1.5 Connection BCI via integrated RJ11 jack (X56)


If the BCI (RJ11 jack) is not used, protection against electric shock hazard must be
provided (jack must be covered up)
 The signal cable for the AZL2 or other accessories, such as the OCI410 interface
(plugs into the RJ11 jack), may be connected or disconnected only when the LMV27
is dead (all-polar disconnection), since the BCI does not ensure safe separation from
mains voltage
 The AZL2 is designed for direct connection to the integrated RJ11 jack at the LMV27
 The signal cable from the LMV27 to the AZL2 must conform to certain specifications.
Siemens has specified the signal cable for use under the burner hood. When using
signal cables of other manufacture, Siemens requirement are not necessarily met
 Do not lay the signal cable from the LMV27 to the AZL2 together with other cables.
Use a separate cable
 Service operation with a longer signal cable from the LMV27 to AZL2
If a longer cable is required for service work for example (short-time usage, <24
hours), note that the above application under the burner hood no longer applies and,
for this reason, the cable may be subjected to increased mechanical stress. In that
case, use a reinforced cable
 Both the signal cable and the AZL2 must be shipped and stored in a way that no
damage due to dust and water can occur when the products are used in the plant
 To ensure protection against electric shock hazard, make certain that, prior to
applying power, the signal cable is correctly connected to the AZL2
 The AZL2 must be used in a dry and clean environment
Connection of OCI410 interface to the BCI
Connect the OCI410 interface without other extension to the USB port of your PC
according to the example given below.
