  • All work must be done by qualified personnel.


Chapter 3: Electrical Power

  • Load: 4 kW / 10 A max.

  • Voltage: 230 V ± 5%.

  • Frequency: 50 Hz.

  • Working temp: –20 °C to +60 °C.

  • Ensure all electrical work is performed by certified technicians.


Chapter 4: Pneumatic & Hydraulic Setup

Pneumatic

  • Air: 7 bar input / 6 bar working.

  • Hose: 8 mm (10 bar rated).

  • Main valve: SMC ITV 1050.

  • Regulator: SMC IR 2000-02 BG-A.

  • Reservoir: 3 L.

  • Operating temp: –20 °C to +60 °C.

Hydraulic

  • No hydraulic components. Machine runs on pure air pressure.


Chapter 5: Mandatory & Prohibition Signs

Safety Labels Include:

  • Electrical hazard (single & three-phase).

  • Earth connection warning.

  • High voltage & hot surface warnings.

  • Rotating/moving parts hazards.

  • Mandatory use of gloves, shoes, and PPE.

  • Reference manual before operation.


Chapter 6: Operator Responsibilities

  1. Operators must be trained by OEM.

  2. Read full user manual before operation.

  3. Verify air & electrical connections.

  4. Mount injector properly before testing.

  5. Handle control panel carefully.

Control Panel Functions:

  • Mains ON/OFF

  • Pump ON/OFF

  • Light control

  • Dummy (future use)


Chapter 7: Safety Information

  • Always disconnect main power before opening panels.

  • Only authorized personnel may operate main isolator.

  • Emergency Stop: Provided on control panel top — immediately stops machine.


Chapter 8: Operating Instructions

Test Modes

  • Dynamic Test: 5–50 Hz, 200–650 KPa, measures flow rate (gm/pulse, cc/sec).

  • Static Test: Injector fully ON, measures max output at fixed pressure.

  • Leak Test: Checks injector sealing at static pressure (200–650 KPa).

System Overview

  • Software: LabVIEW 2017 on Windows 10.

  • Data acquisition: NI-6001 USB card.

  • Controlled via PC, keyboard, and GUI interface.
