132/2116 Controller 1 DESCRIPTION 1.1 2132 Controller The controller is made by Eurotherm, and is fitted by Carbolite configured for immediate use. It is a digital instrument with PID control algorithms. It is supplied as a sleeve fitted controller, and because of its small size is suitable for products where space is at a premium. The 2132 features: - Easy use as a simple temperature controller, where on setting the required temperature the controller immediately attempts to reach and maintain it.
2132/2116 Controller 2 BASIC OPERATING INSTRUCTIONS 2.1 Furnace or Oven Controls Most Carbolite products are fitted with an “Instrument Switch” which cuts off power to the controller and other parts of the control circuit. See the instruction manual for the furnace or oven for the overall operating instructions. To operate the controller there must be power to the furnace or oven, and the Instrument switch must be on.
2132/2116 Controller 2.5 Stopping and Starting Control It is possible to stop and start the controller without altering the setpoint. Press Scroll until the legend m-A (manual/auto) appears. In the 2132 or 2116, manual means “off” and auto means “on”. Press Down or Up once to show the current on/off state: mAn for off, and Auto for on. Press or to change between manual and auto (off and on) as required. Note that timer modes 1 & 3 set the controller to mAn at the end of the timing period.
2132/2116 Controller 3 OPERATION WITH THE TIMER The 2132 or 2116 can be used as a process timer allowing timed heating or timed delay, according to the options in the table. There are 5 timer modes, but 2 of them are affected by whether the setpoint ramp rate feature is being used, making 7 entries in the table. The table also shows the status of the Timer Light on the controller. A visual impression of the different modes is given in fig 3.
2132/2116 Controller 3.1 Setting the Timer Mode Scroll to tm.OP; use or to view and alter the mode. The mode shows as OPt.1 to OPt.5. It is not possible to alter the mode while the timer is running; if the mode cannot be altered, scroll to the StAt parameter and set its value to OFF. 3.2 Setting the Time Period Method 1 Scroll to tmr (time remaining). Use or to view the remaining time; the units are always in minutes. Use and to set or alter the time.
2132/2116 Controller 3.4 Stopping the Timer To stop the timer at any time while it is running, change the StAt User Calibration parameter to OFF. This is the same as reducing tmr to zero. The controller then acts as though at has reached the end of the time period. 3.5 End of Time Period Modes 1 and 3: heating stops at the end of timing; the m-A parameter changes to mAn. Modes 2 and 4: heating continues at the end of timing; the m-A parameter remains at Auto.
2132/2116 Controller 4 ALTERING THE POWER LIMIT 4.1 Overview Depending on the furnace or oven model the power limit parameter OP.Hi (Output High) may be accessible or hidden. For silicon carbide heated furnaces the parameter is accessible to allow for compensation for element ageing (see the appropriate section in the furnace manual). In wire-heated chamber or tube furnaces, reducing the power limit is a convenient method of improving control at low temperatures, as outlined below.
2132/2116 Controller 5 USER CALIBRATION The controller is calibrated for life at manufacture against known reference sources, but there may be sensor errors or other system errors. User calibration allows compensation for such errors, and the 2132 or 2116 allows for a user 2-point calibration. This setting is password protected to avoid accidental alteration. Page to iP, scroll to CAL.P, and use Up to alter the password. The password is 3. If the correct password is entered, the display shows PASS.
2132/2116 Controller 6 AUDIBLE ALARM If an audible alarm is supplied for use with the timer function, then it is normally configured to sound at the EnD condition, and to go off when the alarm is acknowledged as given in section 3.6. It is not possible to cover in this manual other possible alarm features which may be included by customer special order. 10 .
