BS EN IEC 63327:2021 pdf download – Automatic floor treatment machines for commercial use — Particular requirements
This requirement is not applicable to type 1 machines not exceeding a speed of 1 ,5 km/h and to automatic floor treatment machines during the docking process to the docking station. Compliance is checked by functional test. Test duration is 5 min or less if the machine moves away from the obstacle.
7.8 The machine shall monitor the operating status of all safety-related control parts of the control system before starting and during operation. Any detected failure in the safety-related parts of the control system shall result in a stop category 0 or stop category 1 with the driving wheels in a locked state. The machine shall require the intervention of the operator to restart. The safety-related parts of the control system are the relevant parts of the safety-critical functions (SCFs) identified in Table 1 . Compliance is checked by an evaluating system in accordance with Table 1.
7.9 The machine shall avoid contact with any static objects that enter the stopping zone. When any obstacle described in 5.1 enters the stopping zone, at least a stop category 2 or obstacle avoidance shall be initiated. This requirement is not applicable to type 1 machines not exceeding a speed of 1 ,5 km/h and to automatic floor treatment machines during the docking process to the docking station. When a stop category 2 is achieved and the machine is at rest, the contact zone sensors may be disabled.
NOTE When the obstacle is removed, the machine can resume movement automatically unless contact with the obstacle is made. Compliance is checked by the following test: The machine is driven toward the test obstacles, at both confined space speed and rated automatic speed. The obstacles are placed outside of the stopping zone ahead of the machine. The machine shall avoid contact with any objects when entering the stopping zone.
When any obstacle described in 5.1 enters the stopping zone, at least a stop category 2 or obstacle avoidance shall be initiated. Each obstacle shall be tested separately. Test obstacle 1 shall be laying down and at 0°, 45°, and 90° to the path of the machine, at a range greater than the machine safe stopping distance, and positioned at the left-most (one- half the width of the machine from the centreline), right-most, and centre of the machine travel path. Test obstacle 2 shall be set vertically at a range equivalent to the machine safe stopping distance and positioned at the left-most, right-most, and centre of the machine path (see Figure 2 for obstacle positioning).
7.1 0 Following a stop category 2, each of the obstacles described in 5.1 is placed in contact with the machine at various locations representative of the contact zone. The machine shall not initiate motion, unless the system ensures during motion to brake on time to prevent further contact with the obstacle.
This requirement is not applicable to type 1 machines not exceeding a speed of 1 ,5 km/h and to automatic floor treatment machines during the docking process to the docking station. Compliance is checked by functional test. Test duration is 5 min or less if the machine moves away from the obstacle.
7.1 1 When either of the obstacles described in 5.1 enters the contact zone while the machine is moving, a stop category 0 or stop category 1 shall be initiated. This requirement is not applicable to type 1 machines not exceeding a speed of 1 ,5 km/h and to automatic floor treatment machines during the docking process to the docking station.
Compliance is checked by the following test:
The obstacle is moved in front of the machine’s direction of motion inside the stopping zone. The machine’s contact zone shall initiate a stop category 0 or stop category 1, due to anticipated contact with the obstacle. When the obstacle is removed, the machine shall not resume movement without operator intervention.BS EN IEC 63327 pdf download.
