MultiSmart Installation & Operation Manual
18 Supply Protection
The Pump Control/General I/O Board monitors the single or three phase supply through the “Mains Voltage
Monitoring” inputs. Single and 3 phase power supplies can be monitored by the MultiSmart. The voltage is
constantly measured and is used to detect the following conditions:
• Under Voltage
• Over Voltage
• Phase Imbalance (or Phase Failure)
• Phase Rotation
Supply protection is usually automatically enabled when the setup wizard is completed.
NOTE:
The Under Voltage threshold is temporarily ignored during the starting of a pump.
