If External mode was saved, the protection setting is followed by C, indicating that the mode
(voltage or current is Conditioned by the external signal applied to pin 2 of the Analog I/O Port
(see Table 2-10).
If the protection setting is followed by a minus sign (–) it indicates that the negative protection
value (displayed) is set larger (absolute value) than the positive protection value (not shown on
the list). Similarly, if the protection setting is followed by a plus sign (+) it indicates that the posi-
tive protection value (displayed) is set larger than the negative protection value (not shown on
the list).
If Main channel reference was saved as External, EXT is listed under the Main heading. In this
case the main channel reference uses the external voltage applied to pin 11 of the Analog I/O
Input Port (see Table 2-10).
If Protection type was saved as External, EXT is listed under the Prot heading. In this case the
protection settings are determined by the levels applied to the appropriate pins of the Analog I/O
Input Port (see Table 2-10). If the main channel is voltage, the protection settings are deter-
mined by pin 5 (negative current protection) and pin 13 (positive current protection). If the main
channel is current, the protection settings are determined by pin 6 (negative voltage protection)
and pin 14 (positive voltage protection).
3.3.8.2 VIEWING SAVED SETTINGS
1. Pressing
!
from the power-up screen displays the Saved Setups screen (Figure 3-8) con-
sisting of a list of locations 1 through 20 arranged in two columns of 10 rows. Use
T
and
R
keys to display additional columns. NOTE: Use the number keys as a shortcut, e.g., press-
ing 4 immediately highlights location 41, showing the column with locations 41 through 50.
2. Use the
U
and
Y
keys to highlight the desired memory location; When the desired location
is highlighted, press
!
. The details of the parameters listed in Table 3-8 are displayed.
3.3.8.3 SAVING SETTINGS AND ERASING OR MODIFYING PREVIOUSLY SAVED SETTINGS
1. Press

from the power-up screen to enter the Saved Setups screen (Figure 3-8).
PROTECTION
MODE
INTERNAL
EXTERNAL
LESSER LIMIT
INTERNAL - Allows limits to be controlled by POSITIVE and NEGATIVE values.
EXTERNAL: Allows limits to be controlled by analog signals applied to the analog
port (see PAR. 3.4.4).
LESSER LIMIT: Allows protect limit to be automatically selected from either 1) the
external analog voltage applied to the Analog I/O port or 2) the value set in the
POSITIVE and NEGATIVE fields. Whichever limit has a lower absolute value
(closest to zero) has effect (see PAR. 3.4.4).
POSITIVE nn.nnn or
nnn.nnn
This is the positive value for Voltage protect if CURRENT mode is selected, or the
positive value for Current protect if VOLTAGE mode is selected. If EXTERNAL
mode is selected, this field is not accessible.
NEGATIVE nn.nnn or
nnn.nnn
This is the negative value for Voltage protect if CURRENT mode is selected, or the
negative value for Current protect if VOLTAGE mode is selected. If EXTERNAL
mode is selected, this field is not accessible.
OUTPUT OFF
ON
OFF - Output disabled. The behavior of the unit when output is disabled depends
on the LOAD TYPE setting (see PAR.3.3.6).
ON - Output enabled.
