Safety Precautions
TELAms products are designed in full consideration of safety. However,
improper handling during operation or installation is dangerous and may
lead to fire, electric shock or other accidents, resulting in serious injury or
death. In addition, these actions may also worsen machine performance.
Therefore be sure to read this Manual before operating, installing,
maintaining, inspecting, repairing or otherwise working on this unit.
Warning, Caution
• Do not use this unit with voltages other than specified supply
voltage as this may result in fire or electric shock.
• Do not disassemble or modify the unit as this may result in injury or
damage the internal circuits.
• Be sure to check the machine and device conditions to ensure safety
work on a machine.
• Be sure to switch off the power supply, air and other sources of
drive power before working on the machine.
• When turning on a machine power supply, take care about moving
parts of a machine and corresponding devices.
General precautions
When using TELAms products, observe the following general precautions along
with those given specifically in this manual to ensure proper use of the products.
• Provide adequate safety measures to prevent damages in case the product
should develop malfunctions.
• Use outside indicated specifications or purposes and modification of our
products will void any warranty of functions and performances
• When using our products in combination with other equipment, the functions
and performances as noted in this manual may not be attained, depending on
operating and environmental conditions.

Installation precautions
When installing this unit, care should be given to the following points to
prevent noise and electromagnetic wave interference from other equipment.
1. Do not pass lead and connection cables through the same ducts as
power lines.
2. Be sure to install the unit at least 0.5 m or more away from high voltage
or large current sources or high-power relays.
Installation place precautions
1. Mount the scale as closely as possible to the work-piece or to the object
being measured. Further the scale is mounted, greater is measuring error.
2. The scale unit should be used within an ambient temperature range of 0
to 50°C. Avoid locations where the scale is exposed to direct sunlight and
heat sources such as motors.
3. Do not place anything on the mounted scale, or step on it: excessive
force to the scale causes trouble.
Before installation
Do not disassemble parts other than scanning unit holder. All electrical
adjustments have also been completed before shipment. So do not tamper any
additional adjustment at time of its installation.
This scale unit consists of precision mechanism parts and electromagnetic
parts. Therefore, applying excessive pressure to the unit can seriously harm
the performance and service life of the scale. Be careful not to apply
excessive pressure to the scale unit when proceeding with the work.
When the unit is to be carried, support the scale unit and reading head
altogether. Do not hold the unit by the head cable, connectors, etc.
Ensure that the scale unit housing and reading head as well as the circuit
breaker for the supply power are properly grounded.
Standard procedure for EMC compliance.
When equipment such as controller does not function properly due to the effects
of large noise from power line please provide ground lines at one point
intensively. Power source which has a remote sensing function, must be used for
TGM133. Power unit without remote sensing unit may fail to prove optimum
functions. Please provide proper power source by referring to Section 5.

1. Outline
1-1. Before Operation
TGM133/134 series is small, light and high-accuracy optical feedback scale.
This series provides Line driver (A, A-, B, B-, RI, RI- digital output) or
Sinusoidal signals (1Vpp or 11µA output).
Output signals are adjusted before shipment, ex.-factory, each signal can be
readily used for connection to control device as it is.
