MAINTENANCE AND TROUBLE SHOOTING

 

 

6.1 Cleaning 

 
 

The switch can be cleaned by soaking, spraying solvents or detergent-and-water onto the 
sensor tubes, or by ultrasonic cleaning.   

 

 

Lime deposits can be safely removed by soaking in 20% hydrochloric acid.  Warming to 
150°F is permissible to speed this process. 

 
 

For unusual cleaning problems, call DELTA M and determine the exact materials of 
construction and chemical compatibility before using strong acids or unusual cleansers. 

 

**IMPORTANT** 

 DO NOT SANDBLAST OR ABRASIVE CLEAN THE SENSING PROBES.  

THE SENSING  PROBES COULD BE DAMAGED BY ABRASIVES. 

 
6.2 Troubleshooting 

 
6.2.1 

Power and Continuity Verification 

 

1.  Turn power off to the microtuf

®

 Switch. 

 

2.  Remove the instrument enclosure cover (ccw). 

 

3.  Loosen the two PC captive screws (see Figure 4.0 for location). 

 

4.  Unplug the PC board from the instrument enclosure by pulling straight out on the 

transformer. 

 

5.  Reapply power and verify correct voltage at pins 7 (positive for DC) and 8 (negative for 

DC) of TBB (see Figures 6.0 or 7.0). 

 

6.  If voltage is correct, verify the fuse (F1) on the PC board is not blown (See Figure 8.0). If 

fuse is not blown proceed to 6.2.2. 

 

7.  If fuse is blown replace with appropriate value (See 7.0 Specification).
