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 Basic Operating Instructions 1.4 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. If a time switch is included in the furnace or oven circuit, this must be in an On period.
2132/2116 Controller 1.8 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 2 ALTERING THE POWER LIMIT 2.1 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 3 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.
