2 Function and application
The pressure sensor SDE5 is intended for the proper monitoring of the pressure
inthe compressed air system. The SDE5 converts pneumatic pressure values into
apressure proportional voltage. Depending on the design of the pressure sensor,
this signal is converted into a digital switching signal (SDE5-…-P-…/SDE5-…-N-…)
or it is amplified for an analogue output (SDE5-…-NF-…-V).
The monitored pressure values record either the relative pressure or the
differential pressure (SDE5-…-Z-…).
The pressure sensor with switching output closes or opens a circuit when the
switching pressure is reached. The switching element function is preset at the
plant and can only be modified with the SDE5-…-FP-…. The SDE5 is available with
different switch/teach functions (èFig. 2).

3 Requirements for product use
 Use the product in its original status, without any unauthorised product
modifications.
 Observe the specified limits (e.g. operating medium, pressures, forces,
temperatures).
 Take into consideration the ambient conditions at the location of use.
 Observe the regulations which apply in your location (e.g. from trade
associations or from national institutions).
 Remove everything used for protection during transport such as protective wax,
films, caps and cardboard boxes. The material used in the packaging has been
specifically chosen for its recyclability (exception: oil-impregnated paper =
residual waste).
 The device is intended for use in an industrial environment. Measures may need
to be implemented in residential areas for interference suppression.
 Remove dirt particles in the supply lines by blowing out the pipes and hoses.
This protects the device from premature failure or heavy wear.
Range of applications and certifications
The information in this section, in combination with the UL marking on the product,
must be observed in order for there to be compliance with the certification
conditions of Underwriters Laboratories Inc. (UL) for USA and Canada. Observe the
following English-language remarks from UL:
This device is intended to be used with a Class 2 power source or Class 2
transformer in accordance with UL1310 or UL1585.
As an alternative a LV/C (Limited Voltage/Current) power source with one of the
following properties can be used:
– This device shall be used with a suitable isolating source such that the
maximum open circuit voltage potential available to the product is not more
than 30 V DC and the current is limited to a value not exceeding 8 amperes
measured after 1 minute of operation.
– This device shall be used with a suitable isolating source in conjunction with
afuse in accordance with UL248. The fuse shall be rated max. 3.3 A and be
installed in the 30 V DC power supply to the device in order to limit the available
current.
Note that, when more than one power supply or isolating device is used,
connection in parallel is not permitted.
In determining the acceptability of the combination, the following details are to be
examined:
– The suitability of the final mounting is to be determined.
– The devices are to be mounted in an enclosure with adequate strength and
thickness.
– The devices have not been examined for field wiring. The suitability of the final
application is to be determined.

Note
The pressure sensor SDE5 on the series MS service unit is already permanently
attached and pneumatically connected when delivered.
4.1 Mechanical system
 If several wall holders are used: push
the dovetail of wall holder 1into the
connecting slot of the next wall holder
(press out lug 2). 1

Fig. 5
 Mount the first and the last wall holder
with 2 screws each (4 mm) at the
designated positions.
 If more than 3 wall holders are being

holder with 2 screws each (4 mm).
Fig. 6
 Press the SDE5 into the wall holders.
Iffitted correctly, all four spring clips 3
will latch audibly into place.
The lug of wall holder 4can be broken

Warning
Only use power sources which guarantee reliable electrical isolation of the
operating voltage according to IEC/DIN EN 60204-1. Also observe the general
requirements for PELV power circuits according to IEC/EN 60204-1.
Note
Long signal lines reduce the immunity to interference.
 Make sure that the length of the signal line is always shorter than 30 metres.
The tightening torque for the cap nut at the plug connector is max. 0.3 Nm.

Caution
After teaching, the values are written to the internal memory. If the saving
process is unexpectedly aborted (e.g. from a power interruption), the transfer
process to the memory can not be completely carried out and the device
becomes unusable.
 Ensure that there is power supply to the device for at least 10 seconds after
teaching.
Note
Unintended pressing of the Edit button can cause an accidental alteration of
thepreset switching pressure (e.g. setting the SDE5 to a switching pressure of
0 bar/0 MPa when the operating pressure is missing).
Definitions:
– Pressure p: relative pressure or differential pressure (also vacuum with
SDE5-V1/B2).
– Switching pressure SP: pressure p at which the SDE5 switches.
– Teach pressure TP1, TP2: pressure p at time of programming.
