How to modify the pump stop parameter on the controller?

Examine the parameters of the TRIGGER block to adjust the pump's behavior by defining different on and off thresholds. Adjusting the parameters of a controller can vary considerably depending on the specific model and configuration. It's important to refer to the appropriate documentation or consult a professional for precise instructions.

How does a Trigger function on a Crouzet PLC?

The Trigger is a functional block that acts as a double comparator. Its role is to limit the number of starts and stops of a system (such as a circulator) by defining two distinct thresholds: SH (High Threshold) for switching from stop to run, and SB (Low Threshold) for switching from run to stop. The Trigger's output remains active as long as the temperature is above the low threshold and only becomes active when the value exceeds the high threshold. This prevents rapid oscillation phenomena (repeated starts/stops) when the measured value fluctuates around a single setpoint. It is recommended to maintain a gap (delta) of at least 2 between the two values for optimal operation.

How does a Trigger function block work on an automaton?

The Trigger is a function block that acts as a dual comparator to limit system starts and stops. It uses two thresholds: SH (High Threshold) for off-to-on transition and SB (Low Threshold) for on-to-off transition. The output remains active as long as the value is above the low threshold and only activates when it exceeds the high threshold, preventing oscillations. A difference of at least 2 between the thresholds is recommended.

How does a Trigger function on a Crouzet PLC?

The Trigger is a functional block that acts as a double comparator. It limits the starts and stops of a system by defining a High Threshold (transition from stop to run) and a Low Threshold (transition from run to stop). The output remains active as long as the value is above the Low Threshold and only activates when the value exceeds the High Threshold, thereby preventing oscillations. A difference of at least 2 between the values is recommended.

How does the Trigger functional block work on a Crouzet PLC?

The Trigger is a functional block that acts as a double comparator, limiting the starts and stops of a system. It uses two thresholds: SH (High Threshold) to activate the system, and SB (Low Threshold) to deactivate it. The output remains active as long as the measured value is above the low threshold and only becomes active when the value exceeds the high threshold. This prevents rapid oscillations. It is recommended to maintain a gap (delta) of at least 2 between the two values.

How does a trigger function on a Crouzet PLC?

A trigger acts as a double comparator to manage system starts and stops. It uses a High Threshold (SH) to switch the system to 'on' and a Low Threshold (SB) to switch it to 'off', which prevents rapid oscillations when values fluctuate.

How does a Trigger work on a Crouzet automation system?

The Trigger is a functional block (present in the FBD tab) that acts as a double comparator. Its role is to limit the number of starts and stops of a system (like a circulator) by defining two distinct thresholds: High Threshold (SH) for switching from stop to run, and Low Threshold (SB) for switching from run to stop. The Trigger's output remains active as long as the temperature is above the low threshold and only activates when the value exceeds the high threshold. This prevents rapid oscillation. It is recommended to maintain a gap (delta) of at least 2 between the two values for optimal operation.

How does the Trigger function block operate on a Crouzet controller?

The Trigger acts as a double comparator to manage system starts and stops. It uses a High Threshold (SH) to switch from stop to start and a Low Threshold (SB) to switch from start to stop. This prevents rapid oscillations by maintaining the active state until the value drops below the low threshold.
