Nortel Networks 5000i - Manual (Page 27)

Electrical Requirements{ XE "Scanner installation: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. The table below lists the electrical requirements for the power operation
of the 5000i scanner.
Power Frequency Limits Voltage Limits Other Data
Standard 60 HZ ±5% 115V ±10% On 15 Amp., single-phase dedicated circuit.
Option 1 50 HZ ±5% 100 or 110V ±10% On 15 Amp., single-phase dedicated circuit.
Option 2 50 HZ ±5% 220 or 240V ±10% On 7.5 amp., single-phase dedicated circuit.
After you have verified the power and grounding requirements, perform the "Power Supply
Check-out Procedures."
Power Supply Check-out Procedures{ XE "Scanner
installation:Power supply checkout procedure" }
Perform the following checks with the scanner on but with the transport bed motor off
(unless otherwise directed by the procedure).
The 5000i scanner is equipped with four power { XE "Power supply:Checkout procedures"
}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){ XE "Power supply:+5V logic" }
• 914 022 751, +5V and ±15V Logic Power Supply
The +12V, 250W power supply produces +12.5V { XE "Power supply:12.5V logic" }for the
transport bed solenoids and hopper drive motors. The +12V, 200W, power supply produces
+12V boost voltage to pull the solenoids. The +5V power supply{ XE "Power supply:+5V
logic" } produces +5V for the read head LEDs. The logic power supply produces +5V, +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.
