TEST PROCEDURES - MARKET FORGE #08-6407 (120V) (CALIF.)
The following is a troubleshooting guide designed to find out if the Dual Function and Series 26 Controls are working
properly. It is not designed to find out why the controls have failed.
The Series Dual Function control is two controls in one, one half being the feed water control, the other half the low level
cutoff portion. The Series 26 is strictly a secondary low level cutoff.
Tools Needed: A digital or analog V-O-M (volt-Ohm-milliamp meter) a nd a set of test jumpers (alligator type).
1)
Turn off power to the control package.
2)
Remove the wires #100, #101, #102 from the probe connections "H", "LLCO" and "G" on the dual function and
"LLCO/130" and "G" on the Series 26.
3)
Remove the wires from the contact connections "COM", #104, and "N.O" from both relays on the dual function and the
relay on the Series 26.
CAUTION:
The Internal Jumper from "L1" & "COM" will be hot when power is reapplied.
Temporarily tape free end.
TESTING THE DUAL FUNCTION:
6)
When power is turned on, the LED on the side away from the transformer should light and the relay next to the LED
should be energized. Checking with the Ohm meter, the normally open contact should be closed and the normally closed
contact should be open. Bringing power to the control should not change the side of the control that contains the
transformer.
7)
Place a test jumper wire from either "G" terminal to the "H" terminal After a 10 second (+/-2) time delay, the LED will go
out and the relay next to this LED should deenergize returning the contacts to their original state. (Normally open should
be open, Normally closed should be closed)
8)
Removing the jumper from "G" and "H" should relight the LED and energize the relay.
9)
Place a test jumper wire from either "G" terminal to the "LLCO" terminal. The LED next to the transformer should light and
the relay next to the transformer should energize. Checking with the Ohm meter, the normally open contact should be
closed and the normally closed contact should be open.
10)
Remove the test jumper from "G" and "LLCO". The LED should remain lit for about 3 seconds (+/-) before going out. The
relay should deenergize at this time. The contacts should return to their original state.
TESTING THE SERIES 26:
11)
With power still applied to control package, place a test jumper wire from "G" terminal to the "LLCO" terminal. The LED
should light and the relay should energize. Checking with the Ohm meter, the normally open contact should be closed
and the normally closed contact should be open.
12)
Remove the test jumper from "G" and "LLCO". The LED should remain lit for about 3 seconds (+/-) before going out. The
relay should deenergize at this time. The contacts should return to their original state.
13)
If the above test shows that the control is operating properly, check all probe and solenoid wiring and the condition of the
electrodes (clean insulator) in the steam chamber. Check the conductivity of the liquid to make sure it is below 4.7L
ohms/cm.
14)
If after replacing all wiring, the system still does not operate properly, contact the factory.
