3. Job Set-up

CAUTION: DO NOT USE THE TEACH-IN PROCEDURE TO CLEAR EPSU FAILURE MESSAGES. THE TEACH-IN PROCEDURE IS NOT A SYSTEM RESET. IT CAN CHANGE THE EMERGENCY LIGHT CONFIGURATION AND CAUSE HIDDEN FAILURES.

NOTE: The teach-in procedure of the EPSUs measures and keeps the load values that are related to each EPSU. The EPSU controller refers to these load values when the BITE test of the emergency lighting system operates. Thus, it is necessary that the emergency lights of the related EPSUs operate correctly during the teach-in procedure.
