Field Replacement /Addition of Sensor Scaling and Special Function Cards

When servicing the AquaPro in the field, cards can be removed or inserted. When doing so, it is recommended
that power should be off to the AquaPro.
Cards should never be removed just to connect wires to the terminal blocks. Terminal block wiring should be
done with the cards installed.
To remove an existing card or blank from a slot, depress the card tab located in the interior wall of the base
enclosure with a small flat blade screwdriver and pull up on the wiring tab on the top of the card. The card will
slide out easily.
When all four cards and card blanks are removed from the AquaPro, the backplane and card guides are visible.
To install any Card:
1. Install sensor scaling cards from left to right without leaving any gaps. The first card goes in Slot 1 (far left);
second scaling card goes in Slot 2, and so on.
2. Relay and communications cards are always inserted into Slot 4.
3. Orient the card so that the locking tab for the card is lined up with the interior wall of the AquaPro.
4. Line up the edges of the card so that they slide into the Slot card guide.

If there is an empty card slot in the AquaPro unit, the cards in a
higher number slot would not be read, nor be viewable, on the main
display.
