Relay Timing
C–4 975-0082-01-01
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.
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.
