1。標(biāo)記并斷開DECS-100的所有接線。確保絕緣接線端子，以防止短路。
2.啟動(dòng)原動(dòng)機(jī)并執(zhí)行所有發(fā)動(dòng)機(jī)調(diào)速器調(diào)整。
3.完成所有初始調(diào)速器調(diào)整后，關(guān)閉原動(dòng)機(jī)。
Communication Port
The RS-232 port on the rear panel uses a DB-9
female connector. Figure 4-4 Illustrates the pin
assignments of the communication port and
Table 4-4 Identifies the RS-232 connector pin
functions. A standard communication cable
terminated with a DB-9 male connector is used
for PC interface with the DECS-100 as shown in
Figure 4-5. DECS-100 Connections for Typical Applications
Figures 4-6 through 4-10 illustrate typical applications using the DECS-100. Figure 4-6 shows an
application where DECS-100 operating power is derived from a permanent magnet generator (PMG) and
three-phase voltage sensing is applied to the DECS-100. Figure 4-7 shows another PMG application but
with single-phase voltage sensing. Figure 4-8 shows an application where DECS-100 operating power is
derived from the generator output (shunt application) and three-phase voltage sensing is applied to the
DECS-100. Figure 4-9 shows another shunt application but with single-phase sensing. Figure 4-10 shows
a DECS-100 powered by single-phase station power in a three-phase sensing application.
Figure 4-11 shows a typical connection diagram for two paralleled generators operating in cross-current
compensation (reactive differential) mode. The resistors shown have a value of 0.1 ohms. This is a typical
value that can be used to set the burden. (Ensure that the resistor power rating is adequate for the
installation.) The following paragraphs describe the mounting and wiring requirements for a CE (European
Community) compliant installation.
Mounting
The DECS-100 must be mounted inside a grounded, metal enclosure (conduit box). An access panel
should cover the opening for the front panel display.
Wiring
Wiring connected to the terminals listed below must be shielded. Each shield should be terminated to
ground on the outside of the conduit box.
? Current sensing terminals CT1 and CT2
? Relay output terminals AL1 and AL2
? Var/Power Factor control contact input terminals 52J and 52K
? Parallel generator compensation terminals 52L and 52M
? Raise and lower contact input terminals 6U, 6D, and 7
? Accessory input voltage terminals A and B
? Voltage matching contact input terminals VM and VMC 1. Tag and disconnect all wiring to the DECS-100. Be sure to insulate the wire terminals to prevent a
short circuit.
2. Start the prime mover and perform all engine governor adjustments.
3. After all initial governor adjustments have been made, shut down the prime mover.
