Mechanical PCU Option System Overview
Pulse Rate Parameter
Set the pulse rate parameter with the appropriate pulse rate for your pump. The mechanical
interface supports pulse rates of 1, 10, 100, 500, and 1000 in gallons; 1, 10, 100, and 250 in
liters. If using a 9800 as a mechanical pump, pulsing should be set to 1000:1 for gallons; 250:1
for liters. If using bulk fueling, the pulse rates for gallons will be 1:1, 10:1 and 100:1 for
gallons and those listed above for liters.
Transaction Changes
If you have the mechanical interface option, the transaction quantity decimal places are
truncated to match the pulse rate (that is 10:1 pulse rate would display xxxxx.x; 100:1 pulse
rate would display xxxxx.xx, and so on).
Mechanical PCU Option
The Mechanical Pump Control Unit (Mechanical PCU) option for the TopKAT 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 with Mechanical PCU is mounted on top
of a pedestal. All PCUs can be mounted within the pedestal or wall-mounted. All pump/
dispenser wiring connections are made within the TopKAT pedestal, when using internal
PCUs or within the wall-mounted PCUs. The TopKAT with the Mechanical PCU option can
also be used in a master/satellite configuration. Use of this interface results in additional
hardware and software parameters.
Hardware
Each mechanical PCU includes two solid-state relays and one manual override switch per hose
outlet which control power to the fuel dispensing equipment. The TopKAT can handle
quantity pulsing rates as listed below in the Pulse Rate Parameter section. Wiring connections
and switch settings for the Pump Control PCB are discussed in more detail in the Installation
Manual.
Software
When used with the Mechanical PCU option in standalone mode or master/satellite (one
TopKAT controlling up to eight hoses on two mechanical PCUs), two parameters in the Pump
File are used: pump switch timer and pulse rate. The parameters are loaded via the keypad
under LOAD PUMP TABLE in the Pump file or through the terminal using the L PU (LOAD
PUMP) command.
Pump Switch Timer Parameter
The pump switch timer parameter prevents new fueling transactions at a pump when the
handle has been left on from a previous transaction. In this case, when a new transaction is
initiated, the pump cannot reset and, if pumping is allowed, the quantity shown at the pump
includes the previous transaction quantity.
