ELECTRIC SHUTOFF (P/N G319)

The electric stove is shut off during system activation by two methods. With the electric shutoff one of the following is used.  (1)- Using the interconnect cable (standard) from the Main CPU Control board terminal strip (P1-5 & 7) to the electric shutoff completes a hardwired signal which in turn activates the shutoff unit.  (2) When using the Sonic Receiver board (optional), the shutoff continuously monitors for a “sonic” alarm from the Main CPU board located in the system enclosure. The Sonic Receiver board responds to the audible signal and activates the shutoff.  Both methods cause all electrical power to the stove to shut off.
In the event that the electric shutoff is activated or an interruption in power occurs, it must be reset. See FIGURE 15.

INSTALLATION

NOTE: Insure electric stove shutoff is installed within the same room as the Main CPU control board (part #G302) for proper unit operation.

  1. Turn” OFF” electricity to the range
  2. Identify your electric plug configuration; 3-prong, 4-prong or hardwire. (See FIGURES 12A, 12B, and 12C).
  3. Remove the stove power cord from the wall outlet and plug it into the outlet on the stove shutoff unit (See FIGURE 15).
  4. Insert the stove shutoff power cord into the wall outlet.
  5. Plug the “Interconnect Cable” into the shutoff.
  6. Install Interconnect cable between electric shutoff and Main CPU.
  7. Connect the spade lugs to terminal strip P1-5 & 7 on Main CPU. (See FIGURE 3 & 14)
