3.5 Drum Rotor Motor Adjustment
Problem
: The operator reports that the F3Dn makes
an intermittent [in-and-out] grinding or scraping noise
when dispensing fries. The Drum Rotor, Rotor Drive
Shaft or Rotor Motor may be out of alignment.
1)
Determine which Lane is making the noise.
2)
Remove the Hopper only from the Lane in question.
3)
Using a metal object to fool the Basket Present Sensor
and activate a fill cycle on that Lane. Observe and listen
to the operation of the Drum Rotor.
4)
Replace Hopper in that Lane and check hopper hanger
alignment. If OK, proceed to Step 5. If out of alignment,
see Section 3.6.
5)
Roll unit out to allow access to rear service panel.
6)
Disconnect power at outlet. [Pull plug]
7)
Remove screw securing back service access panel.
8)
Using a 5/32” [4 mm] Allen Wrench, loosen the four
Drum Rotor Motor mounting screws.
9)
Shift position of motor right, left, up or down as needed,
to better seat motor gear box shaft in plastic Rotor Drive
Shaft, then retighten motor mounting screws. [You may
need to repeat this adjustment process to ensure good
alignment.]
10) Reconnect unit to power supply.
Test
for normal rotor/motor operation by:
11) Turning ON main power switch & pressing LANE-
POWER touch pad on control overlay.
12) If LOAD READY light is on, position empty fry basket
under hopper and activate loading cycle [if in AUTO
Mode]. In MANUAL Mode, press MANUAL DISPENSE
touch pad to initiate fill.
13) If Fry Hopper is empty, place screwdriver or knife in front
of Basket Present Sensor to trick the dispenser.
14) Position an empty fry basket in the fill chute.
15) If Lane dispenses fries [if present] or if rotor turns
smoothly with out grinding, the unit is working properly.
16) Close up rear service access panel and return F3Dn
Dispenser to normal operating location
.
