I I The following applies to all setting procedures:
• If no button is pressed for 15 s during the setting procedure, the
unit returns to the operating mode with the parameter values
unchanged.
• If adjustment has not been possible, all the red LEDs flash. The unit
returns to the operating mode with the parameter values
unchanged.
I I Locking / Unlocking
The unit can be electronically locked to prevent unwanted adjustment
of the set parameters: Press both setting buttons for 10 s (the unit
must be in Run mode). Indication goes out briefly (acknowledgement
of locking / unlocking).
Units are delivered from the factory in the unlocked state.
If the unit is locked, it is possible to indicate
• the current switch point 1 (press the Mode/Enter button once),
• the current switch point 2 (press the Mode/Enter button two times),
• the setting of the function "monitoring excess flow" (press the
Mode/Enter button three times).
Installation and set-up / Operation / Maintenance
After mounting, wiring and setting check whether the unit operates
correctly.
When the supply voltage is applied, all LEDs light and go off one after
the other.* The unit is then ready for operation.
*During this time both outputs are switched according to the programming:
ON with the NO function and OFF with the NC function.
Failure indication:
5 left LED's flashing in case of short-circuit at the output S1; 5 right
LED's flashing in case of short-circuit at the output S2.
Recommended maintenance
Check the sensor tip for build-up from time to time. Clean it with a
soft cloth. If necessary, build-up which adheres firmly (e.g. lime) can
be removed with a common vinegar cleansing agent.
