Network Configuration - United Electric Controls VANGUARD Installation And Operation Instruction Manual

2.9 Network Configuration

A Network ID and Join Key are required to communicate
over the wireless network.
It is recommended that network configuration be
performed right after battery installation to maximize
battery life. The device must be configured to communicate
over the wireless network. A Network ID and Join Key are
required, and must match the Network ID and Join Key
of the wireless gateway and other wireless devices in the
network.
This device sends critical gas concentration information
reliably and securely via WirelessHART communication
protocol. Configuration can be completed using any
HART handheld communicator, or directly into the
control system using a HART modem. HART terminals
are located inside the intrinsically safe battery
compartment and are clearly marked (see Figure 31).
Configuring the gas detection device in the hazardous
area requires a suitable, approved intrinsically safe
device (such as a handheld communicator, etc.). The
entity parameters of the device being connected must
be compatible with those of the gas detection device.
Before connecting any device in the hazardous location,
the following entity parameters must be verified:
U ≤ U prog
o i
I ≤ I prog
o i
P ≤ P prog
o i
C ≥ C prog
o i
Gas Detector Intrinsic Safety Entity Parameters:
U = 4.935V; I = 0.179A; P

Connected Device Entity Parameters (will vary
dependent upon device):
U prog = Max. voltage that can be connected at the input to the
i
handheld or other programming device
I prog = Max. current that can be connected at the input to the
i
handheld or other programming device
P prog = Max. power that can be connected at the input to the
i
handheld or other programming device
L prog = Max. inductance that can be connected at the input to the
i
handheld or other programming device
C prog = Max. capacitance that can be connected at the input to the
i
handheld or other programming device
U prog = Max. voltage that the handheld or other programming
o
device can source to the device being programmed
L ≥ L prog

I prog = Max. current that the handheld or other programming
o
device can source to the device being programmed
