4. Current limits are recommended to be greater than the
maximum current required for the load by 10% of the
rated current of the unit (e.g., for a 6A BOP and a load
that requires 3A, set current limits to ±3.6A).
If specific ± current limits are not needed, use a screw-
driver to adjust the + I CURRENT LIMIT potentiome-
ter to full clockwise position and - I CURRENT LIMIT
potentiometer to full counterclockwise position.
If specific ±current limits are needed, proceed as fol-
lows:
a. Turn VOLTAGE CONTROL fully counterclockwise.
Use a screwdriver to adjust the – I CURRENT
LIMIT potentiometer as desired (recommended to
be 10% greater than the maximum negative current
required for the load), monitoring the CURRENT
meter for the correct limiting value.
b. Turn VOLTAGE CONTROL fully clockwise. Use a
screwdriver to adjust the + I CURRENT LIMIT
potentiometer as desired (recommended to be
10% greater than the maximum positive current
required for the load) monitoring the CURRENT
meter for the correct limiting value.
c. Set the VOLTAGE CONTROL switch to OFF. Set a-
c POWER switch/circuit breaker to OFF, then
remove the short circuit from the output but leave
the load disconnected.
5. Set the BOP MODE switch to CURRENT, CURRENT
CONTROL switch to ON and set a-c POWER switch/
circuit breaker to ON.
6. Adjust the ± V VOLTAGE LIMIT potentiometers to the
required output (compliance) values. Proceed as fol-
lows:
a. Turn CURRENT CONTROL fully counterclockwise.
Use a screwdriver to adjust the – V VOLTAGE
LIMIT potentiometer as desired.
b. Turn CURRENT CONTROL fully clockwise. Use a
screwdriver to adjust the + V VOLTAGE LIMIT
potentiometer as desired.
c. Set a-c POWER switch/circuit breaker to OFF, then
connect a short circuit across the OUTPUT and
COMMON terminals.
d. Set a-c POWER switch/circuit breaker to ON and
use the CURRENT CONTRol to adjust the output
current to zero.
e. Set a-c POWER switch/circuit breaker to OFF and
remove short across OUTPUT and COMMON ter-
minals.
7. Connect the load to the BOP OUTPUT and COMMON
terminals.
8. Set a-c POWER switch/circuit breaker to ON and use
the CURRENT CONTROL to adjust output current
through the load to the required value.
