Installation
This chapter gives a step by step procedure for installing the Gilbarco interface unit. Switch
settings, cables, and so on will be discussed here in a context of their interactions and decisions
that must be made. Specific and systematic detail may be found in chapter three.
At the end of chapter two there is a short section on troubleshooting that pertains also to
sites that may already be in operation.
What to do first
1. Read and understand the Gilbarco manuals that apply to your pumps and CRINDs.
2. Verify that all CRIND and dispenser wiring is in place and complies with Gilbarco
standards.
3. Terminate two-wire loops from the pumps in a distribution box with a current loop
connection for the Gasboy CFN Gilbarco interface unit. (The pump loop is part
number C06691, and the Gilbarco interface unit is C05688.)
4. Terminate two-wire loops from the CRINDs in a distribution box with an RS485/
422 connection for the interface unit. (The adaptor is C06692; the cable is C06242;
both are C06326.)
5. For installations with CRINDS and eight or fewer pumps, you may build a dual
distribution box with one current loop input and one RS485/422 input. This is an
alternative to using two separate distribution boxes, one with current loop input,
one with RS485/422 input. Information on building such a distribution box is
found near the end of Chapter 3, page 34, Building a dual input mode distribution
box.
6. Install GSM and its power supply, within six feet of the Gilbarco Interface. Use
Gasboy cable C07248 to connect the GSM to Gilbarco Interface GSM port, adja-
cent to the RS485 connectors. This port may be marked “Unused port”.
7. Set up and connect the Site Controller according to the its start-up manual. If you
are using CRINDs, you must use a Site Controller II, and the software version must
be 2.0B or greater.
8. Verify that the Gilbarco Interface Unit contains firmware version 2.0 or higher, in
sockets U18 through U21.
9. Verify that the Gilbarco CRINDs have the Z-180 CPU board, Gilbarco part number
T177-64-G1S, revision C or greater, available as an upgrade for older CRINDs.
Things to watch out for
Correct the indicated CRIND two-wire address
For older CRINDs, CRIND jumper test diagnostic number 6, shows CRIND address applicable
to Auto Gas systems only. For all other systems including Gilbarco and Gasboy systems,
subtract one from the address shown there. See your CRIND manual for more information.
