5.4 Troubleshooting

NOTICE:

If the pump should become faulty, contact the dealer

from whom you purchased the pump. Repair must be left
to personnel who have undergone Hitachi High-
Technologies Corporation technical training since
potential hazards are involved.

5.4.1 Error Messages and Proper Measures

WARNING

Beware of Electric Shock!

Before removing the pump cover for parts replacement, etc., make
sure to turn OFF the power switch and disconnect the power cord
from the receptacle.

(1) If an abnormality occurs on the Model L-2130 pump, an

error message appears on the LCD (Liquid Crystal Display).
Error displays result from either the detection of a fault
during the self-diagnostics at power up (upon
[INITIAL]ialization), or from a problem which occurs
during operation.

Fig. 5-1 shows error detecting functions and the error
messages.
