Method for operating a temperature-limiting device, temperature-limiting device and electrical apparatus

摘要

In a method for operating a temperature-limiting device of an electrical unit activatable for a limited time period by way of an activation signal, the temperature-limiting device permits activation of the electrical unit upon occurrence of the activation signal only if a counter value is greater than or less than a reference value, the counter value being incremented or decremented by a determined temperature equivalence value upon each activation of the electrical unit.

1. A method for operating a temperature-limiting device of an electrical unit activatable for a limited time period by way of an activation signal, comprising:
adjusting a counter value in the following manner: (i) the counter value is decremented at a predetermined rate of change; and (ii) the counter value is incremented by a determined temperature equivalence value only once upon each activation of the electrical unit; adjusting a reference value such that the reference value is set to a first reference value when the counter value falls below a minimum value, and the reference value is set to a second reference value when the counter value exceeds a maximum value, wherein the second reference value is less than the first reference value, the minimum value corresponds to the second reference value, and the maximum value corresponds to the first reference value; and permitting, by the temperature-limiting device, activation of the electrical unit upon occurrence of the activation signal only if the counter value is less than the reference value.
