Model 512.04 Hydraulic Power Unit
Introduction
7
Electronics
The HPU has basic controls to turn it on to low pressure or high pressure
and to turn it off. The HPU includes an
Emergency Stop
switch that is
connected to the interlock chain of your test system.
A hydraulic interlock can be generated by the hydraulic power supply if
one of the following occurs:
•
Low hydraulic fluid level
•
High hydraulic fluid temperature
•
Dirty hydraulic power supply filter (optional)
