The actuator can be mounted in any position. The actuator is suitable for short-
time duty.
The Maximum rated torque and thrust should not be applied over full range of
travel, except for valve with short stroke. The maximum rated torque(Nm) can be
applied to 10% of travel and remaining 90% of travel can be applied with 30% of
rated torque(Nm).
Bore in coupling flange must have sliding fit on the input shaft. Excessive seating
may damage the actuator during fitting.
Positioning of actuator on the valve is made easy by spigot on mounting flange.
The corresponding seating should be made to grade H8. Check the proper
seating.
• Do not operate the actuator with improper wiring.
• Do not interchange the cards without checking the e-pac code.
• Do not interchange the e-pac without checking the rating.TOLR
• Improper sealing of cable glands resulting in water entry at site will inadvertently
damage all the electronic cards.
• Do not operate the actuator in manual mode while electrically operating.
• Please check the input voltage rating of the motor before giving supply.
• Do not run the NORM actuator without panel.
• Do not bypass the thermoswitch connection in the loop.
