Zusammenfassung: | PURPOSE: To take more parameters and datum into consideration by driving a grow plug with discriminating each grow heating process which is separated from each other. CONSTITUTION: Data languages are transmitted from an engine control device MS to an interface 1 in series to drive a grow plug. A driver-circuit 2 transmitted with data languages through a microprocessor MP practices individual grow plug process by operating two relaies R1, R2. In the occasion, the relay R1 is used as a main relay which supplies an electric current and becomes on continuously when the grow plug is driven. And the relay R2 is used to shorten pre-resistance which is connected with a front step of the grow plug and distinguishes the grow heating process by changing on-time according to the data languages. Thereby, selections of parameters and datum used when the grow plug is driven are not limited. |
