Actuator User Manual
Description
The Series 19 Model C20HM2W (on/off) & C20HM2FSW (Failsafe) electric actuators
features a reversing motor with multi-voltage capabilities; 95vac-265vac (50/60Hz) or 24
Vac/Vdc. An internal heater, and auxiliary switches are standard equipment. Additional
features include a NEMA Type 4X enclosure, manual override, visual mechanical
position indication, LED Indication (Open/Closed) ISO bolt circle, and flying leads. The
auxiliary switches are SPDT and rated for 0.1A @250 Vac, and are factory calibrated.
Failsafe units are capacitor discharge design, and may require up to 15 minutes to
charge when initially provided power.
Additional options are NOT available for these Series 19 Models

Manual Override Operation
This procedure is for both, on/off & Failsafe Units
Remove manual override Hex Key from storage position located on the bottom of
actuator, which is secured by SS clips. To operate the manual override, insert hex key
into hex socket located on top of actuator and rotate to manually cycle valve (CCW to
open, CW to close). When finished using the manual override it is imperative to remove
the hex key and place it back into storage on actuator base, making sure that it “clicks”
into the locking position.
CAUTION: The manual override should only be used when there is no power applied to
actuator. When power is restored the actuator will automatically resume normal
operation.
Switch Calibration
This procedure is for both, on/off & Failsafe units
Open Travel Limit Switch (Bottom Switch Cam 2):
Using manual override, move the valve into a full open position. Then loosen L2 set
screw on bottom cam (Cam 2) and rotate cam CCW into limit switch until two clicks are
heard, this designates the switch circuit has opened and defines a full open position.
Tighten L2 set screw on Cam 2.
Close Travel Limit Switch (Top Switch Cam 1):
Using manual override, move the valve into a full closed position. Then loosen L1 set
screw on top cam (Cam 1) and rotate cam CW into limit switch until two clicks are
heard, this designates the switch circuit has opened and defines a full closed position.
Tighten L1 set screw on Cam 1.
