ESCRIPTION 201 Controller The model 201 controller is made especially for Carbolite by Eurotherm, and shares many of the features of the Eurotherm 2000 range, especially the model 2132. It is a digital instrument with PID control algorithms. It is supplied as an integrated part of the control section of the oven or furnace.
To operate the 201 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.

Stopping and Starting Control It is possible to stop and start the controller without altering the setpoint. Press Scroll until the legend (manual/auto) appears. In the 201, manual means “off” and auto means “on”. Press Auto Down or Up once to show the current on/off state: for off, and for on.
In many models the power limit setting depends on the supply voltage; usually the furnace or oven manual contains details: if in doubt, contact Carbolite for advice. The power limit parameter does not apply to the overtemperature controller, if present.
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 201 allows for a user 2-point calibration. This setting is password protected to avoid accidental alteration.
