1.1 Safety instructions
For a safe installation of a positioner, the following must be observed. The module shall only be
installed by qualified personnel who are familiar with the national and international laws, directives
and standards that apply to this product as well as all instructions in this manual.
The information in this user manual is subject to changes without notice.

2Application
Val Controls intelligent hydraulic positioner controls almost all hydraulic, linear, rotary, single-
return (SR) and double-acting (DA) actuators on the market.
Its compact design, with few moving parts, makes it very reliable. The flexible software calibrates
automatically, it contains intern safety surveillance together with several standard flow curves. A
special flow curve is defined very simple, and the positioner’s set point and deadband can be
adjusted from the user menu.
The positioner works by comparing the control loop signal with the position feedback, it then uses
control valve signals to operate the actuator/valve to the desired position. The control loop and the
transmitter loop signal is a 4-20mA signal with HART communication. The control valve signals
are powered through the 24VDC power supply and can supply valves up to 192W, 48W each. The
position feedback from the actuator/valve can be either a potentiometer or a 4-20mA loop powered
transmitter.
The power unit controller measures the pressure in the hydraulic system and controls a hydraulic
pump unit in order to keep the pressure within a specified range. When the pressure falls below a
user defined value, the positioner will turn on the pump and keep it running until the pressure has
reached the maximum defined value. Two pressure switches can be used instead of a pressure
transmitter.
It is possible to connect temperature and level transmitter/switches to monitor the hydraulic system
and shutdown the pump if a user defined value is reached.

3Installation guide
1. Connect all wires and make sure that all is connected correctly according to the hardware
manual/installation drawings.
2. Configure the unit using ValConnect or the display and keyboard
a. Configure the valve function, see 5.4.2 Advanced menu.
b. Configure position feedback, see 5.4.2 Advanced menu.
3. Auto calibrate the unit by pushing CAL button or using ValConnect, see 5.1.1 Automatic.
4. After a successful calibration the green indicator will light, see 4.4.6 Indicator.
5. If the red is light, there was an error during calibration. Press error on the keyboard and see
the error no. on the display or connect ValConnect and see what the error message is and go
to the manual to get an explanation on the error no. and how to solve it, see 7 Error no.

4User interface
The IHP comes with 4 different user interfaces which are described here.
4.1 Display, indicator and keyboard
To control and monitor the device, it is fitted with a graphical display, four buttons and two
indicators. When the lid is removed a TTL connector is available, for configuration via ValConnect.
A special connector cable is required.

4.5.4 MT control
The MT control can be used to operate the IHP through the window lid on the Ex D enclosure.
Position the MT pen above the sensors to emulate a button push. MT control is locked as default
and can be unlocked by touching → and then ←. The auto lock time can be set in the menu.
4.5.5 Status indicators
The functions of the seven indicators are as follows:
•ESD: The ESD input on the IHP is open
•Moving: The valve is opening or closing
•Closed: The valve is closed
•Open: The valve is open
•MT locked: MT control is unlocked
•Local: The IHP is in local mode and can be controlled by external open/close buttons
•Pump: The pump output is active
4.5.6 Indicator
The indicator lights will work as follows:
•Red indicator continuous: Glows when an error has occurred in the positioner
•Red indicator flashing: Calibration in progress
•Green indicator: Glows when there are no errors in the positioner
•Green indicator continuous: Initializing
4.5.7 Calibration button
