8.2 COMBO function 

In the “Installer parameters” menu it is possible to enable the COMBO function that allows serial communication between up 

to 8 E-drives, each one connected to a pump.  The operating principle (switch on/off) of pumps is similar to as stated in 
chapter 8.1. 

To achieve the COMBO function in a system consisting of several interconnected E-drives, use a pressure sensor connected 
to each E-drive. The value of the 

set pressure

 is communicated to the slaves via the serial port. 

To prevent the shutdown of the system due to pressure sensor failure, connecting a 2nd pressure sensor to the  E-drive; 
make sure that the two pressure sensors are identical. 
Remember to perform the offset operation of the sensors in each E-drive  (Installer Parameters menu) . 
As a further help, you can connect another two DOL pumps to the E-drive Master to cover additional water demand; they 
will be operated only when all the COMBO pumps are already in

 

operation. 

 

RS485 serial connection 

 

E-drive

’s communication i

s made through a private protocol using the RS485 port. Each E-drive must be connected to each 

other by using a tripolar cable (0,5 mm

2

) wired on S+,S-,G pins on control board.

8.2 COMBO функционал

В меню «Параметры установщика» можно включить функцию COMBO, которая обеспечивает последовательную связь между 8 устройствами E-drive , 
каждый из которых подключен к насосу. Принцип работы (включение / выключение) насосов аналогичен указанному в Глава 8.1.

Для достижения функции COMBO в системе, состоящей из нескольких взаимосвязанных электронных приводов, используйте подключенный датчик 
давления на каждый электронный диск. Значение установленного давления передается ведомым через последовательный порт.
Чтобы предотвратить отключение системы из-за сбоя датчика давления, подключите второй датчик давления к электронному приводу;
убедитесь, что два датчика давления идентичны.
Не забудьте выполнить операцию смещения датчиков в каждом электронном приводе (меню «Параметры установщика»).
В качестве дополнительной помощи вы можете подключить еще два насоса DOL к E-drive Master, чтобы покрыть дополнительную потребность в воде; 
Oни будут работать только тогда, когда все насосы COMBO уже работают.

Мастер настройки

1. Подайте питание на E-drive.
2. Если это еще не сделано, выполните первоначальную настройку, как описано в главе 6.2.
3. Начальный экран  показан:

Последовательность соединения RS485

Связь с E-drive осуществляется по частному протоколу через порт RS485. Каждый электронный диск должен быть подключен к 
другому с помощью трехполюсного кабеля (0,5 мм2) подключеного к контактам S +, S-, G на плате управления
