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:
ASME B16.5 (ANSI)/IEEE C62.41 - 1980 (IEEE 587) Categories A, B.
3 kA crest (8  20
m s).
6 kV crest (1.2  50
m s).
6 kV/0.5 kA (0.5
m 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.
Installing the
Transient Protector
For flowmeters ordered with the transient protector option (T1), the
protector is shipped installed. When purchased separately from the
Model 8800C, you must install the protector on a Model 8800C
flowmeter using a small instrument screwdriver, a pliers, and
the transient protection kit (part number 8800-5106-1002 or
8800-5106-1004).
The transient protection kit includes the following:
• One transient protection terminal block assembly
• Three captive screws
• One ground screw
