Digital Input Setup Screen
For all configured digital inputs, the user may edit: a) Signal Type - Select one of three choices; normally open, normally closed DC+ or normally closed DC-. b) Signal Filter - Select None to disable filter function for the digital input. This will not disable the digital input for normal operation.
Select Pulse for lubricator divider blocks with a proximity switch output.
Select DB to debounce or delay input detection for unstable inputs such as surge tank level.
c) Filter Timing - Delay time in seconds for the selected filter type.
For Pulse, this delay is the transition time for the lubricator divider block to cycle.
For DB, this is the duration the digital input must remain either ON or OFF before the input will be recognized and accepted as ON or OFF by the sequence. If the input does not remain ON or OFF for the duration of the delay, the timer will reset. d) Raw Status: The actual measured sensor state. e) Total Pulsed - Total number of pulses counted when the filter type is set to Pulse. The value is expressed in hundreds of pulses. A displayed reading of 1 is equal to 100 pulses. (*only visible on pulse filter types) It may be reset on this display line as well.
Pulse Input Status Screen
Pulsed inputs are designed to accept a cycling digital output from a lubricator divider block, typically from a general purpose proximity switch.
The user may view information about the pulsed inputs. If a digital input is designated for use as a pulsed input, it will display how much time elapsed before the last transition and how much time has elapsed since that transition. If the input is not designated as a pulsed input, there will be zeros displayed. Both have a maximum value of 999.
