Honeywell Work Light DR4300 User Manual

You can test the recorder’s mechanical operation by running a step test. This test is initiated using the 
keypad as described in Table 4-21.  

This test prints a step pattern, which is independent of any chart settings, with horizontal lines drawn by 
both pens at each 10 % increment on the chart (see Figure 4-5).  

 

SHOCK HAZARD 
When the unit is powered a potentially lethal shock hazard exists at the AC line connections at TB1 on 
each printed circuit assembly (behing the chart plate). Make sure the unit power is disconnected before 
starting the procedure. More than one switch may be required to de-energize the recorder. 
Failure to observe this precaution can result in exposure to a potentially lethal shock hazard.

 

 

The test will run for one complete revolution of the chart before it stops itself. The chart revolution for the 
test takes approximately 2 minutes, regardless of configured chart speed. However, the test can be 
terminated at any time by pressing the  DISP   key. 

At power-up the recorder runs self-diagnostics on the printed circuit assembly for each pen. See Section 
4.5.1.4 and Section 8 – Troubleshooting and Pen Alignment of Recorder with Display for more information 
about these diagnostic tests. 

 

Use the procedure in Table 4-21 to run the step test.  

 

Make sure the cap is removed from the tip of each pen and the chart is 
installed. (If you plan to store or ship the recorder, save the protective caps 
for the pen tips. Replace them if the recorder is taken out of operation.) 

 

, swing out the chart plate and 

set SW5 on the printed circuit assembly on the right (pen 1) to the setup 
position, toward the top of the board. 

Be certain that the Lockout level is "CAL" or "NONE". The self-test will not 
run otherwise. 

 

Apply power to the recorder. 

 

Until INP 1 indicator is lit on the left side of the operator interface.
