6.2 Protective Functions
BP4610 6-7
6.2.1 Overload
The BP4610 detects overload in the following cases.
• The output voltage exceeds the limiter value
•
The output current exceeds the limiter value
• The internal power loss (average, momentary) is excessive
•
The DCPS average output power is excessive
Upon detection of overload, the BP4610 displays the overload status, as follows.
•
Upon detection of overload, the
icon flashes and a beep is emitted.
•
If the overload continues for 10 seconds after overload detection, a beep is emitted and the output
is switched off. An error message, listed in Table 6-4, is also displayed.
•
If the overload further continues, the power is switched off. After the BP4610 is powered back on,
an error message, listed in Table 6-2, is displayed.
6.2.2 Over-limiter
If the DC output voltage measurement value exceeds the maximum value of the set voltage limiter
range or is 3 V or more under the minimum value, over-limiter is judged to have occurred. Upon
detection of over-limiter, the BP4610 displays the over-limiter status as follows.
For how to set the limiter values,
refer to “4.4 Setting of Limiters”.
•
A beep is emitted and the output is switched off. An error message, listed in Table 6-4, is also
displayed.
•
If the limiter values are exceeded during output on operation, the output cannot be switched on. In
this case, the status icon ( ) is displayed and an error message, listed in Table 6-3, is
displayed.
