3500/42 Operation and Maintenance
General Information
3
I/O Modules with Barriers
The primary purpose of the 3500/42 monitor is to provide 1) machinery protection
by continuously comparing current machine vibration against configured alarm
setpoints to drive alarms and, 2) essential machine vibration information to both
operator and maintenance personnel. Alarm setpoints are configured using the
3500 Rack Configuration Software. Alarm setpoints can be configured for each
active proportional value and danger setpoints can be configured for two of the
active proportional values.
When shipped from the factory, the 3500/42 is delivered unconfigured. When
needed, the 3500/42 can be installed into a 3500 rack and configured to perform
the required monitoring function. This lets you stock a single monitor for use as
a spare for many different applications.
2.1
Triple Modular Redundant (TMR) Description
When used in a TMR configuration, 3500/42 monitors and Proximitor/Seismic
TMR I/O Modules must be installed adjacent to each other in groups of three.
When used in this configuration, two types of voting are employed to ensure
accurate operation and to avoid single point failures.
The first level of voting occurs on the TMR Relay Module. With this voting, the
selected alarm outputs for the three monitors are compared in a 2 out of 3
method. Two monitors must agree before the relay is driven. Refer to the
3500/32 & 34 Relay Module Operation and Maintenance Manual for more
information on this voting.
