Important: Carefully examine the inside of the cylinder. If everything is in good condition, continue to replace the new 'O' rings, bushings, slide guides and washers included in the GESTRA BVA300 series maintenance kit before reassembling the actuator - see Section 5.4.3. -
Page 20: Fault Finding
6 Fault finding Before dismantling the actuator, consult the instructions given below: 6.1 Actuator with solenoid valve A If the actuator does not function check that: The valve is free to rotate. The actuator is of the correct size. The correct voltage is supplied to the solenoid (the valve coil is tagged with the correct voltage). Sufficient compressed air is available at the solenoid valve. - Page 21 With spring return actuators, check for misplaced or broken springs. If springs are broken, check the body for scoring. If the actuator and valve are free, reassemble the actuator and retest. If the unit still fails to operate, consult GESTRA. IM-P370-02-EN-ISS3 819763-03...
