7.1
Figure 13
The use of MCR-S-…-DCI modules in one or more supply phases of the motor enables what is known as "motor monitoring"
(Figure 13). The MCR current transducer can transfer corresponding standard signals about the motor load to the control
system or service personnel. The true r.m.s. value measurement process means that AC, DC, and distorted currents can
be measured. Even higher frequency currents up to 1 kHz can be acquired.
7.2
Figure 14
Large industrial motors must be overhauled and serviced at regular intervals. Installing an MCR current transducer in one
phase of the motor feed line enables pulses to be generated with the relay or transistor switching output that can be
measured using a simple meter (Figure 14). The service personnel can then use the motor starts and peak loads as a basis
to provide efficient maintenance corresponding to the number of overloads.
7.3
MCR current transducers can be used for monitoring lighting. If the strength of the current in a circuit is above or below a
specified value after a suppressed switch-on time, there is a fault in the lighting circuit. If the lighting circuit fails, this signal
status can be passed on to another control unit and the emergency lighting can be switched on. The same method can also
be used with other power loads.
