4.2 Gear Train
A precision cut bronze or ductile iron worm gear set delivers maxi-
mum strength and durability. For optimum performance the gear set
is permanently lubricated and submerged in oil in a sealed compart-
ment.
High performance Petro Canada Syndro SHB-68 oil is used for stan-
dard temperature requirements. The compartment volume is 12oz. Oil
replacement is not required under normal operating conditions.
Options and Adjustments (Factory Installed)
Magnetic Rotary Positioner Sensor
Shaft position feedback is accomplished using a 12-bit magnetic
rotary position sensor directly coupled to the output drive. Specifically
designed for brushless DC (BLDC) motor control, this technology
provides the highest accuracy and reliability.
Position and Alarm Outputs
4 outputs are provided as standard and pre-wired to the terminal
block. Standard outputs are non-latching, dry contact,15A rated.
Optional latching contacts are available; consult Flowserve.
Outputs may be configured for remote position indication and/or
alarm feedback.
When alarms are activated, additional “action” may be programed:
> DO NOTHING (factory default)
> GO to OPEN
> GO to CLOSED
> MANUAL MODE
Also note that the relay stays energized during an alarm condition. It
deenergizes when the value is outside of the MIN/MAX range entered.
Factory default settings:
Output 1: position CW
Output 2: position CCW
Output 3: Alarm High Torque
Output 4: Alarm Compartment Temperature

*Factory Default
Rotation speed is factory set to the fastest 90 degree rotation per the
actuator model code specification (Example: M60 = 5 seconds). Both
the CCW and CW rotation speed is independently adjustable with 10
pre-set selections that increase rotation speeds up to 180 seconds.

*Factory Default
Example Model 60: 600 in-lbs set at 100% = 600 in-lbs;
set at 75% = 450 in-lbs.
Torque output is factory set to the maximum value per the actua-
tor model code specification (example: M60 = 600 in.lbs.). Output
torque is adjustable from 100% to 40% of rated value with 10 pre-set
selections.

15 360/hr 1800 Starts/hr
60 360/hr 1800 Starts/hr
150 180/hr 1800 Starts/hr
The CEA actuator is rated for 1800 starts per hour, under full load
conditions, within the normal operating temperature limits per
specification listing.
4.6 Heater and Thermostat
Heaters are not required for operation to -40C and/or to control
condensation. Condensation does not occur due to non-breathing
enclosure and internal compartment temperature stabilization. The
customer may order a factory-installed heater and thermostat if
desired.
