Safety Relay on the Sawyer malfunction for external safety trigger

Recommended Posts

Hi There,

I'm new to sawyer robot and i must say integrating external safety devices and controlling the sawyer remotely from a PLC via a simple start, stop and safety reset is not straight forward as compared to the other robots I have integrated to PLC and safety system.

I'm trying to use a three push-button - Start/Resume, Stop and Safety reset which are controlled through a PLC. I found there are only non-safety signals that go through  SC26  safety relay! The three non-safety IN11, IN12, and IN13 do not come with Nonsafety robot stop or pause.  Any of the external safety inputs - IN 15-16 and IN17-18 act as safety stop which is not I want it to happen.  Is there a way to stop/ pause the robot without tripping the safety through hardwire signals?

For tripping the robot using a safety mat or Light curtain  I simulated by sending control voltage as per the manual. The robot's safety trips but the SC26 goes into fault mode and the signal on IN13 has no impact.  This is very odd and nothing is explained in the manual. Does the SC26 safety relay in the sawyer need re-programming?  I'm surprised  to see there are no jumpers in the safety input channel.


Please, can anyone help? I have a tight deadline.
