147193 Installation Manual DEF 100-200
Rules to ensure proper operation:
Each dispenser uses one 115V or 230V circuit for dispenser power. Put no more than two (2) dispensers on a
1.
circuit breaker.
2.
Do not connect any other devices or motors to these circuits.
3.
Put the pump wiring in a dedicated separate conduit. Do not put non-pump related wires, such as price signs
or intercoms, in the same conduit as pump wiring.
4.
Use only 14-gauge stranded gas and oil resistant THHN wire.
5.
Do not use wire nuts anywhere in the pump wiring runs.
WARNING: All Dispenser AC Power circuits (For Remotes Systems Only) must be on the same phase
or damage will result to the dispenser power board or the sub-pump relay box.
CONNECTING PUMP MOTO R POWER FOR REMOTE D ISPENSERS
Remote dispensers require the use of submerged pumps. These pumps are located in the Underground Storage
Tank and are controlled by a "control relay". The dispenser sends the signal to the control relay to energize the
submerged pump. Consult with the submerged pump manufacturer for more information on control relay boxes.
Connect the "Motor Out" power wire between the dispenser and the control relay box as follows:
Submerged Pump Motor Control — Connect to terminal 2 of TS2 located on the CPU electronics enclosure.
This should be a 14 ga. wire. It is recommended that the installer use a blue wire for submerged pump motor
control. Refer to the Remote Power Wiring Diagram section of this manual.
Note - Select Submerged Pump control or Suction Pump control by setting a jumper wire on the CPU. Make sure
that there is a jumper from P1 to P3 on the CPU if controlling a submerged pump relay. This will be set at the
factory.
CONNECTING PUMP MOTO R POWER FOR SUCTION SYSTEMS
Self-contained dispensers have the pump motor mounted in the lower hydraulic area. The power is passed to the
pump motor using the pump motor relay located on the CPU board in the electronic enclosure.
***Suction motor connections are pre-wired to the terminal block from the factory. Please refer to
the Self Contained Power Wiring Section of this manual.
Note - Select Submerged Pump control or Suction Pump control by setting a jumper wire on the CPU. Make sure
that there is NO jumper from P1 to P2 on the CPU board if controlling a suction pump motor. This will be set at the
factory.
CONNECTING THE COMMU NICATION WIRES
For the RS-485 communication wires, use 18 gauge, twisted wires at 8 twists per foot. Refer to the RS-485 Wiring
Diagram in the wiring section of this manual. Connect the RS485 communication wires to TS1 on the CPU
personality module as follows:
TS1 - 1 RS485 Positive (+) Orange 18 ga.
TS1 - 3 RS485 Negative (-) Brown 18 ga.
