iBox Field Connections
The majority of field connections to the iBox are made through pluggable terminal strips along
the left edge of the iBox (as you face it). Field connections are control and data connections to
and from equipment external to the iBox. For example, connections through the traveler cable
to car and hoistway equipment or connections to additional machine room equipment like rope
grippers, velocity encoders, governors, etc. In this section, three tables describe connections —
iBox connections, expansion board connections, and iControl terminal connections respec-
tively.
Tach Error Lower Limit
This signal represents the lower margin of tach error allowed at
contract speed before a tach fault is generated. Display with
Speed Feedback signal to see the margin. If Speed Feedback
crosses Tach Error Lower Limit the tach fault will be generated.
Please refer to “Tach Error Tripping Threshold Adjustment” on
page 2-50
.

ment” on page 4-40

Tach Error Upper Limit
This signal represents the upper margin of tach error allowed at
contract speed before a tach fault is generated. Display with
Speed Feedback signal to see the margin. If Speed Feedback
crosses Tach Error Upper Limit the tach fault will be generated.
