3.10 Clock and Lock Configurations

The MX15 Series may optionally be equipped for clock and lock mode of operation. This mode is
a special form of Master/Auxiliary, which requires each chassis to have its controller. As such, it
is possible to create 1, 2, or 3 phase power systems using 2 to 3 MX15 chassis. For most single-
phase configurations, the normal multi-box mode of operation as described in section 3.7.5 is
recommended as it provides a single controller (and remote control interface).
In a clock and lock configuration, each unit has its own front panel controls (as well as individual
remote control interfaces) for operating the supply but the output frequency of the auxiliary
unit(s) (-LKS option) is synchronized (locked) to the Master MX unit (-LKM).
This mode of operation requires that one MX15 has the -LKM (Lock Master) option and one or
two MX units have the -LKS (Lock auxiliary) option.
3.10.1 Clock/Lock Configuration Settings
Clock and lock configuration settings for -LKM and -LKS equipped MX15's are set at the factory
at the time of shipment and cannot be changed. To check the configuration settings for an
MX15, select the OPTIONS screen. In the options screen, the CLOCK/LOCK entry determines if
the unit can be set as a Master or Auxiliary as follows:
CONFIGURATION Field

Note that the actual mode of operation of a Clock/Lock MX15-LKS auxiliary unit is determined by
the Clock mode set in the CONTROL menu. For clock and lock mode of operation, the CLOCK
field is set to EXT.
