G310A -A Page 20 Revised February 20, 2007 TROUBLESHOOTING GUIDE CAUTION: DURING CHECK OUT PROCEDURES MAKE SURE SAFETY PULL PIN IS INSTALLED. Main CPU Board (P/N G302) • Verify that the Interconnect cable wires to Main CPU control board are attached correctly on P1 Problem: Continuous Alarm terminal strip 5 (com) and 7 (N /O). Check the following: (See FIGURE 3) • Verify power is getting to stove by turning on burner. If, no power, disconnect electric shutoff • During test procedures, Push K1 on Main CPU to and plug stove directly into the wall. disable the alarm. • If power to the stove exists by plugging directly • Verify terminals are tight on P1 terminal strip. into the wall, replace electric shutoff. If no power exist to the stove, check site condition. • Sensor cable wires are not shorted or frayed. • For hardwired versions, have a certified • Open or bad connection to solenoid release electrician verify that the source power is valve. supplied to the same side of the contactor as the orange wires from the ESO printed circuit board. • Bad sensor - replace one sensor at a time. Problem: No Shutoff Activation using the Interconnect Cable Release Solenoid Latch • Perform Electric Shutoff Checkout procedures on Page 16 that are applicable to right configuration. Problem: No Activation of Latch • Confirm that power is supplied to the stove Check the following: (See FIGURE 3) through the electric shutoff. • Terminals are tight on Main CPU P1 -8 & 9. • Verify that the connector on the "interconnect cable" is plugged into the electric shutoff and that • Verify the red wire goes to P1 -8 and the black the other end of the interconnect cable is connect wire goes to P1 -9. to P1 -5 & 7 on the Main CPU board. • Use a Multi -meter to measure the DC Voltage • Short across the interconnect cable terminated signal on P1 -8 ( +) and P1 -9 ( -) during system on P1 -5 & 7 of the Main CPU board with a wire to checkout. If signal does not appear, replace complete the circuit in shut off. Activation should CPU board. If signal exists, perform next step. occur. If activation does NOT occur, replace the shutoff. • Disconnect wires from P1 -8 & P1 -9. Use a 9 -volt battery and place the red wire on positive and the • If activation occurs, reset the shutoff and perform black wire on negative. If solenoid DOES NOT INTERCONNECT CABLE TEST PROCEDURES ACTIVATE use a Multi -meter to measure the on Page 16 &17. Be sure to keep short across resistance between the two wires. The resistance sensor for approximately 20 -30 seconds to should be approximately 190 ohms. If no enable "Fire Detect Mode ". If activation does indication of resistance, replace solenoid. NOT occur at this point, replace the Main CPU board. Electric Shutoffs (P/N G319) Problem: No Shutoff Activation using the Verify the configuration and determine if the electric Sonic Receiver Assembly shutoff is 1- Sonic or 2- Non -sonic and whether it is a 3 Prong, 4 Prong or Hardwired version. • Perform "Sonic Receiver Test Procedures" Checkout on Page 16. Problem: No Electrical Power To Stove using Interconnect Cable Configuration • Check that "Sonic Receiver Assembly" is plugged into shutoff. Power ON light will be lit. • Perform Electric Shutoff Checkout procedures on Page 16 that are applicable to right configuration.
