Honeywell Work Light DR4300 User Manual

Table 7-3 explains how to troubleshoot a pen trace problem.  

 

Check the ink cartridge for proper 
installation. 

Reposition or replace the ink cartridge as 
described in Section 6 – Routine Maintenance.  

If the pen arm is severely warped, replace the 
pen arm as described in Section 9 – Replacing 
Hardware Assemblies. 

Check that the chart agrees with the 
actuation type and chart set up. 

Replace wrong chart with correct chart. Refer to 
Section 3 – Configuration, Startup, and Operation 
of Recorder without Display for instructions for 
viewing the configuration.  

See Section 6 – Routine Maintenance for 
instructions for replacing the chart. 

Check the pen alignment. 

Follow the procedure in Subsection 7.4. 

Look at printed circuit assembly (PCA) for 
the pen to see if the red* LED is lit. This 
LED is lit when the PCA failed a self-
diagnostic, or an out-of-range input has 
been detected. (Flashing green LED is 
OK, it indicates that the processor is 
active.)    

Press the reset switch SW2. The PCA will be 
initialized. If the problem was a software error, 
the error may be cleared by the reset. 

 

*For Recorders with a display, the red LED is 
used by an internal control signal and is not a 
fault indicator.  

Check the sensor for the proper type and 
its ability to function. 

Verify the input configuration data and operation 
of the sensor. 

Measure input signal at TB2 or apply calibration 
source to verify input signal. 

Replace the servo plate assembly. 

Refer to the replacement procedure in Section 9 
– Replacing Hardware Assemblies. 

Replace the printed circuit assembly for 
the pen with the problem. 

Refer to the replacement procedure in Section 9 
– Replacing Hardware Assemblies.
