RAMPTROL

This microprocessor-based ramping controlprovides four-file/24-step program capability

or easy-to-use non-ramping set-point operation. Ramping operations include four

files with six steps each. Programming options include ramp-rate or time-based

profiles, guaranteed soak deviation, program looping, and program status selection after

power outage. Files may be linked to create a single, 24-step program. Also allows

automatic setting of control parameters with little user input. RampTrol automatically

sets the PID parameters (proportional band,reset/integral, and rate/derivative) through a

“learning” sequence in the auto-tuning mode.The primary analog input is a thermocouple.

The back panel features a nine-pin serial port for communication with a PC. A secondary

output is available for cooling, along with a 4-20ma retransmit output for temperature

recording and an RTD input. Information is stored in non-volatile memory.
