3.5.8 Crank Disconnect and Over-Speed Pot Adjustment
From the factory, the
Crank disconnect
is set to 20 Hz in low-speed mode and 300 Hz in high-speed mode.
One turn gives approximately 6.4 Hz in low speed and approximately 205 Hz in high speed.
From the factory, the
Over-speed is set to 69 Hz in low-speed mode and 1080 Hz in high-speed mode. One turn
gives approximately 13 Hz in low speed and approximately 410 Hz in high speed.
The best method to determine the proper Crank disconnect and Over-speed setpoints is to use a signal
generator (also known as a function generator). If you do not have one, you can adjust the pots knowing the
factory defaults and the Hz/turn numbers provided above.
3.5.9 Loss of Speed (During Cranking)
In the event there is a loss of speed, while cranking or running, the unit will shut down, and this is indicated by a
flashing Over-speed LED . Loss of speed is defined as no speed signal for at least 3 seconds . Loss of speed
begins 3 seconds into the crank cycle.
The
Loss of Speed While Cranking portion can be disabled via DIP switch 9. When the DIP switch is in the UP
or ON position, the Loss of Speed While Cranking function is enabled. When the DIP switch is in the DOWN or
OFF position, the Loss of Speed While Cranking function is disabled.
Note: The Loss of Speed feature is maintained during all running conditions.
Note: If unit is configured for Generator Output, there may not be enough residual voltage during cranking
for this feature. It is recommended to disable this feature.
The following values are minimal recommended voltages for speed signal:
20 Hz – 0.075 V (75 mV)
60 Hz – 0.6V (600 mV)
4500 Hz – 0.8V (800 mV)
