Kraus Electronic Dispenser
In addition to the general diagnostic procedures that should be employed when troubleshooting a
fuel system, there are some unique considerations when working with Kraus dispensers.
TTC and TTP Wiring. Make sure the TTC and TTP wires coming from the Kraus head are not
reversed.
Wiring for Manual Operation. The Kraus head has a wire (#14) that is used to put the Kraus head
in manual operation. This wire should not be tied to 110vac (hot), but should be capped off and
unused.
Kraus Software Level. The software in the Kraus head needs to be of a certain level or above to work
correctly with PIE controllers. Below are the Kraus models with their appropriate software levels:
Micon 100 w/ 152 board ver 3.1
Micon 100 w/ 252 board ver 6.30
Micon 100 w/ 463 board ver 7.03
Micon 200 ver 1.09
Micon 300 ver 2.04
Micon 500 ver 1.33AN
Dispenser IDs. Dispenser IDs are not set in a Kraus dispenser head. The dispenser ID is derived
from the position the dispenser is wired into on the PIE configurator board.
Diagnostic LEDs. The PIE configurator (Kraus) has LEDs to help diagnose communications problems.
There are transmit (Txd), receive (Rxd) and control (Ctrl) LEDs on the PIE configurator board that
indicate if the PCXZ controller is transmitting to the Kraus head or if the Kraus head is trying to talk to
the PCXZ.
Bennett Electronic Dispenser
In addition to the general diagnostic procedures that should be employed when troubleshooting a
fuel system, there are some unique considerations when working with Bennett dispensers.
Settings. Make sure the enable switches on the PIE Bennett configurator board are set correctly for
the dispensers that exist. If switches are turned on for dispensers that don’t exist, communications to
the other dispensers will not work.
Polarity. Observe the polarity of the communication wires from the Bennett dispenser. If these wires
are reversed, dispenser communication will not work at all.
Dispenser IDs. Dispenser IDs are not set in a Bennett dispenser. The dispenser ID is derived from
the position the dispenser is wired into on the PIE configurator board.
Diagnostic LEDs. The PIE configurator (Bennett) has LEDs to help diagnose communications
problems. There are transmit (Txd), receive (Rxd) and control (Ctrl) LEDs on the PIE configurator
board that indicate if the PCXZ controller is transmitting to the Bennett head or if the Bennett head is
trying to talk to the PCXZ.
