TP-6200 10/1240 Section 2 Operation
OverCurrent VR Shutdown. The lamp illuminates and
the unit shuts down when the controller detects an
overcurrentfault with voltage restraint. The local display
showssd over current pr. (Paralleling applications only.)
Overfrequency. The lamp illuminates and the unit
shuts down when the frequency is above the
overfrequency setting. The local display shows
overfrequency. See Figure 2-3.

Overpower. The lamp illuminates and the unit shuts
downwhen the controller detects a fault in the paralleling
system. The shutdown is set at 102% for standby and
112% for prime power applications. The local display
shows over power. (Paralleling applications only.)
Overspeed. The lamp illuminates and the unit shuts
down immediately when the governed frequency on 50
and 60 Hz models exceeds the overspeed setting for
0.25 seconds. Thelocal display shows overspeed. See
Figure 2-4 for overspeed specs.

Overvoltage. The lamp illuminates and the unit shuts
down when the voltage exceeds the overvoltagesetting
for the time delay period. The local display shows
overvoltage. Overvoltage specifications follow. See
Figure 2-5.
Note: Overvoltage can damage sensitive equipment in
less than one second. Install separate
overvoltage protection on online equipment
requiring faster than 2-second shutdown.

Reverse Power. The lamp illuminates and the unit
shutsdown when the controller detects a reverse power
condition. The reverse power relay senses AC power
flow into the generator set. If the generator set is being
feed power or being ”motored” by another generatorset
or the utility, the reverse power relay senses this AC
power flow and opens the generator set circuit breaker.
The local display shows sd reverse power. (Paralleling
applications only.)
Underfrequency. The lamp illuminates and the unit
shuts down when the frequency falls below the
underfrequency setting. The local display shows
underfrequency. See Figure 2-6.
