Monitoring Technique VARIMETER Standstill Monitor BD 5936 Your Advantage Standstill monitoring without sensor Features According to IEC/EN 60255-1, IEC/EN 60255-26 For standstill monitoring of 3- and 1-phase asynchronous motors Line breakage detection in the measurement circuit Forcibly guided output contacts: 2 NO, 2 NC contacts for 250 V AC LED indicators for motor standstill, line breakage, and operating voltage 2 Wire connection: also 2 x 1.5 mm stranded ferruled (isolated), DIN 46 228/-1/-2/-3/-4 or 2 2 x 2.5 mm stranded ferruled DIN 46 228-1/-2/-3 Width 45 mm Product Description Approvals and Markings The BD 5936 detecting standstills of 3- and 1-phase asynchronous mo- * * tors. At 2 terminals of the stator winding the BD 5936 measures the volta- ge of the slowing motor which has been induced.. If the induction voltage approaches 0 this indicates that the device is at a standstill and the output Canada / USA A025518 * see variants relay is activated. Additional the monitor detects strand breaks between measurement in- Applications puts Z1 / Z2.. 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 For detecting standstills of 3- and 1-phase asynchronous motors, for ex- can only be cleared by (briefly) switching off the auxiliary voltage. ample, for releasing protective door interlocks of machine tools or for ac- tivationg stopping brakes. Function Diagram 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.
