Pfeiffer Vacuum DCU 310 - 8 Malfunctions; General; Error Codes

8 Malfunctions
8.1 General
Vacuum pump and electronic drive unit malfunctions always result in a warning or error message. In
both cases, the LC-display on the DCU shows an error code. LED on the electronic drive unit and on
the DCU illuminate for the corresponding status.
No LC-display
●
Absence of the LC-display is possibly an indication that attachment of the con-
nection cable is faulty:
─
"DCout"
─
"RS485"

"X3"

"ACin"
8.2 Error codes
In addition to the device-specific waning and error messages for an electronic drive unit, the DCU also
features its own messages. Errors (** Error E–––– **) always cause the connected peripheral devices to
be switched off. Warnings (* Warning F –––– *) do not cause components to be switched off.
Handling of fault messages
1.
Read out the error codes via the display and control panel or the PC.
2.
Remove the cause of the fault.
3.
Reset the error message with parameter [P:009] or by pressing the button on the DCU.
