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.
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.
1.3 Disposal Statement
Customer and third parties that are in control of product at the end of its life or at the end of its use are solely responsible for proper disposal of product. No person, firm, corporation, association or agency that is in control of product shall dispose of it in a manner that is in violation of United States state laws, United States
federal laws, or any applicable international law. Bently Nevada is not responsible for disposal of product at the end of its life or at the end of its use.

3500/60-/61 Operation and Maintenance General Information
2. General Information
The 3500/60-/61 Temperature Monitor is a six-channel monitor designed for temperature measurement applications. It accepts input from either resistance temperature detectors (RTD) or thermocouples (TC) and uses these inputs to drive
alarms. The monitor can be programmed using the 3500 Rack Configuration Software.

General Information 3500/60-/61 Operation and Maintenance
The primary purposes of the 3500/60 and /61 monitors are to provide 1)
machinery protection by continuously comparing current machine temperature against configured alarm setpoints to drive alarms and relays, and 2) essential machine temperature information to both operator and maintenance personnel. Alarm setpoints are configured using the 3500 Rack Configuration Software. Alarm and danger setpoints can be configured for the active proportional value.
The 3500/60 and /61 ship from the factory unconfigured. A spare monitor can be re-configured for different applications as needed. To configure a monitor install the monitor in a 3500 rack and follow the instructions in section 3 Configuration Information.
2.1 Triple Modular Redundant (TMR) Description
When used in a TMR configuration, 3500/60-61 Monitors and corresponding 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 modules are compared in a 2 out of 3 method. Two modules 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.
The second type of voting is referred to as \voting, the proportional value outputs of each module in the group are compared with each other. If the output of one module differs from the output of the other modules in the group by a specified amount, that module will add an entry to the System Event list. Configure comparison voting by setting Comparison and % Comparison in the Rack Configuration Software.
For TMR applications, the Temperature monitor requires three redundant
transducers at each measurement location on the machine. The input from each transducer is connected to separate 3500 Temperature monitors
2.2 Available Data
The Temperature Monitor returns process data proportional values to the Communications Gateway Module, Display Interface Module, and to the host software via the Rack Interface Module. The Temperature Monitor also returns both module and channel statuses.
2.2.1 Statuses
The monitor provides the following statuses. This section describes the available statuses and where they can be found.

3500/60-/61 Operation and Maintenance 2.2.1.1 Module Status
OK
General Information
This indicates if the module 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 Channel not OK
If the Module 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 module has entered Alert/Alarm 1. A module will enter the
Alert/Alarm 1 state when the process proportional value provided by the module exceeds its configured Alert/Alarm 1 setpoint.
Danger/Alarm 2
This indicates whether the module has entered Danger/Alarm 2. A module will enter the Danger/Alarm 2 state when the process proportional value provided by the module exceeds its configured Danger/Alarm 2 setpoint.
Bypass
This indicates when the module has bypassed alarming the proportional value of a channel. When a channel bypass status is set, this module bypass status will also be set.
Configuration Fault
This indicates if the monitor configuration is valid.
2.2.1.2 Channel Status
This indicates whether or not the associated module channel has detected a fault. A not OK status is returned under any of the following conditions:
? ?
Transducer Failure
Channel Specific Hardware Failure
OK
Alert/Alarm 1
This indicates whether the associated module 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 module 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:
? ?
