2.7 I-Controller Level 3 –
(Optional on 200-750 scfm models)
Dryers upgraded with the optional I-Controller Level 3
include text messaging on the Vacuum Fluorescent Text
Display (VFTD), Alert/Alarm condition display panel
warning lights, process diagram LED indicator lights,
Demand Operated Condensate Drains(s) and SURE-SAVE
Heat Reliever as standard features.
Programming, Start-up and, Operating Instructions
Dryers are pre-programmed in accordance with the
manufacturers recommendations. Programming details
are listed within Table 1.
NOTES:
a) Programming can be accomplished while dryer is in
either the ON or OFF mode.
b) The OPERATION sub-directory list automatically scrolls
sequentially every 3 seconds. Press the (ENTER) key
repeatedly to scroll manually.
2.6 SURE-SAVE Cooling Injection
(Optional: 125-750 scfm model)
Standard: Models with I-C Level 3 Controller
Dryers outfitted with the SURE-SAVE option automatically
protect the refrigeration compressor from damage due
to excessive inlet air temperatures. A temperature sensor
continually monitors the compressor operating
conditions. If the temperature exceeds standard design
conditions, the SURE-SAVE cooling injection valve
automatically redirects cooling energy back to the suction
side. This allows continued operation with an elevated
pressure dew point rather than initiate a high
temperature shutdown. To protect the dryer, high inlet
air temperature shutdown will occur if inlet air
temperature exceeds 140
