Installation Guide for the OpScan iNSIGHT 70 Scanner
Electrical Requirements
The steady-state line-to-neutral voltage should be maintained within -10% to +5%
of the normal rated voltage. The short term and long term frequency variations
must be maintained at less than ±5% of the specified power line frequency as
measured at the input power side of the scanner when it is powered on. Table 2-3
lists the electrical requirements for the power operation of the OpScan i NSIGHT
70 scanner.
After you have verified the power and grounding requirements, perform the
"Power Supply Check-out Procedures."
Power Supply Check-out Procedures
Perform the following checks with the scanner on but with the transport bed
motor off (unless otherwise directed by the procedure).
The OpScan i NSIGHT 70 scanner is equipped with four power supplies. They are:
•
914 022 769, +12V 250W Power Supply
•
914 022 264, +12V 200W Solenoid Boost Power Supply (Unregulated)
•
914 022 744, +5V Power Supply (LEDs)
•
914 022 751, +5V and ±15V Logic Power Supply
The +12V, 250W power supply pr12.5V for the transport bed solenoids
and hopper drive motors. The +12V, 200W, power supply pr12V boost
voltage to pull the solenoids. The +5V power supply pr5V for the read
head LEDs. The logic power supply pr5V, +15V and -15V logic power for
the cameras and various scanner PC boards.
The logic power supply and the LED power supply require periodic check-out
and adjustment. In addition, the 12V, 250W power supply needs to be adjusted to
12.5V. If any voltage is outside the proper range, adjust the outputs as described
in the following "Logic Voltage Checkout Procedures." If you cannot adjust the
output, replace the power supply. There are no field repair procedures for any of
the scanner's power supplies.
