Deadman Timer System

Description: The Deadman Timer System is a safety control device designed to ensure that an operator remain actively engaged during fuel transfer, loading, or any critical operation.
If the operator fails to press or hold the control within a set time period, the system automatically shuts down pump valves, preventing overfilling, spillage, or unattended operation.
This system enhances safety, compliance, and operational control in fuel handling, tanker loading, and industrial automation processes.
