St Switch Indicator Lights - Westinghouse ST SWITCH Manuel Utilisateur

OPERATION
WHEN UTILITY POWER COMES BACK ON:
After an outage when utility power returns the ST Switch will run a quick diagnostic to confirm there are no spikes
or flickering in the utility power before transferring input power back to utility. Once utility is returned the red utility
loss indicator light will turn off and the utility and generator power indicator lights will remain on. After power has
been transfered back to utility power, the ST Switch will allow the generator 45-50 seconds to cool down before
shutting it off. Once the generator has shut down the green generator power indicator light will turn off.
NOTE: If utility power is lost during the generator cool down phase the ST Switch will wait a couple of seconds and
transfer input power back to generator power until utility power is restored.
