4.2.2.
Allarme di Power Faut
The SSR_SHORT alarm cannot be diagnosed in
GRP-H-x-x-x-0-x-x-x-x-x-x models.
The POWER_FAULT diagnostics can be configured
via the hd.2 parameter, with which it is also possible
to enable only a part of it.
• SSR_SHORT SSR module shorted
• NO_VOLTAGE lack of line voltage
• NO_CURRENT for SSR module open or load
interrupted
The NO_CURRENT alarm is triggered with load
current threshold < 4% product current size, e.g. for
GRP-H-25-x-x-0-x-x-x-x-x-x the alarm is triggered with
load current lower than 1A.
For HB alarm (partially interrupted load) refer to the
relevant section of this manual.
