Technical data, comments
If the firing pulse transformer module is divided up (please refer to the
section titled "Removal/Installation and division of modules"), the
controls for the firing pulse transformers must be routed via these
terminal connections.
This involves making the following connections:
XIMP_1 - IMP11 → XIMP11 - IMP11 (for thyristor V11)
XIMP_1 - P24 → XIMP11 - P24 (for thyristor V11)
XIMP_1 - IMP12 → XIMP12 - IMP12 (for thyristor V12)
XIMP_1 - P24 → XIMP12 - P24 (for thyristor V12)
etc.
If the firing pulse transformer module is divided up (please refer to the
section titled "Removal/Installation and division of modules"), the
controls for the firing pulse transformers must be routed via these
terminal connections.
This involves making the following connections:
XIMP_4 - IMP21 → XIMP21 - IMP21 (for thyristor V21)
XIMP_4 - P24 → XIMP21 - P24 (for thyristor V11)
XIMP_4 - IMP22 → XIMP22 - IMP22 (for thyristor V22)
XIMP_4 - P24 → XIMP22 - P24 (for thyristor V12)
etc.
Only to be connected if the firing pulse transformer module is divided
up (see terminal strip XIMP_1)
