RCU database controls
This control issues commands to all phases to set/clear their no-reclose protection off bit
but only if communications are normal to each and every Fusesaver and no Fusesaver has
its external lever down. If communications have failed to any Fusesaver or any Fusesaver
has its lever down, then no command will be sent to any Fusesaver.
Controls will only be accepted if D_PID 101 (remote control enabled) is set. If not, then
control will be rejected with the relevant control response code.
This control sets and clears DPID_138, primary test mode.
Control will always be accepted irrespective of D_PID 101 (remote control enabled).
When primary test mode is set, in-service switching operations counting is disabled (refer
A_PID 26-28 operations counter), (e.g., to exclude operations that have been carried out
by testing staff during installation).
This control turns on/off the Fusesaver forced protection mode. Set command will issue a
command to turn the Fusesaver forced protection mode on. Clear command will issue a
command to turn the Fusesaver forced protection mode off.
Controls will be sent to any Fusesavers, which are configured and to which
communications are normal. Controls will only be accepted if D_PID 101 (remote control
enabled) is set. If not, then control will be rejected with the relevant control response
code.
When turned on, forced protection arming will automatically turn off after a configurable
period defined in the Fusesaver to reduce battery drain.
