Secure Access Features & Benefits

Secure Access Hydraulic Valve Lockout System

The MEYER Secure Access Lockout System enables administrators to set authorization codes for the operation of accumulators. This capability provides administrators with a flexible, yet secure way to assign individual user permissions and set date and hours-of-operation restrictions. This inventive system is the only lockout control device that incorporates programmable accountability, control, and traceability into your risk management design.

The Secure Access Hydraulic Valve Lockout System ensures accountability by recording lockout system-engagement history with a time and date stamp. This identifies when, and by whom, closing unit valves were locked and unlocked. Despite power shortages, the system safely stores and protects data, which is accessible by connecting the laptop that is provided with the programmable system.

The programmable Secure Access Hydraulic Lockout System also features an override control that allows an unauthorized user to unlock valves in an emergency. When engaged, the emergency override will trigger alarms—in the form of a flashing light and warning horn—that will continue until turned off by the job administrator.
