The dual PCB assembly allows the K3P to easily fit inside compact equipment unsuitable for conventional panel controllers. The custom display provides a complete view of the process with an easy to use operator interface. A wide range of hardware combinations and special software functions make this customizable controller a highly flexible solution for a wide range of advanced control and profiling applications, such as furnace and atmosphere control, environmental and growth chambers. The programmer facility has storage capacity of 200 segments, in up to 90 programs. Each program may be linked for maximum pattern storage flexibility. Universal- thermocouple, RTD or process linear inputs coupled with a responsive, SMART auto-tuning PID control algorithm that is equipped with special functions including, soft start and non-linear cooling. A complete set of process protection alarm functions, high and low limit, band and deviation are included. Optional features include: CT input- HBD OFD, Servo valve positioner, (ma) linear control or retransmission outputs, ModBus communication interface option, Up to 10 event inputs and 8 event outputs. CONFIGURATION PROGRAM Direct connection between the K3P and a PC is possible using the CPI adaptor. The CPI allows easy connection between the built in configuration port and the PC RS232 port (COM1/COM2). PC based EROConfig software speeds and simplifies configuration by providing guided menus for complete instrument set-up, parameter adjustment and program editing. A complete instrument configuration may be saved from, and downloaded to the instrument providing a quick and reliable method to maintain instrument settings. 1250 1250 635 : 5 P S RUN HOLD FN PROGRAMMER FACILITIES Program format Up to 90 simple programs are available, each program may contain: - up to 99 segments - up to 14 timed events Program segment options Up to 200 segments are available, for each segment it is possible to: - set duration in hours and minutes (up to 99hours and 59minutes) or in minutes and seconds (up to 99minutes and 59 seconds) - apply up to 5 different PID sets - apply a wait band (10 available) - apply one or more break events Linked programs - Up to 9 programs may be linked

WAIT AND GUARANTEED SOAK FUNCTIONS Up to 10 program wait bands may be set. If the process variable is outside the programmed wait band, the ramp in progress will be stopped. The program will restart when the process variable is returned inside the wait band. During a program soak segment the temperature set point is maintained for the entire programmed time. If the process variable is outside the programmed wait band, the soak time will be stopped. The soak time will restart when the process variable is returned inside the wait band. Each segment may have different wait bands. Tracking If the process is interrupted during a ramp, the controller will continue the ramp after the process stablizes at the target set point valve. Set point Guaranteed Soak Guaranteed Soak assures the product receives the desired process time at all program segments. Set point Suspension of soak time Temp Temp
K3P ENG.qxd 23/10/2003 12.30 Pagina 4 SPLIT RANGE OF THE OUTPUT Allows two different physical outputs, (two different actuators) to be driven from the same control output. Bias and gain settings for each output may be independently set to achieve optimal control precision. This feature may be used to improve flow control and reduce energy consumption when using two control valves or variable speed pumps of different size, as illustrated in the diagram. 100% Power output 100% Power output 100% Out A + Out B Measure Output calculated by PID algorithm Output A Output B Measure Output calculated by PID algorithm Output A Output B Real Output (it is the sum of the two outputs) Measure SQUARE ROOT EXTRACTION ON THE MEASURED VALUE A square root extraction function is available to calculate flow with a standard DP transmitter without additional signal conditioning hardware. AUXILIARY POWER SUPPLY An un-isolated auxiliary power supply option enables direct connection of a 2, 3 or 4-wire transmitters and eliminates the need for an additional, separate power supply unit. PREPROGRAMMED OUTPUT CHARACTERISTICS Maximum flow percentage 100% 80% 60% 40% Quick opening Linear 20% Equal Percentage 0% 20% 40% 60% 80% Rated travel percentage 100% Quick opening and equal percentage valve flow characteristic are automatically compensated by the output linearisation facility. This function linearises the ratio between flow rate and valve travel in order to obtain a better control of the process.
K3P ENG.qxd 23/10/2003 12.30 Pagina 5 OP1 OP2 OP3 OP4 SEG PRG REMN ALARM ON THE OUTPUT VALUES The control output percentage is monitored by a configurable process alarm. Using this method it is possible to simplify the control of the process. In the example shown, the instrument is controlling a process by driving an airflow valve. The airflow generator uses 3 fans; the first one is always ON while the second and third are turned ON when the power output reaches the programmed value [33 % (AL 1) and 66% (AL 2)]. This solution reduces power consumption and improves process control.
