VACON® 100 FLOW
Application Guide
- 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.
7.
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.
8. 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.
9. 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.
