2.6 Special Features
Controller Features
Controller:
Programmable controller front panel assembly.
Mode
Available single-phase mode option (-MODE) allows the output of all
three amplifiers to be combined on phase A output terminal. No external
switching or reconnection to the load is required.
Output Relay:
Standard output relay feature to isolate power source from the load.
Each phase and the neutral (common) output is disconnected when the
output relay opens.
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 3.9 for details on Clock and Lock mode.
Clock and Lock option is not available with the FC option
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.
