Relay Timing
C–4 975-0307-01-01
GlowStop Mode
For generators with GlowStop mode starting types (Types 1, 2, 3, 6, 12):
• Relay 1 (Stop) and Relay 2 (Start) can be used with a common
ground for three-wire configured generators.
• The Preheat signal shows up on Relay 1 and also Relay 3 (if
enabled) so that Relay 1 can be used for both Preheat and Stop.
• If the ShutDown Bypass is enabled, the Preheat on Relay 1 will
remain high for the Crank Time and for the ShutDown Bypass period
after cranking.
• The Preheat on Relay 3 will only overlap the Crank Time and perform
ShutDown Bypass if Relay 3 is configured for Preheat with ShutDown
Bypass.
• 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.
