Sensor S
ystem
Unique “No Touch” sensor system without any mechanical sensor adjustments. A magnet (indication pin) is mounted on the
valve stem and the magnetic field (axial) is detected by sensor chips inside the sensor board. The measuring angle from each
chip is
used to locate the current position of the valve stem with an accuracy of ± 0.1mm. Note that the distance to the
indication pin can be 5 mm ± 3 mm.
Feedb
ack signals
The sensor system can be used for 3 feedback signals + 1 status signal = 4 feedback signals. (One of the feedback signals can
be used for two external sensors if necessary).
The status signal is used for detection of the following conditions:
- A set-up is in progress.
- Internal error.
- Maintenance is required (based on time and/or the self adjustment programme).
Tolerance programme
Individual programme according to valve types.
Type 0: ...............................Bypass valve type / keep present valve type.
Type 1: ...............................SRC/ARCandSeries700valves, only whenself adjustment is enabled - Not recommended.
Type 2: ...............................LKB (LKLA-T).
Type 3: ...............................Unique Mixproof, SMP-SC Spillage-Free, and SRC-PV.
Type 4: ...............................SMP-SC, SMP-TO, SMP-BC, SMP-BCA, SBV, SRC, ARC, Unique SSV,
Unique SSV Aseptic, Unique-TO and Series 700 valves.
Type 5: ...............................All Parameters Set To Default (also valid for MH valve and SMP-EC
(seat-lift indication not possible for SMP-EC)).
Preset and reset values: Tolerance programme No./Type 5 (± 5mm) and all functions are disabled.
Note!
Important to select the right tolerance programme in order to ensure optimum controlled closeness of valves.
