The Sci/ERA Standby Drive and Alarm System is designed to provide
the utmost in protection against Roller Apparatus failure. Major
features include a digital display of bottle speed, a maintenance-free
battery and charging system, a motion detection system, internal
and external alarms, and dual heavy-duty drive system. The control panel
contains all switches, indicators and alarms logically arranged into
functional clusters. The Standby Drive and Alarm System protects against loss
of cell cultures due to power failures, inadvertent power cord disconnection
and "brown outs" with a auxiliary maintenance-free battery and charging system.
This backup system may also be engaged to keep cultures rolling during transit,
feeding and harvesting; a key switch silences the internal audible alarm during
such handling. The motion detector system continuously monitors roller motion.
In the event of failure due to the primary drive circuit, motor, or belt
breakage both the internal and external alarms are activated, and the
backup drive system takes over.
Bottle Speed: 0.1-4.0 RPM Standard or 0.07- 2.2 RPM when specified on the order
