SECTION 6 DHL HEATLESS REGENERATIVE DRYER
33
The second series of DIP-SWITCHES (DIP D) allows for the setting of the following parameters:
DIP D1
and
DIP D2
Selecting the operating cycle. The dryer
can operate according to different operating
cycles, according to the requested DewPoint
or according to a diagnostic cycle (see Sec-
tion 6.9).
1 OFF and 2 OFF = Cycle -40°C
1ONand2OFF=Cycle-70°C
1OFFand2ON=Cycle-20°C
1ONand2ON=CycleTest
DIP D3
DPD Cycle. It can be used to start the oper-
ating mode with cycle times proportional to
the applied load (if the second DewPoint
probe is installed- optional). Priority must be
given to the selection of DIPs D1 and DIP
D2.
OFF = Not enabled (standard)
ON = Enabled
DIP D4
HI PDP alarm. It can be used to set off the
alarm for a very high DewPoint (if the Dew-
Point probe is installed- optional).
OFF = Not enabled (standard)
ON = Enabled
DIP D5
Use. It can be used to modify the internal
maintenance timer, selecting a work cycle up
to 3000 hours/year or higher (see Section
6.12).
OFF = up to 3000 hours/year
(standard)
ON = over 3000 hours/year
DIP D6 Not Used. —
DIP D7 DewPoint probe.
OFF = probe disabled ON = probe
enabled (standard)
The first series of (DIP U) allows for the setting of the following parameters:
DIP U1
Pressure. The SHDC-2100 device can
operate with two different pressure
ranges, according to the operating limits
used to design the dryer (Standard Max.
10,3 barg; optional Max. 16 barg).
OFF = Low pressure - Max. 10,3 barg
(standard)
ON = High pressure - Max. 16 barg
DIP U2
Fail to switch alarm. It can be used to
enable the pressure switches to control
the “Fail to Switch alarm” function.
OFF = Not installed (standard)
ON = Installed
DIP U3
FT Filter Management. Two differential
manometers are connected to the inlet
and outlet filters. They show the level of
clogging of the cartridge and through an
electric contact they transfer this signal to
the SHDC-2100 device. The signal can be
managed like a normally closed contact
(pos. OFF) or an open contact (pos. ON).
OFF = contact closed → filter OK (stan-
dard)
ON = contact open → filter OK (reverse)
DIP U4 Not used. —
