2.12.4 Remove from Parallel Operation.
If necessary to move a generator set which has been operating in parallel
with another generator set, shut down remaining generator set connected to
the load prior to removing load cables or ground. Failure to comply can
cause injury or death to personnel by electrocution.
Prior to removal of one generator set from parallel operation, make sure
load does not exceed full load rating of generator set remaining on the line.
Failure to comply can cause damage to generator set still on line.
a. Momentarily hold AC CIRCUIT INTERRUPT switch (15, Figure 2-8) in OPEN position until
CONTACTOR POSITION on CIM display screen reads OPEN.
b. Shut down generator set, paragraph 2.11.2.
2.13.1 Description and Operating Instructions.
a. The DCS provides the ability to control and monitor the generator set from a remote location using an
IBM-compatible personal computer (PC). Minimum requirements for that computer are: a 486
processor, RS485 serial card, 3.5" Floppy Drive and /or CD ROM drive, Windows 95 operating
system, and a mouse. (Note: Multiple RS 485 serial cards are available to use. Recommend an
internally installed RS 485 card be used for desktop PCs and a PCMCIA card be used for laptop
b. Remote instrument monitoring allows the operator to observe metering and protective device status. To
start and run the generator set the operator must follow the operating procedures described in paragraph
2.11. When connected, the remote display functions are independent of the onboard CIM display.
That is, the remote display includes the same controls and indicators as the CIM display (Figure 2-2),
but with added controls as indicated in step c below. Switching modes on the remote display screen
does not affect the screen mode displayed on the CIM.
c. Additional switching controls on the remote screen allow the operator to control four functions of the
remote PC and generator set from the remote location. The SHUTDOWN COMPUTER EXIT button
(1, Figure 2-11) is used to shut down the remote operation shutdown and return control of the generator
set to the DCS onboard controls. The DISPLAY MODE FULL/MAIN button (2, Figure 2-11) allows
the operator to toggle between display modes on the remote computer like the same button does on the
CIM display screen. The BATTLESHORT SEL. SW. ON/OFF button (3, Figure.2-11) allows the
remote operator to remotely activate and deactivate the generator set's battle short function. The
ENGINE CONTROL RUN/STOP button (4, Figure 2-11) allows the operator to stop the generator set
engine from the remote PC.
d. A cable links the remote PC to the generator set via the COMMUNICATION RECEPTACLE (J3) (1,
Figure 1-30). COMMUNICATION RECEPTACLE (J3) internally connects to (J21) (Figure 2-3), of
the I/O interface module via generator set wiring. COMMUNICATION RECEPTACLE (J3) is a nine
pin environmentally sealed connector. One end of the remote cable hooks to COMMUNICATION
RECEPTACLE (J3), the other end terminates at the RS485 serial card installed in the remote PC.
