NOTE:
The MT-30 incorporates safety features related to load configuration.
If at any time the load connections do not match the selected
configuration (e.g., due to a connector being pulled from the unit
accidentally or a load connection being changed inappropriately), the
unit will automatically disconnect the output terminals of the applicable
DC Converter.
4.8 Adjusting Operating Limits
The next step is adjusting and verifying the voltage, current, and power limits of the
converter.
Once the system power is on, the system is operating properly, and the load connected
to the Cam Lock(s) connectors, the DC Converter will prompt the user to set limits by
flashing the
mode
buttons.
To set the limits push the
UPPER or LOWER LIMITS button. The corresponding
UPPER or LOWER LIMITS
will be displayed on the front panel in the VOLTAGE,
CURRENT, and POWER
displays. While holding the LIMITS button down, increase
or decrease the limits using the Up Arrow (
×
) or Down Arrow (
Ø
) buttons,
respectively, next to the appropriate display. The DC Converter will not allow the user
to move to the next step until both upper and lower limits have been examined.
If you have attached two loads and the unit is in
Independent
configuration, you will
need to repeat this procedure for both sides (Load A and Load B). In this situation, you
may choose to set limits for one side first and begin a test on that load before returning
to set the operating limits for the other side.
Once the operating limits have been set (or at least checked), the
Mode
buttons will
flash on the front panel (VOLTAGE, CURRENT, POWER and STANDBY). Again,
these buttons may flash on either side (A or B) or on both sides, depending on the
configuration that has been chosen.
4.9 Selecting Local or Remote Operation
Once the load has been connected, the load configuration has been chosen, and the
operating limits have been set, the MT-30 is ready to run. At this point, the unit is in
Local/Independent mode operation by default. If ROS is running Remote Operation of
each channel, it can be initiated; otherwise, the unit must be operated in Local mode via
the front panel controls.
If local operation is planned, no further action is required before selecting a control
mode (i.e., Voltage, Current, or Power Control). Local operation is described further
below.
4.10 Local Operation
In local operation, all control and adjustment is done at the front panel of the DC
Converter. A control mode must be selected to start a test. After the test has begun, the
control setting may be adjusted and the control mode may be changed while running the
