5.5 Installing Communication Interfaces Installation
5.5.3.1 Pulse Input Wires
The dispenser outputs pulses to the system by means of the pulser unit, installed in accordance
with manufacturer instructions. The pulse rate per volume (liter/gallon) is determined by the
pulser unit. It is programmed as a “factor” by the Head Office controller.
5.5.3.2 Handle Status Input Wires
The handle signal is used to signal to the system that the pump is in “In Use” mode. When the
dispenser handle is lifted this contact will close. This should signal to the system that the pump
is “In Use” or that the transaction has ended.
5.5.3.3 Authorization Output Wires
The dispenser requires an authorization signal from Islander Prime to start a sales transaction.
Without this authorization signal, the electric valve (or pump) will not open and the sales
transaction will not begin. Islander Prime switches the AC power signal to the valve. When the
dispenser receives the authorization signal, it enables the fuel flow.
5.5.3.4 MPI-C Pinouts
The following tables provide MPI-C pinout connection details, based on the Terminal Block
Map found on the power supply protective panel (see Table 11, Table 12, and Table 13). The
tables are laid out as follows:
• The pin number for each cell corresponds with the pin numbers displayed in the Terminal
Blo
ck Map found on the inner wall of the Islander Prime unit.
• Each block of cells shows the channels for that
configuration, as follows:
- (Green): Channel #1
- (Peach): Channel #2
-
(Purple): Channel #3
- (Beige): Channel #4
Each cell defines the signal that is sent over that pin in the terminal block port.
