2. The senders default to single or bottom operation if the
programming is not altered. Consequently, if the sender is
for single or bottom operation, nothing further needs to be
done to it (beyond programming it for the correct tank).
3. For a top sender, remove the tab that says "TOP" next to it.
4. This is all that is required to program the senders for single,
top, or bottom use. However, if you make an error, you have
one chance to correct it, as described below.
5. If the "TOP" tab has been removed and it should be a single
or bottom sender, then cut out the recessed top correction
tab that says "TC" next to it. This reverses the effect of the
top tab.
6. Verify that both the top and bottom senders have been
programmed for the correct tank.
To program the 710JS sender for the correct tank:
1. Since the senders are all connected in parallel to save wiring
and to simplify installation, the senders must be programmed
so they know which tank they are on. The senders can be
programmed for either the fresh, grey, or black tank. This is
done with the two tabs on the top corners of the sender. See
the following diagram.
2. The senders default to fresh tank operation if the programming
is not altered. Consequently, if the sender is for the fresh tank,
nothing further needs to be done to it.
3. If the sender is for the grey tank, remove the tab that says
"GRY" next to it.
4. If the sender is for the black tank, remove the tab that says
"BLK" next to it.
5. This is all that is required to program the senders for the
correct tank. However, if you make an error, you have one
chance to correct it, as described below.
6. If the "GRY" or "BLK" tab has been removed by mistake, the
sender can be changed to a fresh tank sender by cutting the
other corner tab ("BLK" or "GRY").
7. Refer to the 710JS sender programming diagram.
