CAUTION:
Master/slave operation is intended as an extension of the current and power
capabilities when testing a single output power source. The slave units
cannot be connected to a second source or output. This will cause damage
to any or all of the loads in the system.
DANGER:
Loads are not to be connected in series
In systems with parallel loads, the system fault indicator will illuminate if any load in the
system has a fault. The DC-ON indicator illuminates when the load is active. If a load is in the
slave mode, the indicator will illuminate when the slave is enabled. When the master is turned
on, the slave indicator will flash continuously.
Short Circuit Feature
In order to test current limited power sources that require short circuit testing, the XBL
provides a Short Circuit feature. When this feature is activated it applies a simulated short
circuit across the device being tested.
The load simulates a short circuit by driving all of its power semiconductors hard into a
saturated on state. Caution must be exercised to only use this feature when testing current
limited sources as the Power Limit and Current Limit are disabled while it is activated. A
Saturation fault will indicate while the short is activated.
Programmable Under Voltage (UV) remains active while the Short Circuit feature is used.
These will disconnect the load from the device under test if they are not turned off or set to zero
first..
This feature is activated when the “Short” button on the front panel is depressed. It can also be
remotely programmed using the SHORT ON/OFF command. Since a short circuit could cause
damage to the load or the device under test in many applications, front panel use of this feature
is normally locked out. This feature must first be enabled through the menu to use it from the
front panel.
CAUTION:
This function is intended for use only when testing current limited power
sources. Use of the Short Circuit feature with power sources which do not
limit their current to values within the load’s ratings could result in damage
to the load, damage to the device under test, FIRE or EXPLOSION.
Note:
Please refer to Table F for a list of major and minor fault indicators.
MEM — Memory Recall Locations
The configuration of the load may be stored in 6 settable memory locations labeled 1 thru 6. To
recall a memory location, press the MEM key on the front panel. Enter the numeric location
number, then press ENTER. When using the RS 232, Ethernet or IEEE-488 bus the setup can be
stored with the MS command and recalled with the MR command. Setting the memory can also
be accomplished throught the front panel menu.
