Figure: Error messages that may be displayed if a short circuit occurs in the touch probe during
operation
The PLB 62xx and the UEC 11x feature "polyfuses."
Polyfuses are electronic fuses that become highly resistive if an overload occurs and thus
separate defective peripherals (e.g., touch probes) from the low voltages of the PLB 62xx or
the UEC 11x.
Polyfuses have a self-resetting function ("self-healing effect").
