Instrumentation Requirements

Miscellaneous: Additional instrumentation devices required are a current transformer mounted around one

phase of the drive motor leads to measure main motor amperage, and two rotary potentiometers to read the

position of the slides. The amperage signal provides annunciation for high motor amperage, and is used in the

capacity control logic. The rotary potentiometers indicate the position of the slides, which is used as a start-

ing permissive and in the capacity control logic. Also, additional input points may be required for customer

connection of remote signals such as Start and Stop commands, and capacity setpoint control.
