Page 13: R38 Controller
3.0 R38 Controller PID control This controller uses PID (Proportional Integral Derivative) temperature control. This type of control uses a complex mathematical control system to adjust the heating power and achieve the desired temperature. Controller Operation When switched on, the controller lights up, goes through a short test routine and then displays the measured temperature and starts to control. -

Resetting the Over-Temperature To reset the over-temperature controller, power cycle the product by turning the instrument switch off, then on again. Process Timer (if fitted) To set a process time: Press the P key; S.t1 shows momentarily on the display. The display then flashes. Use the arrow keys to adjust the process time, which is in hours and minutes (hr.mn). -
Page 15: Over-Temperature Control (If Fitted)
Over-Temperature Control (if fitted) The over-temperature controller should typically be set at 15 °C above the main controller. If an over-temperature condition occurs, check the main controller is functioning correctly. An over-temperature condition cuts off power to the heating elements. A light in the over-temperature controller flashes. -
