The Redundant Safety Board is a microprocessor control monitoring system to independently check several critical safety issues as required by code.
The microprocessor receives position, direction of travel and velocity information from the IP8300+ perforated tape reader in the shaft-way. In addition to the tape reader, it also receives Slowdown Limits and Door Zone information. Force-Guided relays contacts are checked for proper operation. Uncontrolled motion is also checked.
