4 Setting up the controller

Before using the controller (or during its lifetime) certain parameters may have to be set,

depending on specific requirements. To do this the controller must be set to supervisor level

(Level 2) see section 3.4

4.1 Set Point Ramp Rate (3216CC only)

To control the rate at which the temperature rises to sepoint, the SP.RATE function is used.

Before setting the ramp rate, it is advisable to set the setpoint to a low value, preferably 0°C

(see section 3.2). Once the ramp rate has been set the required setpoint can be entered

from the home menu. Doing so will activate the ramp rate, which can be identified with the

run indicator showing on the bottom of the display. While the ramp rate is active the working

setpoint will be shown on the lower temperature display (This is the setpoint, set by the

ramp rate).

When the process temperature has reached the setpoint value at the given ramp rate, the

run indicator will turn off and the instrument will control at the required Setpoint temperature.

Any further modifications to set point will cause the ramp rate to be activated and the

instrument to control as described above.

NOTE: Ensure timer configuration is set to ‘none’ (Section 5.1) to use the setpoint ramp rate

feature without any timer functions.

Press scroll  until the display shows SP.Rate <setpoint rate limit>. Using Up and

Down  select the ramp rate required, in °C/Min.

To check the Setpoint during ramping press the Up or Down once.

To cancel the ramp rate, the SP.Rate <setpoint rate limit> must be set to OFF.

4.2 Maximum Output Power Setting

Press scroll  until the display shows OP.HI <Output High>. Using Up and Down 

select the output power required as a percentage.

Depending on the furnace or oven model, the maximum output power setting OPHi may be

accessible or locked.

For Silicon Carbide heated furnaces, the parameter is accessible to allow compensation for

element ageing. Refer to the product manual for details.

In many models the maximum output power setting depends on the supply voltage, refer to

the product manual for details.
