Initial Inspection
Ensure product specification on nameplate and wiring
diagram matches the application and order.
Check actuator for any physical damage that may have
occurred during shipment.
If there are any discrepancies, contact your Triac
distributor to solve the problem immediately.

Installation & Maintenance Manual
4. Information and Features
The WE, SE, XE and XC series electric actuators are for
use on quarter-turn valves and dampers requiring
between 690 to 25900 in-lbs of torque to operate.
Actuator positioning is achieved by travel limit switches
that disconnect power to the motor when engaged by
cams attached to actuator output shaft. A thermal
protector switch is built into the motor windings to
automatically disconnect the motor power if the motor
temperature exceeds the motor rating. Torque switches
are included on all actuators, except -690 size, as a
safeguard to prevent stalling and overheating the motor.
The ratio of the motor and gear train determines the
actuator speed and utilizes two worm gear sets to
transfer the motor torque to the output shaft. The double
worm gear configuration prevents the load from back
driving the output shaft. Accurate positioning is achieved
by the indicator cam shaft connecting directly to the
output drive.
