7.3 POSSIBLE PROBLEMS RELATED TO THE ARM
The most common problems related to the Arm are:
Symptom
Procedure to follow
There is no Alarm, but the
Arm does not move
-Check the speed of the Hand Command.
-Check if there are limits sets on the movement of the Arm.
-Check if there is something blocking the movement of the Arm.
There is no light in the
screen
-Check the cable for the display.
The system does not start
-Check if all the securities are connected (Hand Command,
Emergency stop, start button).
-Change the cable for the Hand Command.
The arm only moves in one
direction when finding limits.
-Check if there is something blocking the movement of the crane
-Check in the TTL screen to see if the crane detects one of the
magnetic limits even if it is not in the limits position. If so, that
magnetic limit is broken, either the cable is broken/disconnected, or
the sensor is broken.
-In the maintenances chapter it is explained how to bypass the limits
under the operator responsibility.
The arm does not move
when finding limits and it
disconnects itself
-Verify that the locking pin for the arm is released.
In the display appears
“Motor burnt, or motor cable
disconnected”
-Check if the main motor cable is connected.
-Check if the magnetic limits of the arm are arriving at the electronic
box (TTL screen or check that both LEDs of the Relay board are ON
inside the E.B.).
There is a bad movement of
the arm: when the arm is
moved, it jerks.
-Check if there is enough power arriving to the crane. If the crane
has a heavy payload and the movement being done is fast, try to
use a bigger power supply (40A.).
The crane arm drift by itself
-Restart the crane.
-Using the display, calibrate the potentiometer from the Hand
Command (chapter Command adjust 4.2.4.2).
The telescopic arm moves
faster in one direction than
another
-Using the display, calibrate the potentiometer from the Hand
Command (chapter Command adjust 4.2.4.2).
The range of the arm is
different every time the
crane is started
-Depending on how fast the magnetic limit stops detecting this
distance may vary. Once the limit is detected, move slowly out of the
physical limit.
There is an error message
with a mismatch between
the DIP switch and the
equipment
Change the DIP switch on the Electronic Box accordingly as seen in
chapter 6.4.4 Replacement of the Electronic Box.
