Danger
Notice
CONNECTION INFORMATION & SAFETY INSTRUCTIONS
The guarantee will lapse in case of damage caused by failure
to comply with these operating instructions! We shall not be
liable for any consequent loss! We do not accept liability for
personal injury or damage to property caused by inadequate
handling or non-observance of the safety instructions! The
guarantee will lapse in such cases.
This manual contains additional safety instructions in the
functional description. Please note them!
If you notice any damage, the product may not be connected
to mains voltage! Danger of Life!
A riskless operation is impossible if:
• The device has visible damages or doesn't work
• After a long-time storage under unfavourable conditions
• The device is strongly draggled or wet
• After inadequate shipping conditions
• Never use this product in equipment or systems that are
intended to be used under such circumstances that may
affect human life. For applications requiring extremely
high reliability, please contact the manufacturer first.
•
The product may only be used for the applications
described on page 1.
• Electrical installation and putting into service must be
done from qualified personnel.
•
During installation and wiring never work when the
electricity is not cut-off ! Danger of electric shock!
•
To prevent electrical shock, the device may only be
operated in a closed control cabinet or control box.
•
Never operate unit without housing.
Danger of electric shock!
•
All ‘PE’ terminals must be connected to PE.
Danger of electric shock!
Additionally, the internal noise
filter will not work, faulty indicated values may occur.
• Please note the safety instructions and standards of your
place of installation!
• Before installation: Check the limits of the controller and
the application (see tech. data). Check amongst others:
- Make sure that all wiring has been made in accordance
with the wiring diagram in this manual.
- Supply voltage (is printed on the type label).
- Environmental limits for temperature/humidity.
- Maximum admitted current rate for the relays. Compare
it with the peak start-up currents of the controlled loads
(motors, heaters,etc.).
Outside these limits malfunction or damages may occur.
• Sensor/probe cables must be shielded. Don’t install them
in parallel to high-current cables. Shielding must be
connected to PE at the end close to the controller.
If not, inductive interferences may occur.
• Please note for elongation: The wire gauge is not critical,
but should have 0,5mm² as a minimum.
• Mounting the controller close to power relays is
unfavourable. Strong electro-magnetic interference,
malfunction may occur!
• Take care that the wiring of interface lines meets the
necessary requirements.
• All used temperature sensors must be identical. Never
use different types at the same time. This will not work.
• TF-type sensors are not designed for being immersed in
fluids permanently. In such a case, always use dip-fittings.
With extreme temperature variations, the sensor may be
damaged.
Cleaning
The use of a dry, lint-free cloth and household agents is
sufficient to clean the product.
Never use acids or acidic fluids! Risk of damage!
