How to maintain and install Bosch Rexroth IndraControl HMI?

• 1.1 General Information
  
  Bosch Rexroth IndraControl operator terminals are maintenance-free. A few parts aresubject to wear and must be replaced after a certain number of operatinghours.




• 1.2 Exchange of Hardware Components
  
  CAUTION
  Maintenance work in the device is only permissible by skilled stuff!
  If hardware components have to be exchanged, please contact the Bosch Rexroth Service or ensure that only skilled stuff changes the respectivecomponents.




• 1.3 Data Backup
  
  CAUTION
  The Bosch Rexroth AG is not liable for possible data loss and thedamages resulting from this!
  The customer himself is responsible for the backup of customer-specific data and must provide this data in case of service.




• 1.4 Unpacking the Device
  
  Unpack all parts carefully and check the contents for any visible damagein transit. Also check whether the shipment matches the specificationson your delivery note.
  
  If you notice damages in transit or discrepancies, please contact oursales department immediately.




• 1.5 Identification
  
  You can identify the small operator terminal by the nameplate on therear.
  
  

  

  1 Ordering name / Short type designation
  2 Part number
  3 Voltage and power specification
  4 Serial number
  



• 1.6 Connecting the Device
  
  1.6.1 Supply Voltage 24 V
  
  The supply voltage is supplied via connector X1.
  
  The device has reverse polarity protection. In case of wrong polarity,the device will not operate.
  
  This is a protection class I device. For safe operation, safety extra-lowvoltage (SELV) in accordance with DIN EN 61131 must be used for thesupply voltage.
  
  Connector in the small operator terminal: 3-pin connector PhoenixCOMBICON MSTBV 2,5/3-GF.
  

  

  
  A suitable female connector strip of the type Phoenix COMBICONMSTB 2,5/3-STF is supplied.
  
  Use the following procedure to connect the device to the supply voltage:1. Remove approx. 30 mm (1.181") off the outer cable sheath and approx.5 mm (0.197") off the wires.
  

  

  
  2. Fit the wires with wire end ferrules and connect the wires to the connector.
  
  

  

  
  3. Plug the female connector strip onto connector X1.
  
  

  

  
  4. Secure the female connector strip in place with a screw-type lockingto prevent it from slipping out.
  
  

  

  
  

• 1.7 Front Panel
  
  Only use a damp cloth to remove any dirt from the front panel




• 1.8 Fuse
  
  The semiconductor fuse cannot be replaced!
  
  A semiconductor fuse is used to protect the device. Once the fuse hasbeen tripped, the device must be disconnected from the supply voltageto allow the semiconductor fuse to regenerate. At an ambient temperatureof 20 °C (68° F), the regeneration takes approximately 20 seconds.The higher the ambient temperature, the longer the regenerationtakes.




• 1.9 Battery
  
  The built-in battery preserves the data in the SRAM and supplies thereal-time clock with power. The minimum battery life is 5 years, evenunder unfavorable operating conditions. When the battery runs down,the message "Change battery" is generated automatically.
  
  We recommend you change the battery approximately every 4 yearsas part of the regular maintenance work. A pre-assembled batteryincluding connector can be obtained directly from Bosch Rexroth (orderdesignation: VAS04.1-001-002-NN, MN: R911316662).
  
  If the "Change battery" message is detected too late, data in the SRAMmay have already been lost. For this reason, after changing a battery,always check data such as editable passwords, parameters in the systemvariables, data sets of the recipes and entries in the message system.




• 1.9.1 Changing the Battery
  
  To ensure that the data in the SRAM and the time are preserved, it ispossible to change the battery under operating voltage. Observe thecorresponding safety notices!
  
  1. Remove the screws on the rear panel of the device and lift off theenclosure cover.
  2. Remove the adhesive tape securing the battery.
  3. Disconnect the connector from the battery and remove the dead battery.
  4. Plug in the cable for the new battery.
  5. Use the included adhesive tape to attach the new battery to the enclosure.
  6. Place the enclosure cover back onto the device.
  7. Carefully tighten the screws of the enclosure cover.
  




• 1.9.2 Battery Disposal
  
  To prevent short circuitry in the collection boxes, insulate the poles ofeach battery with insulation tape or put each single battery into a plasticbag.
  
  You must always return old batteries to a dealer or to a returns depotset up for this purpose by the public waste disposal body or a licensedbattery dealer for recycling. Only dispose of dead batteries in public orcommercial collection boxes. The battery is drained when the message„Change battery“ appears on the display of the device.
