Eclipse Rotary Actuator Instruction Manual 904-7/24/06
7
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 regu-
late 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 auxil-
iary contacts; and direction of rotation.
The display keypad can be ordered in four posi-
tions: 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 connec-
tions 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.
