Warning Description

Warning status does not affect the ICON3000 operation, it only indicates that some
variable is near to critical value and could in future generate an alarm. It is better to fix the
warning as soon as possible.
2.3.1 Warning on Local Display: High Torque in Closing

2.3.3 Warning on Local Display: Internal Temperature
(Near to Maximum)
The temperature inside the actuator enclosure is higher than 80 °C or lower than -35 °C.
Any electrical command is cleared. The warning disappears when temperature is within
the range +80 °C, -35 °C.
Check ambient temperature.
Troubleshooting
Check the valve and the torque needed to move the valve.
Check the torque limits in Actuator Setup, Stroke limits and torque setup.
Increase the torque limit only if valve stem can accept more torque/thrust/
without any damage.
Repeat "stroke limit" setup procedure in case of change of torque limit and valve
closes or open by torque.
