CHAPTER 5 - SENDER PROGRAMMING
To program the 710ES or 710SS 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" tab has been removed and it should be a black
tank sender, or if the "BLK" tab has been removed and it
should be a grey tank sender, then cut out the recessed grey-
black correction tab that says "GBC" next to it. This reverses
the effect of the grey and black tabs.
7. If either the "GRY" or "BLK" tabs have been removed and it
should be for a fresh tank, then remove the other "GRY" or
"BLK" tab. When both the "GRY" and "BLK" tabs are removed,
it is equivalent to neither of them being removed.
8. If the sender is single, no further programming is required.
9. If double stacked senders are used, the top sender must have
additional programming, as described below.
10. Refer to the 710ES and 710SS sender programming diagram.
To program the 710ES or 710SS sender as top or bottom:
1. Since the senders are all connected in parallel to save wiring
and to simplify installation, the senders must be programmed
so they know whether they are a single, top, or bottom sender.
This is done with the tab at the top center of the sender. See
the following diagram.
