Select Signals connected, if the start and the PID feedback signals (the pressure sensor, for example) are connected to

the drive.

Select Start signal only, if only the start signal is connected to the drive (the PID feedback signal is not connected).

Select Not connected, if the start or the PID feedback signals are not connected to the drive.

Set the ID number of the pump.

Go to parameter P1.35.15 (Quick Setup Parameter Menu).

The same parameter is in the menu Parameters -> Group 3.15 -> P3.15.3.

Each drive in the Multi-pump system must have an ID number that no other drive has for the correct communication

between drives. The ID numbers must be in a numerical order and start from number 1.

The drives, which have a PID feedback signal connected, have the smallest ID numbers (for example, ID 1 and ID 2). It

gives the shortest possible start-up delay when doing a power-up of the system.

Configure the Interlock function.

Go to parameter P1.35.17 (Quick Setup Parameter Menu).

The same parameter is in menu Parameters -> Group 3.15 -> P3.15.5.

By default, the interlock function is disabled.

Select Enabled, if the interlock signal is connected to the digital input DI5 of the drive. The interlock signal is the digi-

tal input signal that tells if this pump is available in the Multi-pump system.

Select Not Used, if the interlock signal is not connected to the digital input DI5 of the drive. The system sees that all

the pumps in the Multi-pump system are available.

Examine the source of the PID setpoint signal.

By default, the PID setpoint value comes from parameter P1.35.9 Keypad Setpoint 1.

If necessary, change the source of the PID setpoint signal with parameter P1.35.8. Select the analog input or Fieldbus

Process Data In 1–8, for example.

The basic settings of the Multi-pump system are completed. Use the check list also when configuring the next drives in the system.

11.17.2 System Configuration

11.17.2.1 Single Drive Configuration

The Single drive mode controls a system of 1 variable speed pump and the maximum of 7 auxiliary pumps. The internal PID control-

ler of the drive controls the speed of 1 pump and gives control signals with relay outputs to start or stop the auxiliary pumps. Exter-

nal contactors are necessary for the switch of the auxiliary pumps to the mains.
