6.1.3 PCB Mounting
Perform the following steps to mount sensor to customer's PCB. Refer to sensor information in
Section 3.0 System Overview
.
Note
: A scale must be installed before installing the sensor. Refer to the
Optira Series
Encoders Tape and Glass Scales Installation Manual.
Step
Action
1. Use spacers to maintain sufficient space between sensor and PCB.
2. Press sensor to PCB carefully ensuring good connection for mating connectors.
3. Insert mounting screws between sensor and PCB through spacers.
4. Attach surface mount fasteners securely.
5. Install the PCB on the mounting surface referencing the appropriate datum surface as
shown in the Optira Interface Drawing. Use two M1.6 or 0-80 screws and tighten per torque
specification: 0.34Nm (3 inch-lbs.) maximum.
6. Connect PCB to customer’s electronics or to the optional Connector and Calibration Board.
6.1.4 Sensor Head Alignment
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:
Note
1
: 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.
Encoder system may not function properly.
Alarm signal will be asserted.
