Toyodenki Contactors

(OP)
Hi All

We are having a problem with old Toyodenki contactors (Obsolete with no spares in RSA). They keep on tripping on anti-pump.
We are switching capacitor banks, thus the anti-pump circuit.

Does anyone know where I can get some info and manuals on these contactors. I need to know how to test the economy resistor, holding coil and vacuum pressure?

Thanks in advance.
