indicator.
8. Attach the extended cover and tighten at least one-third turn past o-ring contact.
Note
The indicator may be installed in 90-degree increments for easy viewing. Mounting screws
may need to be installed in the alternative holes based on LCD orientation. One of the four
connectors on the back of the indicator assembly must be positioned to fit into the ten-pin
connector on the electronic board stack.
Note the following LCD temperature limits:
3.8 Transient protection
The optional transient terminal block prevents damage to the flowmeter from transients
induced by lightning, welding, heavy electrical equipment, or switch gears. The transient
protection electronics are located in the terminal block.
The transient terminal block meets the following specifications:
IEEE C62.41 - 2002 Category B.
3 kA crest (8 X 20
s)
6 kV crest (1.2 X 50
s)
6 kV/0.5 kA (0.5 s, 100 kHz, ring wave)
Note
The ground screw inside the terminal housing must be tightened for the proper operation
of the transient protection. Also, a high-current ground connection to earth is required.
3.8.1 Installing the Transient Protector
For flowmeters ordered with the transient protector option (T1), the protector is shipped
installed. When purchased separately from the Rosemount 8600D, you must install the
protector on a Rosemount 8600D flowmeter using a small instrument screwdriver, a pliers,
and the transient protection kit.
The transient protection kit includes the following:
One transient protection terminal block assembly
Three captive screws
Use the following steps to install the transient protector:
Operating: –4 to 185 °F (–20 to 85 °C)
Storage: –50 to 185 °F (–46 to 85 °C)
