5 – Mechanical Interface Option
Description
The Mechanical Interface option for the TopKAT allows the unit to control fueling and gather
information from up to two mechanical hose outlets (two singles or one twin). The TopKAT
with mechanical interface is mounted on top of a 50-inch high pedestal. All mechanical
interface components are mounted within the head of the TopKAT and all wiring connections
are made within the TopKAT; no electronics or control devices are present in the pedestal. The
TopKAT with mechanical interface can also be used in a master/satellite configuration.
The mechanical interface includes two solid-state relays and one manual override switch per
hose outlet which control power to the fuel dispensing equipment. (Power must be present on
the TopKAT in order for the override switches to place the pump in MANUAL.) The TopKAT
can handle quantity pulsing rates of 1, 10, 100, 500, and 1000 per gallon measurement and 1,
10, 100 and 250 per liter measurement.
