Introduction to MC100-1 Control Module
The VP1000-5 is interfaced with the dispenser through the MC100-1 control module. The MC100-1 is directly wired to
the dispenser power and typically the solenoid valve signal and neutral wires located in the upper electronics area as
shown in Figure 1. This allows the Healy equipment to recognize when a dispenser is authorized to dispense product. The
MC100-1’s solenoid disconnect relay provides interruption of the solenoid valve neutral circuit when the VP1000-5 is in a
fault state. Figure 2 describes the meanings of the indicator lights on the MC100-1.

If the VP1000-5 vacuum pump encounters an issue during operation it will communicate a fault condition to the
MC100-1 which will visually display either a solid or flashing red light. This assists service personnel in the
troubleshooting of fault conditions.
