AUMA SAR 07.2 Manual

Information For "SIL seating" = "forced limit seating in end position", the seating is performed
via limit switches in the end position. Since each switch has a hysteresis, the actuator
leaves the end position prior to limit switch release. Consequently, there is a marginal
range of actuator positions to the safety position, for which the limit switch is still
operated when leaving the safety position while the Safe ESD function is NOT
available. In this case, safety function triggering leads to actuator standstill. If the
range in question is approached from the opposite direction, this limitation does not
apply. In general this range is relatively low. However, for unfavourable configurations
(low number of turns per stroke), this range can amount to more than 10 % of the
total stroke.
Should within the framework of unfavourable conditions the effect described above
represent an unacceptable limitation for the safety function, we recommend applying
the configuration "forced torque seating in end position" or "no seating" for safety
operation.
Power supply
Information The plant operator is responsible for power supply.
3.2. Configuration (setting)/version
Configuration (setting) of safety-related functions is adjusted in the factory during
controls assembly and validated during final inspection. Subsequent modification of
the configuration by the plant operator is not permissible.
General functions are set as described in the Operation instructions or the Manual
(Operation and setting) AUMATIC AC 01.2.
Configuration of safety-related functions is listed in the order-related technical data
sheet.
