1. Tmp in fahrenheit

Set this parameter to Y

if all temperature settings and displays should be displayed in

Fahrenheit units instead of Celsius. If this parameter is N

, all temperature settings and

displays will be displayed in Celsius units.

Note: This value only changes the units used for displaying temperature values. Internally
the controller always works with Fahrenheit units.

2. Maintenance cycle

Use this parameter for setting the number of batches until a maintenance request is done. If,
for example, the value of this parameter is 500 then as soon as 500 batches have been done
the controller will show the message Maintenance request when the machine is in rest. The
maintenance counter can be reset again in the System Setup menu, item Reset maintenance
request (see Section 4.7.4 on page 34). The number of batches which still can be done until
a maintenance request is displayed, can be read in the non-resettable counters screen (see
Section 4.4.4 on page 20).

If this parameter is set to 0, the maintenance request option is disabled and no maintenance
request will be displayed.

3. Finished beeptim.

When a program is finished, the controller will activate the beeper. This parameter is the
time the beeper will beep when a cycle is finished. This time is repeated every 2 minutes
until the door has been opened.

4. Overview status

This parameter is used to control the 2

line in the display in the overview screen when the

machine is running.

• Value 0: Toggle between current time left (see value 1) and current temperatures and

step (see value 2)

• Value 1: Only show current temperature, temperature set-point and current step.

• Value 2: Only show time left in current step and total time left until program is finished.

5. RS485 Stationnr.

The controller is equipped with an RS485 port to communicate with a PC for download-
ing translations and monitoring. Every controller in a network must have a unique station
number. This parameter is used to set the station number of this controller.

6. RS485 baudrate

This parameter is used to adjust the communication speed of the RS485 port used for net-
working multiple controllers and communication with a PC.

• Value 0: 115,200bps

• Value 1: 38,400bps

• Value 2: 9,600bps
