Standstill Monitor

SAFEONE DN3PS2

The SAFEONE DN3PS2 is a safety switchgear for sensorless standstill monitoring of three-phase and single-phase motors. Standstill detection is performed in the device by evaluating the EMF. The module complies with certified Performance Level e and SIL 3.

Safe Standstill monitoring easy as pie.

The standstill monitors from our SAFEONE Standalone Series do not require a motor feedback measuring system, which makes them truly unique on the market. They safely monitor 1- and 3-phase motors up to 690V AC with Performance Level e according to DIN EN ISO 13849-1. The DN3PS2 standstill monitor measures the electromagnetic force (EMF) when the motor runs down. The potential-free output contacts switch when the switching threshold, which can be parameterised on the device, is undercut.

Block diagram (terminal assignment 33PS02, 33PS03, 33PS05)

Two different function types are possible with the variants 33PS02, 33PS03, 33PS05.
The function type is selected via inputs I11 and I21.

Function 1	Function 2
I11 and I21 not connected	I11 and I21 connected
Standstill monitoring is constantly active.	Standstill monitoring is not active.
Close the enabling contacts when the drive is at a standstill.	Enable contacts are closed (with 33PS05 only the enable contact 13/14 remains closed. The enable contact 23/24 switches off on movement).
	The error detection "wire breakage and "single-channel" is inactive. (not with 33PS05)
