2. The STO inputs are monitored continuously every 1ms. If one or both STO inputs are at
level zero and the MOSFET driver supply voltage has not dropped, an STO fault is detect-
ed. The STO fault flag is set. A user digital output can be activated to indicate the fault.
Installation – Maintenance
The STO circuit needs to be tested before first installation and at least every 3 months
according to the below sequence:
1. Activate STO (both logic level 0)
2. Check that STO is active (through Roborun+ Utility/Serial)
3. Check that there is no STO fault present (through Roborun+ Utility/Serial)
4. Deactivate STO 1 and STO 2 (both logic level 1)
5. Check that STO is not active and that there is no STO fault present (through Robo-
run+ Utility/Serial).
SAFETY INSTALLATION
It is required that the controller has to be placed in an enclosure that can provide
IP54 protection.
SAFETY REGISTRATION
It is required that STO end user should follow up www.roboteq.com and register to
site/forum for any news about safety function.
STO Voltage source specification attention
In order to have maximum response at STO implementation, user/installer/integrator
should use voltage source with low output capacitance. In any other case, latency in acti-
vation might occur.
Compliance and Safety Metrics
The STO function is compliant to:
IEC 61800-5-2:2007, SIL 3
IEC 61508:2010, SIL 3
IEC 62061:2005, SIL 3
