	ELECTRIC Actuators EK range The actuator does not work (the valve does not move). The actuator does work only in one direction. The valve does not open and close completely. The visual position indicator is inverted regarding valve's position. ER STANDARD range The actuator does not work (the valve does not move). The actuator moves only in one direction. The electrical limit switches for opening or closing does not work. The visual position indicator is inverted regarding valve's position. The 24V actuator jams from time to time then works again after some times. VR/VS range The actuator does not work (the valve does not move) The actuator moves only in one direction. The electrical limit switches for opening or closing does not work. The visual position indicator is inverted regarding valve's position. Options EBS/EBT The failsafe safety bloc does not work. The failsafe safety bloc has worked but works no more.


Top	ELECTRIC Actuators All actuators The actuator does not work (the valve does not move). Check the power supply. Check the wiring. Check the manual functioning. There should not be a hard point.

Top	ELECTRIC Actuators All actuators The valve does open and close completely. Check the manual functioning. There should not be a hard point. Check the setting of electrical motor limit switches cams.
Top	ELECTRIC Actuators All actuators The visual position indicator is inverted regarding valve's position. Chek the mounting of valve and actuator.
Top	ELECTRIC Actuators All actuators The electrical limit switches for opening or closing does not work. Check the setting of auxiliary of limit switches (there should be adjusted with a small in advance of the electrical motor limit switches.
Top	ELECTRIC Actuators ER 24V range The 24V actuator jams from time to time then works again after some times. Check the working rates. If the working rates are too high, the safety system (thermal fuse) will automatically shut off the power supply for a certain time. Check your voltage. It should not exceed 24V (we advise a stabilized power supply), if higher the safety system (thermal fuse) can at an untimely moment break out. Check the air temperature (60° C. at least).
Top	ELECTRIC Options EBT/EBS The failsafe safety bloc does not work. Check the power supply. Check the fuse (EBT). Check the power supply signal LED (EBT). Check the battery (respect the in the Instruction of Use advised loading time). Check the wiring (see Instruction of Use).
