2.6 PRODUCT- AND TECHNOLOGY-RELATED SAFETY
INSTRUCTIONS
WARNING
Hazardous movements!
Risk of injury due to incorrect connection or incorrect activation of the digital axis
control and resulting unforeseeable machine movements.
▶ Observe safety in accordance with EN 13849 or IEC 62061.
▶ If persons have to enter the hazard zone while the control is active, provide
superordinate monitoring functions or measures for personal safety. These
measures must be provided according to the specific data of the system and
on the basis of the risk and error analysis of the system manufacturer/user.
In this connection, the safety provisions applied for the system must be taken
into account.
▶ Failures and defects in the control current or the energy supply can result in
uncontrolled machine movements. Observe safety in accordance with EN ISO
13849 or IEC 62061.
▶ The electronics emits interference to other electronics within the permitted
limit values. This can cause malfunction in the control process. Only use
electronics below the EMC limit values or provide appropriate shielding.
▶ The electronics of the digital axis control VT-HMC...1X responds to
electromagnetic interference from non-shielded, improperly installed or
wrongly connected signal cables. If the limit values given in the data sheet are
exceeded, malfunction or uncontrolled movements are possible. Adhere to the
limit values given in the data sheet, use only electronics below the EMC limit
values or provide proper shielding.
▶ Electrostatic processes, an inadequate grounding concept or missing
equipotential bonding can lead to damage to the electronics and hence
cause malfunction or uncontrolled movements of the machine. Ensure proper
grounding and provide equipotential bonding.
▶ Using the product outside the specified IP protection class can result in
short-circuit and malfunction and hence in uncontrolled machine movements.
Therefore, use the product only within the IP protection class and in
environments as specified in the data sheet.
▶ Provide safety functions for personal safety separately. The digital axis control
VT-HMC...1X itself does not include safety functions for personal safety and is
no safety-related component.
High electrical voltage by incorrect connection!
Danger to life, risk of injury due to electric shock.
▶ When carrying out any work, disconnect the relevant machine section from the
power supply and protect it against being switched on again.
▶ Only connect devices, electrical components and cables which feature
protective extra low voltage (PELV) to connections or terminals having
voltages from 0 to 50 Volt.
▶ Only connect voltages and power circuits that feature safe isolation
from dangerous voltages. Safe isolation can be achieved with isolation
transformers, safe optocouplers or mains-free battery operation.
Lightning!
Risk of uncontrolled machine movements.
▶ An inadequate grounding concept or missing equipotential bonding can lead to
damage to the electronics. Provide for equipotential bonding of the device.
