RELAY AND ETHERNET CONNECTION
NOTE:
7/8" max length Ethernet connector recommended. The Ethernet connection has a sharp cable bend angle and
reducing the connection terminal length reduces this problem.
NOTE:
To maintain pump IP protection, the network cable should be pulled through the gland inlet and then crimped to a
connector.

14.CONTROL MODES AND PRIORITIES
14.1 Setting Priority
Several signals will influence the pump operation. For this reason, settings have priorities as shown in the table below.
If two or more functions are active at the same time, the one with highest priority will take precedence.
Examples:
• Stop on the pump display panel will stop the pump, regardless of external set point.
• If External Run input is inactive, the pump cannot be started over Modbus, but can be
set to max RPM on the display panel.
