minimum continuous voltage is available to the Optira encoder under all operating conditions.
3.2 Installation Considerations
The Optira encoder is a precision electronic instrument. It has been designed to function in a wide
range of applications and environments. To take full advantage of the Optira design, allow easy
access to the sensor for service and/or replacement.
For optimal performance and reliability:
•DO follow standard ESD precautions while handling the sensor.
•DO allow proper clearance for sensor head alignment.
•DO follow setup and calibration instructions for the encoder system.
•DO, where possible, install the scales in an inverted or vertical position to minimize
accumulation of dust.
•DO NOT store sensors in an uncontrolled environment.
•DO NOT electrically overstress the sensor (power supply ripple/noise).
•DO NOT intentionally “hot swap” the sensor if the device is energized.
•DO NOT use in high contamination applications (dust, oil, excessive humidity, or other
airborne contaminants).

6.1.4.1 Status LED Version A (Standard)
Alignment is positioning of the sensor with respect to the scale to achieve proper signal strength
from the count track and the index track. Proper sensor alignment may require minor adjustments
to the sensor position with respect to the scale.
Sensor alignment can be performed easily by using the sensor’s Status LED indicator, which
lights depending on sensor alignment as follows:
Note1: The Status LED can be ordered with all four colors available, or with only red available for
alarm indication (see Section 7.0 Order Guide).
LED
Color
1
System Status
Green
Optimal alignment:
Optimal position signal with minimum power consumption
Encoder system meets specification.
Greenish
Yellow
Good alignment:
Optimal position signal at specified power consumption
Encoder system meets specification.
Orange
Alignment could be improved but fully operational:
Sensor is reading position with marginal signal strength.
Encoder system functions but vector magnitude may not be 1
Vpp and SDE may exceed specification.
Red
Sensor fault:
Sensor is reading position with weak signal strength, or
Power supply is less than 4.2 V, or
Power supply is greater than 5.5 V, or
Sensor moving faster than 5.8 m/s.

LED Indications for Index Detection
•LED flashes bright when passing over index
•LED stays bright if stopped on index
Align Sensor
Perform the following steps to align the sensor:
6.1.4.2 Status LED Version B
Version B can be specified when there is a requirement for low ambient light. Version B operates
identically to Version A on each power-up state facilitating sensor alignment. After 5 minutes,
however, the LED operates as a fault indicator only.
If calibration is initiated after the 5 minute period the LED will blink as in Version A but will revert
to alarm indication only after calibration is complete.
6.1.5 LSB Index Calibration
Calibration is the process where the Least Significant Bit (LSB) index is set to its most stable
operating location, which is centered within the sensor’s 20 µm wide, raw Index Window (IW).
Calibration is only required for sensors with the LSB Index option (see Section 7.0 Order
Guide). Analog sensors or digital Optira sensors configured with the 20 µm Index Window do not
require calibration.
When to perform calibration:
•When installing the sensor for first time
•If the sensor is subsequently remounted
•If the scale is replaced
Step
Action
1.
Apply power to sensor.
2.
Ensure that the sensor’s mounting screws are loosely tightened. Slowly move the sensor by
allowing it to slide on the mounting surface until the Status LED illuminates green.
3.
Confirm that the green LED flashes brightly when passing over the index. If not, readjust the
sensor in the Y direction and repeat the above procedure.
4.
When alignment is completed, tighten the sensor mounting screws per the torque
specification: 0.34Nm (3 inch-lbs.) maximum.
5.
Confirm that the LED remains green over the full range of motion.
6.
If the sensor is not aligned over the entire range of motion:
•Loosen the sensor mounting screws and repeat this procedure starting at Step 1.
•Confirm that the scale has been installed parallel to the motion axis and that the LED
remains green through the full range of motion.
Result: The LED remains green throughout travel and flashes over the Index.

Notes3:
1. Optira implements Overspeed Buffer Protection (OBP). No AqB counts are lost for velocities below 4830 mm/s even if the
maximum specified rate is exceeded. If the velocity exceeds the specified state rate, the AqB counts are buffered (buffer
length = 21 m at 4000x interpolation depth) and transmitted at the specified state rate.
2. The ALARM bit sets TRUE at 4 m/s, however, Optira will continue to produce valid AqB outputs up to
6 m/s although accuracy specifications are no longer guaranteed.
Maximum Velocity (Analog)
Sine/Cosine Vector Magnitude: > 0.5 Vpp at 4 m/s

7.2 Power-Up Timing
The Optira encoder will be ready 420 ms after the 3.3 V or 5 V supply rises, during which the LED
will flash red and the Alarm signal will transition true. The encoder will be ready once the Alarm
transitions false per the following chart (5 V model is shown; chart also applicable for 3.3 V
model):

Digital/Analog Outputs Alarm Circuit Example
Alarm output is an open collector
circuit that is factory programmable:
either active high or active low;
specify when ordering. Alarm requires
an external pull-up resistor. See
customer-supplied circuit example on
right.
Note: Maximum cable length is 5 m. Contact MicroE Applications Engineering if longer lengths are
required.
