Safety requirements
This unit has been designed and tested by the safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advises given in this manual will be adhered to when using the unit.
-
Trouble-free operation and reliability of the unit can only be guaranteed if the unit is not subjected to any other climatic conditions than those stated under “Specification”.
-
If the unit is transported from a cold to a warm environment condensation may fail the unit. In such a case make sure the unit temperature has adjusted to the ambient temperature before trying a new start-up.
-
If unit is to be connected to other devices (e.g. via serial interface) the circuitry has to be designed most carefully. Internal connection in third party units (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying the unit or another device connected.
-
If there is a risk whatsoever involved in running it, the unit has to be switched off immediately and to be marked accordingly to avoid re-starting.
Operator safety may be at risk if:- there is visible damage to the unit
- the unit is not working as specified
- the unit has been stored under unsuitable conditions for a longer time.
In case of doubt, please return unit to the manufacturer for repair and/or maintenance.
How to operate and maintain device
-
a.) Treat sensor carefully. Use only by above specification. (do not throw, hit against etc.).
Protect plug from soiling. -
b.) To disconnect pressure sensor do not pull at the cable but at the plug (to open lock).
When connecting the sensor make sure that arrows are pointing upwards and that plug is entered into device socket centrally.
Do not twist plug when entering socket.
If plug is entered correctly, it will slide in smoothly.
If plug is twisted or entered incorrectly the connecting pins of the plug can be spoilt by bending or broken . => Plug can no longer be used and connecting cable needs to be replaced. -
c.) Caution:
The pressure compensation hole of the relative pressure sensors has to be kept clean! It is placed at the back part of the housing. Do not cover with stickes or similar things!
Disposal instruction:
The device must not be disposed in the unsorted municipal waste! Send the
device directly to us (sufficiently stamped), if it should be disposed. We
will dispose the device appropriate and environmentally sound.
