PV Display First Digit: Hierarchy of the Parameter Second to Fifth Digit: Parameter Name SV Display: Parameter Data PV, SV & MV Bar Graph displays are active during Parameter Setting. Setup Parameters Access • 11 segment PV/Parameter display. • Hierarchy of parameter shown. • To access SETUP • menus, US1000 must be in MANUAL
Auto-tuning ends at 3rd peak. Being Auto-tuning SV PV PID control according to PID parameter obtained by auto-tuning. 100% 100% MV 0% Auto Tune Feature • Uses open loop response to calculate PID values. • Automatically varies the output (MV) from 0-100% to determine step response. • Auto tune is turned off after the third PV peak. • Super control (fuzzy logic) is available for control stability during PV disturbances or setpoint (SV) changes.
PC or PLC MODBUS or PC-Link Max: 1200m Up to 31 controllers Option /A10 for PC or PLC Communication • MODBUS RTU or ASCII (RS485 2 or 4 wire) • Up to 31 controllers per serial port. • Distance is limited to 1200 m (4000 ft). • Can be connected to Lantronix LDS-10 for network connectivity. (Modbus TCP)
Custom Computation • Available in US1000-11 & -21. • Requires LL1200-E10 Custom Computation Tool. • Select a US mode similar to the application requirements. • Select the appropriate computational modules. • Download the custom computation using the light loader or RS485 comm. port.
