2.1.2.9 LEVEL INPUT
The Level input (terminals 41-42) is meant to monitor an external level or flow measurement and
provide the necessary feedback in the event of a high and/or low level/flow event. Configurable as
disabled, digital input or 4-20mA signal through the user interface; the level input can be connected to
either a switch or transmitter.
In digital mode the level input can be used a wait, warning or an alarm when the contact opens. This
can be connected to a low or high trip switch depending on the application.
In 4-20mA mode the level input is used in conjunction with the low-trip and high-trip modes. These
modes are independent of one another and can be configured as either a wait, warning, or an alarm.
This input is intended to be connected to a level transmitter.
The following table outlines the behavior of the Level Input:
