Approved relays for 12 or 24VDC system operation are as follows: •... - Page 10 10 of 28 Speed. Options: Generator Output (L-Version) or Mag Pickup (H Version) 9 , 10 Generator Output (L-Version) Speed Signal Input for Crank Disconnect, Engine Run, and Overspeed sensing. 300VAC max input voltage. Speed sensing input terminals (#9, #10) do not have polarity sensitivity therefore the AC generator output leads can be connected in any polarity configuration.
- Page 11 11 of 28 Low Battery Output closes to +12/24VDC on Low Battery Condition. When a low battery condition is detected this output turns on immediately. When the low battery condition is removed this output remains on for 5s before turning off. Engine Run Output closes to +12/24VDC on Engine Run Condition.

When the power to the controller is turned off and then back on again without waiting 10 seconds to clear the memory, a loss of speed will may be indicated by the GSC300 (if controller is in AUTO mode and start signal is activated) because the controller remains in run mode and senses that the generator has stopped. -

Implementing Automatic Start on Low Battery Procedure The customer is responsible for determining the adequacy of this for their application. Cattron does not guarantee this procedure will work in all applications. 1. Connect the low battery output to the start/stop input on the GSC300. When the GSC300 generates a low battery warning this will trigger the remote start and start the generator. -
