Safety requirements:
This device has been designed and tested in accordance with 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 device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other climatic
conditions than those stated under "Specification".
2. If the device is transported from a cold to a warm environment condensation may result in a failure of the unit. In such a case
make sure the device temperature has adjusted to the ambient temperature before trying a new start-up.
3. If device 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 devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying
the device or another device connected.
4. If there is a risk whatsoever involved in running it, the device 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 device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
How to operate and maintain unit:
a.) Treat sensor carefully. Use only in accordance with 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.) Connection diagram for sensor tube connection:
For measurements of over pressure (relative pressure sensor):
- Connect plastic tube with internal dia of 4 mm to cable gland "B". Connection "A" will not be used!
For measurements of pressure differences (relative pressure sensor):
- Connect both plastic tubes with an internal dia of 4 mm to cable gland "B" and "A"; make sure to apply higher pressure to
connection "B".
For measurements of absolute pressure (absolute pressure sensor):
- Connect plastic tube with an internal dia of 4 mm to cable gland "A". (Cable gland "B" is not used.)
