Leakage L > permitted value -L-
•
The area gripper immediately begins to correct
it
•
A condition monitoring warning is activated
•
The system status indicator light turns yellow
The specified value for the maximum permitted leakage -L- can be set in the EF menu with the parameter
or
via IO-Link [0x006C]. The maximum leakage that can be set is 999 mbar/second.
Monitoring the control threshold
If the switching point SP1 is never reached during the suction cycle, the “SP1 not reached” condition monitoring
warning is triggered and the system status light switches to yellow.
This warning is available at the end of the current suction phase and remains active until the next suction cycle.
Monitor Dynamic Pressure
If possible, a dynamic pressure measurement is taken at the start of every suction cycle (vacuum during unobstructed
suction). The result of this measurement is compared to the limit values set for SP1 and SP2.
If the dynamic pressure is greater than (SP2 – rP2) but less than SP1, the corresponding condition monitoring warning
is triggered and the status light switches to yellow.
Monitoring the Supply Voltages
The area gripper is not a voltage meter. However, the measured values and the system responses derived
from them provide a helpful diagnostics tool for condition monitoring.
The area gripper measures the supply voltages U
S
. The measured value can be read from the parameter data.
If the voltages are outside the valid range, the following status messages change:
•
Device status
•
Condition monitoring parameter
•
An IO-Link event is generated
