Bandlimits are active during external control.
Various settings are possible for the heat-up and cool-down
phases as required.
Setting range: 0 °C ... 200 K
>
Upper bandlimit
< and >
Lower bandlimit
< define the
maximum permissible temperature difference between the internal
bath and the external system during the heat-up or cool-down
phase, respectively.
During the heat-up phase, this difference value is always added to
the current external temperature. During the cool-down phase, the
difference value is subtracted.
Reasons for setting limits:
Protect the object being controlled with gentle temperature
control.
Protect glass reactors or other objects from thermal tension.
As long as >Bandlimit selftune< is engaged, the bandlimit will
be switched off during external control (see page 24 ).
