UTILITY Menus
Figure 5-17: UTILITY Menus
The UTILITY menus provide access to less frequently used setup items. There is no connection between
the various entries in the UTILITY menu other than there is no other logical place to put them. The
following entries can be found in the UTILITY menu:
Entry Description
UTILITY 1
GPIB/RS232 SETUP
This entry provides access to the setup parameters for either the IEEE-
488, RS232, USB or LAN interface. All parameters are saved in non-
volatile memory so there is rarely a need to change these values.
VOLT/CURR CONTROL
The voltage and current control menu can be used to select the current
limit method, the voltage sense source.
The standard available voltage range pairs are 150 Vac and 300 Vac in
AC mode or 200 Vdc and 400 Vdc in DC mode.
The two current limit choices are Constant Voltage and Constant
Current. Constant Voltage mode will maintain the set voltage at the
output until the load current exceeds the current limit setting at which
time the voltage will be dropped to zero. This effectively shuts off the
AC source output in case of an overload condition. This mode has
user programmable trip delay, which is located in the same menu.
Constant Current mode will maintain the load current at the maximum
level set by the current limit value, even if the maximum power level
is exceeded. This is done by reducing the voltage as needed. As such,
the voltage will be reduced from the set level down to zero depending
on the load requirement. This mode is useful for starting up motor or
capacitor loads that may require a high inrush current. This mode also
has a user programmable trip delay.
Voltage sensing for regulation and measurement can be selected for
internal or external. External voltage sensing can compensate for
voltage drops caused by load cable impedance. To achieve the best
output regulation select external sense and connect the voltage sense
wires at the load.
INITIAL SETUP
The initial setup menu can be used to determine the AC source
settings at power up. CAUTION: The initial setup can be used to
power up the AC source with the output on and a high voltage present
at the output. For normal situations, this is not recommended due to
the potential danger to operators. It is recommended that the initial
voltage be set low and/or the output relay be programmed to OFF for
most situations.
LIMIT SETUP
The Limit menu shows the frequency, voltage and current limit
capabilities of the AC source. Any attempt to program the output
beyond these limits will result in a “-222 Data Out of Range error”.
Note that these limits are hardware determined and cannot be changed
by the user. They are shown for reference only.
