3.1 General Product Description
a) LTQ008 – LTQ230
The LTQ008 – LTQ230 Series are quarter-turn, electric industrial service actuators delivering up to 20,350 in-lb of
torque with voltages ranging from 230V to 575V 3-phase with on/off or proportional control modes. These
NEMA 4X and IP67 compliant units are equipped with two volt-free Form A auxiliary switches rated at, up to,
10A 250VAC, torque switches, and a standard clutch-free, manual-override handwheel. Additionally, these
units feature two ¾” EMT entry ports with sealed cable glands and a raised visual position indicator, as
standard. Users have the option to customize these units with the following features: motor control centers,
local control stations, IP68 submersible, battery backup, and interchangeable ISO5211 flanges and drives. This
series is ISO5211 compliant, mounting with double, square female drive inserts.
b) Control Station
Local Control Stations (LCS) provide a means to select Local or Remote control of a valve or damper
actuator. The LCS offered on the 008-203 sizes (LL) features unique capabilities, LED feedback, and a human-
machine interface.
3.1.1 Type LL (LED type)
This is a NEMA 4/4X and IP67 (optional IP68) type, rectangular enclosure, that is integral to the actuator
housing. This type contains two non-intrusive (magnetic) knob switches for mode and position control. This
version also employs an LED panel with five, bright LEDs mounted behind the glass with indicators for
actuator operations. The two rotary control knobs provide the user with the ability to operate the actuator
in a normal (REMOTE) mode where the actuator responds to control signals from a BAS, PLC, or other
control device. Or the user can elect to operate the actuator in a LOCAL mode where the user can control
the positioning of the actuator while standing at the device. This allows opening and closing of the
actuator (valve) to test for operation and to perform maintenance, or other function, without relying on
radio communication to command the automation system to position the actuator. The five LEDs provide a
visual indication of the position and status of the actuator with indicators for open, close, remote, local,
and fault. Open (green) and close (red) flash when the actuator is moving CCW (90°) or CW (0°),
respectively, and they remain lit upon reaching the end-of-travel. This version is available on the LTQ008
through the LTQ203 Series for all 3-phase voltage actuators.
