RKI INSTRUMENT AirLink 5950 Wireless Switch State Transmitter Instruction Manual

RKI INSTRUMENT AirLink 5950 Wireless Switch State Transmitter

Overview

The AirLink 5950 is a WireFree Switch-State Transmitter for use in conjunction with a new or existing WireFree system. The AirLink 5950 receives signals from up to two individually addressable sensors (pressure switch, temperature sensor, flow sensor, tank level sensor,etc.), and then transmits the state of (and change of state of) that switch. This document should be read before initial operation of the product.

NOTE : The figures and enclosure wording in this manual represent the AirLink 5950 XP; however, the AirLink 5950 NXP’s internal components and operation are identical.

Sensor Wiring Setup

NOTE: The figures and enclosure wording in this manual represent the AirLink 5950 XP; however, the AirLink 5950 NXP’s internal components and operation are identical.

Although applications will vary, most switches use three wires: normally open (NO), common (COMM) and normally closed (NC). On the opposite side of the board from the terminals, there are two switches that determine whether the NO or NC side of the connected switch is being monitored by the control board. If the side being monitored is open, a “0” will appear on the screen and be transmitted. If the side being monitored is closed, a “1” will appear on the screen and be transmitted.
Wiring to Sensor 1
The AirLink 5950 is a wired transmitter that uses an external 4 – 20 mA sensor provided by the user. Refer to the following procedure when wiring the Sensor 1 to the transmitter.

1. Power off the device by touching and holding the magnetic wand against the right side of the device for four seconds to activate SUB.

2. Unscrew and remove the enclosure lid.

3. Grip the front panel thumbscrews and pull the front panel out of the enclosure.
   CAUTION : Do not use any metal object to help remove the front panel. Do not remove any connecting wires.

4. Locate the Sensor 1 terminal block on the control board and rotate the board so that the terminal block is accessible for wiring.
   CAUTION: Use appropriate construction techniques to maintain the explosion- proof classification of the assembly.

5. Connect a wire (red) from Sensor 1 to the terminal labelled “NO” on the Sensor 1 Terminal Block.

6. Connect a wire (black) from Sensor 1 to the terminal labelled “COMM” on the Sensor 1 Terminal block.

7. Connect a wire (green) from Sensor 1 to the terminal labelled “NC” on the Sensor 1 Terminal Block.

8. To wire in Sensor 2, proceed to the next section. To finish wiring Sensor 1, replace the unit back in the enclosure by matching each mounting post to its corresponding eyelet inside the enclosure.

9. Verify that each mounting post is properly fitted in its corresponding eyelet inside the enclosure.

10. Verify that the sealing ring (located on the threads of the open enclosure) is still in place.

11. Place the enclosure lid on top of the enclosure base.

12. Rotate the lid until it is tightly screwed in place (approximately 20 rotations).

Wiring to Sensor 2
The AirLink 5950 is a wired transmitter that uses an external 4 – 20 mA sensor provided by the user. Refer to the following procedure when wiring Sensor 2 to the transmitter.

Maintenance

NOTE : The figures and enclosure wording in this manual represent the AirLink 5950 XP; however, the AirLink 5950 NXP’s internal components and operation are identical

Battery Replacement
To ensure full-functionality, the battery should be replaced if the voltage is less than 3.0. To check the battery voltage, refer to the Viewing the Unit Info section this manual. The device uses a “D” Lithium 19AH battery with connector. New batteries should only be obtained from RKI Instruments, Inc.

WARNING: Only use RKI-supplied replacement batteries. Do not mix old and new batteries. Do NOT charge battery packs.
CAUTION: The internal components can be static sensitive. Use caution when opening the enclosure and handling internal components. DO NOT use any metal objects or tools to remove the batteries.

1. Press and hold the SUB button for approximately 4 seconds, until “OFF” shows on the display screen.

2. Unscrew the enclosure lid and set it aside.

3. Pull straight up on the Front Panel Thumb-Screws until the internal components are removed from the standing eyelets.
   CAUTION: Do not use any metal object to help remove the front panel. Do not remove any connecting wires.

4. Locate the battery connectors on the terminal board assembly. Squeeze the locking tab on one battery plug and gently pull it straight out of the battery connector. Repeat this step for the second battery plug and connector.

5. Gently remove the batteries from the battery spring clips.

6. Gently slide the new batteries into the spring clips in the same orientation as the old batteries.

7. Plug the battery on the bottom of the radio board into the closer battery terminal.

8. Plug the battery on the top of the radio board into the other available battery terminal.

9. Place the internal system back into the enclosure, matching each mounting post to its corresponding eyelet anchored within the base of the enclosure.

10. Using the thumbscrews, gently push to seat the internal system into the mounting posts.

11. Verify that the sealing ring, seated at the threaded opening of the device enclosure, is correctly in place.

12. Secure the enclosure lid back onto the enclosure.
    WARNING : When securing the lid onto the device, tighten the enclosure lid by hand ONLY. Overtightening of the lid by use of hand-tools could result in damage to the O-ring, potentially compromising the moisture seal, resulting in an unsafe environment

13. Press the ADD button to initiate the 1-minute startup. Power on the device and check the battery voltage to ensure that the new battery is fully functional and at 3.6 volts. For instructions on how to check the battery voltage, refer to the Using the Advanced enu Mode section this manual.

Antenna Replacement

The antenna is used to aid in sending clear and reliable radio signals to the transmission controller. If necessary, the current antenna can be replaced by an RKI Instruments, Inc.-approved 2.4 GHz or 900 MHz antenna. To replace the antenna, perform the following:

1. Power off the device by pressing and holding SUB for 4 seconds
2. Unscrew the antenna’s connector from its fitting.
3. Screw the replacement antenna onto the fitting.
4. Power on the device by pressing ADD

Troubleshooting

The troubleshooting guide describes symptoms, probable causes, and recommended action for problems you may encounter with the AirLink 5950.
NOTE: This troubleshooting guide describes AirLink 5950 problems only. See the controller operator’s manual for problems you may encounter with the controller.

AirLink 5950 Fault Codes

Problem| Cause(s)| Solution(s)
F1| The control board has lost commu- nication with the 4-20mA device.| 1. Check the connection between the 4- 20 mA device and the AirLink 5950.
F14| The AirLink 5950 cannot identify a primary controller.| 1.      Ensure the AirLink 5950’s Radio Address matches the sensor assembly’s address is correct and unique.

2.      Ensure the AirLink 5950’s Network ID matches the primary controller’s Network ID.

*    System faults will activate the fault terminal.
