Red Lion PCU - Manual (Page 10)

A programmable User Input is available with RS485, Valve Position, and
Second Analog Input models. The User Input can be programmed to perform
a variety of controller functions.
An optional NEMA 4X/IP65 rated bezel is available for wash down
applications and similar environments, when properly installed. Modern
surface-mount technology, in-house assembly and testing, and high
immunity to noise interference makes the controller extremely reliable in
industrial environments.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in
the manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Do not use the PCU to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit. An independent and redundant
temperature limit indicator with alarm outputs is strongly recommended. Red
Lion Controls offers various units (such as an IMP, IMD1, or IMD2) that may
be used for this purpose. The indicators should have input sensors and AC
power feeds independent from other equipment.
