1. Receiving and Handling Instructions
1.1 Receiving Inspection
Visually inspect the module for obvious shipping damage. If shipping damage is
apparent, file a claim with the carrier and submit a copy to Bently Nevada
Corporation.
1.2 Handling and Storing Considerations
Circuit boards contain devices that are susceptible to damage when exposed to
electrostatic charges. Damage caused by obvious mishandling of the board will
void the warranty. To avoid damage, observe the following precautions in the
order given:
Application Alert
Machinery protection
will be lost when this
module is removed from
the rack.
- Do not discharge static electricity onto the circuit board. Avoid tools or
procedures that would subject the circuit board to static damage. Some
possible causes include ungrounded soldering irons, nonconductive plastics,
and similar materials.
- Personnel must be grounded with a suitable grounding strap (such as 3M
Velostat No. 2060) before handling or maintaining a printed circuit board.
- Transport and store circuit boards in electrically conductive bags or foil.
- Use extra caution during dry weather. Relative humidity less than 30 % tends
to multiply the accumulation of static charges on any surface.

2. General Information
The 3500/42 Proximitor/Seismic Monitor is a four channel monitor that accepts
input from Proximitor and Seismic Transducers and uses this input to drive
alarms. The monitor can be programmed using the 3500 Rack Configuration
Software to perform any of the following functions: Radial Vibration, Thrust
Position, Eccentricity, Differential Expansion, Acceleration, and Velocity. The
monitor can receive input from many types of transducers including the following
Bently Nevada transducers:

3500/42 Operation and Maintenance General Information

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.

General Information 3500/42 Operation and Maintenance

The second type of voting is referred to as "Comparison" voting. With this type
of voting, the proportional value outputs of each monitor in the group are
compared with each other. If the output of one monitor differs from the output of
the other monitors in the group by a specified amount, that monitor will add an
entry to the System Event list. Configure comparison voting by setting
Comparison and % Comparison in the Rack Configuration Software.
Comparison: The enabled proportional value of the TMR monitor group that is
used to determine how far apart the values of the three monitors can be to
each other before an entry is added to the System Event List.
% Comparison: The highest allowed percent difference between the middle
value of the three monitors in a TMR group and the individual values of each
monitor.
For TMR applications, two types of input configurations are available: bussed or
discrete. Bussed configuration uses the signal from a single nonredundant
transducer and provides that signal to all modules in the TMR group through a
single 3500 Bussed External Termination Block.
Discrete configuration requires three redundant transducers at each
measurement location on the machine. The input from each transducer is
connected to separate 3500 External Termination Blocks.
2.2 Available Data
The Proximitor/Seismic Monitor returns specific proportional values dependent
upon the type of channel configured. This monitor also returns both monitor and
channel statuses which are common to all types of channels.
2.2.1 Statuses
The following statuses are provided by the monitor. This section describes the
available statuses and where they can be found.
Monitor Status
OK
This indicates if the monitor is functioning correctly. A not OK status is
returned under any of the following conditions:
Module Hardware Failure
Node Voltage Failure
Configuration Failure
Transducer Failure
Slot ID Failure
Keyphasor Failure (if Keyphasor signals are assigned to channel pairs)
Channel not OK
If the Monitor OK status goes not OK, then the system OK Relay on the Rack
Interface I/O Module will be driven not OK.

Alert/Alarm 1
This indicates whether the monitor has entered Alert/Alarm 1. A monitor will
enter the Alert/Alarm 1 state when any proportional value provided by the
monitor exceeds its configured Alert/Alarm 1 setpoint.
Danger/Alarm 2
This indicates whether the monitor has entered Danger/Alarm 2. A monitor
will enter the Danger/Alarm 2 state when any proportional value provided by
the monitor exceeds its configured Danger/Alarm 2 setpoint.
Bypass
This indicates when the monitor has bypassed alarming for one or more
proportional values at a channel. When a channel bypass status is set, this
monitor bypass status will also be set.
Configuration Fault
This indicates if the monitor configuration is valid.
Special Alarm Inhibit
This indicates whether all the nonprimary Alert/Alarm 1 alarms in the
associated monitor channel are inhibited.
The Channel Special Alarm Inhibit function is active when:
- The Alarm Inhibit contact (INHB/RET) on the I/O Module is closed
(active).
- A Channel Special Alarm Inhibit software switch is enabled.
Channel Status
OK
This indicates that no fault has been detected by the associated monitor
channel.
There are three types of channel OK checking: Transducer Input Voltage,
Transducer Supply Voltage, and Keyphasor OK. Keyphasor OK only affects
channel pairs that have Keyphasor signals assigned to them. A channel OK
status will be deactivated if any of the three OK types goes not OK.
Alert/Alarm 1
This indicates whether the associated monitor channel has entered
Alert/Alarm 1. A channel will enter the Alert/Alarm 1 state when any
proportional value provided by the channel exceeds its configured Alert/Alarm
1 setpoint.
Danger/Alarm 2
This indicates whether the associated monitor channel has entered
Danger/Alarm 2. A channel will enter the Danger/Alarm 2 state when any
proportional value provided by the channel exceeds its configured
Danger/Alarm 2 setpoint.

Bypass
This indicates that the channel has bypassed alarming for one or more of its
proportional values. A channel bypass status may result from the following
conditions:
- A transducer is not OK, and the channel is configured for Timed OK
Channel Defeat.
- The Keyphasor associated with the channel has gone invalid causing all
proportional values related to the Keyphasor signal (for example 1X
Amplitude, 1X Phase, Not 1X, ...) to be defeated and their associated
alarms bypassed.
- The monitor has detected a serious internal fault.
- A software switch is bypassing any channel alarming function.
- The Special Alarm Inhibit is active and causing enabled alarms not to be
processed.
Special Alarm Inhibit
This indicates whether all the nonprimary Alert/Alarm 1 alarms in the
associated monitor channel are inhibited.
The Channel Special Alarm Inhibit function is active when:
- The Alarm Inhibit contact (INHB/RET) on the I/O Module is closed
(active).
- A Channel Special Alarm Inhibit software switch is enabled.
Off
This indicates whether the channel has been turned off. The monitor
channels may be turned off (inactivated) using the Rack Configuration
Software.
