MAINTENANCE
This section provides detailed information about the electronics and electrical components inside the Site Master, which consists of
board specifications, input and output descriptions, wiring connections, and test points if available. The electronics described in this
section control incoming AC power, point of sale communication, data communication, and displays. For information on parts, please
refer to the
Parts Section .
The service information in this manual is intended for Bennett trained technicians. All technicians must be aware of all safety instructions
provided on page iii. If you are not a Bennett trained technician, please contact Bennett Technical Support at 1-800-423-6638 for training
information.
FUSE BOARD (P/N 130809)
Fuses are used to protect the SBC2 Electronics and Power Supply from incoming AC voltage and for power
traveling throughout the system. DC voltages then are sent over to the SBC2 Board through a multi-pin
conductor from connector [J1] of the Power Board to connector [J2] on the SBC2 Board. The standard glass
body fuses are located on a fuse block cartridge as shown in
Figure 3.1 .

F1 and F2 = +24 Volts

F3 and F4 = +12 Volts

F5 and F6 = +5 Volts
COMPONENT DESCRIPTIO N
The following is a description of the connections to the terminal strips of all the connections on the fuse board as shown in Figure 3.2 .
J1 Power Board
A 12-position header input connects to the power board for +24VDC and +12VDC.
J2 SBC2 Electronics
10-position header input connects to the SBC2 Electronics for Module Power and Module RS-485 Payment Communication.
REPLACING FUSES
CAUTION: Replace fuses only with fuses of the same rating.
If the incoming AC voltage blows a fuse on the power board, check for cross phasing. If a cross-phasing condition exits, correct the
problem before replacing the fuse. Troubleshoot the incoming power prior to replacing the fuse.
Fuse Part Number Description
F1, F3, F5 130976 3.15 Amp, Slow
