6 Description and function

6.1 Product description

6.1.1 Function

The switchgear is used to operate a diesel motor pump in the sprinkler system in accordance with A2P (T1-1).

The manual start-up of the diesel motor is done from the HMI of the switchgear. Contrary to automatic start-up which is generated by a lack of pressure in one of the 2 pressure switches.

Each pump has 2 pressure switches and each pressure switch has an Auto/0/Manu key switch.

The automatic start-up of the diesel motor follows a start-up sequence which allows for the generation of 6 startup attempts, the 2 batteries are used in the course of this sequence.

The status of the unit can be seen on the front of the support box:

- From the LED panel

- From the LCD

- From the audible warning

The operation is performed by means of the rotary knobs, key switches and screen pushbuttons also located on the front of the box.

It is possible to perform an emergency start by means of the 2 buttons on the front of the cabinet. In this way, the battery voltage is directly applied to the terminals of the diesel starter, without going through the control.

The water level in the start-up tank is monitored at all times. If the level in the tank goes under 2/3 of the “full tank” level, then the diesel motor starts up to supplement the level.

Potential-free contacts are ready to transmit the collective run/malfunction signals to the BMS device.

6.1.2 Structure of the switchgear

The structure of the switchgear may vary according to the performance of the pump to be connected. The switchgear includes the following components:

• Main switch (Fig. 1, pos. 11): Power supply of the switchgear

• Human Machine Interface (HMI):

o LCD screen enabling operational data to be displayed (see menus) (Fig. 1, pos. 2), o LED indication of the status of the system (functioning/malfunctioning) (Fig. 1, pos. 1), o Control button enabling menu navigation, menu selection and entering of parameters

(Fig. 1, pos. 1, 2, 3).

• Key switch (Fig. 1, pos. 8 and 9): Operation mode (Auto/0/Manu) of pressure switches 1 and 2

6.2 Function and operation

English

DANGER! Risk of fatal injury! When working on an open switchgear, there is a risk of electrocution in the event of contact with the conductor components. Only authorised and qualified personnel may carry out the work!

Following connection of the switchgear to the connection voltage as well as after each network cutoff, the switchgear reverts to the operating mode set before the voltage cut-off.

6.2.1 Operating modes of the switchgear

Activation/deactivation of the switchgear

Once the batteries are connected to the switchgear and the voltage supply has been established, the control is operational after a few seconds. The green LED indicating the operational readiness (Fig. 2, pos. 1) is turned on.

By default, the remaining time before changeover to the other battery and charger is indicated on the LCD. The chargers and the heating which maintain the temperature of the motor oil constant can be switched on or

off via the main switch. To stop the operation, the terminals of connected batteries and the main switch must be disconnected.

Automatic mode

To operate the unit in automatic mode, put the key switches (Fig. 1, pos. 8, 9) in the “Auto” position, the “Auto” position is thus confirmed by the 2 green LEDs on the HMI (Fig. 2, pos. 30, 31).

The unit starts up automatically once the pressure switch no. 1 activates (drop in pressure, contact opening width) 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.

The status of the pressure switches is signalled by a green or yellow LED (Fig. 2, pos. 34, 35). In the event of a cable cut or connection malfunction of one of the 2 pressure switches, a red LED is activated

(Fig. 2, pos. 36, 37). This malfunction causes the diesel motor to start up automatically. In automatic mode, the diesel motor also starts up if the level of the start-up tank is less than 2/3 full. The motor

only stops through the intervention of a technician.

English

Automatic start-up process

The automatic start-up consists of a sequence of six consecutive start-up attempts. Each attempt lasts 15 seconds and is followed by a pause of 10 to 15 seconds. After each start-up attempt, the other battery is used for the following attempt. Even if there is no additional need on the float or key switch level, start-up attempts continue. The number of attempts with each battery will be constantly indicated on the LCD.

All successful start-ups are signalled by a green LED (Fig. 2, pos. 3) and the output “running” is activated. After six unsuccessful start-up attempts, an alarm signal is emitted, the output “failure to start” is activated and

the red “failure to start” LED is turned on (Fig. 2, pos. 5) as well as the yellow LED which signifies “attempt at manual start-up” (Fig. 2, pos. 22) (see test of start-up device 6.2.1).

After a successful start-up sequence or after a phase of “failure to start”, the yellow LED named “Operat e the test button for manual start-up if the indicator light is turned on” is turned on. (see device start-up test 6. 2.1).

Non-automatic mode

The key switch is not in the “Auto” position. Consequently, the corresponding pressure switch cannot activate automatic start-up.

If neither of the two key switches is in the “Auto” position, then the start-up tank also cannot activate automatic start-up. This operating mode is signalled by the red LEDs (Fig. 2, pos. 32, 33). Furthermore, the output “NON-AUTO MODE 1/2” is active.

Manual mode

To perform a manual start-up, place one of the key switches in the “Man” position. The manual start-up (like the automatic start-up) consists of a sequence of six consecutive start-up attempts. Each attempt lasts 15 seconds and is followed by a pause of 10 to 15 seconds. After each start-up attempt, the other battery is used for the following attempt.

Even when the key switch is not in the “Man” position, the start-up attempts continue.

Deactivation mode

To switch off the diesel motor, 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 diesel motor can be switched off by means of the “OFF” button (Fig. 2, pos. 21).

Emergency start

Start by lifting the emergency start button protection cap (Fig. 1, pos. 12 et 13). Subsequently, to start the diesel motor with battery no. 1, press the button “battery 1 emergency start”, and

keep the button pressed until start-up.

To start the diesel motor with battery no. 2, press the button “battery 2 emergency start”. In this start-up mode, the starter is fed directly from the batteries.

Manual start-up device test

After a start-up sequence (manual or automatic) or after a failure to start, the yellow LED (Fig. 2, pos. 22) recognised by the following indication is turned on: “OPERATE THE MANUAL START TEST BUTTON IF THE INDICATOR LIGHT IS TURNED ON”.

In this case, the corresponding button must be pressed (Fig. 2, pos. 23) to perform the start-up device test.

English

Pump demand

If the set pressure configured is not reached for at least one of the two pressure on/off switches, the green or yellow LED signals this (Fig. 2, pos. 34, 35). If these LEDs flash, this signifies that a configured dwell time has elapsed (see menu 1.2.5.1). Once the set dwell time has elapsed, the corresponding LED remains turned on while the pr essure switch is activated. The automatic start-up test run of the diesel motor is launched with a maximum of 6 start-up attempts. The running-in period (menu 1.2.2.1) as well as the pause time (menu 1.2.2.2) can be set using the software. After each start-up attempt, a switch to the other battery takes place. Any noncoupled pinions in the ring gear of the motor are detected. Connection is achieved by means of additional attempts.

Successful start-up of the diesel motor is signalled by the green LED (Fig. 2, pos. 3). This lights up when the measured rotation speed exceeds the threshold of the cut-in adjusted for “motor in operation” (menu 1.2.1.3). The LCD displays the symbol of the pump and the battery currently being charged with the remaining time before passing to the next charging system. The pinion for engaged starter is automatically disengaged. The diesel motor can only be manually switched off with the “OFF” button (Fig. 2, pos. 21), if at least one of the key switches is in the “Stop” position and if the change-over switch is not engaged. The green LED (Fig. 2, pos. 3) turns off if the cut-in threshold for “motor in operation” is not reached. The LCD displays once more the remaining time until passing to the other charging system.

Filling device

If the start-up tank level falls below 2/3 of its full level, then the “START-UP TANK MALFUNCTION” LED (Fig. 2, pos. 12) is activated.

If the LED flashes, this signifies that a follow-up time is elapsing (see menu 1.2.5.2). Once the set follow-up time has elapsed, the LED remains turned on while the float switch is activated.

This detection of a lack of water in the start-up tank launches the automatic start-up sequence of the diesel motor, with a maximum of 6 start-up attempts. The running-in period (menu 1.2.2.1) as well as the time between 2 attempts (menu 1.2.2.2) can be adjusted. After each start-up attempt, a switch to the other battery takes place. Any non-coupled pinions in the ring gear of the motor are detected.

A successful start-up of the diesel motor is signalled by a green LED (Fig. 2, pos. 3). This lights up when the measured rotation speed exceeds the threshold of the cut-in adjusted for “motor in operation” (menu 1.2.1.3). The LCD displays the symbol of the pump and the battery being charged with the remaining time before passing to the next charging system. The diesel motor can be manually switched off with the “OFF” button (Fig. 2, pos. 21), if at least one of the key switches is in the “Off” position and if the float switch is not engaged. The green LED (Fig. 2, pos. 3) turns off if the cut-in threshold for “motor in operation” is not reached. The LCD displays the remaining time before passing to the next charging system.

Monitoring of battery voltage

The cabinet is fitted with two battery chargers which are fed by the 230 V AC network. The chargers deliver 12 V DC or 24 V DC, depending on the type of starter to be fed. To maintain continuous service, the network voltage as well as the battery charges are constantly monitored.

Battery monitoring is ensured by the controller which constantly receives information from the two chargers. The chargers can signal the following malfunctions to the controller:

- a rupture of the wire, coupling or connection,

- a short-circuit,

- a battery malfunction,

- a connection voltage error. The malfunctions are analysed by the controller and displayed in the malfunction menu (Fig. 1, pos . 2). Furthermore, it is possible to adjust the minimal battery voltage in the menu 5.4.1.0. If this voltage is not

achieved by one of the connected batteries, an error message is displayed on the screen.

Installation and operating instructions: Wilo-SC-Fire Diesel A2P 13

English

Monitoring of motor start-up Once the pressure switch/float switch is activated, or after a successful manual start-up, the automatic start-up

cycle of the motor is l aunched. During the start-up phase, the controller monitors to ensure that the diesel motor is triggered. The diesel motor is triggered when the start-up pinion is engaged in the gear ring of the motor.

If the diesel motor is not triggered after the first attempt, an error message appears on the screen. After each start-up attempt, the other battery is used for the following attempt. After 6 unsuccessful start-up attempts, the process is interrupted, the yellow LED “ATTEMPT START-UP” turns on (Fig. 2, pos. 22), an error message is displayed on the screen and the malfunction signal contacts are active.

Duty cycling of the battery chargers

From the menu 5.3.1.0, it is possible to force the duty cycling of the active charger. To do this, go to the menu 5.3.1.0, accessible from level 3, change the value “Auto” and select “Man”. The value automatically reverts to “Auto”. The battery charger which was active has swapped. The duty cycling countdown has also been reset to 0.

6.2.2 Application of the switchgear Levels of access

8.1 Factory setting

The control is pre-set at the factory. The factory setting can be restored by Wilo customer service.

8.2 Rotation speed correction control

The motor rotation speed is fixed at the factory. To check it, the motor is to be started up by a manual function. Once the motor is running, increase the rotation speed by means of a portable tachometer and compare it to the rotation speed displayed on the screen. If the two rotation speeds match, no correction is required.

In case of significant difference, a further correction must be carried out. To do this, proceed as follows. Set the motor at a constant and known rotation speed. Enter this value in the menu 1.2.1.1 and confirm. Move on to the following menu item. In the menu 1.2.1.2, modify the setting by selecting “Start”, then confirm. Once the correction is performed, the message “Finished” is displayed on the screen. The rotation speed correction was successful and has been recorded. The motor can be switched off with the “OFF” button if at least one of the key switches is in the “0” position.

8.3 Rotation speed correction control

Commissioning at the place of installation requires the automatic device test of the diesel motor start-up. To do this, the fuel supply must be interrupted. In the menu 5.9.1.0, set “Start”, then confirm. Then push the button “CLEAR FAULT” (Fig. 2, pos. 20) in the following 10 seconds. 6 automatic start-up attempts thus take place. After 6 start-up attempts, the yellow LED (Fig. 2, pos. 22) signifies a failed start-up. The fuel supply must be restored and the motor must start up as soon as the button is pushed (Fig. 2, pos. 23).
