6. CHECKS AND CALIBRATIONS
6.1 POWER SUPPLY BOARD 391110
Disconnect all output cables from the board (J2, J4, J5). Connect the
PULSAR2 to the mains and switch it on.
Verify, with a digital voltage meter, the output voltages of the board on the
J2 connector:
Pin 1, Pin 2 GND pwr (Power Ground)
Pin 3 +24 ± 0.5V (Power)
Pin 8 (Power fail) +3.3 ± 0.2V (Signal)
Pin 9 +5 ± 0.15V (Signal)
Pin 10 -12 ± 0.5V (Signal)
Pin 11 +12 ± 0.5V (Signal)
Pin 12 GND (Signal Ground)
Switch the PULSAR2 off and re-connect all the output connectors (J2, J4,
J5) to the Power Supply Board.
6.2 CONTROL BOARD 393200
Check of reference voltages
-Connect multimeter between TP1 and GNDs
