Operation see .
3.1.6 Function of the Buttons
Automatic end position programming and manual mode are generally activated
using the buttons in the cap. For safety reasons, the buttons are only enabled
within a specific time window after activation of the operating voltage. During this
time window, functions can be started. The buttons are automatically locked
again after the allowed time has expired.
During automatic end position programming, the control top autonomously
detects the number of solenoid valves fitted in the control top and carries out the
required programming steps fully automatically.
After end position programming the following is also possible:
•
Changing the tolerance ranges manually,
• factory setting to set the attenuation of feedback signals to inactive,
• activating the LEFF function on double-seat valves with lifting actuator.
It is also possible to change the colours for visualizing the end positions using the
"colour variant" function, which also results in the outputs for the feedback signals
being switched.
