conditions of Underwriters Laboratories Inc. (UL) for USA and Canada. Observe
the following information in English by UL:
In determining the acceptability of the combination, the following details should
be examined:
– The mounting suitability shall be determined in the enduse.
– These devices shall be mounted in an enclosure having adequate strength
and thickness.
– Devices should be used within its recognized ratings as specified under sec
tion RATINGS.
– Devices have to be supplied from:
– A Class 2 power source or Class 2 transformer in accordance with UL1310
or UL1585, or
– An isolating device such that the maximum open circuit voltage potential
available to the circuit is not more than 30 Vdc and the current is limited
to a value not exceeding 8 amperes measured after 1 minute of opera
tion, or
– 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 Vdc
power supply to the device in order to limit the available current.

4.2 Function
4.2.1 Functional principle
The SDE5 converts pneumatic pressure values into a voltage proportional to the
pressure. Depending on the design of the pressure sensor, the voltage signal is
converted into a digital switching signal (SDE5...P.../SDE5...N..) or amplified
for an analogue output (SDE5...NF...V).

The monitored pressure values record either the relative pressure or the differen
tial pressure (SDE5...Z...).
SDE5 with switching output: when the switching point is reached, the pressure
sensor closes or opens a circuit.
The SDE5 is available with different switch/teach functions . The switching func
tion is preset ex works and can only be changed for the SDE5...FP... .
5 Mounting
5.1 Mount SDE5 with wall bracket
NOTICE!
Accumulation of condensate in the product can impair its functionality.
• Install the product in such a way that condensate from the compressed air
lines cannot collect in the product.
Mounting several wall brackets
1Dovetail
2Strap
Fig. 3 Connection of wall bracket
1. Push the dovetail of the wall bracket into the connecting groove of the next
wall bracket (push away the strap).
2. Fasten first and last wall bracket with 2screws each (Æ 4mm).
If more than 3 wall holders are being used: mount every second wall holder
with 2screws each.

3. Press SDE5 into the wall bracket.
Ä4 snap latches engage audibly.
Individual mounting
• To make it easier to see the LED light, break out the strap of the wall bracket
when mounting individually.
6 Installation
6.1 Pneumatic installation
Push-in connector
Fig. 5 Pushin connector
Push-in connector at one end
• Mount the hose to connection 1.
Push-in connector at both ends
1. Check pressure conditions.
With the pressure sensor for differential pressure (SDE5...Z...), the higher
pressure must be applied to port 1 (differential pressure = p1  p2).
2. Mount the hoses to connection 1 and 2.
6.2 Electrical installation
WARNING!
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
• Observe IEC602041/EN602041.
1. Use signal lines that are shorter than 30m.
2. Configure binary outputs according to the wiring è Tab. 4 Pin allocation.

NOTICE!
Voltage interruption during the storage process will make the product unusable.
After teaching, the values are written to the internal memory. If the save process
is aborted due to power interruption, the transfer process to the memory cannot
be completely carried out and the device becomes unusable.
• Ensure power supply for at least 10seconds after teaching.
