Bently Nevada 3500/34 3500 gas monitor

Description

You can configure the 3500/34 Hazardous Gas Detection Module in a Triple
Modular Redundant (TMR) module set for 2 out of 3 voting. A TMR
configuration requires 3 6-channel Hazardous Gas Detection Modules with
separate sensor inputs for each channel of the TMR channel group. TMR
configurations must also meet the following requirements:
• Each channel of the TMR channel group must reside on a separate
3500/63 Module.
• The modules within the TMR group must be in physically adjacent slots
within the 3500/34 Rack.
• TMR configurations must use the 3500/34 TMR Relay Module

Configuration Mode
This switch allows you to configure the monitor. To configure the
monitor, select this box and set the key switch on the front of the Rack
Interface Module or TDI in the PROGRAM position. When the Rack
Configuration Software downloads a configuration it will automatically
enable and disable this control. If the connection to the rack is lost
during the configuration process, uncheck this box to remove the
module from Configuration Mode.
Monitor Alarm Bypass
When you select the box for this switch, the monitor does not perform
alarming functions. The monitor still provides all monitored values.
The Gateway Communication Module and Display Interface Module
use the monitor switch number.

Although the concentration of calibration gas is below the lower explosive
limit, be sure to observe all safety precautions that relate to handling
combustible gas. In particular, we strongly recommend the following:
1. Refer to the Material Safety Data Sheet (MSDS) that accompanies the
gas canister for any required personal protective equipment (PPE).
2. Remove all ignition sources from the vicinity of the sensor prior to
performing the calibration procedure.
Bently Nevada, LLC advocates strict adherence to all applicable safety
regulations. Before attempting to perform any operations with
combustible gases, review all local and national safety requirements.
Based upon the location and requirements of your installation, personnel
who handle combustible gases may require additional training.

Channels of an unconfigured monitor cannot be calibrated. Before calibration an
initial configuration must be downloaded to the monitor. Refer to Section 6.
Use the following steps to calibrate a channel:
1. Power the sensor for at least 20 minutes prior to attempting the
calibration. This will permit the catalytic beads to warm up and stabilize
prior to calibration.
2. The channel must be in an OK state prior to calibration. If a channel is in a
NotOK state determine the cause and correct the issue. Refer to Section 10
for troubleshooting help. In some cases the NotOK condition may not be
removable by following troubleshooting measures. For example, if you
connected a sensor to a channel that had already been calibrated with
another older sensor the new sensor may be out of range in the negative
direction causing it to go NotOK because the channel is still using the old
sensor calibration data. In a case like this you may need to put the channel
into soft bypass prior to beginning calibration by using the software
switches (Refer to Section 6.4).
Application Advisory
Note that if you use the software switch to put the
channel into bypass the analog output will go to the
NotOK configured clamp value. Normally, during
calibration the analog output goes to 1.5mA.
3. If the channel is in an Alarm state or an Over Range state you must
remove that condition before calibration. If necessary:
a) Remove the alarm condition.
b) Acknowledge any removed alarm, if it was latching.
4. Isolate the catalytic bead gas sensor to be calibrated from all gas sources.
5. Purge the sensor by allowing fresh air to reach the sensor head until the
monitor detects no residual gas levels. Do not use commercially available
