03055517 (full part number 03055517-03) is a base adapter board for the TwinStar (TH) placement heads used in the ASM SIPLACE SX/DX series. It serves as the electrical interface hub between the TH head and the gantry.
Core Functions
This board handles power distribution and status monitoring for the TH head. Onboard LEDs provide direct indication of the "PowerFail" status for various voltage rails (1.5V, 3.3V, 5V, 15V, and 24V), as well as the operational or error status of the HCU1 and HCU2 units. Two 7-segment displays, labeled V12 and V2, show the status codes for the respective HCUs, while switch S1.2 (on DIP switch S1) is used to reset HCU2.
Compatibility Note
This board is designed exclusively for TwinStar (TH) heads. Within the spare parts system, it is typically categorized as a component of the "Head adapter HCU for TwinHead" (03065969-xx) assembly and is used in conjunction with two HCU modules.
