7.
NEVER - Remove a transmitter from an instrumentation loop with the power on. Protection circuitry designed to absorb small power surges
could become shorted and cause transmitter failure due to “arcing”.
8.
NEVER - Ground a transmitter to AC Return (White). Instant “fatal” failure occurs.
9.
NEVER - Apply input power to the case ground (Green wire). Reduced life span of protection components will occur.
MAINTENANCE AND REPAIR
All Viatran transmitters have been designed to function free from routine or scheduled maintenance. Simple cleaning of the electrical
connection and pressure cavity on an as needed basis will provide many years of satisfactory performance. Protecting the product from
continued exposure to moisture or fluids at the electrical connection, breather area (model dependent) will eliminate premature internal failure
of the product. Generally any time the product is removed from service the connector and pressure port threads should be cleaned and the
pressure cavity flushed with a 316SS and/or O-Ring (material model dependent) compatible cleaner to prevent media buildup. During the
cleaning process only a soft, lint-free cloth is recommended. Never use a coarse or stiff bristle brush to clean media from the diaphragm surface.
It is suggested that the calibration be verified on a usage dependent schedule. If the product is in continuous service 7 days a week, then
calibration verification may be necessary every 6 to 8 months. If the product is in a lab test environment a more lenient verification schedule
would be appropriate. In all instances the performance of the product will depend on the individual application or process in which it is installed.
More continued usage would require a shorter period between calibration verification and product maintenance.
If a product is perceived to be exhibiting problems, it can be returned to Viatran for analysis and/or repair. It is suggested that only Viatran
personnel attempt repair of the product. Any damage resulting from customer disassembly would result in a loss of coverage under the warranty
policy. All Viatran products are able to be repaired at minimal cost if simple cleaning and precautions are taken in the handling and application
of the product. Older products returned for repair are updated to current specifications unless the repair cost would outweigh the cost of a new
replacement model. Products returned for repair should include information on the person to contact for repair quote approval, the individual to
contact if Viatran’s technical staff requires additional information during analysis, and a brief description of the problem associated with the
product’s failure
.
