3.2.2 Temperature
60W
Temperature is monitored at several points within the unit. High voltage generation is stopped in case the internal temperature
of several modules exceeds a predefined limiting value.
WARNING!
WARNING!
High voltage generation is reactivated immediately if the limit values are no longer exceeded.
150W
The temperature of the inlet air and several modules is monitored in the high-voltage supply. Exceeds the temperature at one of
the measuring points the permissible value, the high-voltage generation is stopped immediately and an error register is set. This
error register still blocks the high-voltage generation, even if the monitored temperatures are again in their allowed limits. To
reset the error register, INHIBIT must be activated (set to low).
3.2.3 Switch-on monitoring
–
EPS 150W
When the device is switched on by applying the supply voltage, an error register receives a set command for a period of 350 ms.
This prevents unwanted high-voltage generation. The error state can only be reset after this time by an activated INHIBIT signal. If
operation without the INHIBIT function is desired, e.g. to control the device exclusively with ON, the following options are
available:
•
INHIBIT is activated by a higher-level circuit after a duration of 350 ms after the supply voltage has been applied and
then deactivated, or
•
a capacitor with a capacitance of at least 100 µF is connected between INHIBIT and GND, by which the INHIBIT signal is
activated for a period of 400 ms after the supply voltage is applied and is then deactivated
•
this function can optionally be disabled at the factory.
