Max Collisions (V-Series)

Max Collisions (V-Series)

Possible causes

• The operator is encountering an obstruction and has reached the pre-set number of allowable collisions

• The controller collision force is set too sensitively

• Number of allowable collisions set to a low value, e.g. 1

• Excessive wind loading

• Damaged encoder

• The operators in a double-leaf installation are different versions, resulting in excess current draw from one operator’s encoder sensor

• Dimensions for A, B, and C are incorrect

• Faulty DOSS harness. Repair work of this nature should be conducted by a qualified technician

• Loose drive and/or sensor connections

• Gearbox not fully engaged


Solutions

• Ensure that the gate is running smoothly and that there is nothing physically hindering the trajectory of the gate

• Increase the collision force (Menu 2: Safety)

• Increase maximum collisions value to a higher number, typically 4

• Ensure A, B, and C dimensions are correct

• Ensure that both operators in a double leaf installation are the same version (e.g. v2 - VECTOR2)

• Replace faulty DOSS harness. Repair work of this nature should be conducted by a qualified technician

• Check battery, motor terminal and sensor connections; check connections on the controller at any junction points between the operator and the controller

• Ensure that operator is fully engaged by turning the key fully clockwise

• Replace faulty DOSS encoder. Repair work of this nature should be conducted by a qualified technician

• As the encoder is mounted inside the actuator, it is preferable to replace the actuator
