7.4.4 Sequencer Status Indicators
When the sequencer is enabled, the control path indication field on the keypad will indicate SQx, where x
represents the active state of the sequencer. A sample operate screen (where the sequencer is in state
1) is shown below:
Bits 4, 5, 6

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
0.01 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.”

The sequencer will never advance if this option is selected.
