What to do if socomec ATyS g M does not switch over when the Priority SOURCE is restored?
If the Socomec Switch doesn't switch over when the Priority SOURCE is restored, check the state of the "Priority Source Availability" LED. If this LED is off, refer to the troubleshooting steps for when the "Priority Source Availability" LED does not come on.
What to do if my socomec Switch does not switch over after losing the priority source?
If your Socomec Switch doesn't switch over after the priority source is lost, here are a few things to check: * Ensure the device isn't in manual mode by closing the cover for automatic operation. * Verify that external control commands aren't inhibiting automatic operation via terminals 207-210. * Check the status of the Emergency Source availability LED, and if it's off, refer to troubleshooting steps for that specific symptom. * For transformer setups, confirm the Main Failure Timer (FT) setting and use a stopwatch to ensure switching occurs after the FT countdown.
What to do if my socomec Switch does not switch over when the priority source is restored?
If your Socomec Switch isn't switching back when the priority source is restored, consider these points: * First, make sure the device isn't in manual mode by ensuring the cover is closed for automatic operation. * Next, check that external control commands aren't preventing automatic operation through terminals 207-210. * Examine the Priority Source Availability LED; if it's off, consult the troubleshooting steps for that specific issue. * Verify the Main Return Timer (RT) setting, using a stopwatch to confirm the switch to the priority source after the RT timer elapses. * Also, ensure the manual retransfer function isn't active by checking that contact 207-208 is open (deactivated) if this function isn't needed.
What to do if socomec ATyS g M Switch remains off after priority source loss?
If your Socomec Switch remains off after losing the priority source, check the voltage across the emergency source power supply terminals: * For 127 / 230 Vac models, ensure voltage is between 176 to 288 VAC across terminals 3-5. * For 230 / 400 Vac models, check terminals 1-7. If using a transformer or generator set (Genset), verify that the Main Failure Timer (FT) has completed its countdown. Use a stopwatch to measure: * Contact 73-74 should close after a maximum of 60 seconds (M-G application). * The Genset run command is Contact 73-74 Closed, and the Genset stop command is Contact 73-74 Open.
How to fix socomec ATyS g M if the "Priority SOURCE Availability" LED does not come on?
If the "Priority SOURCE Availability" LED on your Socomec Switch does not come on, check these parameters: the type of network (3P or 1P) using DIP Switch 1, the frequency (50 Hz or 60 Hz) using DIP Switch 2, and the nominal voltage by measuring the voltage across the terminals with a multimeter and adjusting the potentiometer accordingly.
Why "Emergency SOURCE Availability" LED does not come on socomec ATyS g M?
If the "Emergency SOURCE Availability" LED on your Socomec Switch does not come on, check the following parameters: the type of network (3P or 1P) using DIP Switch 1, the frequency (50 Hz or 60 Hz) using DIP Switch 2, and the nominal voltage by measuring the voltage across the terminals with a multimeter and adjusting the potentiometer.
What to do if socomec ATyS g M Switch remains switched off after the Priority SOURCE is lost?
If your Socomec Switch remains switched off after the Priority SOURCE is lost, check the voltage across the power supply terminals of the emergency SOURCE. For the 127/230 Vac model, check terminals 3-5. For the 230/400 Vac model, check terminals 1-7, ensuring the voltage is between 176 to 288 VAC.
