modified 10/03/97
the iq 1000 ii is a self-contained, door mounted, motor protection device which may be applied to 50hz or 60hz 3-phase motor starters or switchgear, including low-, medium-, and high-voltage equipment.
the iq-1000 ii monitors 3-phase ac motor currents to develop an accurate thermal model of motor heating. a separate rtd module option allows the iq 1000 ii to combine the monitored motor stator temperature with the motor current information. the resulting combination of data allows the iq 1000 ii to develop a more detailed picture of the motors temperature, thereby maximizing motor utilization.
the iq 1000 ii operates by monitoring motor current, and takes the motor off-line when it detects a problem such as an overcurrent or overtemperature condition. if an operating parameter exceeds its setpoint value, the iq 1000 ii initiates a trip condition.
catalog number: iq1000ii

when connecting an iq 1000 ii to the universal rtd module using the fiber optic
link, a separate fiber optic cable is required. the fiber optic cable may be no longer than 400 feet in length.
this cable is available from hewlett packard. for details on this fiber optic cable, reference the following link
