10 Wiring the StarPac 3 System
10.1 General
All electrical connections must be done according to local and industry electrical codes. Flowserve recommends a
shielded cable be used for the RS-485 command signal wire (e.g., Belden 9841 or equivalent).
When connecting multiple StarPac 3 units, a parallel daisy-chain wiring pattern is used. Connect unit‘s branch lines
to main line, keeping branch lines as short as possible. The total length of wiring should not exceed 4,000 feet (1,200
meters) without use of repeaters.
Avoid devices producing electrical ‘noise’ while installing the cable.
CAUTION: The following procedure should be performed on the bench or with the unit isolated so that unex-
pected valve stroking will not adversely affect the process.
WARNING: The following procedures may cause the valve to stroke, causing pressures and temperatures to
vary from their norms. Notify appropriate personnel that the valve may stroke unexpectedly. It is recommended that the
system be isolated from the process, if installed in line.
WARNING: Cable entry temperature may exceed 70
0
C. Therefore, select appropriate rated cable.
