Page 7: Pre-Installation Check
PRE-INSTALLATION CHECK The MICON 500C is an electronic pumphead designed for use with compressed natural gas (CNG) dispensers. After carefully unpacking the MICON 500C, inspect for shipping damage. Refer to the options label(s) on the MICON 500C shipping box(es) to ensure the MICON 500C is properly configured for the intended application. - Page 8 PRE-INSTALLATION CHECK (CONT’D) 3. The MICON 500C digital display can be manually triggered to display configuration event counters data in the dollar and volume displays, followed by the software version number in the price display. To do this: Ø Flip the handle switch rapidly ON, then OFF. The display will show the configuration event counters in the dollar and volume displays, and the software version in the price display.
- Page 9 PRE-INSTALLATION CHECK (CONT’D) 4. Figure 3 (preceding page) indicates both counters (dollar and volume) are set to 0001. To check the current configuration of your MICON 500C, use the INFO-PAC receive functions, described in the INFO-PAC m500C Programming Manual, and outlined in steps a) to d) below: The RX MICON (m500) setting on the INFO-PAC is designed to receive MICON 500C settings from units which have already been programmed.

Page 11: Handle Switch Coupling
HANDLE SWITCH COUPLING 1. The handle switch coupling on the side of the MICON 500C must be connected to the dispenser handle. In most installations, the dispenser handle can be coupled directly to the MICON 500C. The MICON 500C handle switch can be turned to the ON position by rotating the actuator shaft 90 degrees in either a clockwise or counterclockwise direction. - Page 12 HANDLE SWITCH COUPLING (CONT’D) 2. If desired, a normally open handle switch can be connected to the intrinsically safe 2 pin plug. In this case, the actuating shaft need not be connected and should be left in the Handle OFF position. FIGURE 7 Handle OFF INTRINSICALLY...

Page 13: Handle Shaft Actuation
HANDLE SHAFT ACTUATION As outlined in explanation accompanying Figure 6, page 6, the MICON 500C handle switch may be switched ON by rotating the actuator shaft 90 degrees in either direction. As shipped from the factory, a clockwise rotation of the coupler assembly (as viewed from the coupler side) is required to switch the pumphead ON. - Page 14 HANDLE SHAFT ACTUATION (CONT’D) FIGURE 10 HANDLE SHAFT ACTUATION FOR CLOCKWISE ROTATION Remove cotter pin from coupler assembly after turning the assembly to the desired OFF position. Rotate actuating shaft until flat side of actuator shaft faces UP when handle OFF, then re-install cotter pin.

Page 21: Post Installation Check
POST INSTALLATION CHECK After completing the installation of the MICON and checking all wiring connections, correct operation should be verified as follows: 1. Enter a price, as described below (also described in section 6.2.2 – Setting Prices, page 19). Go to breaker box and turn OFF AC power to MICON 500C electronic pumphead being serviced. Caution: Ensure breaker box does not feed power to equipment which should remain ON. -
Page 22: Micon 500C Operation
POST INSTALLATION CHECK (CONT’D) 5. For stand alone operation, turn ON the dispenser handle. The authorization in this case is bypassed and the main board receives a direct signal. The display resets and the main flow valve is signaled by the MICON to open and commence fuel flow. 6. -
Page 23: Micon 500C Communicator Operation
MICON 500C COMMUNICATOR OPERATION The hand held communicator (part # MC 200D, available as an option) allows the reading of dollar and volume totals and price setting, as described below. The communicator can also be used as a troubleshooting tool to obtain current readings of product flow rate, temperature and pressure (see section 6.2.3, page 20). -

Page 39: Software
SOFTWARE This system employs algorithms based on ideal gas law equations to predict an end-of-fill final pressure. Variables such as the dynamic gas pressure, ambient temperature and gas temperature are utilized. The system basically functions as follows: When each fill is authorized, the main flow and high bank valves are opened, recording the dispensed amounts. -
Page 40: End-Of-Fill Determinants
END-OF-FILL DETERMINANTS Following is a list of conditions which can terminate a fill (i.e., reset the register): 1. The pressure at the dispenser transducer has reached the predicted final fill pressure, and the fill terminates under normal operating conditions. The fill is terminated once the restart timeout times out. -
Page 41: Excess Flow / Excess Fill
RESTART TIMEOUT AND NOISE BLANKING (CONT’D) The restart timeout and noise blanking work together to stop and restart the fill as many times as necessary to ensure that the end-of-fill is at an accurate pressure before the fill is completely terminated. -
Page 42: Optional Parameters
EXCESS FLOW / EXCESS FILL (CONT’D) Reset Method 2: This option terminates the fill on an excess flow shutdown. The MRST (manual reset switch) input requires resetting before the system returns to "normal" operational state. EXCESS FILL (OR EXCESS RESET): The Excess Fill feature is an additional safety shutdown with limited applications. -
