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.
