StartStop Mode
For generators with StartStop mode starting types (Types 4, 5, 9, 10):
Relay 1 (Stop) and Relay 2 (Start) can be used with a common
ground for three-wire configured generators.
If Relay 3 is configured for preheat, the signal only shows up on
Relay 3.
The Preheat on Relay 3 will not overlap the Crank Time if ShutDown
Bypass is not enabled.
If the ShutDown Bypass is enabled, the Preheat on Relay 3 will
remain high for the Crank Time and for the ShutDown Bypass period
after cranking.
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.
To get the ShutDown Bypass on Relay 3 with no preheat, Relay 3
must be configured for Preheat with ShutDown Bypass and have the
Preheat time set to zero.
StartStop mode is essentially the same as GlowStop mode with no
preheat on Relay 1.
