dryer (see appendix) :
l
a machine diagram
l
two LED’s indicating the tower in drying operation.
l
a LED indicating the prefilter drain operation.
3.3 OPERATING CYCLES TIME FROM 5 to 300
Drying time
: 2 min’s
Regeneration time : 1 min 30s
Pressurization time : 30s

When DL1 is lighted, the tower 1 is in drying operation and tower 2 is in regeneration one.
After tower 2 regeneration finished, DL2 is blinking to show that the tank is now in pressurization
stage. After 30 seconds of pressurization, the air dryer operating cycle is inversed that means
tower 1 is in regeneration stage and tower 2 in drying one.
The cycles permutation occurs every 2 minutes. Prefilter condensate drain discharge is
programmed every 4 minutes during 4 seconds. All these cycles times are fixed and not
adjustable by user.
