8 – Mechanical PCU Option
Description
The Mechanical PCU option for the TopKAT system allows the unit to control fueling and
gather information from up to eight mechanical hose outlets (Four per PCU, with a maximum
of two PCUs). The TopKAT system with Mechanical PCU configuration is mounted on top of
a pedestal. PCUs can be mounted within the pedestal or wall-mounted.
• PCUs mounted within the pedestal require a large square pedestal. When using pedestal-
mounted PCUs, all pump/dispenser wiring connections are made within the TopKAT
system pedestal.
• Wall-mounted PCUs use a triangular pedestal. When using wall-mounted PCUs, all pump/
dispenser wiring connections are made within the wall-mounted PCUs.
The TopKAT system with the Mechanical PCU option can also be used in a master/satellite
configuration.
The mechanical PCU includes two solid-state relays and one manual override switch for each
hose outlet, which control power to the fuel dispensing equipment (for the override switches to
place the pump in MANUAL position, individual PCU power must be present). The TopKAT
system can handle quantity pulsing rates of 1, 10, 100, 500, and 1000 per gallon measurement
and 1, 10, 100 and 250 per liter measurement.
