The Eclipse Programmable Rotary Actuator is a
keypad-programmable, direct-coupled modulating
motor for use in burner and valve control systems.
It is typically used with an electronic control to regulate a process temperature. The drive shaft of the
actuator connects to a buttery valve stem, which
rotates 90 degrees from minimum to maximum
position.
Actuator features include: solid state electronics;
LED display with membrane keys; 4-20mA, 0-10Vdc
and switch inputs for positioning; and two auxiliary
contacts for position feedback.
The display keypad provides indication of position
and direction of travel, and allows local manual
positioning control. It also provides access to set
the following parameters: minimum and maximum
travel positions; actuation position for the auxiliary contacts; and direction of rotation.
The display keypad can be ordered in four positions: upright (standard) for vertical mounting
with the wiring connections at the bottom; 90
degrees (RH) for horizontal mounting with the
wiring connections to the right; 270 degrees (LH)
for horizontal mounting with the wiring connections to the left; or inverted for mounting with
the wiring connections at the top. (See page 32
for additional keypad orientation illustrations.)
The keypad orientation cannot be changed in the
eld.
Note:
These instructions apply to heating applications
where a maximum output from the tempera-
ture controler drives a buttery valve up to its
maximum ow position.
instructions that you need to install the actuator.
Caution:
Installation and maintenance must conform
with the National Electrical Code and all other
national and local codes and authorities having
jurisdiction. The actuator must be installed by a
qualied, licensed technician.
Handling
1. Make sure that the area is clean.
2. Protect the actuator from the weather, dam-
age, dirt and moisture.
3. Protect the actuator from excessive temperatures and humidity.
4. Take care not to hit or drop the actuator.
Storage
1. Make sure that the actuator is clean and in
good condition.
2. After you have made sure that everything is
present and in good condition, keep the actuator in the original package as long as possible.

A Note on Safety
The Eclipse Programmable Rotary Actuator must
be used with an approved listed combustion con-
trol system consisting of a ame safeguard and
safety shut-off valves. The diagrams below illustrate the general arrangement of the typical control schemes. These diagrams do not show all of
the devices that may be required for a complete

Caution:
Use of this product in the European community
shall only be deployed in a manner that meets
the applicable EC directives and laws.
Depending on your application, please keep the
following in mind when mounting the actuator:
• The actuator housing has three mounting holes,
as shown in Figure 1. The holes are threaded and
use M6 metric screws.
• Mounting this actuator depends on the application; See Data 904 and contact Eclipse, Inc. for
available mounting kits.
• When mounting the actuator, be certain that the
actuator’s drive shaft is properly aligned with the
other shaft to which it will be coupled to avoid
undue lateral stress.
• The actuator’s drive shaft has a 3mm through
hole for a coupler, as shown in Figure 1.
• Provide support for the weight of conduit or
cables into the actuator.
