2.1 Technical characteristics

• The electric actuator VB015 has the heating resistor standard, always supplied.
• Both the versions of the actuators, 12-24V ac/dc and 100-240Vac, have 24V motor. If the actuator has to face a torque higher than the foreseen
maximum torque then the actuator block it self and keep a state of “stress” from the electronic circuit of power control. 1 2 3 5 6
• The options at 12V and 24V AC/DC, in case the torque go over the maximum one foreseen, are projected to block automatically the actuator by taking off
the electrical supply to the motor.
• This status keeps the electric actuator steady until a new impulse will be processed.

These are 2 auxiliary contacts of limit switches (free contact SPDT) available on the terminal block “G” which is possible to connect to give signals to the The procedures to adjust the actuator stroke are as follows: • After making the proper connection, please proceed to the assembling of cover “A”, by paying close attention not to hit any electronic parts.
end user. • Re-assemble the position indicator “B” on “OPEN” blocking it by screw “C”.
• To connect to the terminal block “G” between the contacts: 1. Take care there is not electrical supply. • Make sure that the tightening of cables is secure, by screwing the gland “E”.
• “7” and “8” to get the signal of closure. 2. Remove the upper cover of the actuator (see instructions point 4). • Finish the closure of the cover “A” by screwing in the fasteners “D”.
• “11” and “12” version 12-24V ac/dc - “10 and 11” version 100-240V ac to get the signal of opening. 3. Take care that the device to be automatised (example: valve) is on “OPEN” position.
4. The electric actuator VB015 has 2 discs camsholder, the upper one “2”orders the micro limit switches to control “open” and “closed”, while the bottom 5.0 Emergency operation
one “1” orders the auxiliary limit switches used to give the signal of opening and closure. For each camsholder there is a black cam, (opening rotation)
and a white cam (closure rotation), the two cams are tighted by a screws “3”. The electric actuator VB015 has an external handwheel “B” with position indicator, by which is possible to operate manually the closing and opening
operations.
WARNING: during the installation it is reccomended to verify the alignment of the auxiliary limit switches by using a multimeter/tester. The manual operation operates by working on the external handle “H” by turning it to the position “MAN”, at this point is possible to make the manual operation

Attention: do not operate the manual override when the actuator is working.

6.0 Maintenance

These electric actuators do not need of any format maintenance.

The internal lubrication is sufficient for the whole life of the actuator.
7 8 9 10 11 12 To get a good cleaning of the external parts, we suggest to use a light detergent with low level of chemical aggressiveness.
In case of damage or a problem in operation, we recommand that you send the actuators back to Valbia for inspection.

necessary to use a Valbia electric actuators whose range has a torque of at least 25% over the valve maximum torque.
WARNING: for command PIN 1-2-3 it is recommended:
• use optoisolated static impulse connection; WARNING: do not operate the manual override when the actuator is powered.
• use proper cables and precautions on the control system to minimize electromagnetic interference.
