3.3.2.4 Submersible Relay Control
The submersible relay control output provides 120VAC [int’l - 240VAC] for controlling a
submersible starter relay. A relay is required to interface to the submersible pump. After the
display resets, the electronic register supplies power on this line to close the submersible
starter relay in order to activate the submersible pump. In multiple dispenser applications, all
dispensers operating the same submersible starter relay must be on the same phase of
power or must control the common starter relay through an isolation box.
The submersible pump control board uses solid state relays. Solid state relays have a “bleed
current” of up to 1.5mA for 120 VAC applications and 1.9mA for 240VAC applications. This
bleed current on the dispenser’s relay control signals may cause a logical device such as a
power interruption system to misinterpret the control signals as being “on” when they are not.
Consult the manufacturer of the control device on how to properly load their system to
prevent false-positive signals.
Failure to suppress the bleed current in applications where a false signal may be
detected can cause the submersible pump to run when it should not, and thereby may
result in equipment damage, a fuel spill, or personal injury.
3.3.2.5 Optional Pump Direct Drive Relay
An optional solid-state relay can be provided to directly drive pumps up to 1 HP, not to
exceed 14 Amps at 120 VAC or 7 Amps at 240 VAC. For use with transfer pumps where a
separate drive relay is not available or convenient. This relay turns on/off at the same time
as with the “Submersible Relay Control”. This relay controls only 1 leg to the pump.
3.3.2.6 Current Loop + & Current Loop –
Communications from the control device to the dispenser is accomplished through a 2-wire
current loop connection. The installation wiring diagrams in Appendix C show connections to
various control/connections devices for controlling the dispenser from a device capable of
communicating to the dispenser via the current loop.
NOTE: Data wires from the DFS Control System may be installed in the same conduit
containing the AC power wiring to the dispenser (NEC Class 1).
3.3.2.7 CAT + & CAT – (T7 option)
The CAT + and CAT – wires are used for interfacing the payment terminal to a Point of Sale
system using the DFS RS485 communication lines.
3.3.2.8 Ethernet Communication Cable (iX Fleet or T7 option)
An Ethernet Communication Cable is used for connecting to the optional iX Fleet or T7
control system. This wiring must never be in the same conduit or raceway as Class 1 wiring.
For full details on the interconnections, reference the iX Fleet or T7 Appendix in this manual.
These connections go directly to the control board or Ethernet interface board and are not
found on the terminal block.
3.3.3 Electrical Termination Descriptions – Pulse Output Interface Option
The chart to the right describes the
additional electrical inputs and
outputs associated with the pulse
output interface option and can
provide assistance in interpreting
the Pulse Output Interface Option
Wiring Diagram in Appendix C.
These connections are found on the
optional Pulse Output terminal block
located in the head of the dispenser.
