Page 12: Controller Operation
INTRODUCTION The Series 1900 General Purpose Time/Temperature Controller incorporates three separate user selectable operating Modes; a Time/Temperature mode, a Temperature control mode and a Timer mode. The functionality and programmability of the controller is determined by the specific operating mode selected. The operating mode is changed from within Setup (Refer to the Controller Setup Programming section below). In Time/Temperature Mode the user can preprogram the run temperature (SP1) and the run time of a heating cycle. At the conclusion of this timed cycle the controller can be programmed to hold the process indefinitely at a second set point temperature (SP2) or to turn off the heat completely. Pressing the START/STOP button starts the run timer and causes the controller to begin heating to the SP1 temperature. The controller will maintain this temperature until the timer reaches 0 then, depending on user programming, the oven will shut off or the set point temperature will change to the SP2 set point. The Temperature Control Mode operates as a normal single loop temperature controller. In this mode the process will be maintained at the user programmed temperature set point continuously while power is applied to the controller. In the Temperature Control Mode the START/STOP button toggles the controller display and output On & Off. In Timer Mode the controller functions as a preset countdown timer. When a timing cycle is initiated by pressing the START/STOP button the output relay will be energized. At the end of the timing cycle the relay will de‐energize and the buzzer will sound. Refer to the Controller Operation section for more details on these operating modes. CONTROLLER OPERATION INITIAL POWER UP When power is applied to the controller the revision level of the installed firmware is displayed for a few seconds while diagnostic tests are performed. If the tests are completed successfully the controller will automatically return to the last used operating mode. If a problem is detected the controller will be disabled and an appropriate error code displayed (Refer to the Troubleshooting section below). After correcting the problem power to the controller must be cycled off and back on to clear the error. VIEWING/CHANGING SET POINTS ... - Page 13 maximum and minimum values allowed for any set point is determined by the respective Max/Min values set in Setup. Refer to the Controller Setup Programming section below. A Time set point is changed in two steps, first the two right hand digits (Secs or Mins) then the two left hand digits (Mins or Hrs). This allows large time changes to be made more quickly. The digits currently being changed blink on and off. The SET button saves the new value and shifts programming to the next two digits. A Temperature set point is changed one digit at a time beginning with the right most digit then the center digit and finally the left most digit. This allows large set point changes to be made much more quickly. Pressing the SET button shifts programming to the next digit to the left. The digit currently being changed blinks on and off. TIME/TEMPERATURE (OP1) In Time/Temperature mode the normal (idle) display is the Run Time SP. If the Preheat function is enabled the heat output will be energized immediately when power applied to the controller. The output will remain on and the display will flash “PrHt” until the SP2 set point has been achieved then the Run Time SP is displayed. To initiate a Timed temperature cycle press START/STOP. The controller will immediately begin heating the oven to the SP1 set point and the timer will begin counting down. The time remaining in the cycle will be continuously displayed while the timer is running. Actual oven temperature can be momentarily displayed by pressing the set point knob. When the timer reaches 0 the beeper will sound if enabled. If the Hold function is enabled the controller will begin controlling to the SP2 set point and “HoLd” will be displayed. Pressing START/STOP will reset the timer returning the display to the normal idle state (Time SP displayed) ready for another cycle. If Preheat is enabled the controller will continue to maintain the oven temperature at the SP2 set point until a new cycle is initiated. If Preheat is disabled the output will be de‐energized until another cycle is initiated. If the Hold function is disabled the controller output will immediately de‐energize when the Timer reaches 0 and “End” will be displayed. Pressing START/STOP will reset the timer returning the display to the normal idle state (Time SP displayed) ready for another cycle. The Temperature and Time points can all be changed at any time. See Viewing/Changing Set Points section above. Temperature set point changes are always retained in memory and become the default temperature set points whenever the controller is powered on. Time set point changes made while the controller is idling (timer not running) will be also be saved and become the default time set point when the controller is powered on. However, time changes ...
- Page 14 The Hold and Preheat functions are related in that the SP2 set point applies to both the Hold and Preheat functions. Also, in order for the Preheat function to be on the Hold function must also be turned on. If the Hold function is turned off then the Preheat will automatically be turned off as well. The Hold function can be turned off in Setup or on the fly by reducing the Hold set point until OFF is displayed. If power is interrupted while the timer is running the heating cycle will be aborted and “PL” will be displayed when power is restored. Press START/STOP to clear the error message. TIMER MODE (OP2) In Timer mode the normal (idle) display is the Time set point. At power up the previously used Timer set point is displayed and the output relay remains de‐energized. The Time set point can only be changed while the Timer is idle (not running). See Viewing/Changing Set Points section above. When the set point is changed it is retained in memory and becomes the default set point the next time the controller is powered on. Press START/STOP to start the Timer countdown. The output relay will energize and the display will show the time remaining in the cycle. Pressing START/STOP while the timer is running immediately aborts the cycle, de‐energizes the relay and resets the Timer. If enabled, the beeper will sound. The Time remaining can be changed on the fly while the Timer is running by pressing SET. See Viewing/Changing Set Points section above. Note that changes to the time remaining will only apply to the current time cycle and will NOT be retained for subsequent cycles. If power is interrupted while the Timer is running the time cycle will be aborted and “PL” will be displayed when power is restored. Press START/STOP to clear the error message. TEMPERATURE MODE (OP3) When power is first applied in Temperature mode the display and output will be Off. Pressing the START/STOP button will turn on the display and the controller will immediately begin controlling to the set point temperature. When set point is achieved the output relay will cycle on and off as required to maintain the process at the set point temperature. The set point can be changed at any time. See Viewing/Changing Set Points section above. When a set point change is made the new set point is retained in memory and becomes the new default set point the next time the controller is powered on. The set point temperature is displayed by default. Pressing the knob causes the actual ...
- Page 15 AUDIBLE ALARM The audible alarm action is determined by the Alarm Mode setting in Setup. In auto mode the buzzer automatically stops after several 1 second bursts. In continuous mode the buzzer will continue to emit 1 second bursts until manually silenced by pressing a button. When turned off the buzzer is disabled. SELECTING SENSOR TYPE The user selectable sensor function is currently disabled. The factory programmed sensor type is displayed when the “SnSr” menu is selected in setup.

Page 17: Troublehooting
TROUBLEHOOTING SENSOR FAULT (Error message “Prb”) The sensor input is continuously monitored for a Thermocouple break or an open/shorted PRTD. If a sensor fault is detected the current cycle is aborted, the output relay de‐energizes and the “Prb” error message is displayed. Check for a faulty sensor, loose sensor connection or open/shorted sensor leads. After the fault has been corrected power to the controller must be cycled off and back on in order to clear the error. MEMORY ERROR (Error message “Err”) User programmed parameters are stored in non‐volatile memory for a minimum of 10 years. Should this memory become corrupted the controller will be disabled and “Err” will be displayed. Restoring the controller to the factory default condition should correct the problem. Refer to “Restoring Factory Defaults” below. RESTORING FACTORY DEFAULTS It is sometimes helpful while troubleshooting to restore the controller to a known operating condition. All parameters can be restored to their factory default values by holding the SET and START/STOP buttons while applying power to the controller. Note that all user programmed parameter values will be lost when factory defaults are restored.
