Step 1: Verify Sensor Configuration; Step 2: Insert Sensor Batteries And Turn On Battery Power - OneVue A120 Installation Manual

Tubing guidelines
• It's recommended to only use the supplied flexible silicone tubes.
• Tubing is free of crimps or obstructions that may inhibit airflow to the pressure ports.
• Tubing is clean and do not allow material to fall into the pressure ports, as contamination could damage the sensors.
• Arrange tubing to minimize stress on the connections to the pressure ports.
• Tubing can be cut to length to support application use.
• If the tubing used is longer than the supplied 6 ft. (1.82 m) tubing, reading accuracy may be affected due to reduced
air flow within the tubing. A general rule is that for each additional 2 ft. (.61 m) of tubing, a 1% of error is introduced
into the differential pressure reading. For applications that are only interested in a positive or negative pressure
indication, the overall accuracy of the reading may not be an issue. For application use requiring tubing lengths that
exceed 6 ft. (1.82 m), please contact your Primex support representative to calculate the extended tubing error rate.

Step 1: Verify sensor configuration

Prior to installation, a sensor device must be configured for use with OneVue. A sensor is either configured prior to
shipment through Device Preconfiguration or onsite using the OWDC app.
• Device Preconfiguration completed: white label with configured settings is affixed to the backside of the sensor.
Sensor has been configured with network settings allowing its connection to OneVue and also added to OneVue.
Proceed to next install step.
• OWDC onsite configuration required: Sensor shipped with factory default settings and is not added to OneVue.
You must configure the sensor now using the OWDC app.

Step 2: Insert sensor batteries and turn on battery power

1. Remove device cover; simultaneously press the two tabs located on the top side of the device (A).
2. Insert the 3.0v Primex Lithium/Iron Disulfide Battery Pack or two 1.5v Lithium AA batteries. Follow the symbols
showing the correct way to position the positive (+) and negative (-) ends of the battery pack.
3. Located to the lower-right of the battery compartment, set the battery on/off switch to the Up (On) position (B).
4. Replace the device cover.
