INSTALLATION
To obtain the best results it is recommended to install the indicator and the platform (or transducer) in a place
with the following conditions:
A flat, level surface on which to rest
Stable and vibration free
Moderate temperature and humidity (15-30°C and 40-70%).
No dust or strong vapours
No draughts
Mains power supply is restricted to 12…. 24Vdc
Make sure the platform is level or that the loading cells are resting evenly
Avoid welding with load cells installed.
When the load cells are used with assembling kits under storage bins or the like, connect the upper
and lower supporting plate with a copper wire cable and then earth all the upper plates.
Use waterproof sheaths and couplings in order to protect the load cell cables.
Use a waterproof junction box to connect the cells.
The extension leads of the load cells or signal amplifiers must be screened. In addition they must be
laid on their own in a raceway or metal pipe as far away as possible from the power supply cables.
Connection of the cell or amplifier cables on the electrical panel shall be independent and, if possible,
connected directly to the indicator’s terminal board without laying other cables in the raceway.
Install “RC” filters on the contactor coils, on the solenoid valves and on all devices producing electric
disturbances.
If it is possible that condensation could form inside the weight transmitter it is advisable to leave the
instrument powered at all times.
Electric protections (fuses etc.) are provided by the technician installing the instrument.
Do not install anywhere where there is the risk of explosion.
All cables must be wound at least once around the ferrite ring before being connected to the terminal
board; the cable screen must be left outside of the ferrite and should be connected to the relevant
ground pin.
