Section 2 Installation
d. Microprocessor Transmitter with Alarm and Pulse Output Wiring
Connections.
Since this is a magnetically activated device, strong magnetic
fields and materials with magnetic properties may cause faulty
operation when in close proximity to the flowmeter. This includes
steel pipes, steel conduit, motors, and transformers.
CAUTION
Flowmeters with a transmitter must be mounted at least 18 inches
apart to prevent the interaction of adjacent float magnets and
transmitter.
CAUTION
To prevent ignition of hazardous atmospheres and serious
personal injury, proper installation methods must be used as
defined in Article 505 of the National Electrical Code and the
Canadian Electrical Code and ISA Stnadard 12.6.
WARNING
Figure 2-6 Typical SMM Transmitter with Alarms and Pulse Digital Output and Power Wiring
7. Under actual flow conditions, verify that the transmitter output matches
the mechanical pointer position. If a discrepancy is noted, the HART
communications channel can be used to verify or adjust the transmitter
settings. The Emerson Model 275 hand held communicator provides a
simple means to accomplish this check anywhere in the loop. Refer to
Figure 3-2 for connection instructions.
Note: The Brooks SMM transmitter device description (DD) will not be
programmed into the Emerson Model 275 hand-held communicators
until after Summer 1997. Until the Brooks device description becomes
standard to the Emerson Model 275 units, please contact Brooks
Customer Service, Hatfield, PA, to provide programming for a nominal
fee. After Summer 1997, we request that the customers update their
Model 275 units through Emerson Service Centers located throughout
the world.
