• Maintenance of radio:
  • To perform preventive maintenance of TRC 5100 radio (oscillator tuning).
  • To perform corrective maintenance of TRC 5100 radio.
    - To test complete TRC 5100 radio (close configuration).
    - To detect faulty modules.
    - To test and troubleshoot modules (open configuration).
    - To perform power measurement of TRC 5100.
    - To load embedded software.
  

• Control of accessories:
  • To test and troubleshoot antenna.
  • To check functionality of handset/headset.
  • To check functionality of battery charger.
  • To perform battery performance parameters (option BPTB).
  • To test and troubleshoot radio watertightness (option WTB).
  

Intermediate Level Maintenance (ILM) operations consist of preventive and corrective maintenance. In corrective maintenance, the repair of failed equipment is done by replacing failed interchangeable sub-assemblies, modules or PCBs according to the procedure defined for each equipment. Complete re-calibration and check-up of equipment are done after any intermediate level operations. The failed sub-assemblies or modules or PCB are sent to depot level.

ILTB 01 (Intermediate Level maintenance Test Bench) is a test bench to perform ILM of TRC 5100 radios and its accessories such as battery, battery charger, antenna, handset and headset at IL workshop.

ILTB 01 Composition

ILTB01 consists of:
• 3.1. Specific test equipment:
  • Main Test Bench (MTB) composed of an enclosure grouping all electronics and mechanics interface for radio and modules, as far as all necessary cables.
  • Radio Maintenance Software (RMS).
  • A set of specific tooling for assembly and disassembly.
  

• 3.2. Standard equipment:
  • A PC running WINDOWS English OS (WINDOWS 2000, XP, NT).
  • Standard Measurement Equipment.
    - Frequency meter (100 MHz range, accuracy 10-7, 50 Ω input).
    - Digital Multi-meter.
    - SWR Power Meter (< 225 MHz, 200W power max).
  • A set of standard tools.
  

• 3.3. Reference equipment:
  2 TRC 5102 radios, 2 antennas, 2 batteries, 1 battery charger, Handset and/or headsets, 1 Cloning cable.
Nota : Item 3.2 and 3.3 can be either delivered by STE with the bench or procured directly by customer.

Options

ILTB may include in option:
• Battery Performance Test Bench (BPTB):
  
  • This bench allows automatic test to measure battery capacity and other electrical performances. This bench is recommended to control the status of batteries all along their cycle life.
  • This test bench consist of an electronic interface box for 2 batteries, a Data Acquisition Card for PC and a Battery Performance Measurement Software (BPMS).
  • BPTB 01 is for Nickel Cadmium batteries (ALI 124 or ALI 124B) • BPTB 02 is for Polymer Lithium-Ion batteries (PLI 01)
  

• Watertightness Test Bench (WTB):
  • Military radios are designed to be watertight (MIL STD 810E ) to ensured reliability under environmental constraints and usage (immersion, water splash, fungus, salt atmosphere,..). Opening and closing radios for purpose of maintenance will required to keep this radio in good watertightness condition. Ignoring this process may cause long term failure of the radio.
  
  
  • WTB is a bench to measure air leakage enabling user to control watertightness due to improper assembly or due to gasket worn out.
  • This test bench consists of a Leakage Tester (programmed), a compressor, a mechanical adapter with radios.
