SECTION 2: SAFETY INSTRUCTIONS T200 User's Manual
PAGE 2-9
Safe-guards should be an integral part of a workcell design, installation, operator training, and operator procedures. A
computer controlled system may activate remote devices under program control at times not anticipated by personnel. It
is critical that safeguards be in place to prevent personnel from entering the workcell whenever equipment power is
present. Moog highly recommends the use of workcell safety features such as light curtains, safety gates or safety floor
mats to prevent access to the workcell while power is present. Computer controlled systems have various
communication features which may aid the user in constructing system safeguards, including:
• emergency stop circuitry
• binary input and output lines
• spare system-controlled user lines
The emergency power-off circuitry of a computer controlled system is generally capable of switching external power
systems, as well as detecting intrusion signals from safety barriers.
All personnel must observe sound safety practices during the operation and testing of all electrically powered
equipment. To avoid injury or damage to equipment, always remove power BEFORE attempting ANY repair or upgrade
activity.
- The equipment described in this user’s guide operates at voltage levels
which can exceed 400 volts d.c. and/or 230 volts a.c. These levels are a potential source
of severe electrical shock. DO NOT remove or replace any assemblies, subassemblies or
components with the primary power present. To avoid possible personal injury or
equipment damage, always remove power BEFORE attempting repair or upgrade
procedures. Wait at least 5 minutes after power shutdown to ensure power supply
capacitors have discharged. Then using a voltmeter, check for safe levels across all high
voltage power terminals.
