This is the software upgrade procedure to be followed for all bulk meter
registers and all pumps with a C4000 other than those with FUTRA
software.
1. Ensure, before working on the pump, that anti-static precautions are
taken (i.e. wearing of wristband with earth strap).
2. Gain access to C4000 Processor Board and record all set-up data by
accessing the configuration (K-Factor) switch and the parameter
switch, this includes recording the comms dipswitch settings. Data set-
up to include:
3. K factor 'F '
4. No flow delay 'n'
5. Pre-set cut-off margin 'PCut'
6. Density Factor 'dSF' (CNG only)
Specific density 'SPG' (LPG only) Flow rate 'FLO' 'r' (some
bulkmeters only)
Temperature 'E' (bulk meter or LPG only)
L Cut 'L' or 'LCUT' (bulkmeter only)
H Cut 'H' or 'HCUT' (bulkmeter only)
F Cut 'F' or 'FCUT' (bulkmeteronly)
Set resolution 'Sr'
Configuration 'C '
'b' Settings
Price 'Pr' or 'P'
Density 'd' (bulkmeters only)
Pump number 'Pn'
Sequencing Rate 'SE9' (CNG only)
Access code 'A' (comcard or CWIDKey Basic dispensers only)
7. Electronic and mechanical totals should also be recorded.
8. In the case of 'Comcard Basic', 'Compin' (Mining), or 'CWIDKey Basic'
systems, a printout of card/pin/key totals must be obtained before
changing software. This printout will also give card/pin/key validation
status. If no printer is available, use Scrolling Tote option (refer
Totalisers (see page 57)).
9. The above steps are taken to safeguard against software
incompatibility causing loss of information.
10. Turn off power.
11. Remove software EPROM (removable chip labelled C4000 PXX or XX-
X-XX:XX.X) using an EPROM extractor. (See Figure 1 for the location
of the EPROM.)
12. Plug in new software EPROM, being careful that the dimple is at the
correct end of the socket. (i.e. software chip dimple to base dimple).
Also that all the legs are correctly located in the socket (see diagram
below).
13. Turn on power.
14. Check that the data recorded in Steps 2 and 4 is still present, if not re-
enter.
15. Check the electronic totals, if not as before then give 'before' and 'after'
totals to relevant people on site.
16. Ensure that the status of cards/pins/keys, on 'Comcard', 'Compin', or
CWIDKey systems, are as before. If they are different in any way,
ensure that the relevant people on site receive 'before' and 'after'
