2.1 Introduction
General description
The dryers are built to remove moisture from compressed air for industrial purposes. All units
are designed for indoor use.
Automatic control of the dryer
The regulator maintains the pressure dewpoint between programmable limits automatically
by defining the switching time.
A number of time-based automatic start/stop commands may be programmed
(see section Programming clock functions). Take into account that a start
command will be executed (if programmed and activated), even after manually
stopping the dryer.
Protecting the dryer
Shut-down warning (Elektronikon only)
If the dryer inlet temperature exceeds a programmed value, this will be indicated to
warn the operator.
