7. Residual risks
Risks for persons:
under the following circumstances, the safety of persons and material objects can be endangered:
• if the safety devices on moving parts have been removed.
• if any damage to the control system is not repaired immediately.
• if untrained personnel are working on electronic parts.
• if the machine is activated before being secured properly to a wall or pillar (for testing or demonstration reasons).
The following points summarise further measures aimed at protecting against personal and material risks:
• ensure that the machine, the control devices and the brushes are not damaged during transport and installation.
• mount the machine in a place that is well ventilated and free from electromagnetic interference.
• the personnel responsible must be trained in the use and maintenance of the machine.
Risk for animals:
under the following circumstances, the safety of the cattle can be endangered:
• the animals have collars and/or tail hairs that are too long.
• the animals' hides are more than 3 cm long.
• the customer has not protected the current-carrying parts (cables) adequately / at all against biting.
8. Description of faults and troubleshooting
A number of functional errors are listed below which can occur as a result of wear, machine defects, particularly challen-
ging operating conditions, incorrect operation or a lack of maintenance. Methods are also described which are aimed at
finding and eliminating the problems:
Caution:
Work on voltage-carrying parts only when the power supply has been disconnected!
1
Cleaning brush will not turn on
2
F1 fuse repeatedly defective in a
short period
Important: the length of the cattle's tail hairs must not exceed 3 cm!
Power supply missing
Sensors not in position
Mains voltage too low
Mains voltage too high
Control module defective
Blown fuse
Control module defective
_check power connection
_check voltage
_check connecting cable / motor cable
_check temperature switch
_check tilt sensor
Display message: 2
_mains voltage <180V with 230V grid
_mains voltage <85V with 110V grid
Display message: 1
_mains voltage >270V with 230V grid
_mains voltage >140V with 110V grid
_replace control module
_check fuse, replace if necessary
_replace control module
