set point

Common value: 5.0 vol.-% (factory setting), or depending on the NaHCO

concentration of the culture medium (Figure 27 page 55).

0.0 °C to 60.0 °C

Safety controller set point when set point type is “Limit” (Lit)

Limit value, i.e., maximum permitted absolute temperature value. When

exceeded, the safety controller triggers an alarm. For technical reasons,

the limit value should exceed the temperature set point by at least 2 °C.

Typical value: 39.0 °C / 102.2°F.

0.1 K to 10 K

Safety controller set point when set point type is “Offset” (OFS)

Offset value, i.e. maximum over temperature above the selected set point

When exceeded, the safety controller triggers an alarm. For technical

reasons, the offset value should be at least 2 °C (factory setting).

0 to 999

Max. 3-digit numeric password for locking/unlocking the operating func-

tion setting in operating mode LOCK (chap. 7.4)

To permit temporary unlocking: select any password ≠ 0.

To permit permanent unlocking: set password to “0”.

The operating function “At.S” in operating mode USER (chap. 7.3) specifies the safety control-

ler set point type “Limit” (Lit) or “Offset” (OFS).

With set point type “Limit” (Lit), operating function “AL.S” (safety controller set point as limit

value) is displayed in operating modes HAND and USER. You can set a limit value.

With set point type “Offset” (OFS), operating function “Ot.S” (safety controller set point as

offset value) is displayed in operating modes HAND and USER. You can set an offset val-

ue.

With set point type “Limit”, set the safety controller each time the set point for the temperature

is changed. Set the safety controller set point approx. 2 °C above the controller temperature

set point.

Factory setting: set point type “Offset” with safety controller set point 2 °C.
