BHK-MG (OPR) 022014

NOTE: If using two different BHK models, e.g., 500-0.4MG and 1000-0.2MG, unit A must be

the one with the lower current capacity: 1000-0.2MG

a. Program IsetA to the current limit for the power assembly.

b. Program VsetA to:

(to nearest volt) where:

• Eo is the output voltage of the power assembly,

• EomaxA is the rated maximum output voltage for unit A (e.g. 500 for the BHK 500-

0.4MG),

• EomaxB is the rated maximum output voltage for unit B.

c. Program overcurrent value of unit A (IocsetA) to 1.1 x current limit for power assembly

(step 3a).

d. Program overvoltage value of unit A (VovsetA) to 1.1 x VsetA (step 3b).

4. Program unit B as follows:.

a. Program IsetB to approximately 1.01 to 1.02 x IsetA (step 3a). This maximum current

limit is never used except in the unlikely event that the current limit of Unit A is not work-
ing.

b. Program VsetB to (Eo – VsetA) (VsetA is set in step 3b).

c. Program overcurrent value of unit B (IocsetB) to 1.1 x IsetB (step 4a).

d. Program overvoltage value of unit B (VovsetB) to 1.1 x VsetB (step 4b).

5. To apply power to the load:

a. If load switch used, close the switch.

b. If load switch not used, press POWER ON/OFF key (once) on unit B, then unit A.

6. To disable power to the load:

a. If load switch used, open the switch.

b. If load switch not used, press POWER ON/OFF key once: first on unit A, then on unit B.

c. Alternative: Turn both units off by setting POWER switch to off (down) position, first on

unit A, then on unit B.
