7.7 Controller 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”. The display flashes “COnFIG” and then displays “Par” for
the first of three sets of configuration parameters — operating parameters, se-
rial interface parameters, and calibration parameters. The sets are selected us-
ing the “UP” and “DOWN” keys and then pressing “SET” (see Figure 3 on
page 20).
7.8 Operating Parameters
The operating parameters menu is indicated by,

HL (High Limit) parameter. The HL parameter adjusts the upper set-point tem-
perature. The factory default and maximum are set to 350°C. For safety, a user
can adjust the HL down so the maximum temperature set-point is restricted.
