programmed into this parameter can be from 0 to 65,535, and can represent time, pulse counts,
analog voltage thresholds, analog current thresholds, or digital comparison values.

Description of Seq Count Function
000
Time Base - The current sequencer state will last for a time interval equal to the number “Seq Count
X” multiplied by the time base configured in the Seq Appl parameter.
Seq Appl Setting Time to Advance Maximum Sequence Time
1 sec Base (1 sec) * (Seq Count X) 18.2 hours
.1 sec Base (0.1 sec) * (Seq Count X) 1.82 hours
0.1 sec Base (0.01 sec) * (Seq Count X) 10.92 minutes
001
Pulse Count - The current sequencer state will last until the number of pulses programmed into “Seq
Count X” is detected on terminal Vin1.
010
Low Analog Voltage Threshold - The active sequencer state lasts until the voltage signal applied to
terminal Vin2 is < a value programmed into “Seq Count X.” The value programmed into “Seq Count
X” should be the percentage of input after span and offset are applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in parameter 912, Vin2 Status.
011
High Analog Voltage Threshold - The active sequencer state lasts until the voltage signal applied to
terminal Vin2 is > a value programmed into “Seq Count X.” The value programmed into “Seq Count
X” should be the percentage of input after span and offset are applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in parameter 912, Vin2 Status.
100
Low Analog Current Threshold - The active sequencer state lasts until the current signal applied to
Cin terminals is < a value programmed into “Seq Count X.” The value programmed into “Seq Count
X” should be the percentage of input after span and offset are applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in parameter 911, Cin Status.
101
High Analog Current Threshold - The active sequencer state lasts until the current signal applied to
Cin terminals is > a value programmed into “Seq Count X.” The value programmed into “Seq Count
X” should be the percentage of input after span and offset are applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in parameter 911, Cin Status.
110
Digital Comparison - The active sequencer state lasts until the binary value of digital inputs
configured to Seq1, Seq2, and Seq3 is equal to the value programmed into "Seq Count X."
Note: For this option to work, "DIx Configure" parameters must be set to "Seq1," "Seq2," and "Seq3.”
