Error Recovery Procedures
Error Code Tables
8 Locate the actual sensor in error on the unit. The sensor in error is labeled on the unit.
9 Spend a moment looking at the hardware and try to find the cause of the problem.
10 After investigating the cause of the error, now perform the steps suggested in the Solution
column.
11 Press PAUSE/RUN to resume routine operations. Pay attention to the area around the sensor that
generated the error. Ensure that the error has been resolved.
12 If the problem persists, repeat the procedure.
13 Call your Beckman Coulter Representative for any unrecoverable errors.
Error Code Tables
The Error Code tables describe error messages generated by the LH 1500 Hematology Automation
System. The tables provide the system error codes, the related sensor, a location reference point on
the appropriate schematic diagram and a brief explanation of the possible problem and possible
solutions.
1.
Keypad Display: Contains the codes displayed on the keypads located at each unit of the system.
2.
Sensor: Contains the alphanumeric codes as they appear in the Line Controller's Error Log.
These codes, (for example, "SN50") refer to specific sensors.
3.
Problem: Provides a description of the cause of the error.
4.
Sensor Diagram: Provides the name and location of the appropriate schematic diagram.
5.
Grid Ref (Reference): Contains the reference position of the sensor on the appropriate
schematic diagram.
6.
Solution: Provides a way to resolve an error condition.
Sensor Codes
The sensor codes provide definitions of the alpha portion of the codes found in the Sensor column
of the Error Code tables and Sensor diagrams.
1. AM = AC synchronous motor
2. AS = Magnetic autoswitch
