Hydraulic Power Unit: Minimum Fluid Level Monitoring With Advance Warning And Minimum Temperature Monitoring - HYDAC ELECTRONIC ENS 3000 Notice D'utilisation

ENS 3000
18.2 HYDRAULIC POWER UNIT: MINIMUM FLUID LEVEL MONITORING WITH
ADVANCE WARNING AND MINIMUM TEMPERATURE MONITORING
In this example application, an advance warning should be given when the fluid level
reaches 30 cm and tank refilling should be started. The temperature also must not fall
below a certain limit. If, for example, a temperature of
20°C is reached, a "stop" signal will appear. Furthermore, the temperature will be
transferred to an SPS card as a 4 .. 20 mA signal.
For realization of this function as described in the example,
the following settings in the menu and on the switching points of ENS 3000 must be
effected:
