SAFEONE DN3PS2 Standstill Monitor

The standstill monitors from our SAFEONE Standalone Series do not require a measuring system, which makes them truly unique on the market. They safely monitor 1- to 3-phase motors up to 690V AC with Performance Level e according to DIN 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)

Your advantages summarised

DN3P SAFEONE-Serie

Cost-efficient

No external measurement systems equals less components, lower costs as well as faster Certification and Validation.

Be independent

Can be used on all three-phase and single-phase motors up to Performance Level e, regardless of supplier and system.

Fits into every cabinet

With an overall width of only 22,5 mm/0.9 in

Tailored to your needs

SAFEONE DN3PS2 can be configured exactly for your needs:

Adjustable switching threshold 50-500 mV
Various adjustable delay times

Easy Configuration

Dependent on the model, via USB interface on the PC or directly via SET key. In the case of our rotational direction monitor, no parameterization is necessary at all.
