GASBOY Electric Keytrol
6-2 03/28/03
The finish on GASBOY Electric Keytrol is a high-heat baked synthetic enamel, similar to that used
on automobiles. The life of this finish can be lengthened several years if, at regular intervals, the
painted surfaces are thoroughly cleaned with a high grade automobile polish and then protected
with a coat of paste wax. Do not use abrasive cleaners or polish. Do not use high pressure
spraying equipment.
In order to retain the unmarked finish on stainless steel, occasional cleaning is required. In
corrosive atmospheres, such as coastal areas, a more frequent cleaning schedule is necessary.
Under ordinary conditions, washing with detergent or soap and water, followed by a clean water
rinse, is sufficient. If hard water is used, the surface should be wiped dry with a soft clean cloth to
prevent the formation of water spots. Marks or spots, such as grease, oily fingerprints and
smudges which resist soap and detergents, will have to be removed with a stronger cleaner. (DO
NOT use ordinary steel wool as iron particles may adhere to the surface and cause corrosion.)
Care should be taken in choosing a cleaner because any cleaning compounds or powders which
contain abrasives can scratch a mill-rolled finish. Care must be exercised in their use to run in the
direction of the polishing lines in the steel, never across them. After cleaning, an application of
paste wax is recommended to protect the surface and prolong the interval between cleaning.
TROUBLESHOOTING
The paragraphs that follow detail troubleshooting procedures for major components in your
Electric Keytrol.
ANTI-FALSE COUNT RELAY, P/N 0M0017
1.
To check for faulty relay, remove relay and short pin 6 to 7. Operate dispenser. If counter
operates, the time delay relay is faulty. Replace with a new unit.
2.
The dispenser and Electric Keytrol can be operated indefinitely this way, only the unit may
pick up a count (0.1 gallon) on start-up if the pulser has stopped in a closed position.
POWER RELAY, P/N 0M0015
1.
Check power relay for movement of the armature when a key is inserted and turned.
2.
If the armature moves in, but the pump will not run, move bypass switch to MANUAL. If the
pump starts, the trouble is in the power relay contacts. Replace power relay or clean
contacts.
3.
If the armature does not move in, check for voltage across the coil when a key is inserted and
turned. Proper voltage should be 24 VDC + 5 VDC. If this voltage is present, then the relay
coil is burned out. Replace power relay.
4.
If voltage is not present across the coil when a key is inserted and turned, the trouble lies
elsewhere. Check power supply and counter module.
5.
To replace power relay, remove counter modules and bottom bracket. Carefully remove both
through bolts ensuring that no parts (spacers, nuts, washers) are lost. Replace relay,
ensuring that the spacers are properly installed, otherwise the bottom of the printed circuit
board (PCB) will short to the chassis. Reinstall wires to proper terminals, one at a time to
prevent mix-ups.
6.
Replace bottom bracket and counter modules and check for proper operation.
