4.3 Instructions for connection
4.3.1
Temperature sensor
Bender IT system transformers are equipped with the temperature sensors required accord-
ing to their insulation class. These temperature sensors (maximum of 6 sensors connected in
series) are connected to terminals X3:35 and X3:36.
4.3.2
Alarm indicator and test combination
Ex works, the following pairs of terminals are provided for the connection of BMS bus de-
vices:
X3:29 and X3:30 (A/B)
X3:31 and X3:32 (A/B terminals are terminated with 120 Ω at the factory)
Alarm indicator and test combinations, panels and other Bender-BMS-bus devices can be
connected.
1. A BMS device or an existing BMS bus with several devices is connected to terminals X3:29 and
X3:30:
The last device at the other end of the bus must be terminated with 120 Ω.
Terminals X3:31 and X3:32 remain terminated.
2. An existing BMS bus that has already been terminated on both ends, is disconnected; one
open branch is connected to terminals X3:29 and X3:30, while the other one is connected to
terminals X3:31 and X3:32:
The 120 Ω resistor, provided ex works, must be removed and the open bus branches must be
connected to the specified terminals.
Please read the information on cable routing in the "BMS bus" instruction leaflet.
The AN450 power supply unit can supply power to a maximum of 3 MK2418 or 2 MK2430
alarm indicator and test combinations via the terminals X3:33 and X3:34. In this respect,
please refer to the documentation for the relevant devices. The AN450 is not suitable for sup-
plying power to TM... operator panels.
4.3.3
SCADA system (Supervisory Control And Data Acquisition)
If messages from the UFC107E-.. changeover and monitoring module are to be transmitted
to a SCADA system, you have the following options:
Protocol converter (gateways)
OPC server
Common alarm via the relay outputs of the 107TD47 A-ISOMETER® and the PRC487 control
device
Conversion between BMS bus and digital inputs and outputs by means of alarm indicator and
operator panels (TM...) or signal converters (SMO480-12, SMO482-12, SMI 472-12).
