Connect the Module
The 1442 sensors can be connected to many different Allen-Bradley 1440 XM
Series or 1444 Dynamix® Series modules. Refer to the appropriate Module User
Manual for wiring requirements and instructions on how to wire the sensor to the
module.
Verify the Connections
Before turning on the power, verify the following connections:
· Be sure that there are no loose terminals, and that all wiring is properly
connected.
· Check that the power line for the power source is connected to
NEGATIVE PWR (-24V) on the measurement module or its terminal
base.
· Be sure that the driver and sensor are installed at locations where the
installation environmental conditions are satisfied.
· Be sure that there are no problems with the driver and sensor installation,
and they are not installed at the following types of locations:
– Locations with high temperatures and high humidity.
– Locations with dust.
– Location exposed to vibration.
– Locations where there are metal objects, other than the target, near the
sensor.
After checking all items, check the set gap voltage values.
Set Gap Voltage
Perform confirmation of set gap voltage to maintain the performance of this unit
when doing the following:
• Supplying power to the unit for the first time
• More than one year has passed from the last confirmation
• The performance of this unit has been reduced due to a problem of some
sort
Follow these steps to check the set gap voltage.
1. Turn on the power.
2. Allow the unit to warm up for 5 minutes to stabilize the output.
