni ng: There are 2 “SC controller” PCBs, fixed with spacer sleeves to superimpose them.
• “SC U/I” PCB: Measurement/acquisition voltage/current (pos. 10)
• Current converter: pump current measurement (pos. 11)
• Fuse protection: protection of the pump motor (pos. 12)
• Contactor: Contactor of the motor of the pump (pos. 13)
• “SC Display” PCB: printed circuit board with display and rotary button (pos. 14)
• “SC I/O” PCB: printed circuit board with control/operating console (pos. 15)
• Key box: enables the storage of the keys from the key switches (pos. 8)
6.2 Function and operation
DANGER! Risk of death!
When working on an open switchgear, there is a risk of electrocution in the event of
contact with active conductors.
This work must only be carried out by qualified personnel!
After connecting the switchgear to the connection voltage as well as after each network cut-off, the
switchgear reverts to the operating mode set before the voltage cut-off.
6.2.1 Switchgear operating modes of the start/deactivation After connection to the power supply, the switchgear can be switched on or off using the main switch.
Once the main switch has been activated, the system is instantly ready for operation. After several seconds,
the green signal lamp (Fig. 2, pos. 1) lights up.

Operating mode You can define the operating mode of the switchgear by selecting one of the three positions of the key
switch “Auto”, “0” or “Manual”.
Starting the
motor with...
Table 3: Operating modes
Automatic mode
The key switch (Fig. 1, pos. 4, 5) is placed in the “Auto” position, the “Auto” position is thus confirmed by the
corresponding green LEDs (Fig. 2, pos. 15, 16) .
The unit starts up automatically once the pressure switch no. 1 opens and the key switch no. 1 is in the “Auto”
position or once the pressure switch no. 2 activates and the key switch no. 2 is in the “Auto” position.
Any open pressure switch is signalled by a green LED for pressure switch 1 or a yellow LED for the pressure
switch 2 (Fig. 2, pos. 19, 20). Triggering of the float switch (low level of start-up tank) st arts the pump if at least
one of the 2 key switches is in the “Auto” position.
Non-automatic mode
This mode is activated when the key switches are not in the “Auto” position.
This operating mode is signalled by the red LEDs (Fig. 2, pos. 17, 18).
Furthermore, the output “NON-AUTO MODE 1/2” is activated.
Manual mode To perform a manual start-up, place one of the key switches in the “Man” position. The manual start button “ON”
(Fig. 2, pos. 8) enables start-up of th e pump. Deactivation mode
To switch off the pump, at least one of the key switches must be in the “0” position.
As soon as the pressure switch or the float switch is no longer activated, the pump can be switched off by
means of the “OFF” button (Fig. 2, pos. 12).

Pump start-up In auto mode, if the pressure measured by at least one of the two pressure switches is below the switch-on
threshold, the LED/LEDs (“active” Fig. 2, pos. 19 and pos. 20) turn/s on green for pressure switch 1 or yellow
for pressure switch 2. Once the follow-up time has elapsed (see menu 1.2.5.1) the pump starts.
Note: If the follow-up time (menu 1.2.5.1) is quite long, it is possible to see the LED flashing while the follow-up
time elapses.
The LED (“on” Fig. 2, pos. 13) turns on green and signals the operation of the pump. Throughout pump
operation, the instantaneous current of the pump is monitored and displayed on the screen. When a malfunction
arises, and even if the pump continues to function, the error code of the malfunction is displayed for
30 seconds.

English
Once the set pressure is reached or exceeded it is possible to switch off the LED/LEDs (“active” Fig. 2,
pos. 19 and pos. 20) previously turned on by pressing the malfunction acknowledgement. The pump is
still running and must be switched off manually.
Start-up tank
If the level of water in the start-up tank of the pump is less than 2/3 of the full level, the float switch closes and the
red indicator light is activated (Fig. 2, pos. 6). Following a configurable follow-up time (see menu 1.2.5.2) the
pump switches on and the green indicator light (Fig. 2, pos. 13) is activated.
Note: As the follow-up time expires, the indicator light flashes
As soon as the tank is full, the float switch opens and the error message can be acknowledged. The indicator light
turns off (Fig. 2, pos. 6) and the pump can be switched off manually. The audible warning (Fig. 2, pos. 13)
deactivates also.
Control of the voltage
To increase operational safety, the power supply voltage of the switchbox is subject to permanent control.
The power supply voltage is configured in the menu 1.2.1.1 (400 V by default), the 3 phases are controlled.
When the pump is on standby, the 3 phase-to-phase voltages are displayed one after another.
As soon as the power supply voltage is lower or higher than the defined tolerance level (see menus 5.4.1.0
and 5.4.2.0), an error code is displayed after a certain time lag (see menu 1.2.5.3).
When the pump is in operation, and in case of a malfunction, the pump continues to function.
Protection against excess currents
During pump functioning, the current is subject to permanent monitoring.
The rated current motor is configurable in the menu 1.2.1.2.
The current is monitored over the three phases. When the pump is functioning, the current is indicated on the
screen. The green indicator light (“on” Fig. 2, pos. 13) turns on as soon as the current of the pump reaches a
predefined minimum level (see menu 5.4.3.0).
As soon as the current of the pump exceeds the maximum threshold (see menu 5.4.4.0), the red indicator light
(“malfunction” see menu 1.2.5.5) (Fig. 2, pos. 14) turns on.
Despite the presence of an error, this does not prevent the pump from starting or continuing to function. As soon
as the current level of the pump returns to within the range of the levels permitted, you can acknowledge the
error. And the indicator light (Fig. 2, pos. 14) deactivates.
Monitoring of the “pump in demand”
As soon as the pump switches on, a pressure switch located at the pressure connection monitors whether the
pressure at the pump outlet is correct.
After a certain predefined time (see menu 1.2.2.2), if the pressure at the pump outlet is not reached, the red
indicator light turns on (“pump in demand” Fig. 2, pos. 3).
When the pressure exceeds the configured threshold, the error message can be acknowledged and the indicator
light will change to green (Fig. 2, pos. 3).
Monitoring of failed start-up
When the pump is in operation, and after a certain predefined time in the menu 1.2.2.1, the electrical power
consumption is monitored.
The power is monitored against the following parameterisation: 1.2.1.1 and 1.2.1.2.
During the monitoring period, and after a certain configured lag time (see menu 1.2.5.6), if the minimum value has
not been reached (see menu 5.4.5.0), the indicator light will turn yellow (Fig. 2, pos. 2).
When the power consumed is reached again, the error message can be acknowledged. And the indicator light will
change from yellow to green (Fig. 2, pos. 2).

Description of cabinet components:
• Key switches (Fig. 1, pos. 4 and 5)
Pressure switch no. 1 and pressure switch no. 2 each have a key switch.
The 3 positions available are: Auto / Off / Manual.
The keys can only be withdrawn if the key switches are in the “Auto” position. Once the “0” or “Manual”
position has been selected, it is not possible to launch an automatic start-up of the pump, even if the
pressure switch or the float switch are active.
The status corresponding to the “Auto” position is signalled by the green LEDs (Fig. 2, pos. 15, 16) and
that which corresponds to the “0” or “Manual” position by the red LEDs (Fig. 2, pos. 17, 18).
• Key change-over switch (Fig. 1, pos. 14)
Enables access to the functions of level of access 2.
• “ON” (Fig. 2, pos. 8)
By pressing this button, the pump starts manually. To do this, at least one of the two key switches must be
in the “Manual” position. Pump operation is signalled by the green signal lamp (Fig. 2, pos. 13). The pump
must be switched off manually and the signal lamp (Fig. 2, pos. 13) turns off also.
• “BUZZER OFF” (Fig. 2, pos. 9)
This button (level 1) allows an audible signal emitted in case of alarm to be cleared separately. As
soon as a new malfunction arises, the buzzer signal sounds once again.
• “OFF” (Fig. 2, pos. 12)
By pressing this button, the pump switches off manually. To do this, at least one of the two key switches
must be in the “0” position and neither the pressure switch nor the float switch must be activated. The
pump can only be switched off with this button.
• “LAMP TEST” (Fig. 2, pos. 10)
By pressing this button (level 1), all the signal lamps (Fig. 2, pos. 1 to 20) and the buzzer activate and remain
activated while the button is pressed down. This allows for the control of correct operation of all of the LEDs.
Once the button is released, the signal lamps and the alarm buzzer turn off or remain turned on if the
functioning demands it.
• “RESET” (Fig. 2, pos. 11)
By pressing this button (level 2 required), all the error messages/signal lamps are reset insofar as the
cause of the error has been eliminated.
6.2.3 Display elements of the switchgear
“LIVE”
The signal lamp (Fig. 2, pos. 1) turns on green if the power supply is established and if it has been activated
with the main on/off switch.
“ON” The signal lamp (Fig. 2, pos. 13) turns on green if the pump is running and the current consumed by the
pump motor falls within the tolerance limits set (see menu 5.4.3.0).
Installation and operating instructions Wilo-SC-Fire Electric A2P 39
English
“START-UP FAILURE” When the pump is running, the power consumed by the pump is permanently monitored. At pump start-up and after a set follow-up time (see menu 1.2.2.1), if the power consumed by the pump is
below the threshold set (see menu 5.4.5.0), the LED (Fig. 2, pos. 2) turns on.
“PUMP IN DEMAND” As soon as the pump is operating and the matching pressure switch does not close after a defined period (see
menu 1.2.2.2), the signal lamp (Fig. 2, pos. 3) lights up red.
“SYSTEM MALFUNCTION” The yellow signal lamp (Fig. 2, pos. 4) signals a software malfunction if the communication between the
control board and the display board is disrupted and the software routine can no longer take place.
“TANK EMPTY” If the water tank level is too low, the LED (Fig. 2, pos. 5) turns on red.
“START-UP TANK LEVEL MALFUNCTION” The signal lamp (Fig. 2, pos. 6) turns on red as soon as the level of the pump start-up tank falls below 2/3 and
when the float switch is triggered. If at least one key switch is in the “Auto” position, the pump starts
automatically. If the level rises sufficiently, the signal lamp (Fig. 2, pos. 6) turns off again. The pump must be
switched off manually.
“LEVEL MINI GLYCOL TANK” If the glycol tank level is too low, the LED (Fig. 2, pos. 7) turns on red. If the malfunction occurs when the pump is in operation the pump continues to function. You can acknowledge the error message and the indicator light (Fig. 2, pos. 7) when the level of the glycol tank
is once again above the low level.
“MALFUNCTION” A signal lamp (Fig. 2, pos. 14) turns on red:
- upon activation of the pump protection device,
- if the thermistor of the motor is triggered,
- if the fuse switch amplifier is open,
- if the fuses have been triggered,
- if a phase sequence malfunction occurs,
- or if a malfunction is detected at the control voltage.
“AUTO MODE” The signal lamp (Fig. 2, pos. 15/16) is turned on green if the matching key switch is in the “Auto” position. In the
automatic mode, the automatic start-up of the pump is possible either via the intermediary of the float switch or
the corresponding pressure switch.
“NON-AUTO MODE” The signal lamp (Fig. 2, pos. 17/18) is turned on red if the matching key switch is in the “0” or “Manual”
position. In the non-automatic mode, no automatic start-up of the pump is possible via the intermediary of the
float switch or the corresponding pressure switch.
WILO SE 01/2017 40
English
“ACTIVE” When the pressure in the unit falls below the threshold set on the pressure switches, the pressure switch(es)
becomes active. The LED flashes green (for pressure switch 1) or yellow (for pressure switch 2).
After the elapsed follow-up time (menu 1.2.5.1), the LED remains turned on permanently.
If key switch 1 or 2 is in the “Auto” position, the pump starts automatically.
When the pressure rises and exceeds the threshold set, the pressure switch passes to the passive state. It is
possible to turn off the LED by pressing the acknowledgement button (Fig. 2, pos. 11).
The acknowledgement is only accessible if the user has previously connected to level 2.
