Troubleshooting:
Issue
Possible Cause
Corrective Action
1) Turntable does not
rotate
a) No power supply voltage
b) Speed control on lowest setting
c) No signal from pedal control
d) Motor controller fault or
defective motor controller
e) Chain is broken or slipping
a) Check outlet for 115V power. If outlet lacks
power, determine cause of power loss
before restoring power to the wrapping
machine. [NOTE: If turntable power cord is
plugged into the pigtail cord of the powered
mast, confirm that powered mast cord is
plugged into a wall socket.]
b) Increase turntable speed using the speed
c) Check continuity of foot pedal and the
cable connected to it.
d) Check the display on the Delta motor
speed controller for a fault code. If a fault
code is displayed, contact Vestil
Manufacturing (phone number on cover of
this manual).
e) If fan of drive motor spins but table does
not rotate, release the foot pedal; then
inspect the chain.
2) Turntable cannot rotate
without assistance,
rotates more slowly
while loaded, or does not
achieve set speed
f) Chain is broken or slipping
f) If fan of drive motor spins but table does
not rotate, release the foot pedal; then
inspect the chain.
3) Mast motor or control
enclosure hums,
chatters, or buzzes, and
the stretch wrap holder
moves slowly or not at
all.
g) Excessive voltage drop to motor
due to:
•
Inadequate wiring;
•
Wire run too long; or
•
Incoming voltage too low.
h) Damaged mast or stretch wrap
holder
i) Low control voltage or bad
connection in control circuit
g) Check power supply for adequacy. Check
incoming voltage while motor runs. If the
voltage is too low, correct by
•
Installing circuit with larger wire;
•
eliminating extension cord(s); or
•
installing a buck/boost transformer.
h) Examine mast and holder for damage or
excessive wear.
i) Confirm 24VAC at transformer secondary.
Examine all wiring and connections in the
mast for looseness, etc.
4) Powered stretch wrap
holder does not respond
to commands (UP and
DOWN)
j) Low control voltage or bad
connection in control circuit
k) Blown transformer fuse
l) No power supply voltage
m) Mast limit switch engaged or
malfunctioning
n) Control relay 1 CR contact is
burnt
o) Control relay 1 CR is loose
j) Confirm 24VAC at transformer secondary.
Examine all wiring and connections in the
mast for looseness, etc.
k) Test with meter; replace if bad (replace
with same fuse type and ampere rating)
l) Check outlet for 115V power. If outlet lacks
power, determine cause of power loss
before restoring power to the wrapping
machine. [NOTE: If turntable power cord is
plugged into the pigtail cord of the powered
mast, confirm that powered mast cord is
plugged into a wall socket.]
m) Inspect and test switch, Replace if bad.
n) Examine contact. Clean contact or replace
relay as necessary.
o) Verify that the relay is firmly in place.
5) Powered stretch wrap
holder elevates on
command but does not
lower
p) Control relay 2 CR is loose
q) CR 2 is defective
r) Bad connection in control circuit
s) Physical blockage in mast
p) Confirm that the relay is firmly in place
q) Examine and test 2 CR. Replace if
necessary.
r) Test all parts of circuit with meter
s) Determine cause of blockage and remove
it from the path of the holder.
