BA-WFP-BLE-PT Wireless Food Probe

Overview and Identification

• NSF certified with food and dishwasher safe materials
• User adjustable settings via receiver or WAM
• Onboard memory to store readings when communication is interrupted
• Transmits to a digital Gateway or a wireless-to-analog Receiver

BAPI’s Wireless Food Probe measures the temperature and transmits the data via Bluetooth Low Energy to a receiver or gateway. The food probes eliminate the need for an employee to hand record the temperatures  with a thermometer for HACCP compliance. Bin clips are available to fit most food bins. The probe is designed for dishwasher or hand washing.Because the probes are designed for wet, dusty or dirty environments, there are many additional applications including cooling towers, steam humidifiers or dusty/wet conveyor systems.

Adjustable Settings

BAPI’s wireless devices have several settings that can be can be field adjusted to suit the needs of the installation. All settings are configured by either BAPI’s cloud based Wireless Asset Monitoring (WAM) or the  receiver. (See the WAM or receiver instructions available on the BAPI website for more information on adjusting the settings.)
Sample Rate/Interval – The time between when the sensor wakes up and takes a reading. The available values are 10 sec, 30 sec, 1 min, 3 min or 5 min with the gateway, or 30 sec, 1 min, 3 min or 5 min with the  receiver.
Transmit Rate/Interval – The time between when the sensor transmits the readings to the gateway or receiver.
The available values are 30 sec, 1, 2, 3, 4, 5, 10, 15, 20 or 30 minutes, or 1, 6 or 12 hours with the gateway, or 1, 5, 10 or 30 minutes with the receiver.
Delta Temperature – The change in temperature between sample intervals that will cause the sensor to override the transmit interval and immediately transmit the changed temperature. The available values are 0.1,  0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5 °F or °C with the gateway, and 1 or 3 °F or °C with the receiver.
Temperature Min/Max – The maximum or minimum temperature that will cause the sensor to override the transmit interval and immediately transmit a reading to the gateway. (Only available when using a  gateway.)
Temperature Offset – Adjusts the temperature value being transmitted to match that of a calibrated reference device. The available values are ±0.1, 0.2, 0.5, 1, 2, 3, 4 or 5 °F or °C. (Only available when using a gateway.)

Associated Receiver or Gateway

RECEIVER (Wireless-to-Analog)
The wireless receiver from BAPI receives the data from one or more wireless sensors. The data is then transferred to the analog output modules and converted to an analog voltage or resistance. The receiver supports  up to 32 sensors and up to 127 different analog output modules.

GATEWAY
The wireless gateway receives the data from one or more wireless sensors. The gateway then provides the data to the cloud via MQTT. The gateway also sends a confirmation signal to each sensor upon a successful  reception of data. The gateway supports up to 32 sensors.
Please see BAPI’s Wireless Quick Start Guide, or the gateway or receiver instructions available on the BAPI website (www.bapihvac.com/gateway-quick- start) to establish communication between the sensors and the  gateway or receiver.

Initial Activation

For convenience, BAPI recommends pairing the sensor to the intended receiver or gateway prior to mounting either device. Both devices need to be powered-on to pair. See the receiver or gateway installation manual for instructions on pairing the sensor.

1. Cover Removal:
   Unscrew the clear cover from the black probe bottom with the included food probe wrench (Fig 1). Do not use the stainless steel probe for leverage.

2. Battery Tab Insulator Removal: The food probe is powered by a pre-installed battery. To activate the unit, find the battery tab insulator, pull it out and discard the tab (Fig. 2). Press the “Service” button  and the “Service LED” on the back side of the circuit board (Fig. 6) should flash once to confirm power.

3. Cover Installation: Hand-tighten the cover onto the black probe bottom until the cover is snug to the bottom (Fig 4).

Note: The cover and base are matched by serial number and MAC address.

Operation

Power the unit as described in “Initial Activation” section. Follow the gateway or receiver instructions for pairing the unit and changing the adjustable settings. (The instructions are available on the BAPI website.)

Wireless Sensor Reset

Sensors remain paired to the gateway or receiver and output modules when power is interrupted or the batteries are removed. To break the bonds between them, the sensors need to be reset. To do this, press and  hold the “Service Button” on the sensor for about 30 seconds. During those 30 seconds, the green LED will be off for about 5 seconds, then flash slowly, then begin flashing rapidly. When the rapid flashing stops, the  reset is complete. The sensor can now be paired to a new receiver or gateway. To re-pair to the same receiver or gateway, you must reset the receiver or gateway. Output modules that were previously paired to the sensor do not need to be re-paired.

Onboard Memory

Sensor retains up to 16,000 readings should the communication become interrupted. The sensor only stores readings from missed transmissions and only when the sensor is paired to a gateway. Once  communication is re- established with the gateway, the stored readings are transmitted and then erased from the sensor. The current reading and nine previous readings are sent at each transmit interval until the  sensor is caught up. Temporarily shortening the transmit interval will allow the sensor to more quickly clear any stored readings.

Battery Replacement and O-Ring Inspection

Check or replace batteries and O-ring at yearly intervals.

1. Battery Inspection and Removal: Remove the cover as described in the “Initial Activation” section on pg 2. Inspect the battery to be sure it is not corroded. If it is corroded or suspected of being bad, remove the  battery from its holder and discard in an environmentally safe manner.
2. Battery Installation: Place the new battery in the holder in the correct orientation (Fig. 7).
3. O-Ring Inspection: Inspect the rubber O-Ring for kinks, scarring, or cracking. Replace as necessary and lubricate with any food safe lubricant. Re-install the cover as described in the “Initial Activation” section on pg. 2.
   Battery Specifications: One 3.6V lithium battery (#14250 or equiv.)

Probe Cleaning

The Wireless Food probes can be hand washed or washed in a commercial or residential dishwasher.
PRECAUTIONS:

1. Normal long-term use and washing will result in micro scratches which may cloud the plastic shell, but will not affect performance.
2. To ensure the water seal, confirm that the cover is screwed on securely (hand tight) before each washing cycle.
3. To avoid probe failure, DO NOT twist the stainless steel probe.
4. Metal brushes or copper/steel wool should never be used on the food probe.
5. Use of sanitizers at higher than 150ºF will harm the plastic case and could cause water infiltration and damage the sensor. Washing the probe in a sanitizer over 150ºF will void the warranty.

HAND WASHING:

1. Follow standard food industry hand washing procedures.
2. Use a wash cloth, sponge or nylon brush to clean the metal and plastic surfaces.
3. Rinse the probe and towel dry or place in storage rack to dry.

DISHWASHER:

1. Standard dishwasher detergents and rinse agents will not harm the metal probe or plastic.
2. Typical dishwasher cycle times of less than 5 minutes at less than 165ºF (74ºC) are acceptable.
3. Typical rinse cycles of less than 5 min. at less than 212ºF (100ºC) are acceptable. However, a rinse with sanitizer should not exceed 150ºF (65ºC).
4. Place the food probe into the washer rack or flatware rack loosely so that all sides of the probe will be exposed to washing fluid. The probe can be in any orientation. (up/down/or on its side)

Diagnostics

Possible Problems:
Sensor is not communicating with the gateway or receiver, or the transmitted values are incorrect.
Possible Solutions:
Make sure the sensor is within range of the gateway or receiver.
Verify that the green LED on the sensor circuit board flashes when the “Service” button is pressed, indicating a transmission. If it does not flash, replace the battery.
Verify that the sensor is properly paired to the  gateway or receiver and analog output modules as described in the gateway or receiver instructions available on the BAPI website. Re-pair them if needed. If necessary, perform the “Wireless Sensor Reset” procedure on page 2.
