13.3.1.1 Specific Conditions of Safe Use
1. When EPL Ga or Da is required, parts of the equipment containing
light metals (Aluminum or Titanium) shall be protected from
impact so that impact or friction sparks cannot occur, taking into
account rare malfunction. Measures to prevent impact or friction
sparks when using the equipment containing light metals include
but are not limited to
• Mounting the probe vertically
• No mechanical agitation shall be used
• Use of stilling wells to mitigate effect of agitation.
• Limit rate of change of level to values such that friction sparks
cannot occur
2. The maximum permitted ambient temperature of the Level Plus
Digital/Analog Level Transmitter is 71 °C. To avoid the effects of
process temperature and other thermal effects care shall be taken
to ensure the surrounding ambient and the ambient inside the
transmitter housing does not exceed 71°C
3. Warning: The equipment contains non-metallic enclosure and
process parts. To prevent the risk of electrostatic sparking, the
non-metallic surface should only be cleaned with a damp cloth.
Painted surface of the equipment may store electrostatic charge
and become a source of ignition in applications with a low relative
humidity <~30% relative humidity where the painted surface is
relatively free of surface contamination such as dirt, dust or oil.
Cleaning of the painted surface should only be done with a damp
cloth.
4. The applicable temperature class, process temperature range and
ambient temperature range of the equipment is as follows;
• T3 with Process Temperature Range of -40°C to 150°C
• T4 with Process Temperature Range of -40°C to 135°C
• T5 with Process Temperature Range of -40°C to 100°C
• T6 with Process Temperature Range of -40°C to 85°C
• Ambient Temperature Range -40°C < Ta < 71°C
