EcoTrim ET-1024 System
1 Introduction
1.2 System Overview
• Three button operator station:
–Dual channel “Cycle Start” button
–Dual channel “E-Stop”
–Single channel “Auto/Manual” switch
• Functional Safety Unit (FSU):
–Responsible for monitoring the MSR rotary table to ensure no
external motion occurs (via “Standstill monitor” function while the
light curtain is broken.
• Omron G7SA Force Guided Relays:
–Monitors FSU “At Side A” and “At Side B” outputs to generate dry
contact connections for use in the external E-Stop logic.
1.2.3.4 Safety Logic Implementation:
1. In “Play Mode” and “Teach Mode”, FSU-based “Axis Range Limit”
functions generate “At Side A/B” outputs which prevent the MSR
positioner from moving out of “At Side A” or “At Side B” anytime the
light curtain is broken.
2. In “Play Mode” the DX200 monitors the “Safety Gates,” closed
ensuring someone is not accessing the work cell while in “Play Mode”.
3. The FSU is not for preventing robot collisions with either the safety
fence or the MSR positioner.
