·         One turntable, turntable with eight working station,
 
6)    Generating Bar code (Ink Jet Unit):
·         Bar code should be generated and printed on breaker using bar code printer. It shall be 1st stage, so that individual breaker shall be traced in each testing stage for Data acquisition
·         When scanning the breaker with bar code scanner all test results should appear.
·         All breakers barcodes and results saved on PC database to maintain traceability at any time.
·         Should be possible to put individual barcode OR Batch code on product. Ability to set and change codes as per requested.  Code to appear at the bottom of breaker.
·         Barcode is 2D , 10x10 mm

7)   Tripping Force test
·         On testing station the first operation is to switch on/off product for one time to ensure tripping mechanism is in good condition.
·         Cylinder will push breaker to on Position, and pin connected to stepper motor will trip breaker from side.
·         Operation will happen 3 times, anytime breaker fail, we need to reject the breaker.
·         Four parallel triping force stations

8)   Unscrewing:
·         Unscrewing of terminals
·         fou product together ;
·         screws is four sets
 
9)   Magnetic Test:
·         Power source: current capacity: 10~1000A accuracy ≤±5%; duration of input test current shall be 200ms maximum and should be settable in PC; Current should be multiple of breaker rating and it should be settable.  , Waveform to be displayed on oscilloscope whenever required. Tripping time & Tripping current both to be displayed on suitable meters.
·         Electrode Contacts should be silver brazed.
·         Statistical data easy to be shown on screen and could be printed.
·         Six product test together
 
10)   HV Test:
·         Voltage source : 0~5000V adjustable testers of high leakage current Precision, Leakage Current capacity 100ma continuous, short in response time and very stability.
·          Dielectric test between two terminals in OFF condition and Terminal & Base bottom in ON condition to be tested each test for 1 sec. Leakage level for detection of fault shall be   at 2ma settable at different level on instrument.
·         Overall Accuracy better than 5%.
·         Statistical data easy to be shown on screen and could be printed.
·         Testing will be for breaker in On Position on V shape between poles.
·         Testing will be for breaker in Off Position between breaker terminals.
·         four product test together
 
11)   Thermal Test:
·         Alfanar MCB is having predefined one current value for each MCB rating (2.5 In for the thermal) so Alfanar will provide the current value.
·         In Thermal test, Temperature sensor is required to change tripping band or current value as per room temperature
·         Technology parameter of constant power: D.C Source with following Specs
§  Overall Accuracy better than 0.2%
§  Repeatability better than 0.1%
§  Source Make: TDK Lamda 'GEN 20-250'
§  Digital type
·         Electrode Contacts should be silver brazed.
·         Statistical data easy to be shown on screen and could be printed.
·         Machine will take out automatically failed breakers and arrange them in different groups, 1 sec Low, 2 sec Low, 1 sec High, 2 sec High etc
·         eight parallel triping force stations
 
 
12)   Pad Printing Unit:
·         Machine will be suitable for 1P 63A 3 breakers in one shot
·         Machine will be suitable for 2P 63A 1 breakers in one shot.
·         Machine will be suitable for 3P 63A 1 breaker in one shot.
