s
Corrective Action
No Communication between FHO and SO Controller
No connection to
the station from
FHO Stations
screen.
Cabling issue
Inspect the network
cable to LAN2.
1
Verify that the LAN2 Port LED is
blinking.
2
Unplug the cable and plug it
back in.
3
Replace the LAN cable (if
necessary).
4
If the cable is in a good condition;
contact the IT department to
confirm that the switch/router
connected to the LAN cable is
installed properly.
5
Check the controller network
settings (IP addresses, mask,
gateway, etc.).
No Communication with the Pumps (LAN to 3x 485 CommVerter)
Warning signs
displayed for all
pumps on the
SiteOmat Status
screen.
Incorrect LAN to 3x 485
CommVerter setup.
• Check the physical
connection of the
LAN to 3x 485.
• CommVerter to the
local network
(5- port switch
activity).
• Check network
connectivity by
performing a “ping”
command locally or
remotely, through
PuTTY application.
1
If there is no activity on the LAN
port connected to the LAN to 3x
485 CommVerter, replace the
short Ethernet cable and /or
change the LAN port to confirm
normal operation.
2
Check the status of the LEDs on
the LAN to 3x 485 CommVerter
(upper right corner of the board):
the first and the third LED should
be lit to confirm power and
network connection, while second
LED should blink to confirm
network activity. The last two
LEDs (from left to right) should be
blinking constantly, to confirm
communication with controller.
3
In cases where all LEDs are lit
periodically (every 30 seconds)
the unit is resetting due to
connection loss to the controller.
4
Reset the IP and reconfigure the
Pump Server (PS) in controller
setup.
No Communication with the Nozzles
Can’t read the
vehicles and/or no
authorization at
the pumps.
No communication with
the FHO.
Incorrect nozzle reader
setup.
• Check the software
license is correct.
• Check the
programming of the
WNRs.
1
Re-enter the software license.
2
If no activity on the LAN port,
check the cable and/or change
the port on the 5-port switch.
