BAPI BA-RCV-BLE-EZ Wireless Receiver and Analog Output Modules Instruction Manual

Overview and Identification

The Wireless Receiver from BAPI receives the signal from one or more wireless sensors and supplies the data to Analog Output Modules through an RS485 four- wire bus. The modules convert the signal to an analog voltage or resistance for the controller. The receiver can accommodate up to 32 sensors and 127 different modules.
The Resistance Output Module (ROM) converts the temperature data from the receiver into a 10K-2, 10K-3, 10K-3(11K) or 20K thermistor curve.

The Voltage Output Module (VOM) converts the temperature or humidity data from the receiver into a linear 0 to 5 or 0 to 10 VDC signal. There are eight factory set temperature ranges (°F and °C) and humidity ranges of 0 to 100% or 35 to 70%RH. See the product label for the range and output.

The Setpoint Output Module (SOM) converts the setpoint data from a wireless room sensor into a resistance or a voltage. There are five factory set voltage and resistive ranges, each with an optional override function.

Pairing of the Sensor, Receiver and Analog Output Modules

The installation process requires that each wireless sensor is paired to its associated receiver and then to its associated output module or modules. The pairing process is easiest on a test bench with the sensor, receiver and output modules within arm’s reach of each other. Be sure to place a unique identification mark on the sensor and its associated output module or modules after they have been paired to each other so that they can be identified at the job site.
If more than one variable is transmitted by the sensor (temperature, humidity and setpoint for instance), each variable requires a separate output module. Multiple output modules can be paired to the same variable if desired.

PAIRING A SENSOR TO THE RECEIVER
You must pair the sensor to the receiver before pairing the sensor to an analog output module.

1. Select the sensor that you wish to pair to the receiver. Apply power to the sensor. See its manual for detailed instructions.
2. Apply power to the receiver. The blue LED on the receiver will light and remain lit.
3. Press and hold the “Service Button” on the top of the receiver until the blue LED starts to flash, then press and release the “Service Button” on the sensor (Figs 3 & 4) that you want to pair to the receiver. When the LED on the receiver returns to a solid “On” and the green “Service LED” on the sensor circuit board blinks rapidly three times, the pairing is complete. Repeat this process for all sensors.

PAIRING AN OUTPUT MODULE TO A SENSOR
Once the sensor is paired to the receiver, you can pair output modules to the sensor’s variable.

1. Select the output module for the desired sensor variable and range and connect it to the wireless receiver (Fig 1).
2. Press and hold the “Service Button” on the top of the output module until the blue LED begins to flash (about 3 seconds). Then, send a “pairing transmission signal” to that output module by pressing and releasing the “Service Button” on the wireless sensor.

The blue LED on the receiver will flash once indicating that a transmission was received; then the blue LED on the output module will go solid for about 2 seconds and then turn off. The sensor and output module are now paired to each other and will remain paired to one another through battery replacement or if power is removed from wire power
units. The output module’s blue LED will now flash once whenever it receives a transmission from the sensor.

Note: The wireless sensors are often measuring and transmitting multiple varibles, such as temperature and humidity,
or temperature, humidity and setpoint. All of these variables are transmitted when the sensor’s “Service Button” is pressed. However, each Analog Output Module is configured at the time of order to a specific variable and range so it will only pair to that variable and not the others.

Mounting and Locating of Antenna

The antenna has a magnetic base for mounting. Although the receiver may be located inside a metal enclosure, the antenna must be outside the enclosure. There must be a non-metallic line of sight from all the sensors to the antenna. Acceptable line of sight includes walls made from wood, sheet rock or plaster with non-metallic lath. The orientation of the antenna (horizontal or vertical) will also affect the performance and varies by application.
Mounting the antenna on a metal surface will cut off reception from behind the surface. Frosted windows may block reception too. A wooden or plastic furring strip attached to a ceiling beam makes a great mount. The antenna may be hung from any ceiling fixture using fiber or plastic twine. Do not use wire to hang, and do not use perforated metal strapping, commonly called plumbers tape.

Mounting of Receiver and Analog Output Modules

The receiver and output modules can be snaptrack, DIN Rail or surface mounted. Each receiver can accommodate up to 127 modules. Start with the receiver at the far left, then securely attach each output module to the right.

Push in the blue mounting tabs to mount in 2.75″ snaptrack. Push out the mounting tabs for DIN Rail. Catch the EZ mount hook on the edge of the DIN rail (Fig 7) and rotate into place. Push out the mounting tabs for surface mounting using the four supplied screws,
one in each tab.

If your output modules cannot fit in one straight line because of limited space, then mount a second string of modules above or below. Connect wires from the right side of the first string of modules to the left side of the second string of modules. This configuration requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN) for the extra wire terminations on the left and right side of the Analog Output Modules.
Each kit includes one set of 4 connectors.

Termination

The Wireless Receiver and Analog Output Modules are pluggable and can be connected in an attached string as shown at right. The power for the bus can be supplied to the receiver or to the last output module on the right side, but not to both places at the same time. Be sure you have enough power for all the devices on the bus.

Extending the RS485 Network between the Receiver and the Analog Output

Modules

The Analog Output Modules may be mounted up to 4,000 feet away from the receiver. The total length of all the shielded, twisted pair cables shown in Fig. 10 is 4,000 feet (1,220 meters). Connect the terminals together as shown in Fig. 10. If the distance from the receiver to the group of Analog Output Modules is greater than 100 feet (30 meters), provide a separate power supply or voltage converter (such as BAPI’s VC350A EZ) for that group of Analog Output Modules.

Note: The configuration in Fig 10 requires one or more Pluggable Terminal Block Kits for the extra wire terminations on the left and right side of the Analog Output Modules. Each kit includes one set of 4 connectors.

Receiver Switch Settings

All sensor settings are controlled and adjusted by the receiver to suit the needs of the installation. These are adjusted via the DIP switches on the top of the receiver. These are the settings for ALL OF THE SENSORS that are paired to that receiver.

Sample Rate/Interval ­ The time between when the sensor wakes up and takes a reading. The available values 30 sec, 1 min, 3 min or 5 min.

Transmit Rate/Interval ­ The time between when the sensor transmits the readings to the receiver. The available values are 1, 5, 10 or 30 minutes.

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 1 or 3 °F or °C.

Delta Humidity ­ The change in humidity between sample intervals that will cause the sensor to override the transmit interval and transmit the changed humidity at the next sample interval. The available values are 3 or 5 %RH.

Resetting a Sensor, Receiver or Analog Output Module

Sensors, receivers and output modules remain paired to each other when power is interrupted or the batteries are removed. To break the bonds between them, the units need to be reset as described below:
TO RESET A SENSOR: 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. To re-pair to the same receiver, you must reset the receiver. Output modules that were previously paired to the sensor do not need to be re-paired.
TO RESET AN OUTPUT MODULE: Press and hold the “Service Button” on the top of the unit for about 30 seconds. During those 30 seconds, the blue LED will be off for the first 3 seconds and then flash for the remaining time. When the flashing stops, release the “Service Button” and the reset is complete. The unit can now be re-paired to a sensor variable.
TO RESET A RECEIVER: Press and hold the “Service Button” on the sensor for about 20 seconds. During those 20 seconds, the blue LED will flash slowly, then begin flashing rapidly. When the rapid flashing stops and returns to solid blue, the reset is complete. The unit can now be re-paired to wireless sensors. Caution! Resetting the receiver will break the bonds between the receiver and all sensors. You will have to reset each sensor and then re-pair each of the sensors to the receiver.

Wireless System Diagnostics

Possible Problems:
The reading from the sensor is incorrect or at its low limit:

Possible Solutions:
– Check for proper wiring and connections from the output modules to the controller.
– Check to see if the controller’s software is configured properly.
– Press the sensor’s “Service” button (as described in the Analog Output Module Pairing section on pg 1) and verify that the green LED on the sensor circuit board flashes. If not, replace the batteries.
– Check for proper power to the receiver and Analog Output Modules.

The LED on the top of the Analog Output Module is blinking rapidly:

– Re-pair the Analog Output Module as described on pg 1, and verify that the blue LED on the output module flashes when a transmission is received.

The sensor reading is coming out – Re-pair the Analog Output Module as described on pg 1, and verify that the blue the wrong output module:

LED on the output module flashes when a transmission is received.

Default Status When Wireless Transmission is Interrupted

If an output module does not receive data from its assigned sensor for 35 minutes, the blue LED on the top of the module will blink rapidly. If this happens, the individual Analog Output Modules will react as follows:

• Resistance Output Modules (BA/ROM) will output the highest resistance in their output range.
• Voltage Output Modules (BA/VOM) calibrated for temperature will set their output to 0 volts.
• Voltage Output Modules (BA/VOM) calibrated for humidity will set their output to their highest voltage (5 or 10 volts).
• Setpoint Output Modules (BA/SOM) will hold their last value indefinitely.
  When a transmission is received, the output modules will revert to normal operation in 60 seconds or less.
