Safety Summary
(continued)
• Process technicians are to be present when testing and operating process
objects.
• Never activate any System Initialization push-button if any uncertainty
exists regarding exactly what occurs within the system during initialization.
ALWAYS CHECK FIRST .
• Remember at all times, that the control system can be controlled from a
remote engineering station, connected at another node via Control
Network.
• Remember, the AC 800M Controller will start automatically when voltage
is applied.
Taking steps to bring the process to a safe state, provides an improved level of
safety when power supplies, communication links or parts of the control system
fail. Such steps may require, for example, the installation of valves or relays that
automatically return to a fail-safe position.
Product Safety
The following safety rules must be observed at all times:
• To avoid discharging static electricity, ground both yourself and any tools
before handling printed circuit boards, batteries, memory cards, and other
sensitive pieces of the equipment
• All electronic devices are sensitive to ESD (electrostatic discharge). To
avoid accidental damage while handling printed circuit boards, it is
recommended to wear a wrist strap, grounded to the chassis. The strap must
have a built-in protective resistor
• Anti-static, conductive plastic bags must be used for storage and transport
of PC boards in transit.
