Series 19 SMART Modulating Failsafe Electric Actuator User
Manual
Description
The Series 19 smart modulating electric actuator features a reversing motor with multi-
voltage capabilities, 95 VAC to 265 VAC (50/60 Hz) or 24 VAC/VDC, an OLED screen,
an internal heater, positioner, transmitter, alarm/fault contacts, a NEMA Type 4X
enclosure, manual override, visual beacon position indication, LED fault indicator (blue),
ISO mounting, and flying leads. The alarm/fault contacts are SPST and rated for 0.1
Amp @ 250 VAC/0.5 Amp @ 30 VDC, and are factory calibrated.
Cover removal is NOT required for installation and will void warranty!!
Additional options are NOT available for this model.

The Series 19 electric actuator has a sealed cable gland with 2 meter flying leads. The
electrician is required to make field connections as per the wiring schematic shown in
this manual for model numbers and voltages listed above. The electrician is responsible
for following all and any, local and/or agency wiring practices.
Note: Not all wires provided will be used.

Failsafe ability is disabled for ALL units until capacitor charge reaches 100%. Unit will
function as on/off until capacitor is fully charged. Heater is internally wired and
operational as long as actuator is powered.
Size 20 ONLY
Size 20 is specific to accept only voltage or current as a control signal/loop
Size 20 will be labelled specifically as a voltage or current control signal/loop, and
cannot be changed via onboard firmware. If a different control signal/loop is required,
then another unit with the specific control signal/loop must be used.

Size 50 – 110
Size 50 – 110 can be calibrated for EITHER a voltage or a current control
signal/loop via onboard firmware. Please contact the factory for instructions.

Manual Override Operation
Remove manual override hex key from storage position located on the bottom of
actuator, which is secured by stainless steel 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.
Local Controls Operation
The actuator can be locally controlled and driven to the open or closed position via
OLED screen and push buttons. This simple procedure is detailed below.
Press and hold the “↕” button for 3 seconds. “K3” will flash in the top right hand corner
and the unit will ask for a password. At this time, the password of “111” can be entered
with “↕” selecting numbers and “↔” selecting the field. Once password is entered, press
the “M” button to enter manual mode. The actuator can now be opened and closed via
the push buttons. Press the “↨” button to OPEN the actuator. Press the “↔” button to
CLOSE the actuator. To exit manual mode, press the M button or wait approximately
120 seconds and the manual mode will time out and exit. The actuator will not respond
to control signals from the PLC until taken out of manual mode.
Troubleshooting
Actuator does not respond
Power not connected Connect power
Voltage below level or incorrect Confirm correct voltage
Torque limiter tripped
Power unit in opposite direction, then
power to original position to confirm a
tripped torque limiter
Loose/poor termination Confirm proper termination

Troubleshooting Continued
Actuator does not respond
Incorrect signal provided to actuator
Verify that control signal from PLC
matches control signal of actuator. *Size
20 is provided as ONLY accepting a mA
signal or ONLY accepting a current control
signal
Crossed signal wiring
Confirm that control signal wiring is
terminated at the appropriate wiring
location of actuator (0-10 VDC signal
connected to 4-20 mA actuator wiring, as
an example)
