1DESCRIPTION

1.1 2132 or 2116 Controller

The models 2132 and 2116

overtemperature controllers are

made by Eurotherm, and are fitted

by Carbolite Gero configured for

immediate use. The two models

are the same except for the size.

They are digital instruments with

a latching alarm, requiring no

additional panel controls.

The 2132/2116 features easy setting of overtemperature setpoint, and reading of current

temperature at the overtemperature sensor.

The controller does not contain a real-time calendar, and is not subject to century-end date

problems.

2BASIC OPERATING INSTRUCTIONS

2.1 Furnace or Oven Controls

Most Carbolite Gero 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 2132/2116 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.

When an overtemperature condition occurs, the controller cuts the power to a contactor, which in

turn cuts power to the heating elements. Power is not restored until the controller is “reset”.

Other components do not generally have power to them cut on overtemperature; oven fans

usually remain running, but may not do so if other options (such as a door switch) are fitted.

2.2 The 2132/2116 –Operation

When switched on, the controller lights up, goes through a short test routine, and then displays

the measured temperature or the overtemperature setpoint.

The Page key allows access to parameter lists within the controller; most lists and parameters

are hidden and cannot be accessed by the operator because they contain factory-set parameters

which should not be changed.

A single press of the page key displays the temperature units, normally set to °C; further

presses reveal the lists indicated in the Navigation Diagram in section 4.

The Scroll key allows access to the parameters within a list. Some parameters are display-

only; others may be altered by the operator.

A single press of the scroll key in the Home list displays the temperature units; further presses

reveal the parameters in the current list indicated in the Navigation Diagram.

To return to the Home list at any time, press Page and Scroll together, or wait for 45

seconds.

The Down and Up keys are used to alter the setpoint or other parameter values.

2.3 Basic Operation

Use Down and Up to alter the overtemperature setpoint. This should normally be set a

little above the maximum working temperature (say 15°C above). The unit is supplied at 15°C

above the furnace or oven maximum working temperature.

Press Scroll to view the present temperature as seen by the overtemperature controller. Press it

twice, because the first press shows the temperature units (°C).

2.4 Overtemperature Alarm

If an overtemperature condition occurs, the OP2 indicator flashes, and an alarm message 2FSH

also flashes, alternating with the setpoint. Power to the heating elements is disconnected.

2.5 Resetting the Overtemperature Alarm

To acknowledge the alarm press Scroll and Page together.

If the alarm is acknowledged while there is still an overtemperature condition, the OP2 indicator

stops flashing but continues to glow. The 2FSH alarm continues to flash until the over-

temperature condition is cleared (by the temperature falling), when normal operation resumes.

If the alarm is acknowledged when the temperature has dropped (or after the overtemperature

setpoint has been raised) such that the overtemperature condition no longer exists, then the

furnace or oven immediately resumes normal operation.

2.6 Sensor Break

The overtemperature cut-out system also operates if the overtemperature control thermocouple

breaks or becomes disconnected. The message S.br flashes instead of 2FSH.

3AUDIBLE ALARM

If an audible alarm is supplied for use with the overtemperature controller, then it is normally

configured to sound on overtemperature condition, and to stop sounding when the alarm is

acknowledged as given in section 2.5. Note that the alarm may sound during controller start-up.

It is not possible to cover in this manual other possible alarm features which may be included by

customer special order.
