4.2.5 CONTROL Menus
Figure 4-6: CONTROL Menus
The CONTROL menu is shown in Figure 4-6 and can be reached by selecting the Menu key, selecting
the CONTROL entry using the DOWN cursor key and then pressing the Enter key.
The CONTROL menu is used to change secondary output parameters. The following choices are
available in the CONTROL menus:
ENTRY DESCRIPTION
SENSE Selects internal or external (remote) voltage sense mode. If INT is
selected, the voltage is sensed at the output terminal block. If EXT is
selected, the voltage is sensed at the external sense connector. If
external sense is selected, care must be taken to connect the
external sense lines at the load. For sense leads longer than 1
meter, twisted pairs should be used.
SYNC Selects the external sync mode if available. Default is internal sync,
which means a free running time base. The time base can be
synchronized to an external sync signal depending on installed
options (-EXS option).
CLOCK Selects internal or external clock source. The i/iX Series controller
uses an open-air crystal time base with an accuracy of 100 ppm. The
external clock mode is used to support the
–LKS option. For use as
an auxiliary unit in a clock and lock system, this field must be set to
EXT. A unit with
–LKS option can be used stand-alone if needed by
setting the INT clock mode.
The same EXT setting is required to use the
–RPF (remote
programming frequency) analog input for frequency programming if
the
–RPF option is installed.
INT Default, internal clock.
EXT Auxiliary unit (-LKS) driven by master (-LKM) clock
input.
Note: When selecting EXT mode, make sure the
Clock and Lock BNC cables are connected to the
Master (-LKM) unit. If not, there will be no output on
the
–LKS unit. See section 3.10 for connection
information.
MODE Power on clock mode. The following two modes can be selected.
