5.9 Fuse 

Replacement 

Three fuses protect the Binary Solvent Delivery Module. Two of 

the fuses are located in the power entry module at the rear of the 
cabinet and are in series with the AC input line. The other fuse is 
located on the circuit board and is in series with the 24  VDC supply. 
 

Troubleshooting the fuses is straightforward. If the power cord is 

plugged in and the on/off power entry switch is on and the display 
does not light, check the two fuses in the power entry module. To gain 
access to these fuses, gently pry off the cover plate with a small flat-
bladed screwdriver. Replace with fuses of the correct rating: 2 A slow-
blo for 120 VAC systems.
