When the monitored material increases above a certain setting, what will happen to the contacts represented by the symbol?

When the monitored material increases above a certain setting, the contacts represented by the symbol will close. This indicates that the system is designed to respond to the monitored condition by completing a circuit or allowing current to flow once the specified threshold is reached.

For example, in many monitoring systems, when a sensor detects a change, such as a temperature rise or a pressure increase, it triggers a response. If the design is set such that contact closure indicates an alert or action (like activating an alarm or starting a cooling system), then it would be expected that once the monitored condition exceeds the set point, the contacts close to complete that action.

This mechanism is common in various applications, where closing contacts signify an "on" state or an active response to a condition that needs attention or further action, ensuring appropriate measures are taken in response to the monitored material.
