In all other menus, the shuttle may be used to change parameter values
and settings.
Up/down arrow keys: A set of up and down arrow keys is used to move the cursor position in
all menus. This allows quick selection of the desired function or
parameter.
Function keys: ON/OFF key for output relay control.
PHASE This key is reserved for use on 3 phase AC power source and
has no function on the 751i/iX and 1501i/iX.
SET key will show output voltage and frequency setting.
MEAS key displays the measurement screens. Measure key will display
measurement values for selected phase or phase A if all three phases
are selected.
MENU key selects main menu.
BACK key is used to back up to previous screen.
Keypad: A numeric keypad contains numbers 0 through 9 as well as up and down
arrow keys, an Enter key, decimal point and polarity change (+/-) key.
The up and down arrow keys are used to move the cursor position in all
menus. This allows quick selection of the desired function or parameter.
Indicators and Display:
Status indicators: Status indicators inform the user of important power source conditions:
The Hi Range indicator is lit any time the unit is switched to the high
voltage range.
The Overtemp LED illuminates when internal heat sink temperatures are
too high.
The Overcurrent LED indicates that maximum programmed current limit
is being drawn at the output.
The Remote LED informs the user that the unit is under remote control.
The Output indicator is on when the power source output relays are
closed.
LCD graphics display: High contrast backlit LCD display. An adjustable viewing angle makes it
easy to read from all practical locations.

2.5 Special Features
Controller Features
Parallel Operation: Two i/iX chassis may be connected for parallel operation. The two
chassis must be connected using the system interface cable supplied
with the system.
Controller: Programmable controller front panel assembly.
Output Relay: Standard output relay feature to isolate power source from the load.
Output On/Off: The output relay can be used to quickly disconnect the load. A yellow
status indicator displays the status of the output relay.
External Trigger Output
or Function Strobe
An external TTL output is available which may be used to trigger other
equipment. The TTL output can be controlled by the transient
programming system. This requires the trigger mode to be set to EXT
(factory default). This can only be done over the computer interface using
the OUTP:TTLT:MODE TRIG command.
It can also be configured to generate an output pulse any time the
voltage, frequency, current limit or phase programming is updated. This
requires the trigger mode to be set to FSTR. This can only be done over
the computer interface using the OUTP:TTLT:MODE FSTR command.
This mode is compatible with the CI Lx/Ls Series.
The Trigger Output (Trig Out) / function strobe is an active low TTL signal
with a duration of no less than 400 us.
Clock and Lock Mode Enables two or more independent iX 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 3.10 for details on Clock and Lock mode.
Trigger Input A TTL input signal may be used as a trigger source for output changes
programmed on the AC power source transient system. This requires the
trigger source to be set to EXT. This can only be done via one of the
computer interfaces. An external trigger source may be used to control
the execution of output sequences that have been pre-programmed into
the power source transient system. Refer to i/iX Series Programming
Manual (6005-961) for details.
