Curremt Transducer Connectors
The connectors route the incoming signals from the Magnet Station
Connectors to external level and/or temperature instruments. If an AMI
Liquid Helium Level Instrument is purchased with the Model 430
Programmer and magnet system, an LHe level cable will be provided.
Warning
Although the LHe level sensor connector terminals are isolated from
earth ground and therefore touching one terminal is not hazardous,
the voltage between terminals is at a hazardous potential if an AMI
Liquid Helium Level Instrument is connected and energized. The
LHe level sensor pins are designed for use with an AMI LHe sensor
and the wiring for the sensor is to have no live parts which are
accessible. Conductors connected to its terminals must be insulated
from user contact by basic insulation rated for 150 VAC
(Category I).
Note
For maximum noise immunity, use shielded cabling and connect
one end of the shield to the LHe Level / Temp Connector shell.
A.3 Current Transducer Signal Connector
The current transducer signal connector provides pins for connection of the
current transducer (CT) signal to the Model 430; power to the CT is also
provided via this connector. The connector is a 9-pin
D-sub female connector with the shell lugs connected to the Model 430
Programmer chassis ground.
