Precision Clock Pinning (Power Supply Replacement) - Honeywell LC13-510 Manual

2.9 PRECISION CLOCK PINNING (POWER SUPPLY REPLACEMENT)

The power supply has a pinning option for internal or external clock (see Figure 2-11). It
is pinned for internal clock unless the Precision Clock Source option is installed.
If you are replacing the power supply, check the pinning on the old supply and ensure that
the replacement is pinned the same.
