FieldsTitleWhat are contacts 209 and 210 for?URL NameWhat-are-contacts-209-and-210-forContentPublic AnswerThese wires are used for alarms relating to generator and engine performance that appear on the controller and in the Mobile Link application (if used). The controller is equipped with a common alarm relay providing contacts for an optional customer-supplied external alarm indicator. The common alarm relay is normally open until an alarm occurs, triggering the relay to close contacts.Terminals for the common alarm relay are provided in the wiring harness near the controller plug (wires 209 and 210).For example: If the generator owner has an existing alarm system in their home they can tie it into the generator on wires 209 and 210. These contacts will close if there is a stop alarm present on the control board, notifying the user of an issue. The contacts do not close if the unit is turned OFF or if a maintenance reminder is present. The ratings for these contacts are 200 mA at 12VDC and are for resistive loads only.
