How to teach-in the number of Flexi Loop nodes in the MSTR Flexi Loop accessory on:
b
Switch off both the Flexi Loop voltage supply and the IO-Link controller voltage
supply.
b
Remove wiring on the output X1 and wire the output X2 to the connections FC_A1
and FC_B1.
b
Switch on power supply.
✓
The configuration is saved, the operating mode LED flashes red/green alternately.
✓
Once the configuration has been saved the operating mode LED flashes green
(1 Hz).
b
Switch off the power supply.
b
Re-wire output X1 to the connection FC_A1 and output X2 only to connection
FC_B1 wiring.
b
Switch on power supply.
✓
The Flexi Loop string starts to operate, from this point on the MSTR Flexi Loop
accessory checks whether the correct number of Flexi Loop nodes are connected
on each power up.
To teach in a new configuration, carry out a new teach-in operation. This will irrevocably
overwrite the existing configuration.
If you want to delete a configuration, then undertake a new teach-in process without a
terminator. On the conclusion of the teach-in process the operating mode LED flashes
red at 1 Hz (configuration required).
Removing protection against tampering
DANGER
Hazard due to disabling the protection against tampering!
If you disable the protection against tampering, then a Flexi Loop node can be removed
or jumpered. In this situation the safe sensor cascade switches on despite the change.
Only disable the tamper protection if imperative for the implementation of the applica‐
tion. In this case prevent possible tampering by other measures (e.g. protected cable
laying).
