## **applications** 

For detecting standstills of 3- and 1-phase asynchronous motors, for example, for releasing protective door interlocks of machine tools or for activationg stopping brakes. 

## **function** 

At 2 terminals of the stator winding the BD 5936 measures the voltage of the slowing motor which has been induced by residual magnetism. If the induction voltage approaches 0 this indicates that the device is at a standstill and the output relay is activated. 

At the same time the monitor detects strand breaks between measurement inputs Z1 / Z2 by means of a 6-volt direct current generated by the monitor. If a line breakage is detected, the output relay goes into the normal position (as when the motor is running). This state ist saved and can only be cleared by (briefly) switching off the auxiliary voltage.

## **Notes** 

In the case on the motor wires the Z1 / Z2 connection wire should be installed separately from the motor supply and connected directly to the motor 

terminals. For longer distances please use twisted pair wires. 

**Indicators** ~~ee~~ 1st green LED: comes on when operating voltage present 2nd green LED: comes on when motor at a standstill Red LED: comes on in event of line breakage between Z1 and Z2
