User Manual: Field Transmitter 1 General 1.1 Device Overview The power and communication unit (PCU) is an intrinsically safe, IEEE 802.15.4 2.4GHz device. The PCU can be paired with additional sensors which are capable of detecting the presence of hydrocarbons in the air, water and ground. Two field-interchangeable sensors provide detection of hydrocarbons, temperature, inclination, acceleration and liquid height.
User Manual: Field Transmitter WARNING: Substitution of components not expressly specified by Syscor will void intrinsic safety certification. 1.2.2 Federal Communications Commission (FCC) Part 15 This device complies with FCC Rules Part 15 operation and is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference, including interference that may cause undesired operation of the device.
User Manual: Field Transmitter b. Impedance 50 Ω Installation 2.1 Location Planning PCU location will depend on availability of mounting locations and presence of possible interference for wireless network transmission. Sensor location will be dictated largely by the needs of the system being monitored. A variety of options are available for mounting both the sensor and PCU together or separately as needed. Range of permitted environmental conditions: • • • • 2.1.
User Manual: Field Transmitter Both the PCU and the sensors use standard ½” NPT threads for assembly. For locations where more durability is required, sensors may be mounted using standard ½” NPT threaded pipe and associated fittings to protect the sensor cable. Figure 3: PCU with rigid pipe-mounted sensor The PCU may be mounted anywhere a convenient mounting surface is available.
User Manual: Field Transmitter The PCU mounts to the Generic Mounting Bracket using Qty. 4 #10-32 screws and star washers as shown. Figure 6: Sample generic mounting bracket configuration 2.3 Magnetic Surface Mounting Bracket The Magnetic Surface Mounting Bracket is intended for applications where the inclinometer on the PCU is used, but not exclusive to this application. The base assembly of the bracket is dropped into place on a nominally level magnetic surface.
User Manual: Field Transmitter 2.4 Wiring Sensors to the Power and Communication Unit Up to two sensor probes may be connected to the PCU. Sensor probes may be screwed directly into the PCU ports or mounted remotely. For systems with zero sensor probes, ensure both PCU cable glands have a plug installed. Plugs are shipped with every PCU but can be purchased from the manufacturer separately if misplaced or lost. Please read the warnings regarding field replacement at the end of section 2.4.
User Manual: Field Transmitter Figure 14: Sensor probe wiring (see 2.4.1 and 2.4.2 setup instructions) Figure 13: PCU wiring compartment 2.4.1 Directly Mounting a Sensor Probe to the PCU A directly mounted sensor probe is one that is screwed directly into the PCU body. For all other types see section 2.4.2: Attaching a Remotely Mounted Sensor Probe to the PCU.
User Manual: Field Transmitter 1) Apply two wraps of ¾” wide PTFE tape around the gland threads in the clockwise direction according to Figure 10: Direct mounted PTFE tape application Remove the port plug if one is installed and screw the gland into one of the two ½” NPT ports on the bottom of the PCU. Ensure the gland is tightly screwed to the PCU expecting that the gland does not screw in all the way due to the PTFE tape.
User Manual: Field Transmitter 2.5.1 Battery Installation/Replacement Procedure 1. Unscrew the outer cover from the side closest to the mounting bosses. 2. If replacing a battery, remove Qty. 3 M4x6mm Button Head screws from standoffs on battery holding board using a 2.5 mm hex key tool. Disconnect the battery harness from the connector and remove the battery pack. Skip this step and proceed to step 3 if a battery is not present in the device. 3.
User Manual: Field Transmitter 2.7 Network Configuration Network configuration must be performed after battery installation in order to maximize battery life. Devices that have not been configured will spend energy searching for a network to join. A Network Identity (ID) and Join Key are required to join a WirelessHARTTM network and they must match the Network ID and Join key of the WirelessHARTTM Gateway. Network configuration can be completed using any HART handheld communicator.
User Manual: Field Transmitter Operation 3.1 Normal Operation Under normal operation, three variables are transmitted at variable update rate using burst message 0. The update rate is programmable from 1 second up to 3600 seconds. Burst messages can be configured using the device descriptor and a Field Communicator.
