4. Quick Stop Button as Auxiliary Emergency Stop Switch. The Quick Stop Button has two
terminals to receive wire connections. It removes power by depressing the red mushroom-shaped
button. Power is restored by turning the button clockwise a partial turn until it pops back out to the
reset position.
Check local requirements for an Emergency Stop Switch. Most regulations require an Emergency
Stop Switch to be remotely located at least 20 feet from the fuel island.
CAUTION
• If wired as a service island emergency stop switch for all service island equipment, the Quick
Stop Button must be used only to control a contact starter controlling power to the service
island. Under no circumstances will power wires for other service island equipment be brought
into the FMU for control by the Quick Stop Button.
• To be in compliance with the requirements for a service island emergency stop switch, all power
to the service island must be removed when the emergency stop switch is activated. This must
also include the 110 VAC carried to the Quick Stop Button.
ATTENTION
• Si le bouton d'arrêt rapide (Quick Stop Button) est câblé comme commutateur d'arrêt d'urgence
d'îlot de service pour tout l'équipement d'îlot de service, le bouton d'arrêt rapide doit être utilisée
seulement pour côntroller un interrupteur de secours côntrollant le courant pour l'îlot de service.
Dans aucunes circonstances doit-on introduir des câbles pour des autres îlots de service dans le
FMU pour être controllé par le bouton d'arrêt rapide.
• Pour être conformément aux conditions pour un commutateur d'arrêt d'urgence d'îlots de service,
tout courant à l'îlot de service doit être coupé quand le commutateur d'arrêt d'urgence est
actionné. Ceci doit également incluir les 110 V de courant alternatif fournis au bouton d'arrêt
rapide.
a. Check that power is removed from the emergency stop switch contact starter and all service
island equipment.
b. Route two 12 AWG THHN wires through approved conduit from the emergency stop switch
contact starter to the FMU: one for incoming power to the contact starter, and another for
switched power from the Quick Stop Button back to the contact starter.
c. Connect one 12 AWG wire to one contact of the Quick Stop Button.
d. Connect the other 12 AWG wire to the other contact of the Quick Stop Button.
e. Restore power to the contact starter and all service island equipment.
5. On-Site/Transaction Printer (see Figure 4-6 for Pedestal I/O Board connections). Transaction
printers are connected to the FMU via a serial connection with an RS-232 cable. Cable length may
be extended to 4000 feet using RS-422 and short haul modems. See Product Bulletin 126 for use of
the Patton Electronics RS-232/422 converter in this application. Transaction printers may also be
connected to the FMU via a wireless connection. See Product Bulletin 133 for use of the Zlinx Radio
Modems for wireless transmission of RS-232.
Transaction printers must have a serial connection capable of being set to 4800 baud, 8 data bits, no
parity, and 1 stop bit. Serial connections are sometimes optional when purchasing printers. Ensure
the printer being purchased has a serial connection.
If the transaction printer is purchased from Syn-Tech Systems, Inc, it is preconfigured to the correct
communications parameters, and a surge protector and interfacing cable are provided. The surge
protector (part number 201421) and interfacing cable (part number 201669) may be purchased
separately by addressing the applicable part number.
Transaction printer connections are made to J3 EXTERNAL on the Pedestal I/O Board. See below
for the relationships between the connection points. If a connection is being made directly to the
printer, use the connection points listed under “Printer DB25 Pin”. If a connection is being made to
the optional 201669 printer cable, use the connections shown under “201669 Cable Color”.
