AS3000 Model
■
Auto crank disconnect
■
Multi-attempt starting
■
Fault warning and shutdown
■
Reduced panel wiring
■
Simple set set-up
Description
The AS3000 provides automatic start up, fault monitoring and shutdown control for engine driven applications. The unique two-module design, with a single interconnecting lead, gives reduced panel wiring and installation. This simple, compact unit is ideally suited to small engine and generator panels.
Key features
• Multi-attempt cranking with auto crank disconnect
• Automatic or manual modes, selected by front facia pushbuttons. Control inputs for optional security keyswitch.
• User inteface module: front of panel mounted,
92mm square DIN cut-out. Environmental sealing to IP65
• Panel interface module: DIN rail mounted
PCB tray.
• Fault shutdown and indication system. Low oil pressure, high coolant temperature and auxiliary inputs are fitted to both modules, allowing use with engine mounted fault switches or panel mounted SWICHGAGE ® units.
• Speed sensing (auto crank disconnect and overspeed shutdown) is via magnetic pickup, generator AC or remote contact. Speed calibration is automatic and adjustment free.
• Mains charger/charge alternator fail warning LED.
• Easy setup of operating options using circuit board links.
• Generator AC Hz meter output, 0 – 5V.
