 SEM3™ Metered Bus Plug for SENTRON Busway Systems

  How to "Ping" your SEM3 Controller: (Default IP address:  
 192.168.1.65)

  Open a Command Prompt and in the prompt type "ping"  
  followed by a space and the IP Address of the SEM3™ and press  
 

Enter

. (Do NOT type the quotation marks.)

  The following should appear in the prompt window:

    Pinging 192.168.1.65 with 32 bytes of data:
    Reply from 192.168.1.65: bytes=32 time=56ms TTL=250
    Reply from 192.168.1.65: bytes=32 time=60ms TTL=250
    Reply from 192.168.1.65: bytes=32 time=69ms TTL=250
    Reply from 192.168.1.65: bytes=32 time=78ms TTL=250
    Ping statistics for 192.168.1.65:
      Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
      Minimum = 56ms, Maximum = 78ms, Average = 65ms

  If not, then check your connection between the PC’s Ethernet  
  port and the Controller MODBUS TCP/IP port.

  Open a browser (such as Explorer, Chrome, etc.) and type the IP
   address 

192.168.1.65

 in the top window. Default user name

   is 

admin.

 Default password is 

SEM3

. User name and password  

  can be set to user preference and ARE case-sensitive. Default  
  login brings user in at Supervisor level so that all screens can be  
  seen and modified. It is recommended that user account(s) and  
  password(s)be set as soon as possible. 

  To reset user name and password navigate to the 

User Profile 

 

 page.

7.3 Addressing the Meter Racks
 

SEM3™ meter racks are hard-coded with discrete addresses  

  that allow simultaneous module-to-controller communications.  
  Three and six meter racks have a rotary dial for adjusting  the  
  racks address range. All meter racks are shipped from the  
  factory with the rotary switch set to 0. Upon installation and  
  set-up the installer must adjust the rotary switch to uniquely  
  address each rack networked with a common controller. See  
  Table 1. The rotary switch is shown in Figure 10.

Figure 10: Six Pole Meter Module Rack with 10 Position Rotary  
Switch 

 

Note: 

Meter racks are internal to the bus plug. However, a view  

  port with rotary switch access hole allows the user to ensure  
  proper phasing of the meter modules and verify that they are  
  receiving power. The small hole over the rotary switch allows for  
  the rack to be addressed without opening the bus plug cover.  
  The location of the six meter rack is shown in Figure 11. It may  
  be necessary to remove the front cover of the plug to access and  
  adjust the rotary switch. Loosen the two thumb screws on the  
  bus plug cover to access the rack. 

 

DANGER: Ensure that breakers are in the OFF position before  

  removing the bus plug cover. Contact with live conductors  
  will result in serious injury or death.

   

Figure 11: Internal Location of Meter Module Rack In Metered  
Bus Plug

  Note that the internal layout of the bus plug is common for  
  metered and controller bus plugs. In either case, the rotary  
  switch must be adjusted to suit the network configuration. See  
  Table 1.

  Depending on the number of "daisy chained" bus plugs, three
   meter module rack rotary switches are set to one of the  
  following: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E or F. Each  
  "daisy chained" meter module rack communicating with the
   same controller must be assigned a unique switch setting.  
  Similarly, six position racks are set to one of the following: 0, 1,  
  2, 3, 4, 5, 6, 7, 8 or 9. This is illustrated in Table 1.

  It is critical to note that there is an exclusivity condition for
   the six meter module racks. 

0

 and 

8

 cannot both be chosen

   as rotary switch settings for six position racks communicating  
  with the same controller. This is also the case for six position
  rack designations 

1

 and 

9

. This is because Modbus addresses  

  cannot be repeated when communicating with the same  
  controller.  See Table 1.

  If a combination of three and six meter plugs is required then
   the user must ensure that the corresponding Modbus addresses  
  are not repeated between the three and six meter racks. Also  
  remember that the maximum number of poles that the  
  controller can monitor is 45 (given cable length restrictions in  
  section 6.3).
