Thermal data:
Control unit type CU4** resp. CU4*plus*:
Permissible ambient temperature range during operation: 0 °C ≤ Ta ≤ +55 °C
Double seat valve type D4*:
The permissible ambient temperature range as process temperature (medium or cleaning solutions
temperature) depending on the temperature class is shown in the following table:
Temperature of the medium or cleaning
solution
0°C...80°C
0°C...95°C
0°C...130°C
Assembly type D4*-CU4** / D4*-CU4*plus* 3G consisted of the control unit CU4** resp. CU4*plus* and the
valve type D4*:
Control unit type CU4** resp. CU4*plus*:
Permissible ambient temperature range during operation: 0 °C ≤ Ta ≤ +55 °C
Double seat valve type D4*:
The permissible ambient temperature range as process temperature (medium or cleaning solutions
temperature) is 0 °C ≤ Ta ≤ +130 °C
The reverse heat flow from the process beyond the permissible ambient temperature of the control unit
CU4** resp. CU4*plus* is not possible by construction.
Specific Conditions of Use
1. For the control unit type CU4** resp. CU4*plus* the permissible ambient temperature range during
operation is 0 °C ≤ Ta ≤ +55 °C
For the double seat valve type D4* the permissible ambient temperature range depending on the
temperature class is the medium or cleaning solution's temperature and is to be taken from the
operating instructions.
For the assembly type D4*-CU4** / D4*-CU4*plus* 3G the permissible ambient temperature range
during operation at the control unit type CU4** resp. CU4*plus* is 0 °C ≤ Ta ≤ 55 °C and on the
double seat valve type D4* is 0 °C ≤ Ta ≤ +130 °C
2. Metallic process connection parts of the double seat valve type D4* have to be included in the local
potential equalization.
3. The control unit CU4** resp. CU4*plus* and the plastic base of the double seat valve type D4*
have to be installed and used in such a way, that electrostatic charging from operation,
maintenance and cleaning is excluded.
4. The base of the control unit CU4** resp. CU4*plus* has to be installed in such a way that it is
protected from UV-radiation.
5. The connecting and disconnecting of the pluggable electrical circuits inclusive the field wirings is
only permitted if no explosive atmosphere exists.
6. The control unit type CU4** resp. CU4*plus* has to be erected in such a way that a pollution
degree 2 or better, according to IEC 60664-1, is achieved.
7. Measures have to be taken, external to the control unit type CU4** resp. CU4*plus*, to provide a
transient protection that ensures that the rated voltage, connected to the power supply terminals, is
not exceeded by more than 40 %.
8. To prevent the breaking of the springs, the actuator has to be replaced after 250,000 cycles.
