1 Intended Applications
The dual pressure switch monitors system pressures and has up to two switching outputs and one
analog output.
The dual temperature switch monitors the temperature of the medium into which the probe is
immersed and has up to two switching outputs and one analog output.
DANGER
The switch may only be used in the specified fields of application.
The temperature must be within the specified ranges, the pressure values and the electrical rating
must not exceed the values specified.
Observe also the applicable national safety instructions for assembly, commissioning and
operation of the switch.
The switch is not designed to be used as the only safety relevant element in pressurized systems
according to DGR 97/23/EC.
2 Safety Instructions
The safety instructions are intended to protect the user from dangerous situations and/or material
damage.
In the operating instructions the seriousness of the potential risk is designated by the following
signal words:
DANGER
Refers to imminent danger to men.
Nonobservance may result in fatal injuries.
WARNING
Refers to a recognizable danger.
Nonobservance may result in fatal injuries, and destroy the equipment or plant parts.
CAUTION
Refers to a danger.
Nonobservance may result in light injuries and material damage to the sensor and/or to the plant.
IMPORTANT
Refers to important information essential to the user.
Disposal
The sensor must be disposed of correctly in accordance with the local regulations for
electric/electronic equipment.
The switch must not be disposed of with the household garbage!
3 Standards
The standards applied during development, manufacture and configuration are listed in the CE
conformity and manufacturer's declaration.
4 Warranty/Guaranty
Warranty
Our scope of delivery and services is governed by the legal warranties and warranty periods.
Terms of guaranty
We guaranty for function and material of the dual pressure and temperature switch under normal
operating and maintenance conditions in accordance with the statutory provisions.
Loss of guaranty
The agreed guaranty period will expire in case of:
•incorrect use,
•incorrect installation or
•incorrect handling or operation contrary to the provisions of these operating instructions.
No liability is assumed for any damage resulting therefrom, or any consequential damage.

5 Installation/Commissioning
DANGER
Only install or uninstall the switch when deenergized (electrically and hydraulically/pneumatically).
Pressure connection and electrical connection must be carried out by trained or instructed
personnel according to state-of-the-art standards.
The switch must only be installed in systems where the maximum pressure Pmax or the maximum
temperature Tmax is not exceeded (see type label).
WARNING
Be aware of the fact that in case of operation with higher temperatures the casing surface may
become very hot!
CAUTION
Mount the pressure switch from bottom to the fitting with a wrench SW 36 (1/4“) resp. 19 with 45
Nm torque.
Do not operate the switch if the switch itself or the connection cable is damaged. Impact and
heavy vibrations during transportation should be avoided.
Even if the switch casing remains undamaged, inside parts may be damaged and cause
malfunctions.
Electrical connection depends on the type of pressure switch (see type label) according to the chart
below.
Wrong assignment of the connections may cause malfunctions or incorrect switch outputs.

8 Operation
The switch may be installed and operated only by authorized persons. Do not use any hard objects for
making entries.
In case of first commissioning a self-test is performed. The device is menu-operated via three
membrane keys, which must not be touched with any hard objects.
If an error is detected during the self-test or normal operation, this error is signaled by a (yellow) flashing
alarm LED (AL). The error can be read out in the menu ERRC .
The green LEDs S1 and S2 signal the activity of the two switching points.
