PT100 autoreset [2522]
The delay counter starts counting when all PT100 inputs are
below the set temperature in menu [2322].
PTC autoreset [2523]
The delay counter starts counting when all PTC values are
below their respective limit. This means that if e.g. only the
internal power board PTC (PB-PTC) is present, the PTC
resistance has to go down to 2,260 Ohm before the delay
time to autoreset starts counting down. I.e. the total time
until autoreset is performed is the time until PTC reaches
2,260 ohm + the set delay time in menu [2523].
For corresponding resistance limits regarding PTC option
boards, please refer to the PTC/PT100 board 2.0 instruction
manual.
Locked Rotor autoreset [2524]
In this menu the delay time for an autoreset of a locked rotor
alarm is set. As a locked rotor cannot be detected in stopped
state, the delay time starts counting immediately after the
alarm action has been executed. When the delay time has
elapsed, the alarm will be reset.
Current Limit autoreset [2525]
In this menu the delay time for an autoreset of a current limit
alarm is set. As a current limit fault condition cannot be
detected in stopped state, the delay time starts counting
immediately after the alarm action has been executed. When
the delay time has elapsed, the alarm will be reset.
Communication Error autoreset [253]
The delay counter starts counting as soon as communication
is reestablished.
Process Protection Autoreset [254]
When the load monitor function is used, menu group [410],
the following settings for autoreset can be done.
Load Monitor Max Alarm autoreset
