This connection is established inside the conXion units but can be removed with a jumper. Please refer to the installation manual for further details.The numbers in the (parentheses) refer to the Molex Minifit layout.Please find further information on jumper settings for the conXion Box, Box+ and DIN versions in the conXion - Installation Guide:https:///information/downloads/#manualAll icon actuators come with an 8-pin Molex Mini fit JR connector unless specified otherwise and the connections for each configuration are shown in the table below.U S E R M A N U A L | icon | March 2022 | 3i c onUS ER M A N U A L4 | U S E R M A N U A L | icon | March 2022i c o nCAS can be downloaded free of charge from the Concens website:https:///information/downloads/#softwareConcens Actuator Studio (CAS)T o connect the icon actuator to CAS, we recommend using the Concens programming cable as shown below in conjunction with the conXion box, box+ or DIN.Programming cable CC-874-01-0000-00-00conXion BoxCC-971-07-0000-00-00conXion DINCC-971-06-0000-00-00conXion Box+CC-971-05-0000-00-00When CAS is started, it initially shows a window with information about version etc. This window closes automaticallyafter 10 seconds or can be closed manually after which the overview screen appears.The number of icons connected can be adjusted, and the number of lines shown in the overview window will change accordingly. Only one icon at a time can be active and operated in CAS. However, it is possible to see all actuators in the overview. If an actuator is recognized the uptime counter will be counting if “Active” is ticked.When more icons are connected, they must have different addresses. All single setup icons come with default address 8. This can be changed under the “Service/Config” tab. Enter new address in “Modbus address” and click “Save/Update”.Address range for single actuators is 1 to 199. Multi setup icons (MDO) are preset to addresses from 200 to 207 with 200 being “Master” (please refer to MDO section).U S E R M A N U A L | icon | March 2022 | 5i c onU S E R M A N U A L6| U S E R M A N U A L | icon | March 2022i c o nreturns the piston to the fully retracted position and stores this position as “Home” (Position 0). The Learn function runs a full cycle and determines both fully retracted and fully extracted positions of the piston. Please note that these positions may be determined by physical limitations in the mechanical design of the application and not by the end positions of the actuator.Before performing a "Home" or "Learn" cycle the actuator(s) need to be pinned or installed in both the rear and front bracket. Otherwise the piston can spin and give an incorrect result.Click the “Run Learn” under the “Service/Config” tab to perform a learn cycle. If required by the application, “Home” position can be changed to fully extracted position and, speed during learn can be adjusted. All actuators in a multi-actuator setup must be “Homed” individually.If pin 5 and pin 6 are connected to GND simultaneously for more than 10 seconds, Homing/Learning is started. During this the actuator will travel at a lower speed and it is important that neither of the brackets can rotate freely. 0-point - (Homing) and maximum stroke length (Learning) are saved during this cycle.Please note: Learn will reset settings for “Range Scale”.Performing a Learning without having access to the CAS software can be done by using either the handset or conXion Box+ by pressing and holding both in and out buttons for 10 seconds.Depending on the original setting of the “actuator homeposition” the end position will either be Retracted or Extracted after performing the Learning process.Safe zones can equally be set without having access to the CAS software by using the handset or conXion Box+. Setting the safe zone out is done by pressing both buttons for 5 seconds and then pressing out button.Setting the safe zone in is done by pressing both buttons for 5 seconds and then pressing in button.Other basic parameters that can be adjusted under the “Actuator/Parameters” tab.As a part of a learn cycle, “Safe Zone” values are default set to 50 steps (Backwards) and full stroke-50 steps (Forward). If the stroke length is entered manually, it is necessary also to enter Safe Zone values.U S E R M A N U A L | icon | March 2022 | 7i c onU S E R MA N UAL8 | U S E R M A N U A L | icon | March 2022i c o nBlock diagramA block diagram for the icon SDB configuration is shown below:12/24TX +A RX -BIconBlock Diagram SDBnot used.Signal GND (orange)is connected to GND (black)inside the iconPin numbers refer to Molex 8-pin connector.

Pin 5 and pin 6 are active low and must by pulled down to power GND to activate. The hall channels at pin 3 and pin 7 are 3.3 Vpp square wave signal (max 5mA) with a 50% duty cycle and a 90˚ phase shift. Hall outputs are NPN logic TTL level.If pin 5 and pin 6 are connected to GND simultaneously for more than 10 seconds, Homing/Learning is started. During this the actuator will travel at a lower speed and it is important that neither of the brackets can rotate freely. 0-point - (Homing) and maximum stroke length (Learning) are saved during this cycle.Special function for SDH is hall output at pin 3 (hall A) and pin 7 (hall B)Interconnection/Modbus controlThe icon SDH can also be controlled by Modbus but with the same limitations as already mentioned. Y ou can add numerous SDH icons to your application if each is provided with an individual address. If controlled with Modbus it is still possible to override with an analogue input from the handset or contacts.

The inputs for direction at pin 5 and pin 6 are active low and must by pulled to power GND to activate. Pin 7 is an analog output that relate to the actual position of the piston. The output has two ranges, which can be selected in CAS: 0-5 VDC and 0-10 VDC for 24 VDC icons, but only 0-5 V range for 12 VDC icons. Power GND and Signal GND must be connected at the PLC or at the end of the cable. If pin 5 and pin 6 are connected to GND simultaneously for more than 10 seconds, Homing/Learning is started. During this the actuator will travel at a lower speed and it is important that neither of the brackets can rotate freely. 0-point - (Homing) and maximum stroke length (Learning) are saved during this cycle.

Please refer to the conXion Box/Box+/DIN documentation for further details.Modbus control is not recommended with the SPP configuration as the analogue input always has higher priority than Modbus commands.Block diagramA block diagram for the SPP configuration is shown below:12/24TX +A RX -BIcon Block Diagram SPPPosition is reference (0-5(10)V).Blue wire is position input.Yellow wire is signal GND.Please Note:White, Brown, Blue and Orange wire have different functionality according to configuration.See Data sheet for more information.The icon SPP has an analog input for positioning at pin 5 and a reference output at pin 7. Reference voltage is selectable via CAS, i.e. 5 or 10 VDC (5 VDC only for 12 VDC actuators). Pin 6 has combined purpose for “Position OK”, “STOP”, and “Home/Learn”. Under normal conditions pin 6 is “high” (3.3 VDC/max 5mA) when the actuator is moving. When the target position is reached it signals “Position OK” by switching to 0 V (low) and the actuator stops. In addition to this, pin 6 can also be used as an input by pulling it down to GND. This will stop the actuator. If pin 6 isconnected to pin 5 during power up the Homing/Learning cycle is activated.i c oni c o nBlock diagramA block diagram for the SBS configuration is shown below:12/24Icon Block Diagram SBScase an error is detectedand if pulled to ground anymovement is disabledPlease Note:White, Brown, Blue and Orange wire have different functionality according to configuration.See Data sheet for more information.Pin 5 (active low) is a digital stop input, which disables the motor drivers in the icon completely. Pin 6 (active high) is a fault output. Any fault detected is indicated by a change from 0 VDC to 3.3 VDC at this pin. Pin 3 is a signal GND connection.The conXion Box/Box+/DIN can be used as an interface. Please refer to the conXion Box/Box+/DIN documentation for further details.Interconnection/Modbus controlThe interconnection of icon SBS is illustrated below.

All other parameters in the icons must be identical. This is configured from factory but can be changed via CAS.Please refer to the Basic Operation section to perform Homing of the actuators and please note that all actuators in an MDO setup must be Homed individually.Pin 5 and pin 6 of the master icon are used to control the actuators out and in respectively. Both pins are active low, i.e. they need to be pulled down to GND to activate.Pin 7 is an override input (active low), which enables individual travel (adjustment) of one actuator in the setup. After activating pin 7, pin 5 and pin 6 on the specific actuator can be used to move the piston.InterconnectionThe figure below shows an MDO setup with conXion DIN units connected to a PLC using the Direction Out and Direction In pins on the master actuator.

You can store the values in the memory. Measurements that are done in the other modes cannot be stored in the memory!Measuring Protective Conductor resistanceDefinitionProtective conductor resistance is the sum of the following resistances:• Connector cable or device connector cable resistance• Contact resistance at plug and terminal connections• Extension cable resistance if utilizedResistance is measured:• Between each conductive part of the housing and the earthing contacts at the mains and the device plug (if a removable mains connector cable is used), or the protective conductor terminal for permanently installed devices.• as 4-pole measurement• Between the earthing contacts at the mains plug and the earthing contacts at the device plug for device connector cables• Between the earthing contacts at the mains plug and the earthing contacts at the coupling socket for extension cablesConnecting Safety Class I Devices to the Test SocketWhen the DUT is connected, resistance is measured between the protective conductor terminal at the test socket or at the PE jack and the probe connection at the DUT (contact with conductive parts of the housing).In order to measure protective conductor resistance, contact a conductive part of the housing with the probe, which isconnected to the protective conductor.During measurement, the connector cable must only be moved in as far as it is accessible during repair, modification or testing. If a change in resistance occurs during the manual test step of the continuity test, it must be assumed that the protective conductor is damaged, or that one of the connector contacts is no longer in flawless condition.Pay attention on the type of the DUT to define the limit of the measured values!Connection DUT with the SECU LIFE ST and connection with the probeIsolation MeasurementIsolation Resistance RINSDefinitionSafety Class IIsolation resistance is measured between short-circuited mains terminals and the protective conductor.Safety Classes I I and I I IIsolation resistance is measured between short-circuited mains terminals and external conductive parts which can be contacted with the probe.SequenceCurrent is displayed during this type of equivalent leakage current measurement which would flow during leakage current measurement conducted in accordance with device regulations with nominal voltage. Leakage current measurement in accordance with the respective device regulations is usually not possible, because the device would have to be set up in an electrically isolated fashion, or connected to an earth isolated power supply to this end.Equivalent Leakage Current IEL DIN VDE 0701-0702 / 2 K→Select the I-EL measurement and start.Equivalent leakage current is measured between short-circuited N and L, and the protective conductor PE. Measuring circuit resistance is equal to 2 kΩ for VDE 0701-0702 for the simulation of the mean body resistance of a human being.Equivalent Device Leakage Current IEDL for IEC 62353 (VDE 0751-1) / 1 K→Select the I-EDL measurement and startEquivalent device leakage current is measured between short-circuited N and L, and the probe. Measuring circuit resistance is equal to 1 k Ω for IEC 62353/VDE 0751 for the simulation of mean patient resistance.Equivalent Patient Leakage Current IEPL (IEC 62353 (VDE 0751-1))→Select the I-EPL measurement and startEquivalent patient leakage current is measured between short-circuited N and L and the respective application part. Jacks A through K (application parts) are connected separately for each application part. Groups of cables or sensors can be assigned to application parts in the test sequence start menu in accordance with IEC 62353 (VDE 0751-1) or EN 60601.Pay attention on the type of the DUT to define the limit of the measured values!B=Body, BF= Body Float, CF = Cardiac FloatConnection DUT with the SECU LIFE ST and connection on the DUT (in this case: infusion pump)Leakage Current MeasurementSelect the Ixx measurement and startEach time line voltage is applied to the test socket, L and N are reversed,Earth Leakage Current IPE (Feature KA01)Current which flows from the power pack over the insulation to the protective conductor, and thus to earth.Contact CurrentCurrent which flows from housing parts which are not connected to the protective conductor via an external conductive connection to earth or another part of the housing. Flow of current via the protective conductor is excluded in this case.The AC component is measured. The DC component can also be measured if individual measurement is performed (instead of a test sequence).EN 60 601/VDE 0751:The following sequence is programmed for measuring and documenting several exposed conductive parts:If the acoustic signal chain changes from long to short intervals, it means that measurement is completed and the next measuring point can be selected and scanned (key).Patient Leakage Current IPLCurrent which flows from an application part via the patient to earth. This current may be caused by an unintentional interference voltage at the patient, and may flow via the patient and an insulated, floating type F application part to earth. Useful patient current is excluded in both cases. AC and DC components are measured.Patient Auxiliary Current IPA (Feature KA01)Current which flows within the patient between the electrodes of the application part. Use for intended purpose is assumed. Furthermore, the current should not cause any physiological effects.For example, this is the case for input current from amplifiers, or current used for impedance plethysmography.AC and DC components are measured.Residual Current IRCSum of instantaneous current values which flow via the L and N conductors at the device mains connection (also known as differential current).Residual current is practically identical to fault current in the event of an error. Fault current: Current which is caused by an insulation defect, and which flows via the defective point.Device Leakage Current ILC per IEC 62353 (VDE 0751-1)Device leakage current is the sum of all leakage currents from the housing, all accessible conductive parts and all application parts to PE. Measurement must be performed for both mains polarities and the largest value is documented.Connection to the DUTMultimeter FunctionsProbe Voltage Uprobe– Max. 300 VVoltage is measured between the mains PE terminal at the test instrument and the probe. In this case the probe can also be used as a phase finder.For IEC 61 010: A selection can be made with the up scroll key as to whether testing will be conducted under normal conditions, or with interrupted protective conductor.For conducting the measurement the DUT must be put into service via key (14).Start the Uprobe measurement.Alternating / Direct Voltage UAC/DC– Max. 253 VDirect, alternating and pulsating voltages of up to 253 V can be measured between the 2 and 3 connector jacks.Furthermore, it is possible to switch between minimum, maximum and momentary measured value via key. This is particularly useful in combination with the SECULOAD test adapter for welding equipment (article number Z745).7。
