Funkcje

SNO 4063K

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 positively driven relays.
Basic function
After supply voltage has been applied to terminals A1 / A2 and the safety inputs closed, operating of the reset button closes the enabling current 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 safety channels CH1 and CH2 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 the positive potential (S11 to S12), and safety channel CH2 to the negative potential (S21 to S22).
• Manual start
When the safety inputs are closed, a button is used to open reset input S34 (triggering with falling edge) or to close 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 safety 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.
• Synchrocheck
With two-channel control both safety channels are monitored against one another with the synchronous time tS . Safety channel CH1 must close before CH2 and bridge S33 / S35 must be connected. If CH2 closes before CH1, the
synchronous time is t S =∞ 

SNO 4063KM

The function of this device corresponds to that of the SNO 4063K without synchrocheck. The device is suitable for connecting to light curtains for Si category 4 and to short-circuit forming 4-wire safety mats, switching strips or switching edges (without monitoring 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 open and the  SUPPLY LED flashes.
•Light curtain for Si category 4
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.
•Input debouncing
Input debouncing prevents fast consecutive switching of the enabling current paths when the safety inputs are opened for less than t ASP
Safety inputs opened for longer than t ASP lead to opening of the enabling current paths after t R . Restarting is blocked for time t SP
For applications with tactile operating modes (rapid ON-OFF cycles, for example at
manual supply) we recommend the use of SNO 4063KM

Proper use
The devices are safety switching devices. They must only be used as components  of safety equipment on machines for the purpose of protecting persons, material and machines.
• The safety category according to EN 954-1 depends on the external circuitry, the
choice of control devices and their placement on the machine.
• The indicated times must be observed when the device is operated, otherwise the
device could lock. Locking can be released by properly opening the safety inputs.
• SNE expansion devices or external contactors with positively driven contacts can
be used to multiply the enabling current paths.
• The device and the contacts must be protected with max. 6 A utilization
category gG or through circuit breakers with trigger characteristic B or C.
• The devices are equipped with overload protection (for short circuit). After the
cause of the malfunction has been removed, the device is operational again after
approx. 3 s.
• Control output S11 is exclusively for connecting control devices as defined in the
operating instructions and not for connecting external devices such as lamps, relays
or contactors.
• The devices must be installed in a control cabinet with a protection degree of at
least IP 54
