Description of the function
• The sensor measures the upper edge of the valve spindle
• Non-contact and wear-free detection of the valve positions: closed,
open and the position for seat lift during the cleaning process
• It is also possible to monitor the state of the valve seals instead
of the seat lift. Due to the high resolution of 0.2mm even slight
changes can be detected
• Easy and time-saving adjustment by means of "teaching" (reading)
the valve positions. The "taught" valve positions are automatically
assigned certain switching characteristics of the three outputs, sev-
eral operating modes are available (see chapters Programming and
Set-up)
• Monitored stroke (detection range) 80mm. The condition "valve
spindle outside detection range" is indicated
• After adjustment the unit can be electronically locked to prevent
unauthorised manipulation
Application example
* The valve positions open and closed may also be reversed.
