5 PNEUDRI MiDAS

Service Indication Sequence

& Alarm

During operation, PNEUDRI MiDAS Power On

(yellow) LED and Check (Green) LED indicators

will illuminate, remaining in this configuration for

11500 hours. At this time, the Warning (Yellow)

LED will illuminate and cancel the Check (Green)

LED. This signals the user to order service

replacement components at the optimum time.

500 hours later (a total of 12000 hours from initial

start up) the Service (Red) LED will illuminate and

cancel the Warning (Yellow) LED, the Audible

Alarm housed inside the display will sound

intermittently (every 6 seconds) drawing attention

to the need for a service.

Operation

Compressed air enters the integral pre-filter

and passes into the left hand chamber (Column

A) where the air is dried before passing to the

application.

A small amount of dry purge air is used

to regenerate the right hand chamber (Column

B) which is wet, using the PSA (Pressure Swing

Adsorption) method of regeneration, venting

the saturated air to atmosphere under

pressure. The same regeneration air is also

used to “back flush” the integral filter to

prolong its working life.

Prior to changeover, the right hand chamber

(Column B) enters repressurisation where the

exhaust valve is closed to allow pressure to

increase. This process ensures a smooth

uninterrupted changeover, preventing the loss

of any system pressure, before the process

repeats itself.
