1 MODELS COVERED BY THIS DOCUMENT The present manual is referred to following products: Acme screw linear actuators: ACL2 150 – ACL2 163 – ACL2 180 Ball screw linear actuators: ACL2 150B – ACL2 163B – ACL2 180B 2 IDENTIFICATION OF THE MANUFACTURER AND THE PRODUCT 2.1 Description of the product...
2.3 Identification of the product Every linear actuator is provided with a nameplate, as shown below, which allows the product identification and gives technical information about the product. Figure 2.2 – Identification nameplate Product description (the mining of symbols and their sequence are indicated on the catalogue);...
ACL2/ACL2 163B ACL2/ACL2 180B Mass (actuator 100 mm stroke length, without [kg] motor, with lubricant) Extra-mass [kg] for each additional 100 mm stroke length In case of doubt, consult SNT to get the appropriate information and prevent any kind of damage!
Modification of parts of the actuator or replacement of components with different and non-original parts is not permitted. The replacement of components with original spare parts is carried out only by SNT. Any different use is to be considered improper and therefore potentially dangerous for the safety of the operators, as well as such as to void the contractual guarantee.
4.1.2 Standard operating conditions The actuator must be used in an environment whose conditions comply with the provisions of SNT. The works necessary for obtaining and maintaining that conditions are in charge of the owner and, where applicable, are in charge of the end user.
6 INSTALLATION The operations described in the paragraphs of this chapter provide both electrical and mechanical connections of the actuator, as well as the execution of test motions at reduced speed and motor torque or with small displacement steps. 6.1 Safety warnings MOTORS CANNOT BE CONNECTED DIRECTLY TO THE ELETRICITY GRID.
6.2 FCE electric stroke limit switches The ELECTRIC STROKE LENGTH LIMIT DEVICE allows to limit the actuator stroke length avoiding to reach the extreme positions (mechanical stop) and preventing damage. The FCE device consists of 2 normally closed electric switches installed inside a sealed box made in engineering plastic or aluminium alloy.
6.3 FCP inductive proximity stroke limit switches The INDUCTIVE PROXIMITY STROKE LIMIT SWITCHES allow the actuator to stop before reaching the internal mechanical stop avoiding damage. If intermediate sensors are present, they can be used to fix intermediate positions along the actuator stroke length. The inductive proximity stroke end switches are fixed directly on the actuator outer tube in the required position.
6.4 Rotary encoder ENC.4 Encoder ENC.4 – TECHNICAL FEATURES Transducer type Hall-effect encoder, incremental, bi-directional Resolution 4 pulses per revolution PUSH-PULL Output 2 channels (A and B, phase difference 90°) Input voltage 8 ÷ 32 V DC Max commutable current I 100 mA with load connected to 0 and I = 100 mA: 4.6 V...
Check if the push rod shifting direction is compatible to the indications on the control unit, by powering the electric motor on VERY BRIEFLY. Figure 6.5 – Push rod shifting directions If the push rod shifting directions are not compatible: invert any wire pair (U1 V1, or U1 W1, or V1 ...
• Fit the actuator to the plant in order to have ONLY axial load applied to the actuator. • Check the correct alignment between front and rear pins: they must be PARALLEL. • Check the correct alignment between the actuator and the moving parts. Figure 6.7 –...
7 COMMISSIONING AND USE Linear actuators are supplied lubricated and ready to be used. Before to start commissioning and activation, the following checks must be carried out: Shifting direction check Check if the push rod shifting direction is compatible to the indications on the control unit, by powering the electric motor on VERY BRIEFLY.
Linear actuators ACL2/ACL2 B series are supplied lubricated, with lubricants indicated in the table below. PUSH ROD GUIDE ACTUATOR GEARBOX LINEAR DRIVE REAR HINGE ACL2 150 Grease (NLGI 00 DIN 51818): Grease (NLGI 2 DIN 51818): ENI Grease SM 2 AGIP Grease SLL 00 Also suitable: ACL2 163...
Every 2 months time interval: visual inspections of actuator conditions, cleaning of dirty parts of the actuator. In case of lubricant leakage, contact SNT. Note for ACL2/ACL2 B 150: the rear hinge material is auto-lubricated and it does not require ...
9.1 Linear drive lubrication WARNING! THE PLANT MUST BE STOPPED BEFORE BEGINNING ANY MAINTENANCE OPERATION. Before to start relubrication, put the actuator in extended position (La – see Fig. 6.6) Relube the linear actuator using proper grease nipples, as shown on Fig. 9.2 ...
9.2 Push rod guide lubrication WARNING! THE PLANT MUST BE STOPPED BEFORE BEGINNING ANY MAINTENANCE OPERATION. Relube the push rod guide using proper grease nipple, as shown on Fig. 9.3. Grease nipple type: DIN71412 M6. Push rod guide grease nipple Figure 9.3 –...
