6.3.1 Mounting the Tank Gate Interface
Before mounting the Tank Gate Interface, make certain that any enclosure used can house the
Tank Gate Interface. Refer to the dimensional drawing below (all dimensions are in inches). The
recommended standard housing for the Tank Gate Interface is a NEMA TYPE 4 enclosure. This
enclosure is suitable for both indoor and outdoor applications.
6.3.2 Select the Unit Address
Switch SW1 sets the Tank Gate Interface’s one byte, binary
address (0-15). Switch SW1-1 is the most significant bit
(MSB) while switch SW1-4 is the least significant bit (LSB).
When a switch is in the ON or CLOSED position, the resulting
bit is a one.
