Hydraulic Power Unit (HPU) Controller
What is a Hydraulic Power Unit (HPU) Controller?
The HPU feature can control a hydraulic pump to keep the pressure in the system within a specified range by monitoring the pressure in the system.
By monitoring the hydraulic system, the HPU controller will shut down the pump if the temperature of the hydraulic oil is too high or if the level of the hydraulic oil in the tank is too low.
The Hydraulic Power Unit (HPU) control is a built-in software feature for Val Controls Intelligent Hydraulic Positioner (IHP24) and the Intelligent Diagnostics Controller (IDC24). The Controller can be used as a dedicated HPU controller or be combined with Partial Stroke Testing or positioning features.
The controller comes in enclosures fit for all types of environments and industries.

How it works
Communication
The HPU Controller comes as standard with the following control and communication options:
- 4-20mA with HART
- Modbus
Pressure, temperature & level output
The HPU Controller accepts the following signal types:
- 4-20mA - 2-wire sensor
- Switch input
Control modes
The HPU Controller is always on auto-mode when in use.
During set-up and troubleshooting it is possible to use the following control modes:
- Always on/off
- Manual
- Local control panel
