Prime power (RPR) is the normal output continuously available, where the average load (variable) does not exceed 70%
of the prime power rating during an operating period of 250 hours. The total operating time at 100% prime power must
not exceed 500 hours per year.A 10% overload is available for a maximum of 1 hour in 12 hours of operation and must
not exceed a total of 25 hours per year.
Standby Power (LTP) is the maximum output available (at variable load), for up to 200 hours per year. The average load
(variable) must not exceed 80% of the standby power rating, with less than 25 hours per year at the full standby rating.
No overload is available. The genset must not operate, at standby rating, in parallel with the public utility under any
circumstances.

SINGLE SET GEN-SET OPERATION
Diesel genset integrated controllers for single engine control in
manual and remote start applications, featuring full gen-set
monitoring and protection. In other words making them ideal for
primer mover applications.
Genset integrated controllers for gen-sets operating in single
standby mode. They meet all possible requirements for AMF
applications,including modem control, user configuration and full
gen-set monitoring and protection.AMF models enable the
combination of manual and remote start application with auto
mains fail function.
