PHYSICAL SYSTEM LAYOUT
When verifying physical system layout, be sure power to the system has not been applied
and all power is off. All wiring and conduit runs must also conform with the National Electrical
Code (NFPA 70), the Automotive and Marine Service Stations Code (NFPA 30A), and State and
Local Electrical Codes. See the Site Controller II Installation Manual, C01918, for more guidance.
SITE CONTROLLER
1. Verify that the Site Controller is located in an office-type environment and correctly installed
according to the Site Controller II Installation Manual.
2. Verify that all data communication cables located on the back of the Site Controller are
correctly installed according to the Site Controller II Installation Manual. The Site Controller II
has four RS-232 ports. All direct connect RS-232 cables over 15 feet must be installed in
metal conduit separate from any AC wires.
Port 0 is used for communications to a CRT terminal (and/or logger); Port 2 is used for
communication through a modem or to a computer. Ports 1 and 3 are additional and can be
programmed according to the application. A logger eliminator must be connected to port 0
when a logger is not used.
RS-485 communication cables (C05670, 8-foot modular cable similar to a telephone cord)
must be installed as follows:
ISLAND PORT modular cable must be directly connected to either modular jack of the black
RS-485 junction box.
NOTE: If using Tokheim DPT's, consult Gasboy's Technical Service.
CONSOLE PORT modular cable must be directly connected to the modular jack on the rear
of the Check Point console labeled Site Controller or to the converter if connecting to a Profit
Point. See the Site Controller II Installation Manual for remote console wiring considerations.
3. If fan filter unit is installed, verify that customer knows how to clean and/or change the filter
on a regular basis. Otherwise, do not install the filter. See the Site Manager's Manual,
Preventive Maintenance section.
ISLANDER
1. Verify that the Islander is installed to allow adequate clearance for system maintenance. A
minimum of 14 inches of clearance from the rear of the head of the unit must be provided to
allow the rear door to open. A minimum of 18 inches is required between the post and any of
the pumps or dispensers. This clearance meets the NFPA 30A and NFPA 70 requirements.
