CARRIER WON'T RUN EITHER DIRECTION:
This presumes that the power
LED
works properly. If it does not, go to the paragraph on
"NOTHING WORKS"
. First replace the
MOTOR FUSE.
Replace it only with an AGC10 fuse.
This is a U.L. listed fuse rated for 120vac. Do not use fuses rated for only 32vac. If the carrier
does not run, proceed to the paragraph
"CARRIER WON'T RUN IN WHEN INSIDE RECALL
BUTTON IS DEPRESSED".
If the carrier still won’t run, replace the
DRIVE ASSEMBLY
CARRIER WON'T SHIFT INTO HIGH SPEED:
Adjust the speed shift points as instructed on page 9. If the carrier will still not run in high speed,
monitor the voltage to the motor at the connections to the motor in the power module. Note:
These connections are fully insulated quick connects; however, there is room to carefully slip
meter leads into them sufficient to make contact for measuring purposes. The motor must be
connected for this test. Run the carrier. The voltage should be approximately 36vdc in slow and
88vdc in high. If the voltage changes and the speed don’t, inspect the machine for anything
causing excessive drag such as damaged tape, bows, sags or misalignment in the track or bad
bearings in the surround. If the voltage doesn't change, observe the
CHAIN LED
. This
LED
should flash on twice for each revolution of the motor. If it does not, check SJ1 connection on the
control board. If connection is O.K., replace the
DRIVE ASSEMBLY.
If it still does not, replace
the
CONTROL BOARD.
CARRIER IS IN HIGH SPEED IN THE VERTICAL SECTIONS:
Adjust the speed shift points as instructed on page 9.
CARRIER OVERRUNS STOP POSITION ON INSIDE END:
First, insure that the carrier is traveling in the slow speed in the vertical section. Check to insure
that the gap between the magnet and the black switch is 1/8" or less. With the carrier at the stop
position and the magnet positioned on one of the stop switches, check the
LED
labeled T-L. It
should be on. If it is not, replace the
SWITCH;
if it is still not on, replace the
CONTROL BOARD
.
CARRIER OVERRUNS THE CAR & TRUCK STOP POSITIONS ON THE CUSTOMER
END:
First, insure that the carrier is traveling in the slow speed in the vertical section. Check to insure
that the gap between the magnet and the black switch is 1/8" or less. With the carrier at the stop
position and the magnet positioned on one of the stop switches, check the
LED
labeled T
-
L. It
should be on. If it is not, replace the
SWITCH;
if it is still not on, replace the
CONTROL BOARD.
RELAYS AND BRAKE CLICK; MOTOR WON’T RUN:
There is a brake interlock switch, which prevents the motor from running unless the brake fully releases.
Check J11 connection on the Control Board. If you still experience this problem, please consult the
factory.
