I just inherited six MCLVV2 Maida elevator controllers with IPC Automation BI-Directional Field Regulator.One of the cars keeps getting people stuck not locks or gate.Had 500K on gen blew out now have 2meg.Building does a one arm bandit before I can get there so everything fine when on site. So I sat on it an seen regulator say OUT OF REG an car stop high at floor an not open doors. Checked tach coupling all control wire sockets terminals an relay connections. Does anyone have any knowledge of this type equipment would be of great help. I think this is a Virgina control early solid state with gen.
