FIGURE 1: Air Connection Schematic
Start-up / Check
1. Ensure that all air line fittings are properly connected.
2. Pressurize system
3. Check air line fittings for leaks and repair leaks.
4. Observe operation of the DA Series for proper function as described in the
DA Series Operation /Cycle section.
DA Series operation/Cycle
1. The Micro Logic Timer (MLT) controls drying and regeneration cycles of the
DA Series by energizing and de-energizing the “air control valve” of the DA
Series at 120 second intervals. A green LED will intermittently light during
one (1) cycle and the light continuously during alternate cycle.
2. The DA Series “air control valve” controls air-flow direction through the DA
Series. During operation one desiccant cartridge is drying air and the other
cartridge is being regenerated.
3. During operation there will be a light flow of air from ONE exhaust port of
the DA Series. This is normal regeneration, air flow will alternate (every
120-seconds) from one exhaust port to the other in conjunction with the
MLT cycles. There will be a momentary burst of air from one of the
exhaust ports, this is normal and is beginning of the regeneration process.
