What should I do if the fault LED is on (ATS Controller) on socomec Switch?
If the fault LED is on for the ATS Controller, switch the ATyS t from AUT to Manual and back to AUT. If the fault condition persists, contact SOCOMEC.
What to check if electrical operation of socomec ATyS t Switch does not correspond to external order I,O,II?
If the electrical operation of the Socomec Switch does not correspond to external order I, O, II, verify the selected control logic wiring (impulse or contactor) and the connector connections.
Why are the sources availability LEDs and fault LED blinking on socomec ATyS t?
If the sources availability LEDs and the fault LED are blinking on the Socomec Switch, check the phase rotation consistency and the neutral position consistency between both sources.
What to do if the ready light remains flashing on socomec Switch?
To get a steady READY light either revert to the settings in the ATyS t or save the new settings. To save, put into manual mode and press the PROG OK button momentarily.
Why is the AUT light flashing on my socomec ATyS t Switch?
The AUT LED will be steady green when in AUTO Mode and will be flashing green when the ATyS t has timers running. This is usually a normal indication.
What to do if ATyS t Socomec Switch does not operate electrically?
To resolve this, verify the power supply on terminals 101-102 and 201-202: 208 - 277 Vac ±20 %. Also, verify that the front selector switch is in the (AUT) position. Check that contacts 313 and 317 are open. Verify that the power LED (Green) is On whilst the fault LED (RED) is off. Ensure that the Ready light on the ATS controller is a steady Green light. Verify presence of at least one green LED on the source supply available LED’s. Verify that the product is available with contacts 63A / 64A and 63B / 64B closed. Verify whether the problem is limited to the ATS controls + the motorisation module or just the ATS controls. To isolate the fault to the ATS controller or the complete unit, close contacts 312 with 317 whilst ensuring that 313 and 317 remain open. This will force the ATyS t int...
