SmartPower™ solutions

■ Optimized Emerson instrumentation, both hardware and software, to extend power module life

■ Intrinsically safe power module allows field replacements without removing the transmitter from the process, keeping personnel

safe, and reducing maintenance costs.

IEC 62591 (WirelessHART®)... the industry standard

Self-organizing, adaptive mesh routing

■ No wireless expertise required, network automatically finds the best communication paths.

■ The self-organizing, self-healing network manages multiple communication paths for any given device. If an obstruction is

introduced into the network, data will continue to flow because the device already has other established paths. The network will
then lay in more communication paths as needed for that device.

Safety shower and eye wash monitoring

The Rosemount 702 Transmitter can be used to monitor safety showers and eye wash stations by using switch kits provided by
TopWorx™, an Emerson company. These kits are ordered as a part of the Rosemount 702 model code and are available for both
insulated and un-insulated pipes. These kits contain the switches, brackets and cables that are necessary to install the transmitter to
monitor both the safety shower and the eye wash in a single station. Because each has two input channels, one transmitter can be
used to monitor both a safety shower and an eye wash.

Each safety shower monitoring kit contains:

■ Two TopWorx GO™ Switch magnetic proximity switches

■ Two cables, six-foot and 12-foot

■ Two black polymer cable glands

■ Mounting kit for safety shower and eye wash

UL and CSA switches

Safety shower and eye wash monitoring kits are available with either UL or CSA switches. This designation refers to the ordinary
location certification of the GO Switch in the kit. These are not hazardous locations certificates. The Go Switch is regarded as a
simple apparatus and does not require its own hazardous locations certificate. Either GO Switch is suitable for installation in
hazardous locations when wired to the Rosemount 702 with an appropriate hazardous locations certificate. The CSA GO Switch is
for applications in Canada, the UL GO Switch is for applications in all other world areas.

Installation drawings and instructions

Installation drawings and instructions for safety shower and eye wash kits are included in the Rosemount 702 Transmitter

Reference Manual. This manual can be downloaded at the Rosemount 702 Transmitter Product Page.

Safety shower monitoring

When the shower valve is activated (valve open) by pulling down on the handle, the TopWorx switch is activated (closed switch) and
the Rosemount 702 senses that switch closure. This switch state is then transmitted by the transmitter to the Gateway, which then
sends that information to the control host or alert system. When the shower valve is closed, the switch remains in the activated
state until it is reset by a technician. The switch can be re-set only by placing a ferrous metal object on the far side of the sensing
area of the switch.

Eye wash monitoring

When the eye wash valve is activated (valve open) by pushing down on the hand paddle, the TopWorx switch is activated (closed
switch) and the Rosemount 702 senses that switch closure. This switch state is then transmitted by the transmitter to the Gateway,
which then sends that information to the control host or alert system. When the eye wash valve is closed, the switch remains in the
activated state until it is reset by a technician. The switch can be re-set only by placing a ferrous metal object on the far side of the
sensing area of the switch.
