Manual 37278B GCP-30 Series - Genset Control

GCB Pulse/Continuous Pulse

Closing and opening of the GCB and the MCB are described in the following figures (Figure 3-6 and

Figure 3-7). Changing of the breaker control logic is configured using Parameter 129 and has the described effect

on t

he signal sequence (the operation of the MCB cannot be carried out by means of the continuous pulse). If the

"Automatic breaker deblocking" (Parameter 137) is configured to "ON", an open pulse is issued prior to each

ose pulse. The discrete input "Enable MCB" (terminal 54) enables/disables closing the MCB. A closed MCB is

not opened.
