DIAGNOSTIC CONTROLLER

IDC24

The IDC24 range offers the best in performance and user-friendliness, combining these in a very compact enclosure.

To be used for valve testing and operation. It has an integrated microprocessor with very flexible software, so the controller fits almost any hydraulic and pneumatic, rotary and linear, double acting and spring return actuator on the market.

 

IDC24-A

This model is for customers with very high demands for performance and connection possibilities. This
unit is very flexible and can be configured to almost any customers needs and can be easily expanded,
e.g. with a backup battery or other advanced features. The IDC24-A is intended for already installed
systems or customers who have their own housing and installation

The IDC24 Advanced is an affordable hydraulic positioner which offers:

• Partial Stroke Test
• Online Valve Monitoring
• Valve Diagnostic Controller
• Full Stroke Testing
• Solenoid Valve Testing

• Easy to install and configure
• Automatic intelligent calibration
• Intelligent diagnostic
• User-friendly menu
• Flexible and configurable
• Ultra low power design

 

IDC24-AF

The Advanced Flameproof model is designed around a SS316L flameproof enclosure.

The IDC24-AF hydraulic positioner offers:

• Partial Stroke Test
• Online Valve Monitoring
• Valve Diagnostic Controller
• Full Stroke Testing
• Solenoid Valve Testing

IDC24-F

The IDC24-F hydraulic positioner offers:

• Partial Stroke Test
• Online Valve Monitoring
• Valve Diagnostic Controller
• Full Stroke Testing
• Solenoid Valve Testing

Note that the IDC24 F is build as a non-contact position transmitter.

How it works

The IHP24 uses Solenoid Operated on/off Valves, SOV, to move the actuator to the requested set point. It has 4 or more outputs to control SOV’s depending on the model. The IHP24 is designed so it can use any solenoid valve on the market. The unit will automatically adapt the regulator to the performance of the complete system, during an automatic calibration. The desired position of the valve is sent to the IHP24 via the 4-20mA control loop or a communication protocol. The actual position is measured by the IHP via a potentiometer or a 4-20mA sensor. The set point and position signal is compared and the actuator is moved to the requested position.

CONTROL

Model AF and A has the following features in the user interface:

• Graphical display
• 4 button keyboard
• Status indicators:
          - Open/closed
          - ESD
          - Local
          - Pump
          - MT locked (only AF)
          - Test pass
          - Test fail
          - Test in progress

BASIC DIAGNOSTIC

Basic diagnostic can be performed directly on the IDC24 display and keyboard. For more detailed
diagnostic, the test data must be transferred to Val Controls Diagnostic Centre.

The IDC24 can perform the following test:

• Partial stroke test – PST
• Full stroke test – FST
• Solenoid valve test – SOT
• Emergency shutdown test - EST

The IDC24 makes a valve signature during the following tests:

• Partial stroke signature
• Full stroke signature
• Emergency stroke signature

GRAPH & SOLUTIONS

All graphs can show valve position and actuator pressure. This makes the IDC24 able to find parameters
that can show the condition of the valve. Some of the parameters, which can be used to detect possible
problems are:

• Breakaway time
• Travel time
• Breakaway pressure

Some of the problems that the IDC24 can be used to identify includes:

• Slow reacting or stuck solenoid valves
• Slow moving or stuck valve
• Increased stem friction
• Broken spring in actuator
• Long reaction time

VAL CONTROLS DIAGNOSTIC CENTRE

Val Controls Diagnostic Centre for evaluating partial stroke, full stroke and solenoid test.
By using Val Controls Diagnostic Centre it is possible to:

• See test results and valve signatures
• Compare valve signatures
• Live control and monitoring of the valve system
• Generate test reports

Each recorded signature can be examined graphically by the operator. The recorded signatures can be
selected from a list based on the date and time it was recorded.
Up to six signatures can be visually compared by selecting them from the lists. This enables the operator
to see how the system has performed compared to earlier tests. If the graphs evolve in one direction
over time, the report indicates wear in the system.

The IDC24 records several performance information during the tests. Together with the valve signatures
these can be compiled to test reports. The reports are easy to customise with the needed data as well as
logo and customised header and footer
