5.1.2 Programming process
You start programming mode by pressing the
PROG
key. Once program-
ming mode has been started, all of the unit’s functions – including the heat-
ing and air flow controls – switch to standby mode.
When you switch to programming mode, you are first requested to enter
your password. You can only make changes to the program if you enter the
correct password (which is 4230) and confirm with
ENTER
.
Once you have entered your password the first main menu appears, which
allows you to assign a measurand or operand to the analogue output. Press-
ing the
ENTER
key has the effect that you are taken to the next main menu
without making any changes. If a sub-menu exists, you open it by pressing
1
. Once you have changed or adopted values using the
ENTER
key you
are taken to the next menu option.
Within the input masks you use the
CLEAR
key to correct entries (see
above).
When you enter values, the system will only accept plausible entries, mean-
ing that they must lie within a certain range. You cannot leave the menu if
the value you have entered is too high or too low. Delete the entry using the
CLEAR
key and enter a different value.
Programming mode is quit automatically following the last menu (SET-
LIMITS). Once you have changed the desired parameters, simply keep
pressing the
ENTER
key until the equipment returns to operating mode.
Due to the fact that the equipment was in standby mode during program-
ming, the temperature may have dropped so far that error messages appear
when you first return to operating mode. The display will correct itself after a
short period of time.
The chart on the next page provides you with an overview of the structure of
the menus in programming mode.
