3. To check the diagnostics, press and hold the button for the
tank to be checked, the display will show the level for that
tank.
4. While continuing to hold down the button for the tank, press
the BATT button. When the display shows "dIA", release the
buttons, the display will then change to showing the signal
power diagnostic. This is indicated by a "P" showing on the
left digit, for example "P26" indicates a 26% signal power.
5. The signal power will show for 5 seconds. The display will
then change to showing the sender height. This is indicated
by a small "h" showing on the left digit, for example "h 6"
indicates that the sender has 6 receive segments, which is 9
inches high for an ES sender.
6. After 5 seconds of showing the height, the display will shut
off.
What to do if the system freezes or is unresponsive:
1. If the display is unresponsive, it may be "hung" due to a static
discharge or electrical noise. Try rebooting it by shutting off
the 12V power to it for a few seconds, then turning it back on.
What to do if operation becomes erratic or stops completely:
2. Make sure all wiring connections are solid. Do not use spade
connectors to join wiring as they will degrade over time. Use
insulated crimp-on butt connectors or solder and insulate the
wire connections.
What to do in two console systems if the two displays do not
read the same:
For dual display console applications, if the consoles disagree the
most likely reason is a bad console ground. Both console grounds,
and the sender grounds, must be connected together with ground
wiring. Do not depend on metal chassis components. See item 8
in the following section for further details.
