Start-up
BSP-MT 1-8/D3
25
LED Economy cycle (4)
This LED is only relevant in units that are equipped with the optional dewpoint-sensing
control. The diode lights up when the dryer is switched on and in the standby phase and no
regeneration air is required.
Start up dryer
Warning against sudden air ejection!
During expansion the pressure is released suddenly through the muffl er:
◊ A loud cracking noise occurs which can injure your hearing.
◊ Particles carried in the air fl ow act like bullets and can injure your eyes or
skin.
Always wear eye and ear protection, therefore, when you are in the vicinity of
the dryer!
Hazard due to a sudden release of pressure!
Never remove any parts of the dryer, or manipulate the same in any way, for as
long as the plant is still pressurised! A sudden escape of pressure may cause
serious injuries.
Before carrying out any work on the dryer, fi rst depressurise the plant.
◊
Carry out all prescribed tests and checks.
◊
The factory settings on the control board in the switchbox must not be changed on any
account without prior approval by the manufacturer.
◊
Before start-up, ensure that no tools or other foreign parts have been left lying in a part of
the dryer where they might pose a hazard to the dryer being started up.
Open compressed air supply and switch on dryer
For start-up, please proceed in the sequence shown here.
Ensure that the compressed air inlet and outlet valves installed by the owner are closed
(see installation example on page
19
).
Ensure that the compressed air system upstream of the dryer is pressurised. If necessary,
pressurise (switch on compressor).
Slowly open compressed air inlet valve!
Avoid sudden pressure build-up in any circumstance! If pressure builds up too
fast, this may cause damage to the dryer. Therefore, the compressed air inlet
valve must always be opened quite slowly!
Slowly open the compressed air inlet valve, installed by the owner, upstream of the dryer.
Switch on dryer: to this end, set the ON/OFF switch to
I
If the dryer is taken into operation for the fi rst time, or after a change of drying agent, the
following intermediate step is meaningful. In the case of a restart situation, the following
intermediate step can be skipped.
Operating the dryer for the fi rst time (or after a change of drying agent) separately
Depending on the transportation and storage conditions, the drying agent in the chambers
can already be loaded with humidity from the environment. At each fi rst start-up it makes
sense therefore to operate the dryer from some time separately from the compressed air
system. This causes the drying agent in each chamber to be regenerated repeatedly and thus
to be prepared optimally for the take-up of humidity.
