PPE's IMP (Intelligent Microprocessor) Series Module provides one of the most technically advanced
With SafeChange™ temperature controls available today. IMP modules use state-of-the-art microprocessor-based circuitry
to perform all required PID functions. Units have built-in diagnostics and are fully self-tuning. Setpoint
Hot Swap Feature! temperatures are maintained without the need to manually preset or adjust the control temperature.
Merely set the desired temperature and turn the power on. The module will automatically sense the heat-
up rate and control any setpoint temperature deviation.
CompuStep ®
If desired, CompuStep, may be used during system start-up to remove moisture from the heater before
full power is applied. This function applies low, gradually increasing voltage to the heater over a 5 minute
period and then automatically switches the module to normal operation.
CompuCycle ®
CompuCycle is a unique method of applying power to the heater. This zero crossover power drive
technique improves response time, reduces thermal fatigue and prolongs heater life by applying AC
power smoothly and continuously. Sixty-four different power levels are programmed in the CompuCycle
drive, which can switch smoothly from one level to another within 0.13 seconds as required to achieve and
maintain setpoint temperature. The result is 128 computer controlled power settings available to the
operator. Combined with microprocessor-controlled automatic reset and temperature overshoot suppres-
sion, CompuCycle assures that the setpoint is reached and maintained quickly and accurately.
Manual Control
The CompuCycle power drive is also used with the line voltage compensated manual control mode. This
mode enables the module to be used for non-thermocouple applications. It can also be used to provide
standby or "weekend" heat or to manually control temperature if a thermocouple fails.
