NMEA2000®
Check that the unit is connected to the
NMEA2000®
network
securely and that the network is powered correctly.
PLC:
Check that the three connections to the connecting block are correctly and
securely fastened. Check that there is a 12 or 24 power feed connected.
NMEA2000®
There is no tank data on the network that matches the 5250 tank
type and device instance switch position.
Troubleshooting Procedure
Symptom
“NO INPUT” displayed
No display
Level does not reach 0%
in analogue mode
Ensure that the signal voltage reaches 0v for the sense input.
Do not attempt to
use an external pull-down resistor
, as this will affect the internal calibration
circuitry of the device.

SAFETY INSTRUCTIONS
This unit should only be installed by a person competent and experienced in working on electrical systems on
boats. Before beginning the work the battery should be disconnected to avoid the risk of a short circuit, fire or
explosion. Before drilling any holes to mount the unit or run the cabling always make sure it is safe to do so.
INCLUDED IN THE BOX
• 5250 Deck Gauge
•Instalation and Operation Instructions (this document)
•3x M4 30mm countersunk screws
•3 x M4 nuts
•3 x M4 flat washers
LOCATION AND INSTALLATION
The 5250 Deck Gauge should be mounted horizontally or vertically near the tank filler cap, so that it can be seen
easily during the tank filling operation. Supplied in the box is a full size mounting template showing the external
dimensions, the mounting hole sizes and their positions to simplify mounting. The three mounting holes in the bezel
are designed to fit suitable M4 countersunk or self-tapping screws.
To connect to the NMEA2000® network use a NMEA2000® drop cable to connect from the male M12 plug on the rear
of the unit to the nearest Tee connector.
To connect to a voltage feed from a PLC system or similar connect a three core cable from the connector block on
the rear of the unit to the voltage source as follows:
(Illustration of the rear of the unit showing three core cable connected to the connecting block to ground, +12/24
Volts and signal from 0-10 Volts)
Please note that the unit must be connected to
EITHER
the NMEA2000® network OR the PLC source.
DO NOT
CONNECT
the unit to both sources at the same time.
CALIBRATION AND SETUP
No calibration is required. Simply set the small rotary switch to the tank instance of the tank to be monitored in
the table below or set to ‘F’ if the unit is to be used with a PLC input and it will automatically display the tank
level percentage.
