Using the available soft keys set the PLC Remote to
ON
and Dual Test to
ON
.
The rear panel remote interface is reconfigured to allow two test switches instead
of the standard reset and test inputs. The two test switches have to be pressed
within 0.5 seconds to activate the test process. The two test switches must
remain closed to continue the test. If either of the test switches is released, the
process will be shut down immediately. The functions of the Test and Reset
switches on the front panel will be disabled if the dual test switches are enabled.
When the Dual Test parameter is turned OFF, the Test and Reset switches on
the front and rear panel behave the same as the standard instrument, and are
controlled by the PLC Remote On/Off selection.
04 Omnia to APT 3 Memory (Models 8206, 8207, 8256, 8257) (Discontinued)
With this option installed, the PLC remote signal output has been reconfigured to
provide a 2-Bit digital control signal that is menu selectable from the Run Test or
LCT parameter screen. In this configuration, the PLC remote signal output may
be used to control a compatible Associated Power Technologies (APT) AC power
source.
This option is provided with a cable which is designed to interconnect the OMNIA
II PLC output to the APT power source Remote I/O input. This cable, part
number 38774, is custom and can only be purchased from Associated Research.
When using this option with an APT power source, be sure to power up the
OMNIA II first and then power up the AC power source. When powering down
the instruments, power down the AC power source first and then power down the
OMNIA II. The OMNIA II is in an undetermined state without power and may
cause inadvertent memory activation of the APT power source. If you would like
to operate the APT power source independently of the OMNIA II, either
disconnect the interface cable or disable the PLC remote on the APT power
source.
The Remote Memories send signals are provided by two normally open internal
relays. These are normally open free contacts and will not provide any voltage or
current. The ratings of the contacts are 1A / 125 VAC ( 0.5ADC ).
With this option, a new soft key selection will appear on the Run Test parameter
or LCT parameter screen. In the LCT parameter screen it will be necessary for
you to press the “More” soft key to access the PLC control parameter. The new
soft key, called PLC Control will toggle between M1, M2, and M3 when pressed.
Setting the PLC control selection to M1, M2, and M3 will create different digital
states at Bit 0 and Bit 1 of the PLC Remote Signal Output (refer to the PLC
Signal Output drawing below). The different states are described in the truth table
below.
The “Not used” state is undefined and cannot be programmed for use.
