While operating in the leak detection mode, the display will provide information which
will support the operator using the HLD5000. Besides messages relating to leak
detector settings also warnings and error messages may be displayed.
The HLD5000 is equipped with comprehensive self-diagnostic means. If a fault
condition is detected by the controller board this is indicated via the display to the
operator.
Errors are events which force an interruption to the measurement sequence and
which the HLD5000 is not capable of remedying on its own. Errors are displayed in
plain text on the display. The error sound is a two-tone sound.
The error message can be erased by pressing the "OK” key.
As long as an error status exists, a warning triangle comes up in the lower line of the
display.
An overview over the error messages which may occur while the machine is in use
and possible remedies are listed below.
A list of all error messages as well a notes for troubleshooting is provided in the
Repair Instructions (kipa40e1).
