TANK MONITORING SYSTEM (OPTIONAL)
1. Verify that the tank monitoring system is correctly connected to the Site Controller according
to the Site Controller II or Islander II Installation Manual. Connection can be made vai RS-
485, RS-232, or RS-422.
2. If connected via RS-485, make sure the RS-485 modular cable (C05670) is connected from
the RS-485 junction box to the RS-232 to RS-485 converter assembly (P/N C05897). Then
verify that the RS-232 cable (P/N C04549) is connected from the converter assembly to the
correct port. See your tank monitoring system documentation for specific wiring
requirements.
CURRENT LOOP INTERFACE (OPTIONAL)
1. Verify that the current loop interface unit is located in an office-type environment and is
correctly installed according to its installation sheet.
2. Make sure the special RS-485 communication modular cable is directly connected between
the current loop interface unit (slot labeled RS422) and the RS-485 junction box using the
appropriate RS-485 modular jacks.
NOTE: The modular cable from the current loop interface unit to the RS-485 junction box is
GASBOY P/N C04500 (cross) modular cable. Other devices (Site Controller,
Console to junction box, etc.) can use GASBOY P/N C05670 (1:1 cable).
3. Verify that the two wire current loop communications is correctly wired to the distribution box
according to the Gilbarco Interface Unit Installation Manual, C01745.
FUEL POINT COMPONENTS
1. Verify that all the Fuel Point components are installed according to the applicable Fuel Point
installation manuals (listed in section 1).

separate from non-intrinsic safe wiring.
