  • Page 8: Product Description

    The IQAN-MD4 module. System overview The master module, IQAN-MD4, is the central unit in the system, or in the case of a multi-master system, one of the central units. IQAN-MD4 has four CAN buses and two ethernet ports. The CAN buses support ICP and are able to control IQAN expansion units.

  • Page 9: I/O

    (2) Digital inputs DIN-I and DIN-J Digital inputs The IQAN-MD4 module has eight (8) digital inputs DIN-A thru DIN-H. DIN-A thru DIN-D are multi purpose and can be configured as low-side on/off outputs. DIN-G and DIN-H are multi purpose and can be configured as a directional pulse count input. see below.

  • Page 10: Communication

    IQAN-G11 or to a connected PC (requires compatible USB to CAN adapter). In the IQAN-MD4, the CAN channels are paired in groups of 2. There is CAN-A and CAN-B, where the CAN controllers are in the main processor, compared to CAN-C and CAN-D, that are controlled by the co-processor.
  • Page 11 The backlight is automatically dimmed at supply voltage <14V. Image persistance The IQAN-MD4 TFT LCD, like all other LCD screens, can show image persistence, also known as image sticking, if the same pattern is left on the display for extended periods of time.

  • Page 12: Safety

    Internal diagnostics Safety Safety Internal diagnostics The module performs a number of self-checks that improve safety. Checks include monitoring of voltage supplies, checksums on memory and a watchdog that monitors software execution. The module is using a real time operating system which supervises software execution.

  • Page 13: Mounting

    • The part number for the MD4-5 bracket kit is 20077779. See ’Appendix C’ for RAM™ and Southco mounting pattern dimensions. The IQAN-MD4-10 does not require a bracket. It has a VESA 75 mounting pattern on the back surface which will also accept RAM™ mounts.

  • Page 14: Mounting Considerations

    Mounting Mounting considerations OTICE IQAN-MD4 shall be positioned in the machine per the following instructions: • The unit is designed for outdoor use. Position the unit in desired location and make sure that it is not exposed to mechanical damage.

    Supply voltage Supply voltage Before any installation of the IQAN system can take place, make sure the ignition lock is turned off and the battery is disconnected. Emergency stop Make sure an Emergency Stop disconnecting the power supply, is easily accessible at any time.

  • Page 19: Addressing

    Identification of an IQAN-MD4 by address For normal operation of an IQAN-MD4 in a single master system, the ID-Tag is still used. When no ID-Tag is installed, the MD4 will start in safe mode. The connection of an ID-Tag between ADDR-H and ADDR-L will assign an address to the IQAN-MD4 master module.

  • Page 20: Diagnostic Interfaces

    A high-speed CAN interface is needed to use this feature. Contact Parker for information about supported CAN interfaces. A termination resistor is usually required at the CAN interface on the PC. Parker part number 5030082 or 5030182, or an equivalent 120 ohm resistor may be used. A flying lead cable may be connected to the IQAN master to provide a connector interface.

  • Page 21: Ethernet Diagnostics Communication

    IQANdesign/IQANrun. On port A, the IP address is automatically assigned using DHCP. It is recommended to use an environmentally sealed panel mounted RJ45 connector for easy access. Parker part number 20077785. Video input The IQAN MD4 master modules are capable of showing video inputs from an external source.

  • Page 22: Analog Cameras

    It is also possible to connect an analog camera by routing the video feed through a video server with ethernet connection. In this case, it is the video server that needs to have the correct IP address set. Instruction book, IQAN-MD4...

  • Page 23: Reference Voltage, Vref

    VREF. The standard reference voltage will feed different kinds of sensors and potentiometers. On the IQAN-MD4 there is no -VREF pin, instead the -BAT is used as -VREF. To get the best result, connect as close to the connector as possible to minimise voltage fluctuations.

  • Page 24: Voltage Inputs

    Voltage inputs Voltage inputs Connecting sensors to the voltage inputs The sensor signal range must be 0-5 Vdc. To detect signal errors such as short circuits or interruptions the active signal range be within 0.5-4.5 Vdc. Error detection range Active signal range Error detection range Active signal range.

  • Page 25: Connecting A 2-Wire Temperature Sensor To Voltage In

    Voltage inputs Connecting a 2-wire temperature sensor to voltage in When you connect a PTC (positive temperature coefficient) temperature sensor you may need to use a pull up resistor on the input signal. Please check the technical data for your specific temperature sensor. EXAMPLE Connect the negative terminal of the temperature sensor to -VREF, and the signal to VIN-X.

  • Page 26: Connecting Switches To The Voltage Inputs Using +Bat

    Voltage inputs Connecting switches to the voltage inputs using +BAT It is recommended to connect system voltage +BAT to the input through a switch in order to reserve 5Vdc VREF for sensors and potentiometers. EXAMPLE Connect the positive and negative terminals of the switch to supply or the unit’s +BAT, and DIN-X, respectively.

  • Page 27: Directional Pulse Count Input

    Directional pulse count input Directional pulse count input Connecting a directional pulse count channel (DPCNT) The DPCNT is a physical analog input. The directional pulse count input channel is used to count pulses. It is bi-directional, which means it can add and subtract pulses. The DPCNT is primarily designed for input from an encoder wheel.

  • Page 28: Low-Side Digital Outputs

    Low-side digital outputs Low-side digital outputs The low-side digital outputs are designed to drive small loads, e.g. lamps and buzzers. Low-side digital outputs work by grounding a signal through the module. See Appendix A for maximum loads per output. EXAMPLE Connect the lamp to the low-side digital outputs using a DOUT(LS) position, and the +BAT, as supply.
