SECTION IV MAINTENANCE
GENERAL SYSTEM CLEANING:
Disengage the A T3 from its power source before any cleaning. The unit can be cleaned with a soft cloth
dampened with water. A mild detergent may be used if necessary. Do not allow water inside the unit.
Also be sure that no water remains near the power connections to eliminate the possibility of electrical
shock.
TROUBLESHOOTING
Below is a preliminary list of the steps to take in diagnosing a system problem.
If there are no system outputs or display:
•
Make sure that there is power to the A T3.
•
Ensure that the system power switch is in the ON position.
•
Check that the circuit breaker is not tripped. Press it to reset.
If there is erratic data or off-scale values in the absence of an upset condition:
•
Ensure that the cables to the preamplifier are connected; check to see if they are shorted.
•
Make sure that the pipeline is full.
•
Ensure that the preamplifier is firmly attached to the transducer.
If none of these items correct the problem, go to the "Waveform" menu and verify that the system output
is normal. Follow the system setup procedure; readjusting the receiver window, detection threshold, or
power level may correct the problem. Contact your Customer Service Representative if the problem
cannot be found.
REPAIR AND SERVICE
If you have determined that your A T3 is in need of service or repair, do the following before calling
Monitek for service information:
Leave the system in its malfunctioning configuration.
Have a description of the malfunction readily available.
Have a list of the equipment's serial numbers.
SHIPPING INSTRUCTIONS
If it becomes necessary to ship all or part of the AT3 system back to the factory for repair, be sure that it
is packaged with care. For return shipments it is best to use the original packaging materials. Damage
incurred during shipment is not covered under warranty; therefore, it is suggested that all shipments be
properly insured.
