BOP 1000W MODELS (2) IN PARALLEL

I.

DESCRIPTION.

This kit contains the three cables, Power Output, Bitbus and Master/Slave Control, required to operate
two 1000 Watt BOP High Power models in parallel, effectively doubling the output current capacity.
Only two identical models may be configured to operate in parallel. Table 1 lists the equipment supplies
in this Kit.

NOTE: The following procedure assumes that both individual units are properly calibrated. If not, refer

to the associated technical manuals to calibrate the individual units prior to connecting them
as a parallel pair. Perform all calibration steps for both master and slave unit.

1. Before powering up the parallel combination, connect the Power Output, Bitbus, and Master/
Slave Control cables (supplied) to the master and slave units in parallel star type configuration
(load connected to the master output) as shown in Figure 1 for local sensing or Figure 2 for
remote sensing. Always remove link between COM and COM S terminals for the slave. For a
master configured for remote sensing, remove both links between OUT and OUT S and between
COM and COM S terminals.

CAUTION:The connectors of the Master/slave Control cable are marked Master and Slave.

Make sure these are installed properly. Installing the cable backwards (cable con­nector marked MASTER installed in a slave, cable connector marked SLAVE
installed in a master) can cause irreparable damage.

NOTE: To power down the combination, first press the STANDBY key on the master to disable the

output, then turn off the slave followed by the master.

2. To configure the unit to be designated as a slave proceed as follows:

a. Turn on power only to the unit to be designated as a slave.

b. From the main screen (power on default), press

to enter the Settings Menu.

NOTE: Pressing

f. The power-up master module screen (Figure 3) changes to show the status of Slave 1 (see

Table 2).

If the slave is recognized as ready, after about 10 seconds the master LCD reverts to the

Power On Default screen (see Figure 4). The slave also displays the Power On Default
screen (see Figure 5), except the unit will be in Current Mode, no function keys are active
and the Status message at the bottom is

KPAD Locked

, indicating the keypad is disabled.

The fault indicators on both units are off.

If the master power-up screen is still displayed after 10 seconds, the slave was not properly

recognized. Pressing

or turning power off, then on again, reconfigures the unit as a stan-

%

dalone unit. Verify that the BITBUS cable is installed correctly. Verify that the slave has
been properly configured as a slave per step 2 above. Repeat step 3. If the power up
screen still does not revert to the power on default screen, refer to troubleshooting.
