Table 8: programme setpoint
The programme setpoints are calculated according to the programme resp. temperature curve entered by the
operator. Some adjustments are possible for easy operation. Automatic setpoint calculation required for
cascade control systems is also entered by the following settings
(options END, CON, MOD, CHA)
The following basic types creating a setpoint can be selected:
CON: Use initial value of the programme segment only. Typical applications are offset values for zone
temperatures or flap positions
MOD: Programme setpoint modulated by the segment time. This is the common setting causing the
programme setpoint to count upwards resp. downwards over the segment time (e.g. within 2:00 hours from
0°C up to 1000°C)
CHA: Setpoint calculated by cascade control algorithm - for details refer to the example below
following parameters apply on selection CON only:
(value range CH/Z2 to TA04)
Selects the column of the programme table used for setpoint calculation. TA01 is the 1st column, ie. usually the
primary temperature
(value range OFF, SP00 to SP02)
Defines a setpoint which refers to an existing setpoint, ie. the setpoint is calculated by adding another setpoint
to it. Used e.g. for the setpoint of the slave zones of a multizone kiln. Using this option allows the operator to
enter the temperature of the slave zones as offset (temperature difference) relative to the master zone
setpoint. In this example the master zone setpoint is entered in this option
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature
