1.1 Emerson 404B Infrared Phototach description of intended
use
The 404B Infrared Phototach is a self-contained, reflective sensor. The 404B
Infrared Phototach is relatively immune to ambient light sources, making it
ideal for outdoor use in areas where reflected light and glare cause
conventional phototachs to malfunction. It provides direct readings up to
20,000 RPM at distances up to three feet. Distances may vary with RPM. The
phototach's small effective beam makes it a good choice for sensing
relatively small objects, while its visible red light makes it extremely easy to
align.
The 404B Infrared Phototach is intended to be used with an AMS 2140
Machinery Health Analyzer, with or without an optional 408 battery pack.
The 404B Infrared Phototach can be powered directly from an AMS 2140
Machinery Health Analyzer with the cable provided in the package. The
optional 408 battery pack may also be used with the 404B Infrared Phototach
for extended use.
The 404B Infrared Phototach can only be connected directly to the AMS 2140
Machinery Health Analyzer via the required tach cable purchased from
Emerson. See the AMS 2140 Machinery Health Analyzer User Manual for
more information.
The 404B Infrared Phototach is an accessory to the AMS 2140 Machinery
Health Analyzer. This document includes the basic instructions for setting up
the 404B Infrared Phototach and connecting it to the AMS 2140 Machinery
Health Analyzer.

1.2 Overview
This document describes the basic connections and set up for the 404B
Infrared Phototach. Refer to the AMS 2140 Machinery Health Analyzer User
Guide for detailed instructions for data collection.
1.3 Clean the product
To clean the exterior of the phototach or battery pack, use only a dry, lint-
free towel or cloth dampened with a mild soap and water solution. Do not
use any abrasive or corrosive chemicals or materials, or any petroleum
distillates and ketone solvents (for example, acetone, gasoline and
kerosene).

2 Charge the 408 battery pack
Topics covered in this chapter:
•Test the 408 battery pack
•Charge the 408 battery pack
2.1 Test the 408 battery pack
Before charging, test the battery pack to see if it has already been charged.
Procedure
1. Locate the power switch on the 408 battery pack.
408 battery pack front panelFigure 2-1:
A. Power switch
2. The power switch has three positions: On (left), Off (middle), and Battery
Test (right). Press the power switch to the right to test the battery. A
successful battery test is indicated by a red light. If the light shows red,
then the battery pack has a charge. If the light does not show red, the
battery needs to be charged.

Note
The current model of the 408 battery pack uses six NiMH batteries. Older
models of the 408 battery pack use NiCad batteries. If the battery pack
cannot properly be charged, these batteries may need to be replaced.
Batteries must be replaced by Emerson. See the Return of Materials
section in this manual for more information.
2.2 Charge the 408 battery pack
The 404B Infrared Phototach can be powered directly from an AMS 2140
Machinery Health Analyzer using the cable provided in the package.
However, for extended use the 404B Infrared Phototach can be powered
from the 408 battery pack.
CAUTION!
The 408 battery pack should be charged before first use.
Note
A wiring diagram is provided on the back of the 408 battery pack for quick
reference.

Procedure
1. Find the appropriate power cable for your use in your country.
2. Connect the smaller end of the power charger cable to the connector
labeled CHARGER on the 408 battery pack.
Note
The power charger may not insert completely into the 408 battery pack.

3 Connect the 404B Infrared Phototach
Topics covered in this chapter:
•Connect the 404B Infrared Phototach to the AMS 2140 using the 408 battery
pack
•Connect the 404B Infrared Phototach to the AMS 2140 without using the
408 battery pack
3.1 Connect the 404B Infrared Phototach to the AMS 2140
using the 408 battery pack
You can use the 408 battery pack to power the 404B Infrared Phototach
while connected to the AMS 2140 Machinery Health Analyzer.
Procedure
1. If the 408 battery pack has been charged, you may remove the power
cable. It is not needed since the 408 battery pack will be running off of
battery power.
2. Connect the 404B Infrared Phototach cable to the INPUT connector on
the 408 battery pack by turning it clockwise until tightened.

3. The appropriate cable for use with the AMS 2140 has a BNC connector on
one end and an eight pin Turck connector on the other end. Connect the
Turck connector to the VOLTS/TACH connector on the AMS 2140
Machinery Health Analyzer.

4. Connect the BNC connector on the other end of the cable to the OUTPUT
connector on the 408 battery pack. Turn the BNC connector clockwise
until you feel it click into place. At that point the cable is connected.
5. Turn the power switch on the 408 battery pack to the ON position by
pushing the power switch to the left.
6. The infrared light on the 404B Infrared Phototach is illuminated.

3.2 Connect the 404B Infrared Phototach to the AMS 2140
without using the 408 battery pack
The 404B Infrared Phototach can be powered directly from the AMS 2140
Machinery Health Analyzer for shorter periods of use. In order to power the
404B Infrared Phototach directly from the AMS 2140 Machinery Health
Analyzer, the red power switch on the front of the AMS 2140 Machinery
Health Analyzer must be set to the ON position. Also, the Tach Power setting
must be turned on in the AMS 2140 Machinery Health Analyzer Tachometer
Setup screen. See the AMS 2140 Machinery Health Analyzer User Guide for
more information.
Follow these steps to connect the 404B Infrared Phototach to the AMS 2140
Machinery Health Analyzer without using the 408 battery pack.
Procedure
1. Connect one end of the tach cable to the VOLTS/TACH connector on the
AMS 2140 Machinery Health Analyzer.

4 Set up the 404B Infrared Phototach
Topics covered in this chapter:
•Adjust the magnetic mount
•Position the 404B Infrared Phototach to detect a pulse
4.1 Adjust the magnetic mount
A magnetic mount is provided with the 404B Infrared Phototach. The mount
can be adjusted to pivot in a wide range of angles and can be tightened to the
desired angle using the knob on the mount, as shown below.

4.2 Position the 404B Infrared Phototach to detect a pulse
Use the reflective tape provided as your fixed reference to be able to start
collecting data from rotating equipment. Proper operation of the 404B
Infrared Phototach requires it to be mounted securely and properly aligned.
There is a red light on the back of the 404B Infrared Phototach that indicates
Quick Start Guide June 2018
16 MHM-97921, Rev 0

if a pulse has been detected. Excessive movement or vibration can cause an
intermittent or false operation due to a loss of alignment to the targeted
area.
Note
If you are attaching the magnetic mount to equipment that is not grounded,
there is a possibility of producing a ground loop (electrical) problem that will
cause the 404B Infrared Phototach to become unstable.
1. Place the reflective tape provided with the package on the shaft of the
equipment to be analyzed. If the surface of the shaft is shiny or of a
reflective nature, the 404B Infrared Phototach will capture false readings.
Paint the shaft on the area surrounding the attached tape with a darker,
non-reflective color.
2. Position the 404B Infrared Phototach perpendicular to the reflective tape.
404B Infrared Phototach properly positioned for useFigure 4-2:
If a pulse is not detected, change the angle of the 404B Infrared Phototach to
10 to 15 degrees off a line perpendicular to the reflective tape.
If the 404B Infrared Phototach signals are erratic, you may need to adjust the
gain on the 404B Infrared Phototach:
1. Remove the screw holding the clear plastic cover on the rear of the yellow
tach head.
2. Ensure that the L.O.\D.O. control is in the full counterclockwise position.
June 2018 Quick Start Guide
MHM-97921, Rev 0 17

3. The gain control is a multi-turn "clutched" control. Turn it clockwise until
there is a clicking sound indicating that the control is all the way in. Then,
turn the control counterclockwise two full turns.
4. Replace the clear plastic cover.
If you still have erratic signals after making these adjustments, back out the
gain control another full turn or more until you obtain a satisfactory signal.
Note
Refer to the Balancing chapter of the AMS 2140 Machinery Health Analyzer
User Manual for more operating instructions for the 404B Infrared Phototach.
