Sequence of operation:

 

    1. Setup

                                                              i.      The key switch is turned on. The green light will come on.

                                                            ii.      The wind speed setpoint is set through the touch screen.

                                                          iii.      The time clock is set through the touch screen.

 

    1. Automatic operation

                                                              i.      The time clock starts the system.

                                                            ii.      If the day/night sensor indicates darkness, the anemometer reads an appropriate wind speed and the emergency stop switches are set, the MCP will send power to the system.

                                                          iii.      For systems with supervisory stations: The supervisory station valves will open.  The MCP will supervise the pressure switches on the supervisory station.  If either switch goes into alarm, the MCP will shut down the system.

                                                           iv.      The MCP sends power to the transformers on the individual appliances.  This in turn powers up the individual listed safety controls on each appliance.  Each safety control monitors the flame for the appliance and takes appropriate action as necessary.

 

    1. Manual operation

                                                              i.      Punch in the password for Manual mode.

                                                            ii.      Set the individual effects to “on” using the touch screen,

                                                          iii.      Press the start switch to turn them on immediately.

NOTE: The Manual mode bypasses the wind sensor, time clock, day/night sensor and emergency stop switches.  As such, it should only be used under direct supervision of trained personnel and only for testing and adjustment.
