      Are spare keys available for part number 31VK1?

      Keys can be provided as special order.

      In the 31VK1 series can the key be removed in the " on " position ?

      No , to remove the key in the " on position a 31VK2 is required , 31VK1 will only allow key removal in the " Off " position.

      Can i get multipule 31VK1 switches with the same key?

      Yes, you can get multiple 31VK1 switches with the same key.
      If you put CK after the part number they come with the same key.

      Some of the key features are:
      • Key Operated Switches
      • Common Keyed
      • Locks in off position

      For further information please visit https://www.clipsal.com/Trade/Products/ProductDetail?catno=31VK1CK

       

      Do you offer a key switch like the 31VK2 but in the 2000 Series?

      No, Unfortunately we do not offer a key switch in the 2000 series. The only series we offer a key switch is the Standard Series and the industrial 56 Series.

      Is there a lockable double GPO in any residential range?

      No there isn't but you can install a 31VK1, upstream from the GPO and control the power to it that way...

      In the 31VK switches what is the difference between a K1 and K2?

      The 31VK1 can have the key removed in the OFF position only while in the 31VK2 the key can be removed in both the ON and OFF positions.

      For further information please visit https://www.clipsal.com/Trade/search-results?q=31VK

      Can the key be pulled out in both ON and OFF position in 31VK2 and 31VK2/2 key operated switches?

      Yes, the key can be pulled out in both ON and OFF position in 31VK2  (one way) and 31VK2/2 (two way) key operated switches. They lock in ON and OFF position

      No, unfortunately the key switch mechanisms are not removeable and therefore cannot be put onto any other plates.
      Some of the key features for the 31VK Series are:
      • 1 gang
      • Dimension: 115 mm Length x 73 mm Width x 11 mm Depth
      • Mounting centers: 84 mm
      • Common keyed switch
      • Locks in on and off position

      Data Center Expert | When polling dual registers, both registers must be polled together.

      Issue:
      When polling dual registers in InfraStruXure Central / StruxureWare Data Center Expert, both registers must be polled together.

      Product Line:
      InfraStruXure Central / StruxureWare Data Center Expert

      Environment:
      Modbus communications

      Cause:
      Modbus registers are limited in size, which limits the values they can store and return to a BMS. Unsigned values can not exceed 65535. Because some values returned by ISXC may be greater than this maximum value, we have created the ability to use 2 registers together as a pair to allow for this larger output. If you choose to configure 31001 as a dual register, it will encompass 31001 and 31002.

      Resolution:

      When polling these registers, poll both 31001 and 31002 (or whatever register pair you have set up this way) during the same poll. Failure to do so will return invalid results.
       

      Can StruxureWare Data Center Expert output a 32 bit register with its Modbus output?

      Issue:

      A single register in StruxureWare Data Center Expert's modbus output is limited to 16 bit.

      Product Line:

      StruxureWare Central / StruxureWare Data center Expert

      Environment:

      StruxureWare Central any version
      StruxureWare Data center Expert any version

      Cause:

      The output of a single register for StruxureWare is a 16 bit unsigned integer. This means that any value larger than 65535 can not be handled by a single register. This includes values lower than 65535 that report with a decimal such as 6553.5. DCE will output 65535 but your BMS will need to divide by 10 in such cases.

      Resolution:

      We can not output a 32 bit register in StruxureWare. To overcome this limitation, StruxureWare Data Center Expert can be configured to output a value to 2 registers. This must be configured during the initial setup for the output of each register. StruxureWare does not know which registers may be too large for an individual register so each must be done manually. Each should be polled a 16 bit unsigned integer

      To configure this option, go to the system menu and building management settings. Select the device that you will be using and choose modify device settings. If you double click any register, you get the option to "Edit the Slave Sensor Register Value" which is not necessary and you get the option to "Edit the number of registers used for this sensor". This second field can take a value of either 1 or 2. For values above 65535, you must enter the number 2 and hit OK. If the register chosen was 31000, the next available register will now be 31002. The sensor that may have been set to use 31001 will now change. This is also why this should be done upon initial setup as if the system is already configured and a register is changed, the polling software must be reconfigured with the new registers.

      If you set 31000 to a double register, you then need to poll 31000 and 31001. you then take the 1st register and left shift the first register (31000) by 16. In binary, it would look like this:

      Assuming a value of 131071, a 32 bit register would return:
      00000000000000011111111111111111

      With 2 registers, you must poll both.
      31000 returns 0000000000000001 If this were a single register, = 1
      31001 returns 1111111111111111 = 65535

      With 2 registers however, you must left shift the 1st register and add it to the second.

      00000000000000010000000000000000 is the 1st register left shifted by 16 and is equal to 65536.
      Add this value to the value returned from the second register:
      1111111111111111 = 65535


      Now you have a 32 bit number capable of holding values up to 4,294,967,295
      00000000000000011111111111111111 = 65535 + 65536 = 131071

      This math must all done on the side of the querying application.
