Introduction
This document provides necessary information for set-up, calibration, testing and use of the P Series quarter-turn
electric actuators stated on the cover page. Each unit is shipped from the factory with initial calibration of mechanical
stops, cams and switches completed for 0-90 degree operation. However, these are general settings and serve as
a starting point for proper calibration of the actuator in its real-world application.
Safety
Safety is a basic factor any time you maintain and operate mechanical equipment. Appropriate handling
methods and proper use of tools and personal protective equiptment (PPE) can help prevent serious accidents
which can cause injuries to you or a fellow worker. This manual was created to enable a trained user to install,
adjust and troubleshoot your ProMation actuator.
Only competent and trained personnel should install, maintain and operate ProMation actuators. Any work
related to this actuator must be carried out in accordance with this manual and related codes and regulations.
Local workplace health and safety rules must always be followed.
Duty cycle
Duty cycle is the percent of time that an actuator spends running as a fraction of the total time. Duty Cycle is
directly related to heat; excessively repositioning an actuator typically results in motor overheating which can
cause permanent damage and/or reduced service life.
Duty cycle can be calculated as follows:
(example P2 series actuator running 3 seconds ON and 30 seconds OFF)
Runtime = 3s, Total time = 3s + 30s = 33s, therefore this duty cycle would be 9% (3/33)
Additionally, ProMation P series actuators are designed for a maximum of 1200 starts per hour (one start every
3 seconds maximum).
These may be equipped with internal
torque switches (-TS) which protect
the gear train, motor and controlled
equipment from damage when high
torque conditions exist.
These protective devices are NOT
adjustable. More information on this
techology is found throughout this
manual.
