What level of main reservoir pressure triggers the flashing "uncouple" button?

The main reservoir pressure that triggers the flashing "uncouple" button is less than 750kPa. This is crucial for safety and operational integrity in traction systems. The mechanism behind this is that a drop in pressure signals a potential issue, indicating that the system may not be functioning correctly or that there is a risk of failure. Thus, this pressure threshold serves as an alert to operators that immediate action may be necessary to address potential safety concerns or equipment malfunctions.

Setting the trigger point at less than 750kPa ensures that any operational issues are addressed before they escalate, as this pressure represents a critical level below which the system's efficiency and safety could be compromised. By adhering to this standard, operators can maintain more effective control of the traction equipment and minimize the risk of accidents or performance failures.
