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.
