The ThinkTT
TT
Topop
opop
op®is designed to ensure optimum valve control in conjunction with Alfa Laval valves and it is compatible with most
PLC systems (Programmable Logic Controllers maker with PNP/NPN interface).
The ThinkTT
TT
Topop
opop
op®can be equipped with 0-3 solenoid valves. The solenoids are electrically controlled by the Digital PLC and when
activated the compressed air is activating the air actuator. All solenoids have built-in throttle function on both air inlet and outlet
which means that it is possible to control the opening and closing time of the air actuator. The solenoids are also equipped with
amanual holdoverride.
Visual LEDlightsareconstantlyindicating thestatusof theunit:Valvepositions,solenoid activated,setupand localfaultindication
etc.
The ThinkTT
TT
Topop
opop
op®is characterized by a simple and modular design. It is exchangeable and is prepared for upgrading.

3.1.1 “No Touch” sensor system
Type: Alfa Laval “No Touch” System
Forwire connections:See section4.4 “Electrical connection, internal”.
Features
Tolerance programmes.
Self adjustment programme (SRC/ARC valves only).
Built-inmaintenance monitor.
Setup by internal pushbuttons or remote control (IR Keypad).
Setup and local fault supervision.
Setup saved at power shutdown.
VisualLED Indicator lights.
Sensor System
Unique“No Touch”sensor system without any mechanicalsensor adjustments. A magnet ismounted on the valve stemand the
magnetic field (axial) is detected bysensor chips inside the sensorunit. The measuring angle fromeach chip is used tolocate the
current position of the valve stem with an accuracy of ± 0.1mm. Note that the distance to the magnet can be 5 mm ± 3 mm.
Feedback signals
Thesensor system can beused for 4 feedbacksignals + 1 status signal= 5 digital PNP/NPNfeedback signals. Selection ofPNP
or NPN is done by a jumper. Two of the feedback signals can be used for external sensors if necessary.
The status signal is used for detection of the following three conditions:
• A set-up is in progress.
• Internal error.
• Maintenance is required (based on time and/or the self adjustment programme).
Tolerance programme:
Individual according to valve types.
• Type 1: SRC/ARC and Series 700 valves.
• Type 2: LKB(LKLA-T).
• Type 3: Unique, SMP-SC Spillage-Free, SRC-PV and AMP.
• Type 4: SMP-SC, SMP-TO, SMP-BC, SMP-BCA and SBV.
• Type 0: (Preset) All Parameters Set To Default (also valid for MH Koltek valve and SMP-EC
(seat-lift indication not possible for SMP-EC)).
Preset and reset values: Tolerance programme No. 0 (± 5mm) and all functions are disabled.

3. Technical specifications 3.1 ThinkTop®, PLC 8-30 VDC interface
Self Adjustment (SRC/ARC valves only)
The self adjustment feature is an exceptional aspect of the ThinkTop®design. A programme can be activated to allow an
adjustmentof the tolerance band ifthe seals in the valveare being compressed or areworn. When the tolerance band of the unit
hasbeen adjusted0.3mm, analert warningwill appearin theform ofa statussignal anda flashingmaintenanceLED. After0.5 mm
adjustmentan alarm warningappears: Loss of feedbacksignal, status signaland steady maintenance lightindicating a minimum
of seal left requiring a replacement of the seal.
Built-in Maintenance Monitor
The unit can be preset to indicate when the time for maintenance of the valve has been reached. A status signal and flashing
maintenance LED can be programmed to return after 3, 6, 9 or 12 months or more.
3.1.2 Technical specifications sensor system
Sensoraccuracy: ± 0,1 mm.
Distance to magnet: 5 ± 3 mm.
Stroke length: 0.1 - 80 mm.
Electricalconnection: Direct cable gland entry (hard wired)
PG11 (ø4 - ø10 mm).
Terminals
The terminal row of the sensor unit is equipped with screw terminals for both internal as well as external cables and wires. The
terminals are suitable for wires up to 0.75 mm2 (AWG 19).
Power Supply, must meet the requirements of EN 61131-2.
The ThinkTop®is designed to be a part of the PLC's Input/Output (I/O) system. It should be supplied from the same protected
power supply as the other I/O devices. The I/O power supply should not be used for other kinds of loads.
The unit is reverse polarity and short circuit protected.
Supply voltage: 8 - 30 VDC.
Supply voltage nominal: 24 VDC (+20%, -15%) - pr. EN 61131-2.
Maxripple: 5% of nominal supply voltage.
Supply voltage absolute max.: 30VDC.
Supply voltage absolute min.: 8VDC.
Supply current*): Max. 45 mA (for sensor unit alone)
(excludingcurrent to the solenoids,external proximity switches and the PLC inputcurrent).
*) The initial current during power-on is higher. The actual shape of the current pulse depends on the power supply used. Typical
values are 150 mA RMS during 13 ms (regulated PS) to 360 mA RMS during 8 ms (unregulated PS).
The fulfilling of the UL requirements in UL508 requires that the unit is supplied by an isolating source complying with the
requirements for class 2 power units (UL1310) or class 2 and 3 transformers (UL1585).
Feedback signals
Output signals from the sensor unit to the connected PLC.
Nominalvoltage: Must match the selected type of ThinkTop®.
Loadcurrent: Typically 50 mA, max. 100 mA .
Voltage drop: Typically 3 V at 50 mA.
External sensors
The external sensors are used for seat-lift supervision when seat-lift can not be internally detected. The sensors get their supply
voltagefrom the terminalrow.Theoutput signals fromthesensors areconnected to two inputson the terminalrow onthe internal
sensorunit. Ifthe actualsetup isset forinternal seat-lift, the corresponding externalsignal isnot used,otherwise theexternal signal
logically controls the corresponding feedback to the PLC (Programmable Logic Controller).
Supply voltage: Must match the selected type of ThinkTop®.
Supply current: Max. 15 mA per sensor.
Type of sensor: DC, Only 3-wire sensor PNP.
Sensorcable length: Max. 3 m.
Polarity
PNP (sourcing) or NPN (sinking) function is selected with a jumper in term. 12 and 13.
Jumper present = PNP. If changing to NPN remove the jumper and make a power recycle. A power recycle is always required
whenchanging thisfunction.

Note: If the programmer wishes to detect a physical closed valve position in an "Open Valve" sensor position, then there is no
longer any consistence between the sensor valve detection position and the visual indications of the ThinkTop®.
Status signal:
The status signal (Feedback # 5) is used for four purposes:
• To indicate that setup is in progress + (LED D).
• To indicate an error condition + (LED D). (Flashing LED = software error), (steady LED = hardware error).
• To indicate maintenance due to the self adjustment programme + (LED F).
• To indicate that the time for maintenance has been reached + (LED F).
3.1.3 Technical specifications solenoid valves
Solenoid signals
Three output signals (with one common) from the terminal row are used for activation of the solenoids. Depending on the PLC
used, the common could be either positive or negative for DC voltage. The signals are galvanically isolated from the sensor
circuits.
Internal connections
Terminals forconnection of thesolenoids mounted internally in thecontrolhead. Thenumber of solenoidsactually mounted inthe
control head could be 0 - 3. The signals are taken directly from the terminal row.
