Section 2. Controller Operation
18 - Features
This section describes the controller features for 1900e series of pumps.
The controller is used for various remote control applications, including:
• Remote on/off
• Analog 0 - 10 V voltage control
• Status relay feedback
There are several possible connection configurations. Not all functions can
be used simultaneously.
• on/off + 0 - 10 V + relay output
