Preface Introduction The PL-6920/PL-7920 series (PL) of Panel Computers are multipurpose factory automation (FA) computers, which embody Pro-face’s latest, cost- effective architecture. Before using the PL, read this manual thoroughly to familiarize yourself with the PL’s operation procedures and functions.
Page 3: Essential Safety Precautions
• Do not create touch panel switches that are used to either control or to ensure the safety of equipment and person- nel. Mechanical switches, such as an emergency stop switch, a deadman (two-handed) start switch, etc., must be installed and operated via a separate control system. PL-6920/PL-7920 Series User Manual...
Page 4 • Read and understand Chapter 4 “Installation and Wiring” thoroughly in order to select an appropriate installation location for the PL. • Before either plugging in or unplugging a board or inter- face connector, be sure to turn the PL’s power OFF. PL-6920/PL-7920 Series User Manual...
Page 5 Do not use thinner or organic sol- vents. • Avoid exposing the PL to, or operating the PL in direct sunlight, high temperatures and humidity, and in areas where excessive dust and vibration will occur. PL-6920/PL-7920 Series User Manual...
Page 6 HDD stops spinning before turning on the power again (approx. 5 seconds). • When the PL unit's standard display is connected to the PL using the USB connection, wait three (3) seconds before turning the power ON again. PL-6920/PL-7920 Series User Manual...
