•Insufficient control of parts subject to wear.

•Improper repairs of unqualified workers.

•Disaster situations caused by third parties or force majeure.



Disclaimer / Right of Amendment

This user manual is kept up to date. As the TRsystems Gmb / UNIDOR products

are subject to continual development technical modifications might lead to temporary

deviations between the device design and the user manual. Please note that

TRsystems Gmb is not liable for damages caused as a result of these deviations.

Due Diligence of the Operator

The LVCpro-S was designed and constructed followinga risk analysis and upon

careful selection of the relevant standards to be complied with, as well as other

technical specifications. It is state-of-the-art and ensures the maximum possible

safety during operation.

However, the machine safety can only be implemented if all necessary measures

have been taken. The planning of these measures as well as the control of their

implementation is part of the due diligence of the operator.

The operator must ensure that ...

•the machine is used in accordance with its intended purpose.

•necessary personal protective equipment for the operation, maintenance and

repair is available and used.

•

the machine is only operated, serviced and repaired by qualified personnel.

Product Specification / User Manual

Load Amplifier Cassette LVCpro-S

Furthermore the operator is responsible for ensuring that...

•this personnel is regularly trained in all relevant matters of occupational safety

and environmental protection and knows the the contents of the user manual and

especially the safety regulations therein.

•All safety and warning symbols attached to the machine must remain thereon

and be clearly legible.

Only use the device:

•forthe intended purpose in safe conditions.

•interferences which impair the safety of the device, must be removed

immediately.

•in an ambient temperature not exceeding a temperature range of to 45°C.



Intended use

The device is exclusively intended for the control and measuring of the machines and

equipment provided for this purpose. Any additional or further use is deemed as not

being in accordance with the intended purpose. The company TRsystems /

UNIDOR is not liable for damages caused following other usage.

Intended use also means:

•only using the device in immaculate condition.

•removing interferences which impair the safety of the device immediately!

•the risk ofinterference and damages of the device and the consequences caused

by its peripheral devices is generally subject to the user.

•ensuring prior to the start-up of the device that nobody can impair the starting of

the device. In case of malfunctions the device must be stopped and secured

immediately.

•

the monitoring of all control displays.



Obligations of the operator

•According to the electrical regulations, works on the electrical equipment shall

only be implemented by skilled electricians.

•The safety-conscious work of the personnel will be monitored periodically. The

user manual must be kept at all times ready to hand in close proximity of the

machine/device.

•Modifications by the client or third parties require the written confirmation of the

manufacturer. If a failure to observe leads to defects or malfunctions, the

supplier and manufacturer will be excluded of the guarantee and liability.

Product Specification / User Manual

Load Amplifier Cassette LVCpro-S

•Guarantee and liability will also be void if defects of the device are not

immediately notified to the supplier and appropriate measures for the damage

control were implemented to late or not at all. Spare parts must correspond to

the technical requirements defined by the manufacturer. Unauthorised

modifications to the program and the control system are not allowed. The

location and operation of extinguishers must be announced. The fire fighting

measures and reporting possibilities must be adhered! Extinguishers must be

suitable for the fire fighting of electrical fires.



Safety Instructions for Maintenance and Servicing

•The equipments always must be isolated from the power supply when

implementing maintenance, servicing or repairs.

•After completion of the work the functionality of the safety equipment must be

checked.

•The relevant safety and accident prevention regulations apply for the

corresponding situations.

•For 24VDC power supplies a safe, electric isolation of the low voltage is

important. Only use power supplies designed acc. to IEC 364-4-41 respectively

HD 384. 4.41 (VDE 1 part 41 ).

•Fluctuations or deviations of the mains voltage to the nominal value must not

exceed the tolerance limits defined in the technical specification, as this might

lead to malfunctions and hazardous conditions of the electric components.

•Connection and signal lines shall be installed in a way that inductive and

capacitive interferences (disturbances, e.g. unshielded valves on the machines)

do not impair the automation feature.

•Wiring as well as the opening and closing of electronic connections shall

only be implemented on isolated machines!

•Short-circuits, voltage peaks, etc. can lead to malfunctions and uncontrolled

conditions of the equipment and hence to severe personal and material damages.

•Check all the electric connections prior to the starting of the device!

•Incorrect connections can cause malfunctions of the device, faulty connections

can cause severe personal and material damages.

•Do not replace components under voltage and do not open enclosures

under voltage!

•Mechanical and/or electric modifications on our equipment are not permitted for

security reasons!

General Fault Clearance Measures / Shielding

•The use of electronic sensor active systems in modern equipment requires a

consistent and correctly implemented fault clearance and wiring concept. The

compliance with these requirements is important to ensure the proper function of

a device with electronic measuring systems.

•Access lines must be laid for remote control and must be separated from supply

lines stressed with disturbances (shielded).

•Ensure a continuous wiring of the shield as well as an extensive contact between

the shield and the electric terminals.

•Cable crossings must be avoided. If inevitable exclusively square crossings shall

be used.

9. Commissioning of the LVCpro-S

Wiring of the piezo sensors. Wire the measuring window and the outputs according to

the PIN-assignment. Apply supply voltage (it is important to use the correct polarity!)

Alignment (calibration) of the amplifiers with the piezo sensors used acc. to the table

in chapter 6.

For the code-switches SW2 1 (channel 1) or SW4 1 (channel 2) it is possible to

adjust different sensitivities of the sensors against the basic adjustments, when

working in a multichannel version of the measurement.

Adjustment of the amplification factor acc. to chapter 9 with the relevant code-

Product Specification / User Manual

Load Amplifier Cassette LVCpro-S

switches

SW2 2

(

channel

1) or

SW4 2

(

channel

2)

on the basic position

3

.

Adjust the maximum output of the measurement object (e.g. the maximum press

force). Continuously up-shift the code-switch SW2 1 (channel 1) respectively SW4 1

(channel 2) until reaching the desired output voltage on the analogous output (max.

1 V). We recommend a final adjustment of 7V output voltage for maximum load to

still enable an assessment in case of an overload.

If replacing the load amplifier cassette LVCpro-S it is important to maintain the same

adjustment of the code-switches, otherwise there is the risk of overload (falsification

of the measuring results)!
