6.1 Setting range
6.1.1 Controller
- The temperature setting is done through turning the setting ring (pos. 50.13). The body
(pos. 50.5) must be held fast; it is not allowed to turn.
- Setting of higher ranges is allowed without any restrictions.
- Setting for lower ranges when installed, is only allowed in small steps smaller 30 K.
Between the steps, the temperature regulation (system dependent about 15 min.) must be
waited for.
- When alterations larger than 30 K are done, the excess temperature indicator can
respond.
This can be seen when the setting ring (pos. 50.13) has moved upwards from the body
(Fig. 7) (pos. 50.5). In this case, the temperature regulation must be waited for, before
further alterations are done. Excess responses from the indicator shortens the lifetime
from the thermal controller!
- After the temperature regulation in the system has been fulfilled, the actual temperature
can be seen on the control manometer.
- If both values which have been set are reached, then the procedure is ended.
- If the values are not correct, then a correction must be done on the set point indicator. The
set point must be altered to the actual value (see point 6.2).
