Notes on use with inductive loads and transformers
•
When the GPC controller is in operation, it is NOT
permissible to disconnect the connection between the
GPC and the transformer or between the transformer
and the load.
•
The maximum current that can be controlled by the
GPC is reduced compared to the nominal value of the
device (see technical specifications).
•
In ZC and BF trigger modes use the delay-triggering
function to limit the peak magnetising current.
•
In PA trigger mode use softstart function
•
DO NOT use the HSC trigger mode.
•
Do not connect RC snubbers in parallel to the trans-
former primary.
•
Always set DIP switch No. 5 to ON (and carry out the
initial configuration procedure described in paragraph
"1.6.2. Initialisation procedure and loading of default
values").
