| .Introduction
And Application |
| AMF
& Engine Control Relay Type –
AMR1 |
|
AMR1
has been designed for the control
of emergency and standby power systems.
It integrates the functions of engine
start / stop relay, engine and alternator
supervision and annunciator. The
relay has a user friendly MMI in
the form of a keypad and a LCD display.
The engine start / stop relay element
allows the automatic starting of
relay when power fails, automatic
stopping of the engine when mains
return and also the control and
interlocking of mains and DG Circuit
Breakers. It also includes delayed
supervision of oil pressure switch. |
