Appendix B: Relay Timing

RunMode

For generators with RunMode starting types (Types 7, 8, and 14):

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

•Relay 1 (RunStop) and Relay 2 (Start) can be used with a common ground for three-wire configured generators.

•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.
