54 Process interlock1
Case 1: When t1>t2, motor can run normally.
Case 2: When t1<t2, a trip or stop will be
performed according to the predefined
operation.
Process interlock works on level
check mode which means once the in-
terlock is activated, motor is locked
down until the interlock changes to
deactivated.
Process interlock may cause motor to
trip when activated. Once it is deacti-
vated, the trip is reset automatically.
• Process interlock2
Similar as process interlock 1, process interlock 2
provides a time dependent trip/alarm/stop fea-
tures based on a switch input. Different from
process interlock 1, process interlock works on
the complete motor operation process which in-
clude starting period, running period and stop.
The related parameters to process interlock 2 are
the same as process interlock 1.
