Safety requirements
Safety Notice
The SLATE Actuator has been independently
evaluated by Underwriters Laboratories to
provide position feedback to the SLATE Fuel Air
Ratio Module. The safety of the overall system
is ultimately the responsibility of: 1) The
upstream safety control that commands and
monitors the SLATE Actuator, and 2) the
trained commissioning engineer that
configures the unit for system operation.
Safety Hazard
Before operating this product, check all
specifications and safety requirements to
ensure the product is suitable and safe for the
intended application. In addition, read all
installation, commissioning, and operating
instructions. The SLATE Actuator must be set
up and maintained in the field by qualified
personnel. If the equipment is used in a
manner not specified, the protection provided
by the equipment may be impaired.

Mounting
The actuator assembly may be installed in any
orientation.
Keep Free of Dust and Water
• Maintain the integrity of the enclosure by
using NEMA 4X rated dust- and water-tight
electrical connectors.
• Use cable-sealing grips and strain-relief
loops for any cord or cable.
• Plug unused conduit holes. Use internal
sealing materials on all conduit connections.
Moisture can have a harmful effect on device
internals if permitted to enter through wiring
connectors.
• Ensure that the device connection is not at a
low point of the conduit to avoid
condensation run-off into the housing;
install a drip loop if necessary.
• All cover screws should be tightened to the
specified torque. See Fig. 4.
• Cover screws should be checked periodically
to ensure adequate sealing protection.
If you are mounting the SLATE™ Low Torque Actuator
using third party valves, it is important to follow the
following assembly instructions:
1. Ensure that the SLATE™ Low Torque actuator
has sufficient torque for the valve's required
break-away torque. Also consider the line
pressure when making this calculation.
2. Turn off the fuel supply upstream from the
applicable valve.
3. Remove all external hardware from the third
party valve.
4. The SLATE actuator's shaft is ½-in. diameter
with a 1/8-in. square key. For a smaller 3/8-in.
valve shaft you must insert an adapter so that
the two shafts are concentrically aligned, ensure
that the set screws solidly contact both shafts.
5. If the bracket assembly permits, attach the
coupling to the valve and the actuator first,
ensuring exact alignment. After the coupling is
tightened, assemble and tighten the mounting
brackets. Do not tighten the mounting brackets
first.
6. Observe the actuator while it travels over its
entire range and ensure smooth operation. If
sticking/binding is observed, or if Slate reports
actuator error codes, the actuator shaft is not
properly aligned and must be re-adjusted.
Ensure the media temperature cannot exceed the
valve or actuator ratings. Use a coupling with thermal
breaks if required. If the possibility exists for radiant
heating (such as a furnace application), install a
thermal barrier.
Ensure that pipe and ductwork are free of debris that
could impair valve function.
See Fig. 2 for the locations of the mounting holes. The
mounting holes are threaded for M6 x 1 x 1/2-in
(12mm) fasteners.
Fig. 2. Mounting holes.
Note the quadrant of the keyway and rotation
direction. See Fig. 3.
Fig. 3. Actuator rotation direction.
NOTE: The SLATE Actuator ships CCW as default.
Electrical installation
Electrical Shock Hazard.
Can cause severe injury, death or equipment
damage.
Disconnect the power supply before beginning
installation to prevent electrical shock and
equipment damage. More than one power
supply disconnect can be involved.

To access the field wiring compartment for power and
signal connections:
1. Remove the 2 screws and cover from the top of
the actuator housing.
2. Pass all customer-supplied wires into the enclo-
sure through the 2 conduit hubs.
SLATE™ LOW TORQUE ACTUATOR SERIES
4. In addition to a grounded conduit, the use of
shielded, twisted-pair cable is strongly recommended for DC power and signal wires. The
shield drain wires should be landed to chassis/earth on both ends of the cable, but ONLY if
a conduit is also grounded on both ends. In other
cases, earth the shields at actuator end only.
Input power
IMPORTANT
Use DC power only.
Use cable rated for the temperatures and voltages
required by the application. Use a gauge of wire to
minimize voltage loss (droop) over long cable runs,
especially at full current load. Ensure that voltage
specifications are met under all conditions.
See Table 2.
A fuse or breaker should be installed at the power
source. If the power supply is not factory-supplied, a
SELV (Safety Extra Low Voltage) rated supply with
regulated output must be provided.
Communication (Modbus over RS-485)
Use appropriate communication cable. A network will
consist of a customer’s Modbus master (with
termination) and one or more actuator slaves. See
SLATE documentation for wiring specifics.
Equipment Damage
To ensure physical protection as well as
electromagnetic immunity, the use of flexible,
sunlight-resistant, jacketed, metallic, watertight conduit is required. The conduit should be
connected to earth ground on both ends.
3. One or both conduit holes may be used when
wiring an actuator.
NOTE: On commercial models only:
Do not wire the non-isolated common
terminal to the Slate system; leave it
unconnected. Instead, wire the 24V- of the
actuator supply to Pin 2 of the Slate
Sub-Base. If all actuators share the same
supply, only one connection is needed.
Network layouts should be arranged so that
branch/homerun length does not exceed 300 feet for
commercial actuators, or 2000 feet for industrial
actuators.

CAUTION
OPERATING INSTRUCTIONS
The SLATE Actuator is designed specifically for the
SLATE Fuel Air Ratio Module. For actuator operation
and programming information, see the SLATE Fuel Air
Ratio Module document 32-00006 and other SLATE
system documentation (Base Module document 3200005, and System Checkout guide 32-00016).
Read instructions carefully.
Read the instruction manual carefully before
initiating the start-up and adjustment
procedure. Verify that all of the equipment
associated with and necessary to the safe
operation of the system has been installed
correctly, that all pre-commissioning checks
have been carried out successfully and that all
safety-related aspects of the installation are
properly addressed.
Overview
SLATE Actuator provides multiple methods for
actuator commissioning, precise closed-loop valve or
damper position control, and health monitoring.
• Position can be commanded via Modbus using the
SLATE Fuel Air Ratio Module.
• Commissioning is accomplished through the
SLATE Fuel Air Ratio Module.
TROUBLESHOOTING
If the two shafts are not perfectly and concentrically
aligned, additional binding and torque will be
introduced into the assembly causing error codes to
be sent from the SLATE actuator to the SLATE Fuel Air
Ratio Module resulting in an inability to properly
commission the system. If you are receiving actuator
error codes either on the SLATE main module or in the
error code register, check the mounting brackets and
coupling's alignment and make necessary
adjustments.
Alarm and lockout event reporting
SLATE alarm and lockout codes are accessed through
the SLATE Fuel Air Ratio Module or using the SLATE
touchscreen display. See documents 32-00013 and
32-00006 for more information.
The Low-Torque Actuators also display status
messages through LED blinks. The LED is on the PCB
inside the unit. These can be used for troubleshooting
purposes.
The cover of the Low-Torque Actuators must be
removed to see the two LEDs:
• Green LED: displays status, including alarm codes
• Yellow LED: displays communication activity
(on RS-485, bus is working and actuator is
communicating with SLATE system)
The normal and error codes are shown in Table 3.
