BAPI-Slim™ Wireless Temperature Transmitter

28936_ins_WFC

Identication and Overview

The BAPI-Slim Wireless Temperature Transmitter is designed to monitor temperature inside refrigerator and freezer cases. The BAPI-Slim mounts on the outside of freezer units and can be mounted either inside or outside of refrigerator units. The unit is available with an internal sensor or an RJ11 jack external sensor.

The external sensor’s ribbon cable can easily t between the door seal or through hole with FEP cable without affecting appliance efciency. The temperature is then transmitted at 30-second intervals to the receiver with a remote probe measurement range of -40 to 185˚F (-40 to 85˚C).

Mounting

BAPI-Slim™ Wireless Temperature Transmitter

Installation and Operating Instructions

rev. 06/03/16

There are two ways to mount the wireless transmitter. One uses a keyhole screw mount and the other uses double stick mounting tape. Both techniques

BATTERY TAB

can be used together if desired.

TRANSMITTER MOUNTING WITH TAPE

1. Remove the battery tab by pulling the tab straight out to start the transmitter (Fig. 4). The battery will last about 4 years before replacement is required.

2. Peel off one side of the mounting tape and apply the mounting tape to the back (Fig. 5).

Fig. 4: Transmitter

Activation & Battery

3. Select a location you would like monitored or within reach of the remote sensor. Any orientation is acceptable although vertical will enhance the transmitter distance.

4. Peel off the mounting tape, position the sensor and rmly push it into place.

5. For units with an internal sensor the mounting process is complete.

6. For remote sensors, string the wire through the freezer door and place the sensor in the best location to measure the required temperature.

7. Mount the External Probe using a Flexible Probe Bracket (Fig. 6) or use the clip or screw hole on the

a Flexible Probe Bracket (BA/FPB)

Hanging Bracket Sensor (Fig. 7)

TRANSMITTER MOUNTING WITH SCREWS

1. Remove the battery tab to start the transmitter (Fig. 4). The battery will last about 4 years before replacement is required.

2. Remove the back plate by inserting a small thin screwdriver in the bottom slot and pushing gently. Then swing the cover up and off (Fig. 8).

3. Select a location within reach of the remote sensor. Any orientation is acceptable although vertical mount will enhance the transmitter distance.

4. Mark the mounting holes by using the transmitter backplate as a template (Fig. 9). Drill holes and use hardware appropriate for the application (hardware not included).

6. For units with an internal sensor, the mounting process is complete. Place the transmitter over the back plate by hooking at the top of the back plate and swinging down until it snaps into place (Fig. 10).

7. For remote sensors, string the wire through the freezer door and place the sensor in the best location to measure the required temperature. Sensor removal from the transmitter may be necessary. See Fig. 11.

8. Mount the External Probe using a Flexible Probe Bracket (Fig. 6) or use the clip or screw hole on the Hanging Bracket Sensor (Fig. 7). Reconnect the remote sensor if necessary (Fig. 11)

9. Place the transmitter over the back plate by hooking the transmitter at the top of the back plate and swinging down until it snaps into place. Be sure the remote sensor wire is lined up with the bottom slot (Fig. 10).

Installation and Operating Instructions

28936_ins_WFC

Remote Sensor Connection

If the transmitter has an internal sensor then there is no external wiring. If a remote sensor is used, then it is terminated using an RJ11 connector inside the transmitter case.

Remote Sensor Connection

1. Remove the back plate by inserting a small thin screwdriver in the bottom slot and pushing gently. Then swing the cover up and off (Fig. 8).

2. An RJ11 connector is located at the bottom of the board. Insert the sensor RJ11 plug (tab down) into the connector until it is fully seated (Fig. 11).

3. Place the transmitter over the base plate by hooking the transmitter at the top of the back plate and swing down. Be sure the remote sensor wire is lined up in the bottom slot and swing the cover down until it snaps into place (Fig. 10).

Battery Replacement

New transmitter installations are powered by a pre-installed battery. To activate the unit, nd the battery tab insulator in the back of the unit, pull it out and discard the tab (Fig. 4) and push the training button (Fig. 14). The transmitter will start to transmit approximately every 30 seconds.

Battery Replacement

1. Replacement requires the removal of the back plate by inserting a small thin screw driver in the bottom slot and gently push then swing the cover up and off (Fig. 8).

2. Remove the old battery and install a new battery (BA/BAT-5AAHIT) so that the negative faces up toward the antenna (Fig. 12). Push the training button (Fig. 14) and the transmitter will start to transmit approximately every 30 seconds. The transmission LED (Fig. 13) will ash once for each transmission.

3. Place the transmitter over the base plate by hooking the transmitter at the top of the back plate and swing down. Be sure the remote sensor wire, if used, is lined up in the bottom through

slot and swing the cover down until it snaps into place (Fig. 10).

Setup and Commissioning

As soon as the batteries are installed (or the insulating battery tab is removed) and the training button is pressed, the transmitter will start to transmit the temperature using the serial # code shown on the battery holder (Fig. 12). A small transmit LED on the circuit board ashes once for each transmission. This happens at 30 second intervals. This LED is visible through the lower hole on the front cover (Fig. 13).

When using a receiver with one or more Analog Output Modules, the transmitter will have to be trained to an individual Analog Output Module on the receiver. To do this, push and hold the Service Button on the Analog Output Module you wish to train. Then push and release the Training Button on the transmitter with a paper clip through the top faceplate hole (Fig. 14). The Analog Output Module LED will light up, indicating a successful training process. The LED on the Analog Output Module will then ash with each received transmission, approximately every 30 seconds.

Diagnostics

Possible Problems: Possible Solutions:

The unit is suspected of not transmitting - Verify that the Transmit LED (Fig. 13) on the transmitter ashes at 30

second intervals. If the LED is not ashing, press the Training Button (Fig. 14) and recheck if the transmit LED is ashing.

Unit is not talking to the analog output module - If this is a 900MHz system (has a repeater), then be sure the repeater is

within range of the transmitter and within range of the receiver.

- Re-train the analog output module as described in the “Setup and Commissioning” section.

Sensor reads low - Remove the sensor from the case by unplugging the RJ11 plug.

Measure the resistance of the two center terminals and compare this resistance to the resistance found on the resistance/temperature chart for the 10K-2 thermistor on the BAPI website. If the measured resistance is different from the temperature table by more than 5%, call BAPI technical support. Find BAPI’s website at www.bapihvac. com; click on “Resource Library” and “Sensor Specs”, then click on the 10K-2 Thermistor sensor.

rev. 06/03/16

Battery may be low - Check the battery voltage to see that it is 2.6 volts or greater. If it is less

than 2.6 volts, replace the battery. The batteries should last for 4 years.
