9 Controller Operation

9.8Controller Configuration

The controller has a number of configuration and operating options and calibra- tion parameters which are programmable via the front panel. These are ac- cessed from the secondary menu after the proportional band function by pressing “SET”. Pressing “SET” again enters the first of three sets of configu- ration parameters: operating parameters, serial interface parameters, and cali- bration parameters. The menus are selected using the “UP” and “DOWN” keys and then pressing “SET”. (See Figure 4 on page 36.)

9.9Operating Parameters

The operating parameters menu is indicated by,

PAr

Operating parameters menu

The operating parameters menu contains the High Limit, Stir Speed, and Cool- ing parameters.

9.9.1High Limit

The High Limit Parameter adjusts the upper set-point temperature. The factory default and maximum temperature are set to 100°C. For safety, a user can ad- just the High Limit down so the maximum temperature set-point is restricted.

HL

High Limit parameter

Press “SET” to enable adjustment of HL.

HL

Flashes “HL” and then displays the setting

H=100 Current HL setting

Adjust the HL parameter using “UP” or “DOWN”.

H=90

New HL setting

Press “SET” to accept the new temperature limit.

9.9.2Low Limit

The Low Limit (LL) Parameter adjusts the lower set-point temperature limit. The factory default and minimum temperature are set to –90°C. For safety, a user can adjust the Low Limit up so the minimum temperature set-point is restricted.
