4.5 Operation
4.5.1 Supply Voltage
Warning!
• When operating a system with the Mobile Panel, take note that at this point in
time operation is only possible using the Mobile Panel and is not possible
from any other point in the system.
• If the safety equipment (safety door, etc.) is not active, the movements carried
out using the Mobile Panel are only permitted when the enable switch is
activated and at reduced speed.
Danger!
When using an E-stop circuit according to EN 954-1, the function of the E-stop
circuit must be checked at least monthly.
Caution!
• The 24 VDC supply must be separated from the low voltage signals in a
secure manner to provide protection from dangerous voltages. This can be
done, for example, using a safety transformer or similar equipment.
• When dimensioning the supply, the voltage drop on the Mobile Panel
connection cable and switching cabinet cable must be taken into
consideration.
• The supply circuit must be protected using a 3 A (slow-blow) fuse.
Warning!
• The project engineer for a machine or system must make provisions to
guarantee that an interrupted program is started again properly after voltage
drops and power failures. Not even short-term operating states that cause
dangerous situations are permitted to occur.
• Errors that occur on automation systems can cause injury and damage to
material, therefore additional measures must be taken to ensure safe
operation of the entire system should errors occur.
• The functionality of the safety-relevant equipment (e.g. E-stop and enable
switch) must be monitored cyclically.
• After heavy loads, e.g. shock to the device or dropping the device, the safety-
relevant equipment must be checked.
