·
On - Reverse Flow
- Any output set to AUX 1 Calibration Mode Settings will be off when
a delivery starts, and will only turn on when the register detect flow in the negative or
reverse direction.
·
Reset Pulse/Delivery Start
- Any output set to AUX 1 Calibration Mode Settings will
output a short pulse at the start of a delivery that is used with 3rd party remote counters
that require a reset pulse to reset to 0.0.
·
Toggle Flow Rate
- Any output set to AUX 1 Calibration Mode Settings will turn on once
the flow rate of the LCR.iQ exceeds the set flow rate point in the Auxiliary 1 Flow
RateToggle field below.
·
Calibrated Scaled Pulse Output
- Any output set to AUX 1 Calibration Mode Settings will
output a calibrated pulse output–that is scaled according to the Pulse Output Frequency
setting in the calibration mode.
Auxiliary 1 Flow Rate Toggle
– A numeric text field that can be used to program a flow rate
set point when the Aux 1 is set to Toggle flow rate. Auxiliary 1 remains activated above the set
flow rate value and deactivates when the flow rate falls below the value.
A common use for this output is an air operated valve (AOV) on the pump. When the flow rate
value is attained, the AOV is activated and switches the pump from low-bypass pressure
mode to full-flow fuel mode (high bypass pressure). When the flow rate falls below the set
value, the AOV deactivates and the pump returns to low flow. Another possible use for this
output is the engine throttle—to increase and decrease the RPM of the pump shaft. In
applications such as these, the flow rate value in this field should be below the low flow rate
with a fully open nozzle or the output will never turn on. Another application of this field is to set
the value as a maximum flow rate at which a valve should be closed. On fuel delivery trucks,
flow valves often activate an internal switch at approximately 18 GPM (68 LPM). The value of
this field is unique to each product.
Auxiliary 2 Output
– A list box that determines how any digital output that is set to AUX 2 will
operate based on the selected product on the LCR.iQ. There are several features in the
LCR.iQ that can be performed based on the Aux settings to control external components such
as pumps, injectors, PTO, Throttle, alarms, and reset pulse.
Options:
·
Off
- Any output set to AUX 2 Calibration Mode Settings will always be off (Not active)
