Restart interlock (manual reset) (bridge 1)

By bridging DIAG IN (pin 5) and DIAG OUT (pin 6), the restart interlock 

(manual reset) is activated

Protective mode (bridge 2)

By bridging DIAG OUT (pin 6) and enable (pin 1), the automatic 

protective mode is activated Do not connect S1

K1, K2:

Relay for processing the switching outputs  

OSSD 1,OSSD 2

Kn1, Kn2: Auxiliary contacts of the last switching relay (optional) 

signals at input EDM (pin 8): only to be connected when 

the function is activated

S1:

Command device for restart (optional)

E1:

Power supply 24 VDC +/-10%

For proper functioning, the operating mode restart interlock 

or operating mode automatic is to be wired

Upon delivery, the "contactor control" function is deactivated 

The function is activated by means of the NSR0801 BUS 

converter and the PC software
