4.3.19 Event Input Function
The Event Input Function is used to select the desired mode of operation for the digital input of the limit control
board. The event input selections are mutually exclusive, i.e., selecting one will turn off the others. Once the
desired function has been selected, press the “Done” button to set the event input function for the limit control
and return to the main Limit Configuration screen.
When
Remote reset is selected for the event input function, the event input will perform an alarm reset each
time the input terminals go from open to closed.
When
Remote lock is selected for the event input function, the event input will lock and unlock the front panel
of the L41 limit control. When the input terminals are opened, the keys will be unlocked allowing a user to
adjust the limit and alarm set points from the front of the L41. When the terminals are closed, the keys will be
locked preventing adjustment of the limit and alarm set points from the front of the L41.
NOTE: Any setting changes made from the MCTB display via the Configurator or runtime application will
unlock the front panel of the L41. The L41 will automatically lock the front panel after several minutes
of inactivity regardless of the event input state.
