Safety Ratings
Mechanical
Cover Bolts: ¼-20 18-8 Stainless Screw (installed at factory). Should not be tightened with anything greater than 75
in-lbs of torque
Module Screws: 6-32 18-8 Stainless Screws (installed at factory). Should not be tightened with anything greater than
9.6 in-lbs of torque. Screws have threadlock applied to them before being tightened down; when removing start slow
to lessen risk of breaking screw.
F07 Valve Mounting: Holes are threaded for M8 x 1.25 screws. The bolts will be provided by distributor or end user.
Follow guidelines based on material of screw. Typical tightening torque is 48.8 newton-meters. All four bolts with lock
washers should be used to secure valve.
F10 Valve Mounting: Holes are threaded for M10 x 1.5 screws. The bolts will be provided by distributor or end user.
Follow guidelines based on material of screw. Typical tightening torque is 97.5 newton-meters. All four bolts with lock
washers should be used to secure valve.
Conduit Input: Holes are threaded for ½ - 14 conduit. Conduit should be tightened using 15 in-lbs of torque. If using
pipe thread sealant or teon tape, conduit should be tightened 2-3 turns with a wrench past nger tight for best seal.
Coupling: Coupling is designed for 27mm diameter valve stem or adapter. If adapter or valve stem do not easily slide
into coupling, do not attempt to hammer in to place as it will damage the gearbox. Either attempt a new adapter or
reach out to local distributor for assistance.
Electric/Wiring
Panel Fuse: Size fuse to respective power input. Max 4A fuse
PS048/XCTRL Power Input: 48VDC | ~1.67A max current draw (connector supplied)
PS024 (or PSUNI 24VDC Input) Module Power Input: 24VDC | ~3.3A max current draw. 12-24 AWG Input. Size wire
appropriately for length of run.
PS120 (or PSUNI 120VAC Input) Module Power Input: 100-240VAC | ~0.47A | 50/60Hz. 12-24 AWG Input. Size wire
appropriately for length of run.
XCTRL Terminal Block Inputs: Voltages vary per terminal. Refer to Section 3.2 for terminal ratings. 14-28 AWG
Input. Size wire appropriately for length of run.
Note: Full actuator has ability to draw less when not moving the valve if power is an issue. Actuator may be put into low power mode which will
turn off the holding torque of the motor after movement completes. Should only be used in low-pressure situations.

Operating Temperature: -40°C to 60°C (-40°F to 140°F)

Failure to comply with the following limits may result in physical damage to actuator or possible harm to installation
technician. It may also result in voided warranty and incur additional repair/shipment costs.
Section 1: SmartStep Introduction
1.1 The Actuators & Module Options
The SmartStep actuator is available in two different
sized housings and ve different torque options.
The X-Series is in a larger casting that is suited for
F07 and F10 ISO mounted valves that are rated
between 500-5000 in-lbs. The S-Series is roughly
20% smaller than the X-Series and is suited for
F05 and F07 ISO mounted valves that are rated
between 400-1200 in-lbs. Note: As of the creation
of this document revision, the S-Series is in the
prototype stages and should be released by Q1 of
2024.
Both actuators use the same power input modules.
The modules may be congured for 24VAC,
24VDC, or a 24VDC & 100-240VAC universal input
module to allow stocking of a single supply.
Both power modules, if ordered with the -EPB
option may be congured with a SuperCap backup.
The capacity of the EPB currently allows any of our
modules to move 90° to their Failsafe position
during an power loss or control signal loss. The
smaller models will be capable of moving more
than that as the lower torque requires less power
draw.
The SmartStep control module (XCTRL) and the
power supply modules (PS024, PS024-VAC, and
PSUNI) are all designed to be eld replaceable. If
there is a failure on one of those modules, or if a
24VDC power input module needs to be swapped
to a 120VAC power input module, it’s as simple as
removing a few cable connections and three
screws. So if there is an issue, reach out to nd out
if a module can be replaced so that the entire
actuator doesn’t have to be sent back.

Warranty
All SmartStepTM actuators and modules are covered by a 2-year warranty that covers standard actuator operation and
workmanship. The warranty expires 24 months from delivery date.
If an actuator is not operating in the expected manner, please reference the trouble-shooting section of this document.
If further assistance is needed contact your local distributor or [email protected]
If an actuator has failed under normal operation you may request a return material authorization through the distributor
through which the actuator was purchased.

3.3 Basic User Menu Map
Starting from the MAIN screen, basic status and
diagnostic information about the module may be
obtained by using the Up/Down or Right/Left Arrow
buttons as shown to the right.
The ESC button will return the unit to the home
screen any time that a parameter is not being
edited.
If a parameter is being edited, ENT will store the
new setting; ESC will cancel the input.
3.4 MAIN Screen Elements
1) Percentage that valve has opened from closed position
2) Current RUN mode selected
3) Varies on actuator status/options selected:
a) EPB Model and shaft not moving: Displays
current cycle count of actuator
b) EPB Model and shaft moving: Displays current
desired shaft position
c) Non-EPB Models: Displays current desired shaft
position
d) The entire line (elements 3 & 7) may also be
used to display faults. For a list of faults and
their explanation go to the Troubleshooting
section.
4) Varies on actuator options selected:
a) EPB Model: Displays Voltage Input detected on
PSXXX-EPB module if the SuperCap rmware is
version 3.0 or above.
b) Non-EPB models: Displays currents cycle count

5) Super Cap communication/charge status
6) Different RUN Mode status information is displayed here:
a) If RUN mode is set to 4-20mA, the current mA
signal value is displayed
b) If RUN mode is set to One-Wire or On-Off, then
the current J1 setting will be shown. If J1 is set
up to have CLOSE as the command signal,
J1:CLS will be displayed if not actively receiving
a command signal. Once the command signal is
detected status will be J1:+CLS+
7) Actual position of the valve
8) Displays current internal temperature of the actuator as
well as the direction the valve will always turn to go to
the OPEN position
