1.5 POTENTIAL EXPOSURE HAZARDS
The following section will cover potential exposure hazards, which may occur while
operating the spin processor system.
NOTE: This section should be READ and UNDERSTOOD before using the spin
processor.
1.5.1 ELECTRICAL HAZARDS
WARNING
240/115 Volts AC is used throughout the system. Do not attempt to
troubleshoot or make repairs. (Refer to Section 2 for spin processor
power requirements and main circuit breaker information.)
Caution
: an extreme electrical hazard will exist if this system is immersed in liquid. The
system must not be located where it could be accidentally knocked into any open liquid
bath. An earthquake-proof base can be supplied for any system.
Electrical components are located internally, and electrical power is distributed
throughout the spin processor system. Access can only be gained by removal of the
bottom panel, which is secured by screws. Only LTC factory trained, qualified
technicians should be permitted to work on an uncovered machine. Use all precautions
and safety measures characteristically taken with AC and DC circuitry.
The spin processor should be locked and tagged out according to the procedure
outlined below before any maintenance or service is performed.
Maintenance tasks are categorized by “TYPE TASK” as described below. The spin
processor has no tasks that are above Type 2. The maintenance manual identifies
tasks that may have electrical energy present using the following conventions:
Type 1 - Equipment is fully de-energized (electrically "cold"). Lockout and tag-out
procedures should be used.
Type 2 - Equipment is energized. Live circuits are covered or insulated. Work is
performed at a remote location to preclude accidental shock.
Type 3 - Equipment is energized. Live circuits are exposed and accidental contact
is possible. Potential exposures are less than 30 volts, 42.2 volts peak,
240 volt-amps, and 20 Joules.
