Conventions used in
this manual
All dimensions and specifications are shown in the format
mm [inches] unless specified otherwise.
Language
These are the original instructions, written in English.
Theory of operation
The H3275 LED Light Source is used as a backlight for an
optical sensor or camera in a web or strip guiding system. The
H3257 provides uniform LED light output through a diffusing
lens, which is captured by a sensor or camera to provide
information about the material position. The device can be
configured to emit 7.5 kHz light (pulsed) or DC light.
Factory-calibrated LED intensity levels can be easily selected
by actuating a pushbutton switch. An internal dry-contact
relay indicates the status of the light source.

Using the H3109
Discriminating
Detector
There are special considerations when the H3257 is used as a
light source for the H3109 sensor.
1. Always set the H3257 to intensity 8 (default).
2. Always set the H3257 to operate in pulsed mode (default).
3. A 4.7kΩ (1/4 W) load resistor must be placed across the
H3109 output and COM.
On most controllers, the resistor can be placed across the
detector input (such as DET 1 or DET2) and the COM
terminals at the controller. See Figure 3 .

Operation
LED intensity settings
The H3257 functions as a stand-alone light source using
factory calibrated light intensity/profile settings.
Factory calibration sets the drive level of each LED to the
same value for each of eight profile settings. See Table 3.

OPERATION
www.maxcessintl.com
Fife H3257
MI 1-921 1
Adjusting the light
intensity
The H3257 must be powered on to change the intensity. The
device will retain the selected intensity level between power
cycles.
Adjustment button
Adjust the intensity level with a small pushbutton located
behind a hole plug on the front panel.
-Gently pry out the hole plug.
-Use a small, non-conductive tool to actuate the button.
-Each press of the button increases the intensity level by
10% of the maximum.
-Once the maximum intensity has been reached, the
intensity will revert to Setting 1 on the next button press.
LED bar graph
Next to the pushbutton is an 8-LED green bar graph.
Each lit LED in the bar graph represents one intensity level.
This H3257 is set at intensity level 4.
Dual light source only
This H3257 is operating as the slave.
In dual configuration, both light sources use the same
intensity, which is controlled and displayed on the master
light source.

OPERATION
www.maxcessintl.com
Fife H3257
MI 1-921 1
Enabling DC light mode
By default, the light emitted from the H3257 is pulsed at
7.5 kHz. When the H3257 is used as a light source for line scan
or array cameras, use DC light mode.
To configure the H3257 for DC light mode, the DC Mode Plug
must be installed on the 4-pin SYNC connector before turning
on the power. See page 3-3 .
One DC mode plug is required for each H3257 LED Light
Source.
Enabling dual H3257
synchronization
The available lengths of the H3257 are sufficient to support
most applications. If necessary, two light sources may be used
to achieve the required length.
Dual light sources must be synchronized when used with a
single sensor. This occurs automatically when a synchroniza-
tion cable is installed between the 4-pin SYNC connector of
each H3257 prior to turning on the power. See page 3-3 .
Table 4 summarizes the behavior of the H3257 based on the
configuration of the SYNC connector.

Table 4. Summary of H3257 light modes based on SYNC connector
Synchronization is not required if each H3257 is to operate in
DC light mode.
A power cycle must occur for synchronization or a light mode
change to occur.

H3257 faults and
status contact
The H3257 provides a contact closure in series with the 5-
pin power connectors to indicate an internal fault to other
devices in the system.
The contact is closed during normal error-free operation.
The contact will be open under any of the following
conditions:
-Loss of power
-Internal microcontroller error
-Internal power supplies out of tolerance
-LED fault (entire 11" section of LEDs are open/short
circuit)

MAINTENANCE
www.maxcessintl.com
Fife H3257
MI 1-921 1
Maintenance
In some environments, dust and dirt will build up on the lens
of the H3257, reducing its effective light output.
Daily
Wipe the lens of the H3257 with a clean, damp, soft cloth.
Use ordinary soap and warm water.
Do not use abrasive materials or chemicals on the lens.
Damage may occur.
Do not soak or spray the detector with fluids.
Electrical damage may occur.
