3.3.3 PROGRAMMING VOLTAGE OR CURRENT AND ASSOCIATED PROTECT LIMITS
From the power-up screen the settable voltage/current parameters are displayed at the bottom
of the LCD above the HELP message (see Figure 3-3). Use
Y
or
U
to highlight the main or
protect channel. (For BOP protect limits refer to PAR. 3.3.4.2 and for external limits see PAR.
3.3.4.3.)
1. To verify that the unit is configured for internal references press
$
from the power-up
screen and verify that Reference Input and Protection Limit are set to Internal, and External
Mode is set to Disable. If necessary to change a setting, use
Y
or
U
to highlight the
parameter, and press
!
to modify. Highlight the desired selection and press
$
to save,
then press
$
to save for power-up or
%
to exit. If analog programming is desired, refer to
PAR. 3.4.
2. Verify that the load has been configured properly to ensure that the unit behaves as
expected when the output is off (see PAR. 3.3.6 for details).
3. Press MODE key to select the main channel (VOLTAGE or CURRENT); the associated
PROTECT channel is automatically selected and displayed.
4. Set the output on or off as desired using the STANDBY key. The output is off (disabled)
when the STANDBY indicator is lit, on (enabled) when not lit.
5. Use
Y
or
U
to highlight the main channel. There are two ways to program the output in
local mode. These methods can be used either when the output is disabled (STANDBY indi-
cator lit) or enabled.:
CAUTION: WHEN THE ADJUST CONTROL IS ROTATED, THE ACTIVE PARAMETER IS
IMMEDIATELY EFFECTIVE IF THE OUTPUT IS ENABLED (ON = STANDBY
INDICATOR NOT LIT). THE VOLTAGE/CURRENT APPLIED TO THE LOAD
CHANGES AS THE ADJUST CONTROL IS ROTATED.
a. Use the ADJUST control to increase or decrease the main channel setting (e.g., volt-
age when the unit is in voltage mode). Start with the most significant digit of the desired
value, then use
T
to highlight the next digit. For fine adjustment press the ADJUST
control in while rotating the knob to modify the least significant digit.
b. Enter the desired value on the keypad using the number keys. For example, to program
the BOP to 75.8V, press the following keys in order
75.8
then press ENTER. For
fine adjustment use
Y
, and
U
to modify the least significant digit. To correct the entry
before activation press the CLEAR key to set the value to zero and start over. When the
desired value is displayed, press ENTER. This causes the new value to appear at the
output and be applied to the load if the output is enabled.
NOTE: The value entered for the main channel and the protect channel is automatically pre-
vented from exceeding the present maximum software limit (see PAR. 3.3.4).
6. To program the corresponding Protect channel, press
Y
or
U
as necessary to highlight the
Protect channel. Then set the value using either of the two methods described above. If the
Protect Entry setting (see PAR. 3.3.3.1) is set to Independent, separate entries for the posi-
tive and negative protect channel are possible. Otherwise the value entered is applied to
both positive and negative protect channels.
