A-Type Error General Troubleshooting
Each of the specific A-type errors discussed below causes the UD-710 automatic
IRRADIATOR
to cease
automatic operation. No dosimeters are read after an A-type error occurs until the problem is resolved. This type
of error occurs for one of two reasons. First, a timing sensor did not detect a signal within the specified time limit
even though the upper sensor detected the top shelf of the Automatic Magazine Changer. Second, the shelf
location in the
IRRADIATOR
memory was the first shelf, even though the upper sensor did not detect the top shelf.
Troubling this type of error consists of removing any obstacle, checking the mechanism or replacing faulty parts
according to the Service Manual.
A3 Errors
This is a timing sensor error which occurs when a signal is not received within a specified time limit of moving one
shelf up or down even though the rack driving motor is operating. This error is usually caused by something
blocking the magazine rack, failure of the driving motor, failure of the sensor, or failure of the printed circuit (PC)
board of the driving circuit. This error may be resolved by removing any blocking material, checking the
mechanism or its control circuits or replacing any faulty components.
A5 Errors
An A5 error is produced by one of two timing sensor problems. First, an A5 error may be produced when the
magazine end sensor of the loader does not detect a signal within the specified time limit even though the
magazine driving motor is operating in reverse and the magazine sensor of the reader detected the magazine
head. An A5 error may also be produced when the magazine sensor of the
IRRADIATOR
does not detect a signal
within the specified time limit even though the magazine driving motor is operating. The usual causes of this type
of error are something blocking the path of the magazine, failure of either the sensor of the loader or reader, or
failure of the driving motor. This error may be corrected by removing any obstacle, and adjusting or replacing the
faulty components.
