E N TE R
Range: Self-resetting / Latched
Select Latched to maintain the Output 1 (2-8) contacts in the energized state,
even after the condition that caused the contacts to operate is cleared, until
a reset command is issued (or automatically after one week). Select Self-
reset to automatically de-energize the contacts after the condition is cleared.
The solid state output (Output 1) remains closed until externally reset by a
momentary interruption of current, unless wired in parallel with an
electromechanical relay (Outputs 2-8) in which case it turns off when the
relay operates.
Range: Trip / Alarm / Control
Select Trip to turn the TRIP indicator on or Alarm to turn the ALARM indicator
on when this output operates. Otherwise, select Control .
Note that the TRIP indicator remains on until a reset command is issued (or
automatically after one week). The ALARM indicator turns off automatically
when the output is no longer operated.
Range: any FlexLogic™ input or gate
