Safety switch / safety door SNO 4062K / SNO 4062KM

Stop Category 0 according to EN 60204-1

• Reset button monitoring
• Manual or automatic start
• Single-channel or two-channel control
• Cross monitoring
• 2 enabling current paths, 1 signal current path

Application

• Protection of people and machinery
• Monitoring of emergency stop applications
• Monitoring of safety gates
• Monitoring of light barriers
• Up to PL e / Category 4 (EN ISO 13849-1)
• Up to SIL CL3 (EN 62061)

Function
The device is a two-channel switching device for emergency stop applications with self-monitoring on each ON-OFF cycle. It complies with EN 60204-1 and is equipped with forcibly guided relays.
Basic function:
With supply voltage applied to terminals A1/A2 and the safety inputs closed, pressing the reset button closes the enabling curre nt paths (manual start). When the safety inputs are opened/de-energized the enabling current paths will open.
Operating modes / system functions
•Single or two-channel control With single-channel control both CH1 and CH2 safety channels are connected in parallel; with two -channel control they are switched separately.
•Without cross monitoring Both safety channels are switched to the positive potential (S12 and S31 to S11).
•With cross monitoring Safety channel CH1 is switched to positive potential (S11 to S12), and safety channel CH2 to negative po tential (S21 to S22).
•Manual start
When the safety inputs are closed, a button is use d to open reset input S34 (triggering with falling edge) or to clos
e reset input S35 (triggering with rising edge).
• Automatic start
Reset input S35 is connected to S33. The device starts with the rising edge of the signal on safety input S12.
•Start inhibit
After supply voltage has been applied and the safe ty inputs closed, the enabling paths will not close. Starting is only possible after the reset button has been operated. For start inhibit the reset inputs have to be controlled with
the button, as with manual start mode.
•Restart inhibit
No restart after the safety inputs have been opened and closed. Restarting is only possible after the reset button
has been operated. For restart inhibit the reset inputs have to be activated with the button, as in manual start
mode.
•Semiconductor compatible
OSSD (output signal switching devices) signals from a light curtain or other safety sensors with semiconductor outputs can be processed. Test pulses <t TP do not influence the device functions. Test pulses >t TP can lock the device.

SNO 4062K
The function of this device corresponds to that of the SNO 4062K without synchro check. The device is suitable for connectin g to light curtains for Type 4 (EN 61496-1) and connecting to short-circuit formin g 4-wire safety mats,
switching strips or switching edges (without monito ring resistance).
•Safety mats
The device must be operated with two channels and cross monitoring. If there is resistance < 50 Ω / channel and
a short circuit between the channels (S11/S12 and S21/S22) the enabling paths o pen and the SUPPLY LEDs flashes.
•Light curtain for Type 4 (EN 61496-1)
The device will be operated with two channels and without cross monitoring, if the light curtain connected to the
OSSD detects a shunt fault on its own. For applications with tactile operating modes (rapid ON-OFF cycles, for example with manual supply) we recommend using SNO 4062KM
