BAPI Wireless Thermobuffer Temperature Sensor Instruction Manual

BAPI Wireless Thermobuffer Temperature Sensor

Product Information

• The Wireless Thermobuffer Temperature Sensor is a product designed by BAPI for use in freezers and coolers. It is capable of measuring temperature and transmitting the data via Bluetooth Low Energy (BLE) to either a digital gateway or a wireless-to-analog receiver. The sensor features a SS thermobuffer hanging bracket probe with an IP66-rated BAPI-Box enclosure and FEP-jacketed cable available in 5 or 10-foot length.
• BAPI’s wireless devices have adjustable settings that can be configured to suit the installation requirements. These settings can be adjusted using the gateway or receiver. The receiver supports up to 32 sensors and up to 127 different analog output modules, while the gateway supports up to 32 sensors.

   • Wire Power Units: Open the unit cover to access the circuit board or connect 24 VAC+ to the power terminals. Press the Service button and make sure the Service LED flashes once to confirm power.
2. Mounting: Mount the enclosure to the surface using BAPI recommended #8 screws. Use the enclosure tabs to mark the pilot hole locations. Mount the hanging bracket thermobuffer to a wire shelf or wall.
3. Operation: Power the unit as described in the Initial Activation section. Follow the gateway or receiver instructions for pairing the unit and adjusting the settings. The instructions can be found on the BAPI website.

Overview and Identification

•  User adjustable settings
•  Onboard memory
• Transmits to a digital Gateway or a wireless-to-analog Receiver
  BAPI’s Wireless Thermobuffer Sensor is designed for freezers and coolers. It measures the temperature and transmits the data via Bluetooth Low Energy to a receiver or gateway. It features a SS thermobuffer hanging bracket probe with an IP66-rated BAPI-Box enclosure and FEP-jacketed cable in 5 or 10 foot (1.5 to 3m) length.

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 the gateway or the receiver. (See the gateway or receiver instructions documents 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 transmit the changed temperature at the next sample interval. 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 minumum 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 from BAPI 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 documents available on the BAPI website to establish communication between the sensors and the gateway or receiver.

Initial Activation

• Battery Power Units
  The unit comes with two pre-installed batteries. To activate the unit, open the cover to access the batteries. Find the battery tab insulators and pull them out. Press the Service button and the Service LED should flash once to confirm power.

• Wire Power Units
  To activate the unit, open the cover to access the circuit board and apply the 9 to 30 VDC or 24 VAC to the power terminals as shown. Press the Service button and the Service LED should flash once to confirm power.

Mounting

Mount the enclosure to the surface using BAPI recommended #8 screws as shown in Fig 4. A 1/8” inch pilot screw hole makes mounting easier through the tabs. Use the enclosure tabs to mark the pilot hole locations. Mount the hanging bracket thermobuffer to a wire shelf or wall as shown in Fig 3.

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.

Battery Replacement

• Open the cover to access the batteries (Fig 7).
• Remove the batteries from their holders and discard in an environmentally safe manner. Replace with new batteries in the correct orientation.

Battery Specifications:
Two 3.6V Lithium batteries: (#14505, 14500 or equivalent)

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.

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 batteries.
• 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 as described on the pg 3.
