Dear customer, thank you for buying this PTM product.
We advise you to read this manual carefully
in order to use the product at best.
SAFETY AND MAINTAINANCE INFORMATION
Never open the protection box of the scale.
Should the scale be damaged, or should liquids have soave in, have the scale checked by a service point.
Never pull the cables in order to disconnect the scale, but unscrew the connectors in the right way.
If the device is provided with an electro-valve control box, remind that this is equipped with a fuse for
protection against power supply inversions and current overflowing. In case the fuse breaks down, replace it
with an equivalent one.
Do not lay the device cables (e.g. load cell cables, data transmission cables, cables to control relay boards,
etc.) near supply cables of other electric or electronic devices.
Supply the device with tensions consistent with the technical features of the product.
Have installation and maintenance work carried out by qualified staff.
Working on the electro-valve control box, by making connections or adjustments which are not authorized by
PTM, is prohibited.
Do not lay the cables which are connected to the scale near moving mechanical parts.
Once you have finished working with the device, we suggest you store it on its holder.
Before cleaning the machine with high-pressure water, protect the scale against possible water infiltrations.
We also remind you to be extremely careful and not expose electronics, cables and other optionals to direct
water jets.
It is possible to clean the scale outside by using a soft and damp cloth, avoiding solvent or abrasive
substances, sharp or cutting objects which can damage the device.
Do not expose the scale to temperatures higher than the limits indicated in the technical features.
In order to reach a longer duration, do not expose the scale directly to atmospheric events, such as rain,
snow, frost, etc.
Never unscrew the grounding clamp which can be found on the protection box of the scale.
Do not use sharp or cutting tools to press the keys.
In case of installation, maintenance and reparation of the scale or the load cells, carry out a weight check /
calibration before making the weighing system operating.
Should the scale be equipped with data saving through USB Pen Drive or Memory Card, insert the saving
device in the correct way.
Before carrying out installation, maintenance and reparation works on the scale or the load cells, disconnect
all the machines which could be connected to the weighing system.
Before carrying out installation, maintenance and reparation works on the system, disconnect the power
supply.
Should the scale be equipped with relay boards, never connect the board directly to electric engines, devices
with a higher tension than 110V, etc.
During the charge of the machine battery, disconnect the power supply cable from the scale.
Before carrying out welding on the machine, disconnect all the cables from the scale.
In case of welding on the machine, place the grounding clip near the welding point, in order to prevent
electric current from passing through the load cells.
In case of welding on the device/machine, disconnect the electro-valve control box and the electronic
equipment, by unplugging the power supply cable, all the electro-valve cables and the connection cable to
the handheld remote control.
We suggest NOT to use electro-valves which have the connection to the body of the electro-valve itself.
All responsibility for installation, maintenance and reparation works falls on the person who carried them out.
