Warnings and Errors
52 / 72 EN-US · 30.30.01.01484 · 00 · 01/21
Any condition monitoring events that occur during the suction cycle cause the system status indicator
light to immediately switch from green to yellow/orange. The event that caused this switch can be seen in
the “Condition monitoring” IO-Link parameter.
The table below explains the coding of the condition monitoring warnings:
Bit Event Update
0 Valve protection function activated Cyclic
1 Set limit value t-1 for evacuation time exceeded Cyclic
2 Set leakage limit value -L- exceeded Cyclic
3 Limit value H1 was not reached Cyclic
4 Dynamic pressure > (H2 - h2) and < H1 As soon as a corresponding dy-
namic pressure value has been de-
termined
5 Supply voltage U
S
outside the operating range Constant
7 Input pressure outside operating range Constant
The four bits with the lowest values describe events that can only occur once per suction cycle. They are
reset at the start of every suction cycle and remain stable until after suctioning has finished.
Bit number 4, which describes dynamic overpressure, is initially deleted when the device is switched on
and is updated when a dynamic pressure value is detected.
Bits 5 and 7 are regularly updated independently of the suction cycle, and reflect the current values for
the supply voltage and system pressure.
The values measured by the condition monitoring system, namely the evacuation times t
0
and t
1
and the
leakage value L, are reset at the beginning of the suction process and updated once they have been mea-
sured.
12.3 System Status Light in IO-Link Mode
The overall status of the ejector system is displayed as a traffic light using 3 bits in process data input byte
0. All warnings and errors are taken into account when defining the status of the traffic lights.
This basic display provides immediate information about the status of the ejector with all its input and
output parameters.
System sta-
tus displayed Description of the status
Green System is working perfectly with optimal operating parameters
Yellow Warning – Condition monitoring warnings in place; ejector system not functioning per-
fectly
Check operating parameters
Red Error – Error code provided in parameter error; safe operation of the ejector within the
operating limits is no longer ensured
• Cease operation
• Check the system
