Safety Summary
SPECIFIC
WARNINGS
Consider the corrosive properties of the measured substance when
selecting piping materials. Degradation of the piping can upset the
process. Some process upsets can injure personnel and damage
equipment. (p. 3-5)
When pressurizing, avoid overloading and pressure hammer. Refer
to the introduction section for the pressure limits of the cell. Exceed-
ing this pressure could result in damage to the cell and cause seri-
ous injury to personnel. (p. 3-5)
Explosionproof/dust-ignitionproof installations and intrinsically safe
installations in Class II or Class III hazardous locations require that
the assembly be kept tight while circuits are live unless the location
is known to be nonhazardous at the time. (p. 4-1, 7-1, 8-1)
The outputs of smart devices change to a fixed value during initial-
ization and detected failure conditions. These values must be
selected by the user to ensure safe operation. (p. 5-3)
System maintenance must be performed only by qualified personnel
and only after securing the equipment controlled by the circuit.
Altering or removing components from an active circuit may upset
the controlled process leading to personnel injury and equipment
damage. (p. 7-1)
Repairs must be performed only by qualified personnel and only
after securing the equipment controlled by the circuit. Altering or
removing components from an active circuit may upset the con-
trolled process leading to personnel injury and equipment damage.
(p. 8-1)
SPECIFIC
CAUTIONS
If the cell with characterization board assembly has been cleaned
for oxygen and chlorine service, do not compromise the integrity of
this cleaning during these procedures. Impurities will react with oxy-
gen and chlorine and damage the transmitter and the process.
(p. 7-3, 8-1)
Clean the diaphragms with a soft rag and appropriate solvent. The
use of metal brushes, blades, or other tools will damage the dia-
phragms. (p. 7-3)
