item Value Function/Description
Only models with analog output:
* 0 ... xxx Scale the analog output - start value (e. g. 0 bar = 4 mA)
* 0 ... xxx Scale the analog output - end value (e. g. 400 bar = 20 mA)
(output signal start value always corresponds to the display initial value, e. g. 0
bar = 4mA)
Maximum turn-down 4 : 1, i.e. at values below 25 % of the measuring range
the analog output is switched off
0 ... xxx Display of peak value „Max“ (xxxx: = max. 125 % f. s.)
Delete the maximum value memory
= no deletion
= delete value
Error display:
= no error
= exceeding pos. measuring range
= exceeding neg. measuring range
= sensor error
= error switching output 1
= error switching output 2
= data error (EEProm)
= program error
= calibration error
= error analog out
IMPORTANT
When changing units from psi to bar or bar to psi, the switching point values must be changed
accordingly.
* Flashing of the mean segment signals a negative setting value.

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 media temperature 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 ranges must be within the permissible limits. The stated pressures and electrical
load values must not be exceeded.
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 PED 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 switch and/or to the plant.
IMPORTANT
Refers to important information essential to the user.
Disposal
The switch 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 hex 36 (1/4“) resp. 19 with
45 Nm torque.
Do not put the switch into operation when the switch itself or the connection cable is damaged.
Jolts and heavy vibrations must be avoided during transport. Even if the switch casing remains
undamaged, inside parts may be damaged and cause malfunctions.

8 Operation
The switch must be installed and operated only by authorized persons. Do not use any hard objects for
making entries. After being switched on the Switch 2000 / TempSwitch 2000 runs through a self-test.
Operation via three plastic film keys is menu-driven. These keys must not be touched with hard objects! If
an error is recognized during the self-test or during operation, this is signalled by the (yellow) flashing
alarm LED (AL).
The error can be read out in the menu . The green LEDs S1 and S2 signal the activity of the two
switching points.
