Actuator does not work
LED does not lights
Actuator does not work
LED ligths red
Actuator does not work
LED lights green
Acuator does not work
LED is red blinking
Y-drive in the 3-pos mode can not gear
into intermediate positions
Actuator sits diagonally on the squared
damper shaft
A modulating actuator (Y) works with
reduced angle of rotation and already
reaches its end positions before 0 V/4
mA, respectively before 10V/20mA.
LED flashes irregularly and actuator
does not work

l No power supply attached
l The actuator is operated beyond ex-prevention
ambient temperature specifications and the internal
temperature sensor did irreversibly shut down
operations
l The actuator is operated by a too high ambient
temperature and the internal temperature sensor
responded
l 3-Pos control signal is wired on both entrances
l Required torque is greater than actuators torque
l Control signals are not attached or attached on a
wrong conductor
l Actuator is incorrect mounted and is blocked by an
external stop unit
l Interchanged supply lines
l The actuator has been mounted by temperatures
of less than -20°C and did not reach is operating
temperatur of at least -20°C.
l The conversion of constant mode on 3-pos-modus
was not set
l The actuators have an angle of rotation of 95°
inclusive 5° pre-tention. While assembling the pre-
loading was not considered
l At start up no self adjustment of angle of rotation
was accomplished
l Actuator does not receive sufficient supply voltage
l Cable to long, voltage drop in the supply line to large
E X P L O S I O N P R O O F
l Attache power supply and turn on
l Because of inadmissable operation the actuator drove out of safety
relevant reasons into an irreversible condition and must be exchanged.
Accompanying new installation the ambient temperature has to be
reduced accordingly
l Shut off actuator and let temperature decrease, reduce ambient
temperature by suitable measures e.g. ventilation or other mounting
position of the actuator
l Readjust / correct circuit
l Adjust a higher torque at the actuator if possible otherwise exchange
for a type with higher torque.
l Examine rule and adjusting signal in accordance with attached diagram
l Dismount actuator and testdrive without load for operability. Install
actuator accordingly that the power transmissions runs without external
blockade or torsion
l Wire 1 must be (-, N) and wire 2 (+, L)
l Ensure that a constant voltage supply on conductor 1--2 is existing.
l Wait until the required operating temperature is achieved by the actuators
internal heating system.The actuator will start operating independently
l Recalibrate the actuator in accordance with assembly instructions
l Dismount actuator of the damper, use the enclosed socket wrench to
draw up approx. 5° over the hand operated control device before
remounting on the damper shaft. Consider additional information
ME-M of the assembly instructions
l Accomplish self adjustment of angle of rotation in accordance with
assembly instruction
l Increase line cross section or increase tension at the transformer/power
suply unit
l Increase line cross section or increase tension
