6.1 Description of the product (Fig. 1)

6.1.1 Function description

The switchgear is used to control an individual electric pump in sprinkler systems, in accordance with EN 12845. The pump can be switched on by the control depending on the pressure. Once the pump has started, it can only be stopped manually if the pressure in the system has not been reached. The pump can be controlled via a connected float switch in order to automatically replenish the pump priming tank. The pump can be switched on and off by the control depending on the pressure. The system’s operating statuses, such as standby, pump operation, fault etc., are displayed visually by LEDs on the door and operating parameters such as current or voltage values are shown on the display. The system is operated using the rotary knob and the buttons in the door.

6.1.2 Set-up of the switchgear (Fig. 1)

The set-up of the switchgear depends on the capacity of the pump to be connected. It consists of the following main components:

• Main switch: Switches the switchgear on/off

(Fig. 1, item 2)

• Human-machine interface (HMI): signal lamps or display for indicating the operating status (e.g. standby, fault, and rated pump current), rotary knob and buttons for menu selection, parameter input and operation (Fig. 1, item 1)

• Base board: printed circuit board with microcontroller (Fig. 1, item 6)

• Measurement board: converting current and voltage values (Fig. 1, item 7)

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 least 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 yellow. 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 can be deactivated manually. 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

Installation and operating instructions Wilo SC-Fire Electric

English starts or continues running. Once the voltage is back within the tolerance range, the fault is selfacknowledging. The signal lamp (Fig. 2, item 6) goes out and the signal lamp (Fig. 2, item 1) lights 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. If the pump is running, the pump current in the display switches alternately between all three conductors, and also the voltage between all three conductors is shown. 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) lights up after a configurable delay (see menu

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 voltage for the pump has to be set in menu 1.2.1.1, and the correct rated current in menu

1.2.1.2. 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”).

power of ... kW (column 1) are provided for operation on a mains power supply with a system impedance 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 with pump can be operated as intended at this connection. The necessary information must be obtained from the local electricity supply company and the manufacturer.

Installation and operating instructions Wilo SC-Fire Electric 49

English

7.2.1 Power supply connection

Connect the on-site 4-wire cable (L1, L2, L3, PE) for the supplying network to the main switch, in accordance with the wiring diagram.

7.2.2 Fault signal/run signals connection

A signal can be taken from the terminal strip for the fault signal/run signal via a potential-free contact in order to indicate a fault/operation

(see wiring diagram).

Potential-free contacts, max. contact load

250 V~/1 A

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 injury. Have commissioning performed by qualified 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 operation and factory preset.

The factory settings can be restored by Wilo customer 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.

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 therefore be set in the menu.

Menu 3.1.0.0:

Displaying the operating mode.

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.

9 Maintenance

Have maintenance and repair work carried out by qualified skilled personnel only!

DANGER! Risk of fatal injury!

There is a risk of fatal injury from electric shock when working on electrical equipment.

• The switchgear should be electrically isolated and secured against unauthorised switch-on during any maintenance or repair work.

• Any damage to the connection cable should only ever be eradicated by a qualified electrician.

• The switchbox must be kept clean.

• Visual inspection of the electric system parts in the switchbox

10 Faults, causes and remedies

DANGER! Risk of fatal injury!

There is a risk of fatal injury from electric shock when working on electrical equipment.

Have faults remedied by qualified skilled personnel only! Follow the safety instructions in

Section “2 Safety”.

Before all work to remedy faults, disconnect the unit from the power supply, and make sure it cannot be switched back on by unauthorised persons.

English

10.1 Fault indication

If a fault occurs, the relevant fault signal LED lights up, the collective fault signal and associated individual fault contact are activated and the fault is displayed on the LCD (fault code number).

The fault can be acknowledged by pressing the acknowledgement button (Fig. 2, item 10) or in menu 6.1.0.0 by proceeding as follows:

10.2 History memory for faults

A history memory has been set up for the switchgear and operates according to the FIFO principle

(first-IN, first-OUT).

The memory is configured for 16 faults. The fault memory can be called up using menus 6.1.0.1 –

6.1.1.6.
