Troubleshooting 

7.1  Troubleshooting using the PLC-Interface-Module PLC-A 

The 

PLC-Interface-Module 

provides a Warning and an Error signal. The source of error, however, cannot be 

identified. In case of a system error, use the 

Levitronix

®

 Service Software

. 

 

7.2  Troubleshooting using the Levitronix User Interface LUI-A 

The 

Levitronix Handheld User Interface

 does not display warnings. In case of an error the pump stops and the 

handheld displays a specific error message. It is also possible to read the last error that stopped the pump. 
After a controller restart or reset the error information is removed. After a reset or restart the error information 
is canceled (this can be different for other firmware configurations). 

 

7.3  Troubleshooting using Controller LEDs 

The controller has the following Status LEDs: 

 

LED designator 

Color 

Description 

“DSP power on” 

Green 

LED is on if supply voltage of signal electronics is 
present. 

“Reset active” 

Red 

LED is on during startup of the Digital Signal 
Processor and when the reset button is pressed. 

“Power output not active” 

Green 

LED is on if the switched output stages of the 
controller are disabled. 

“Power on” 

Red 

LED is on if the voltage supply (5 V and 12 V DC) for 
the power drivers is present. 

Table 14: Controller LC325P status LEDs 

 
 

7.4  Troubleshooting with Service Software 

The 

Levitronix

 Service Software

 allows communication with the pump system in connection with a PC and 

the 

RS232

  interface  of  the 

LC325P

  controller.  The  software  can  be  used  for  performing  detailed 

troubleshooting. For usage of the Service Software refer to the 

Service Software User Manual

 (document #: 

PL-2034-00

), which is available in the download section on the Levitronix Web-page or contact the 

Levitronix

 

Technical Service Department

 (see under 

Section 8

).
