TF thermistor and TH bimetallic switch
The winding temperature is monitored using TF thermistors or TH bimetallic switches.
The connection is made at the TF output VOTF and the TF input DI05TF of
MOVITRAC
®
. The binary input DI05TF must be set to TF signal. The temperature will
then be monitored by MOVITRAC
®
; no additional monitoring unit is required.
A connection can also be made to 24VIO and a binary output when using TH bimetallic
switches. Set the binary input to /External fault.
8.9
Connecting braking resistors BW.. / BW..-T / BW..-P to X3 / X2
A terminal must be set to "/Controller inhibit". K11 must be opened and "/Controller
inhibit" must receive a "0" signal in the following cases:
•
BW...-...-P: The auxiliary contact trips
•
BW...-...-T: The internal temperature switch trips
•
BW...: The external bimetallic relay F16 trips
The resistor circuit must not be interrupted.
