help to design schematic ?????

[nofky]

I have an 8 pin relay with 24v dc input on the coil of the relay. the pin configuration is as follows: 3-6 , 4-5 (3-6 normally connected on DT contact)outputs, 2-7 to coil, 1-8 are inputs to the dt contacts. I want to incorporate this relay into a schematic to allow a standby cranking battery to be charged by a SCR charger when the standby generator is not running and then switch to an engine driven alternator when the standby generator is running. any help would be appreciated.
