MomentaryRun Mode

For generators with MomentaryRun mode starting types (Type 11):

•Relay 1 (Run/Stop relay) can be used for two-wire configured generators.

•Relay 2 has no unique function in this configuration, but it is easiest to leave it doing the cranking so that another configuration is not required for it.

•Preheat will generally not be used in this configuration.

•The Preheat will never overlap the Crank Time.

•The “Delay” refers to the “Preheat to Crank Delay” and may be zero.

•Cranking will cease when the generator run signal goes high for the specified hold time or when the crank time has elapsed.
