Inputs/Outputs
Digital Input
[Disabled]
Use Digital Input to configure the functional operation of the digital input. The following functions
aresupported:
• Remote Reset – Clears totalizer T2 (uni-directional)
• Batch Reset – Resets batch totalizer PS to preset amount and clears T2 (uni-directional)
• Pos Zero Return – Forces flow rate to zero (does not totalize)
• ADE – Input configured for ADE operation. See “Encoder Protocol Interface” on page 57.
To change Digital Input, follow these steps from the Inputs/Outputs menu:
1. Select Digital Input to view the Digital Input display.
2. Select a function.
3. Press [E] to save the digital input and return to the Inputs/Outputs menu.
Apply an external potential of 5…30V DC or an internal voltage source of 24V DC via output #2 to
enable input switching (by a normally open contact). If using the internal source, set the function of
digital output #2 to “24V DC Supply”. Jumper JP2 must be placed.
Digital Output Pulses/Unit
[1 pulse/unit]
S
The Pulses/Unit parameter lets you set the number of pulses per unit of measure
transmitted to remote applications. For example, assuming the unit of measure
isgallons:
• Setting the Pulses/Unit to 1 transmits 1 pulse every gallon
• Setting the Pulses/Unit to 0.01 transmits 1 pulse every 100 gallons
You must configure pulses/unit if the function of the selected output is forward,
reverse or AMR pulse.
Consider this parameter with the Pulse Width and Full Scale Flow parameters. The
maximum pulse frequency is 10 kHz. The frequency is correlated with the flow rate.
Violation of output frequency limits generates a configurationerror.
To change the pulses/unit, follow these steps from the Inputs/Outputs menu:
1. Select Digital Output 1 or 2 and press [E] to open the Digital Output menu.
2. From the Digital Output menu select Pulses/Unit, and press [E] to open the
Pulses/Unit display.
3. Enter the pulses/unit value. Press [E] to save the new parameter and return to
the Digital Output menu.
Pulse Width
[0 ms]
S
Use Pulse Width to establish the On duration of the transmitted pulse. The
configurable range is 0…1000 ms.
• Non-zero pulse width configuration, the Off duration of the transmitted pulse, is
dependent on flow rate. The Off duration should be at least the configured On
duration range. At Full Scale Flow, the On duration equals the Off duration. The
maximum configurable output frequency is limited to 500 Hz.
• 0 ms pulse width configuration, the duty cycle of the transmitted pulse, is at
50% allowing for a maximum configurable output frequency of 10 kHz.
Consider this parameter with the Pulses/Unit and Full Scale Flow parameters. The
maximum pulse frequency is 10 kHz. The frequency is correlated with the flow rate.
Violation of output frequency limits generates a configurationerror.
To change the pulse width, follow these steps from the Inputs/Outputs menu:
1. Select Digital Output 1 or 2 and press [E] to open the Digital Output menu.
2. From the Digital Output menu select Pulse Width and press [E] to open the
Pulse Width display.
3. Enter the pulse width value. Press [E] to save the new parameter and return to
the Digital Output menu.
