I/O and Control

The ASD can be controlled by several input types and combinations thereof, as well as operate within a
wide range of voltage levels. This section discusses the ASD control methods and supported I/O
functions.

Function (Default for programmable terminals)
Fire Speed
— Multifunctional programmable discrete input.
Customer Interlock — The CIA-to-CIB connection is accomplished via a jumper, a relay, or some other
user-selected means and is required for normal system operation.
Damper Response — The DRA-to-DRB connection is accomplished via limit switches at the fully-
opened damper and is required for normal system operation.
RR — Multifunction programmable analog input (0.0 to 10 volt input — 0 to 80 Hz output).
RX — Multifunctional programmable analog input (-10 to +10 VDC input — Unassigned).
II — Multifunctional programmable analog input (4 to 20 mADC input — Unassigned).
VI — Multifunctional programmable analog input (0 to 10 VDC input — Unassigned).
24 VDC @ 50 mA output.
PP — 10.0 VDC voltage source for the external potentiometer.
Damper Command — Multifunctional programmable output that is used to open/close the 120 VAC
damper motor power circuit when the motor is ASD-driven (see
acceleration or deceleration ramp is reached.
Frequency Pulse — Multifunctional programmable output that produces a pulse train that has a
frequency which is based on the output frequency of the ASD.
Output Current — Multifunctional programmable output that produces a DC current that is proportional
to the magnitude of the output current.
Output Frequency — Multifunctional programmable output that produces a DC current that is
proportional to the magnitude of the output frequency.
