TROUBLESHOOTING GUIDE
CAUTION: DURING TROUBLESHOOTING PROCEDURES MAKE SURE A SPARE SAFETY PULL
PIN IS INSTALLED IN THE EXTINGUISHER HANDLE. THE SPARE SAFETY PULL PIN MUST BE
REMOVED FROM THE HANDLE WHEN TROUBLESHOOTING IS COMPLETE.
Main CPU Board
(P/N G602)
Problem:
No Fire Detect Mode
Check the following: (See
FIGURE 3
)
•
The Main CPU has built in self-diagnostics, see
page 5, “Diagnostic Test”.
Release Solenoid Latch
Problem:
No Activation of Latch
Check the following: (See
FIGURE 3
)
•
The solenoid plug is connected to the correct
position on the main CPU and is fully mated.
•
Place a spare Pull pin in the Handle.
Use a
Multi-meter to measure the DC Voltage signal
across J9 (VALVE) connector on the board when
the system is manually activated by pulling the
pull station or placing a temporary short across
J3 (REMOTE PULL). If signal does not appear,
replace the CPU board. If signal exists, perform
next step.
•
Disconnect the solenoid valve plug from the main
CPU, use a Multi-meter to measure the
resistance between the two contacts in the plug
coming from the solenoid. The resistance should
be approximately 190 ohms. If there is no
indication of resistance, replace solenoid.
Electric Shutoffs
(P/N G319)
Verify the configuration and determine if the electric
shutoff is a 3 Prong, 4 Prong or Hardwired version.
Problem:
No Electrical Power To Stove using
Interconnect Cable Configuration
•
Review installation instruction on pages 8-12 and
make sure that the shut-off is properly installed.
Perform Reset Stove procedure on Page 12.
•
Verify that the Interconnect cable between the
Main CPU control board and shut-off is fully
plugged into to the correct connector on both
ends of the cable and that the connectors are
fully mated.
•
Press the reset button on the Main CPU and
verify the green indicator momentarily lights up.
•
Verify power is getting to stove by testing a
burner. If there is no power, disconnect the
electric shutoff and plug the stove directly into the
wall.
•
If power to the stove exists by plugging it directly
into the wall, replace the electric shutoff. If no
power exist to the stove, check site condition.
•
For hardwired versions, have a licensed
electrician verify that the source power is
supplied to the same side of the contactor as the
orange wires from the ESO printed circuit board.
Problem:
No Shutoff Activation using the
Interconnect Cable
•
Confirm that power is supplied to the stove
through the electric shutoff.
•
Press the “Reset” button on the main CPU and
make sure that the green indicator momentarily
illuminates. If green indicator does not illuminate
then run “Diagnostic Test” on pages 5-6 of this
manual.
•
Verify that the Interconnect cable between the
Main CPU control board and shut-off is plugged
into to the correct connector on both ends of the
cable and that the connectors are fully mated.
•
Perform “Arming the System” procedures on
Page 15. If power to the stove stays on after a
diagnostic test, and there are no Diagnostic Code
“beeps”, then perform the next step below.
•
Disconnect the interconnect cable from the
Electric shut off. Using a small piece of wire,
create a short across the two outside pins of the
white 4 pin socket on the shut-off.
Note- Do not
make contact with either of the two inner
pins
. Activation of the shut-off should occur. If
activation does NOT occur, replace the shutoff.
•
If activation occurs, reset the shutoff, reconnect
the interconnect cable and perform
Arming the
System
on page 15 again.
If power to the stove
stays on after a diagnostic test, and there are no
Diagnostic Code “beeps” then replace the Main
CPU board.
