Change operation – parametrisation mode
To change from operation to parametrisation mode and vice versa, push ENTER
button for minimum of 3 seconds. Back to operation mode with menu “save”.
Indication of data logging
A flashing unit symbol (star) in the display shows that data is received and the device
is working.
Password input
The default/delivery setup is 0000. In this configuration the password input is not
activated. To activate the password protection (menu 15) change the 4 digits into your
choosen numbers (e.g. 1234) and press ENTER.
Please keep your password in mind for next parameter change! Due to a new parameter
setup the password is requested.
Switching function normally open or closed
can be selected via menu only.
Relais output
250 VAC / 0,1 A – 220 VDC / 0,1 A
30 VAC/DC / 0,5 A
At different relay and supply voltages (24 VAC/DC)
the cable installation must be considered
(see “Information for Installation”) !

All pressure switches require a 24 VAC/DC power supply. The electrical wiring must be
realized via the integrated Ex-e terminal box acc. to ATEX. The terminals’ type of protection
is “Increased safety Ex-e”.
Attention: Before opening the terminal box cover, the supply voltage must be shut off!
The supply has to be connected at terminals 1 (
−
/~) and 2 (+/~).
The start-up bypass delay (AUB) can be activated by bridging terminals 2–3. Activation is
indicated by a flashing green LED.
...Bin-P-... pressure switches are equipped with a zero point compensation to adjust the
module to the installation position.
The pressure nipples P+ / P− must be connected with
a short circuit tube and the zero point compensation performed by following the menu for
parametrisation (menu 14).
Before starting the zero point compensation, the device should be connected to power
supply for a minimum of 15 minutes to reach the uniform working temperature!
A. Installation, commissioning, maintenance
All national and international standards, rules and regulations must be complied with.
Certified apparatus must be installed in accordance with manufacturer instructions.
If the equipment is used in a manner not specified by the manufacturer, the safety protec-
tion provided by the equipment may be impaired. For electrical installations design,
selection and erection, EN/IEC 60079-14 can be used.
Attention: Apply all Ex rules and regulation before opening the internal terminal
box. Do not open cover when circuits are live!
Draw the wiring cables through the cable glands. For connection use the internal Ex-e
approved terminal box and connect equipotential bonding.
After connection install the cables in a fixed position and protect them against mechanical
and thermical damage. Close all openings and ensure IP protection (min. IP66).
Avoid temperature transfer and ensure not to exceed max. ambient temperature! For
outdoor installation a protective shield against sun, rain and snow should be applied.
After mounting and installation a zero point compensation must be done to ensure
correct measurement results (see description).
Sensors are maintenance free. An annual inspection is recommended. For electrical
installations inspection and maintenance, EN/IEC 60079-17 can be used.
Clean with damp cloth only.
Ex sensors must not be opened and repaired by the end user.
B. Long cabling
We recommend using shielded signal wires and to connect one end of the shield to the
...Bin-... terminal box.
C. Separate ground wires
For supply and signal wires use separate grounds.
D. Relais output
Wires for safety extra-low voltage must be installed separately from other circuits. At
24 VAC/DC only supply and signal wires are permitted in one cable, in all other cases
use separate or double isolated cables. An over-current protection fuse < 10 A has to
be provided by the installer.
