Introduction Thank you for choosing our product. We would like to give you some information about the correct installation and use of your SEKO apparatus. We recommend reading the instructions carefully before installing and starting the apparatus; SEKO cannot be held responsible for any damage caused by failure to observe the contents of this manual. -
Page 3: Description
Support flange Front case The SEKO actuator ATR-05 is an electromechanical appliance that can receive a command signal and make an output shaft rotate, by a proportional number of revolutions to the command received, based on an electronically pre-programmed full scale. -
Page 4: Safety Instructions
On the ATEX certified actuator, the rear case and the flange form the flameproof case, inside which there is a cut-out heater, which guarantees the operation of the system at the correct temperatures and prevents the formation of condensate inside it; the heater can also be assembled on the standard version upon request. -

Page 7: Torque/Speed Curve
5.1 Torque/speed curve Figure 4: Characteristic curve Fig.4 shows the values of torque available to the actuator output shaft at the various rotation speeds. As indicated in 8.2, the value of the torque supplied to the actuator can be set by the user by changing the parameter of the programming menu. -
Page 8: Power Supply
5.2 Power Supply The apparatus can be powered in three different ways. Main power supply 100-240 Vac. Secondary power supply 100-240 Vac. Auxiliary power supply 24Vdc protected not insulated. The power supplies can all be connected to the apparatus. The power supplies can all be active at the same time; based on the power supplies present, the system behaves as follows: Main Secondary... -

7.2 Electrical installation 7.2.1 General information Failure to respect the safety regulations and warnings contained in this manual may lead to serious damage to the health of the people exposed. The motors and electrical components must be connected in accordance with the local laws and only by qualified staff. -
Page 11: Internal Wiring
For the power supply a reinforced wire, such as FG7ORAR 7 with 7 poles from 9 to 18 mm minimum section 1.5 mm recommended (especially for the ATEX version). 7.2.3 Internal wiring Fig.6: Terminal Board Figure 6 represents the connection diagram of the actuator; the same diagram is shown on a special sticker on the protection screen inside the case. -
Page 12: Programming
PROGRAMMING The actuator has a 4-digit, 7-segment display. The calibration can be carried out when it is switched on and also during operation, forcing the input by pressing the Cal key. 8.1 Programming menu Press the ENTER key for three seconds to enter the programming menu. The following indications are useful for reading the diagram: Use the UP-DOWN keys to scroll through the main menu;... - Page 13 Enter Password Figure 7: Programming menu diagram SA00136004 Rev. 2.1...

Page 15: Calibration During Operation
At this point calibration has started. Rotate the actuator manually until 100% is reached, using the UP and DOWN keys, and as soon as 100% is intercepted, press the Enter key. The display will show: (First MEM) flashing and after a few seconds the following will appear on the display (Step 1 Point 2): Rotate the actuator until the desired 0% is reached, still using the UP and DOWN keys and then press the Enter key. -
Page 16: Unblock Condition During Calibration
8.5 Unblock condition during calibration During calibration the system blocks automatically should the rotation set by the operator exceed the physical limits of the system. Then the message (Extra STRoke) appears: The operator can perform the unblock operation by pressing the Enter key and (UNBlocked) appears. And at this point the operator can manually move the actuator using the UP/DOWN keys until it returns into the correct operating field. -
Page 17: Optional Actuator Activation Conditions
There is an output on the apparatus to allow an externally powered relay to be driven, which is triggered in alarm conditions. In the event of lack of power supply it is possible to adjust the stroke manually based on the indication provided by the mechanical vernier index. -
Page 18: Password Modification
Torque modulation parameter It is possible to adjust a parameter that modulates the torque. This parameter can have a value from 0 to 4, where 0 means disabled. As this parameter increases the apparatus changes from smooth behaviour to strong behaviour. End positioning approach step parameter. -
Page 19: Visualization Of Alarms
10.3 Visualization of alarms The system can visualize four types of alarms. A permanently lit green LED or red flashing LED is shown for all the alarms. If you enter programming mode in the presence of an alarm, the red LED continues to flash to show that the alarm condition remains. -
