When fuel is not being transferred, the pressure in the underground piping system of a gasoline station may fall due to thermal contraction of the fuel within the line. This condition may create problems during future dispensing operations. The ARM-4073 Automatic Repressure Module ensures line pressure by periodically starting the submersible pump (turbine) to repressurize the line.

An ARM Module contains two timer circuits which operate in sequence. The first determines the pump running time. The second determines the delay time - the amount of time between pump operations. The following statements outline the operations of the ARM Modules. With power applied, the module is active and performs its timing functions. The pump timer is the first to operate following the application of power. Following the completion of the pump cycle, the delay timer determines the elapsed time to the next pump cycle. There is a small switch module located in the center of the circuit board. This module contains five miniature switches which are used to program the timers. The timers operate asynchronously in relationship to dispensing authorization signals. That is, the timing sequence does not monitor dispensing operations and therefore the module may energize the pump contactor during dispensing operations. This will not create a conflict with dispensing. |
