Printing Reports
Each day at midnight an automatic printout of the previous
days’ activity will be printed. This will show all the previous
data about run time and will show if any errors occurred
that day. It does not show a history of errors.
To get a history printout, press both RESET buttons on the
front panel at the same time to print a 15-line summary of
the last 15 failures. If there are more than 15, the oldest
line is dropped off and the latest line is added.
Pressing the PRINT button will get an up-to-the-minute
printout of the site summary and current activity. All
printouts should be saved for local authorities.
The 6280 has a replaceable printer ribbon cartridge and
uses standard non-thermal paper. The replacement part
numbers for the paper and the ribbon are:
628028 Printer paper roll
628029 Printer ribbon cartridge
Refer to the section “Changing Paper / Ribbon Cartridge
Guide”.
System Monitor Control Box (SMCB)
The SMBC serves as a junction box for the CB1
relay / CB1A relay socket and the 1005W-4 solid-state
relay. It also acts as a junction box for the wiring cable
supplied from the 6280 System Monitor, the 12VDC plug-
in power supply, eld wiring from the 9800-1 Pressure
Switch, eld wiring from the 6275 Vent Sensor Assembly,
and eld wiring from the gasoline pump motor relays.
Mounting the SMBC
Mount the SMCB near the gasoline pump motor relays and
near a 110V standard electrical outlet for the 12VDC plug-
in power supply.
It should also be near the electrical conduits from the
9800-1 Pressure Switch and the 6275 Vent Sensor
Assembly. Mount the box rmly using screws (not
supplied) through the holes in the bottom of the box.
The CB1 Relay, mounted in the CB1A relay socket, is
connected to the power of the vacuum source and closes
a contact that activates the yellow MOTOR LED light and
usually the red LOW LED, on the 6280 System Monitor.
The RUN light will illuminate and the LOW light goes dark
when the monitor receives the signal from the 9800-1
Pressure Switch, that the proper vacuum level has been
reached within the predetermined time.
With an input signal from a gasoline pump motor relay, the
1005W-4 Solid State Relay senses the activation of any
product pump and transfers that signal to the starting relay
of whichever vacuum source is being utilized at the site.
Note: Keep high-voltage wiring and low-voltage wiring in
separated conduit.
