P55 Analog Input Trip Type I/O 08
LED Display LCD Display
Range LED LCD Description
OFF Off Off, Disabled. (Default)
Lo Low Level Low, Fault if input signal below preset trip level.
H I High Level High, Fault if input signal above preset trip level.
Description The analog input is the reference input for a starter configured as a Phase Controller or Current Follower. In
addition, the Analog Input Trip Type parameter allows the user to set a "high" or "low" comparator based on
the analog input. If the type is set to" Low", then a fault occurs if the analog input level is below the trip level
for longer than the trip delay time. If the type is set to "High", then a fault occurs if the analog input level is
above the trip level for longer than the trip delay time. This function is only active when the motor is running.
This feature can be used in conjunction with using the analog input as a reference for a control mode in order
to detect an open 4-20mA loop providing the reference. Set the Analog Input Trip Type parameter to "Low"
and set the Analog Input Trip Level (P56 / I/O 09) parameter to a value less than (<) 20%.
z NOTE: The DIP switch (SW1) on the card changes the analog input and analog output between 0-10V or
0-20mA. See Figure 18 to see DIP Switch Settings. ANALOG INPUT SW1-1 ANALOG OUTPUT SW1-2.
