16.1 HYDRAULIC POWER UNIT: TO MONITOR MINIMUM FLUID LEVEL
WITH ADVANCE WARNING AND ALARM
In this example application, an advance warning should be given when the fluid
level reaches 30 cm and tank refilling should be started. An alarm should be
triggered if the fluid level drops below 10 cm and reset once the fluid level has
reached 15 cm again.
To achieve this as described in the example, the following settings must be
made in the ENS 3000 menu and the two switching points must be set as
follows:
