10. Controller (AMF 25)
The generator controller AMF 25 (10) is a microprocessor ‐ based control
unit containing all of the necessary functions for the protection and
control of the generator. It also monitors the three ‐ phase AC voltage &
current. The unit is equipped with a liquid crystal display, to present all
values and alarms.
11. Earth Leakage Relay (ELR)
The generator is equipped with an earth leakage relay (11). There are two
different types of relays, the standard configuration is RH99P , which is
panel mounted. The other is RH99M , din rail mounted, located in the
control cabinet.
12. Mains RCD Test Point Pushbutton
Depressing the Mains RCD Test Point Pushbutton (12) allows power to the
RCD Test Point (13) .
13. RCD Test Point
The RCD Test Point (13) is used to test the earth leakage protection
function. When an earth leakage greater than the adjustable ELR’s
setpoint occurs, the main circuit breaker (17) will shunt trip.
14. Test Point Isolator (2A,2P)
The lockable two pole RCD Test Point Isolator (2A) (14) is located on the
control panel and protects the RCD Test Point (13).
15. Outlets Isolator (50A 2P)
The lockable two pole Outlet Isolator (50A) (15) is located alongside the
main isolator on the control panel. When the electric current exceeds
50A, it will automatically interrupt the power to all outlets.
16. Shunt Trip
When an earth leakage fault greater than the adjustable ELR’s setpoint
occurs, the Shunt Trip (16) will open the Main Isolator (17) and interrupt
all power from the load side of breaker.
Note: The generator will still supply power to the line side of breaker.
