FIGURE 3-23. LOCAL (FRONT PANEL) CONTROL OF THE BOP CURRENT LIMIT CIRCUITS
The BOP current limits can be remotely controlled by disconnecting the fixed reference poten-
tial, setting the front panel controls to their maximum clockwise position, and substituting a vari-
able (0 to 10 volt) reference potential. The two limits may be controlled simultaneously and
symmetrically, or separately. The necessary connections are shown in FIG.'s 3-24 and 3-25
respectively.
