APPENDIX F
WEIGHT AND MEASURES SECURITY PLUG
F-1. GENERAL
This appendix provides instructions for installing the Weight and Measures Security Plug (see
Figure F-1) in Gasboy Site Controllers.
In order to comply with W&M regulations and since pulses to volume conversion factor is defined
in FCC, the security plug connected directly to OrCU via RS-232 port, prevents miscalibration of
Mechanical Pumps.
NOTE
Since RS-232 port is used, remote communication
via dial-up modem will not be supported.
Once the W&M security plug is detected, fuelling from mechanical pumps is allowed but
modification of the pulse factor will be disabled (current value is shown).
This procedure should be performed in each controller (Islander PLUS, CFN PLUS, FTC, TopKAT
PLUS) that commands a mechanical pump.
NOTE
Controllers configured for mechanical pumps
become inoperable in cases where the W&M
security plug is missing / removed.
