Lock-out
TRPPTRC is provided with possibilities to activate a lockout. When activated, the
lockout can be manually reset after checking the primary fault by activating the
RST_LKOUT input or from the LHMI clear menu parameter. When using the
"Latched" mode, the resetting of the TRIP output can done similarly as when using
the "Lockout" mode. It is also possible to reset the "Latched" mode remotely through
a separate communication parameter.
The minimum pulse trip pulse function is not active when using the
"Lockout" or "Latched" modes but only when the "Non-latched"
mode is selected.
