Error/Symptom Reason Solution
M.EZ-01.03-M-en-extra-info EL
08-apr-2010
Error indication
Actuator does not work
LED ligths red
l The actuator is operated by a too high ambient
temperature and the internal temperature sensor
responded
l Shut off actuator and let temperature decrease, reduce ambient
temperature by suitable measures e.g. ventilation or other mounting
position of the actuator
02
Actuator does not work
LED lights green
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 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)
03
05
06
07
Y-drive in the 3-pos mode can not gear
into intermediate positions
l The conversion of constant mode on 3-pos-modus
was not set
l Recalibrate the actuator in accordance with assembly instructions
08
Actuator sits diagonally on the squared
damper shaft
l The actuators have an angle of rotation of 95°
inclusive 5° pre-tention. While assembling the pre-
loading was not considered
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
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.
l At start up no self adjustment of angle of rotation
was accomplished
l Accomplish self adjustment of angle of rotation in accordance with
assembly instruction
LED flashes irregularly and actuator
does not work
l Actuator does not receive sufficient supply voltage
l Cable to long, voltage drop in the supply line to large
l Increase line cross section or increase tension at the transformer/power
suply unit
l Increase line cross section or increase tension
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 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
Actuator does not work
LED does not lights
01
Acuator does not work
LED is red blinking
04
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 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
