FCS Series II
2.6.3 -LKM and -LKS Options - Supplemental Specifications
The Clock and Lock option enables two independent FCS power systems to be phase synchronized to
each other. One system (-LKM) acts as the master, the other(s) (-LKS) as auxiliaries. The –LKS units are
synced to the –LKM unit. Refer to section 3.9 for details on Clock and Lock mode. Note that the maximum
number of auxiliary units (-LKS) per master (-LKM) is one. No T connectors are allowed to increase the
number of auxiliary units as this may cause reflections on the clock and lock signals.
Note: It is not possible to mix Series I FCS units and Series II FCS units in a clock and
lock configuration. Both models must be of the same series.
The following supplemental specifications apply when the Ls is configured with the Clock and Lock option.
(-LKM or –LKS).
