Open Circuit Controls
Objectives
At the end of the course, trainees will be able to:
- Read a hydraulic diagram.
- Understand how a complete hydraulic system works.
Program
1. HY3 SAFETY: IDENTIFY THE SAFETY POINTS FOR INTERVENTION BY ANALYSING THE DIAGRAM (LOCKOUT MANAGER)
- Lockout – Removal of lockout.
2. REFRESHER ON THE DIFFERENT TYPES OF CIRCUIT
- Open circuit – Closed circuit.
3. ANALYSIS OF TYPICAL CIRCUITS / OPEN CIRCUITS
- Simultaneous movements: Multiple pumps – Flow dividers – 3-way flow regulators (priority and excess flow).
- Setting the speed: Chokes – Flow regulators.
- Maintaining speed under variable load: Constant pressure and flow regulation (Load-Sensing) – Flow Sharing regulation combined with power regulation.
- Effort control: Progressive pressure distribution – Constant power control.
- Drive load control: Safety – Balancing, brake, parachute and rupture valves for hoses.
4. ANALYSIS OF TYPICAL / CLOSED CIRCUITS
- Booster – Scavenge – Oil exchange – High-pressure (HP) or anti-shock valves – Flow cancellation – Servo control.
5. READING DIAGRAMS
- Methodologies.
- Identification of symbols and circuits.
- Analysis of the machine’s operating phases.
- Interpretation of pressures and flows.
6. TROUBLESHOOTING BY SCHEMATIC ANALYSIS
- Definition of the symptom (knowing how to ask the right questions).
- Formulation of hypotheses (possible causes).
- Principles for eliminating assumptions (Visualisation, Permutation).
- Mistakes to avoid.
- Diagnostic.
- Fault analysis on application diagrams.

of principals would recommend IFC TRITECH as a training organization.
Quality
This is the percentage of satisfaction obtained after consulting all 2023 trainees on the quality of our training courses.
Pedagogy
This is the score obtained by IFC TRITECH when participants were asked about the suitability of teaching resources for their inter-company training.
Our testimony
We call on IFC TRITECH for training in electricity and hydraulics, so that our technicians can develop their skills in an agile way. IFC TRITECH also provides us with tailor-made training on our runway equipment, which incorporates specific and complex technologies, both in its training centres and on our premises.
All these factors have made IFC TRITECH the preferred training organisation for Air France's ramp equipment division for over 20 years!
For more than 10 years, we have trusted the IFC TRITECH group with our training needs. Their skilled trainers are passionate about their work, which is reflected in the quality of their training courses. Thanks to them, our Loxam technicians develop their knowledge and performance in the field.
For over 20 years, IFC and TRITECH have been the benchmark in the field of hydraulics and lubrication training.
I have met passionate trainers who have enabled me to develop my skills in these areas.
Together with them, we have developed training courses for my employees in the maintenance of unique and complex tools.
