ECP SERIES OPERATIONAL CONCEPTS

ECP Series multivoltage electric actuators are motor powered, gear driven actuators for valves, dampers, and
other applications. They can be used with any power supply 24VAC/VDC - 240VAC and feature manual override
handwheels, easily visible position indicators, and a status LED.
All ECP Series actuators rotate CW to CLOSE the OUTPUT shaft out the bottom of the actuator when viewed
from ABOVE. This includes the direction of rotation of the internal cam shaft when viewing with the cover and
indicator removed.
All ECP Series actuators are designed to rotate between 0° and 90° (standard) or between 0° and 180° (option). When
using the manual override system, be sure the yellow position indicator is situated in the correct quadrant before
returning to automatic operation to prevent erratic operation of the actuator under power (see page 6).
Available options for the ECP Series include: Proportional Control with digital feedback, Battery Backup, or Rotation
Options (0°-45°, 0°-90°, 0°-180°). Not all options are available in all combinations for all products in the series.
This IOM is supplied with ECP Series actuators that may have been shipped separately or as an assembly of the
actuator and a Hayward ball or butterfly valve. If this actuator was provided as part of the Hayward assembly, a
separate IOM for the valve should be included in your shipment.
Notice: ECP Series actuators are fully assembled, calibrated and tested prior to leaving our factory. In most cases, after
you have mounted the actuator to your device, you should be able to operate the actuator from fully CLOSED (CW) to fully
OPEN (CCW) and back again, and find that no adjustments are needed. The assembly can be put into service immediately
and should afford the end user years of service without incident. However, should it be necessary to make adjustments to
the end-of-travel positions to overcome any device related issues (i.e. valve shaft incorrectly timed to the drive stem), the
procedures outlined on the page numbers referenced below should be followed to put the assembly into service.
