VACON® 100 FLOW
Application Guide
This parameter specifies the operation mode (master or slave) in the Multi-pump system. The drives that have the start command
and the PID feedback signals connected, can operate as the master drive in the Multi-pump system. If there are many drives in the
Multi-pump system that have all the signals connected, the drive with the lowest Pump ID Number (P3.15.3) starts to operate as the
master.
11.17.3 Interlocks
The interlocks tell the Multi-pump system that a motor is not available. It can occur when the motor is removed from the system for
maintenance or bypassed for manual control.
11.17.3.1 (ID 1032) Pump Interlocking
Location in the menu: P3.15.5
Use this parameter to enable or disable the interlocks. Interlock signal tells to the Multi-pump system if the motor is available or not.
Interlock signals are given with DI signals. To use the interlocks, enable the parameter P3.15.2. Select the status for each motor with
a digital input (the parameters from P3.5.1.34 to P3.5.1.39). If the value of the input is CLOSED, that is, active, the Multi-pump logic
connects the motor to the Multi-pump system.
11.17.4 Feedback Sensor Connection in a Multi-pump System
To get the best precision and redundancy in the Multi-pump system, use the feedback sensors for each drive.

Illustration 93: Wiring of the Feedback Sensors for Each Drive
Same sensors can also be used for all the drives. The sensor (transducer) can be supplied by a 24 V external supply or from the
control board the drive.
