After the controller operates the bank for the first time, the sequence of events
will be stored in memory. View the SER records as shown in the previous
section, then use the following guidelines to ensure that the controller
operated the capacitor bank properly.
Full-Size Enclosure
The Full-Size Enclosure contains three pairs of output contacts (three open
contacts and three close contacts) to control three single-phase capacitor bank
switches. Auxiliary 52a and 52b contacts can be connected to the SEL-734B
enclosure, but these are optional.
Use the following guidelines to ensure the controller operates the switches
properly.
➤ For a three-phase operation, ensure that all three output
contacts operate simultaneously.
➤ For single-phase operations, ensure that only one output
contact operates.
➤ Ensure each output contact remains asserted for a short
duration, as configured.
➤ If the 52b contacts are connected to the enclosure, ensure the
signal asserts when the switch is open. Ensure the signal
deasserts when the switch is closed.
