13. TROUBLESHOOTING
13.1 INTRODUCTION
This chapter is a guide to solve the most common problems that can occur while using the presetter. Each
problem that can be detected is mentioned together with a series of checks that have to be carried out and
the possible corrective actions that can solve them. Obviously, the following list is not complete: in case
you need assistance, please contact your local distributor.
13.2 PROBLEMS, CAUSES AND SOLUTIONS
PROBLEM: The presetter does not turn on.
CAUSE: The general power supply is missing.
SOLUTION: Check the connection to the external power supply circuit
Check possible external fuses and/or switches and, if they are damaged, replace them.
CAUSE: The Preset power supply is missing.
SOLUTION: Control if the power supply plug has been correctly introduced into the rear panel of the
Preset (see installation par. 5.7);
check the operation of the feeder by measuring if there is a 24Vcc voltage at the output and
repeat the test when the Preset is connected. If the 24Vcc voltage is present, please contact
the assistance service.
PROBLEM: Difficulty in displacing the Z-axis towards the top.
CAUSE: The spring of the balance weight is damaged.
SOLUTION: Remove the case of the spring to be found in the top of the column, check the damage of
the balance-weight spiral spring and then contact the technical assistance service to replace
the component.
PROBLEM: The count is incorrect but supplies repetitive measurements.
CAUSE: The linear compensation machine parameter is incorrect.
SOLUTION: Restore the standard settings (see par. 8.7.3).
PROBLEM: The count is incorrect, and the measurements are not repetitive.
CAUSE: The vision system reticule, due to a collision, is not parallel any more to machine axes
SOLUTION: See the corresponding trouble afterwards.
CAUSE: Faulty E236+ electronic equipment or detection system.
SOLUTION: See the following trouble
PROBLEM: Axes count is not carried out.
CAUSE: Faulty E236+ electronic equipment or detection system.
SOLUTION: If the defect relates to both axes, probably the fault is to be found in the E236+ electronic
equipment; otherwise the fault is caused by the measurement system or cable. Please
contact the technical assistance service to replace the component.
CAUSE: Due to power supply loss while saving the data, the content of the memory can be altered.
SOLUTION: See the solution for the following trouble
