RECOMMENDED ACTION
Check PST travel and
parameter OV-TR.
Check if condition to abort
has happened.
Check section of wires
and values of voltage and
frequency.
Recalibrate both stroke limits.
Check the torque necessary to
move the valve.
Change contactor and reset
operation log.
Find the heat source and
insulate the actuator.
Check electrical motor.
Perform maintenance and set
next maintenance date.
Operator is changing the
actuator position
by handwheel.
Check and remove the ESD
condition (C4 pin of terminal
board or FF ESD command).
Check the Interlock condition
(B4 and B5 pin of terminal
board or FF Interlock
command).
Release the Local Stop button.
