12.2.3.13 Thermal overload protection holding the auto recloser back
If the THOLHOLD input (thermal overload protection holding auto reclosing back) is activated, it will
keep the auto recloser on a hold until it is reset. There may thus be a considerable delay between
start of the auto recloser and the breaker closing command to the circuit breaker. An external logic
limiting the time and sending an inhibit to the INHIBIT input can be used. The input can also be used
to set the auto recloser on hold for a longer or shorter period.
12.2.4 Setting guidelines
12.2.4.1 Configuration
Use the PCM600 configuration tool to configure signals.
Auto recloser function parameters are set via the local HMI or Parameter Setting Tool (PST).
Parameter Setting Tool is a part of PCM600.
