Calibrated Scaled Pulse Output
– Any output set to AUX 1 Calibration Mode Settings
will
be a calibrated pulse output that scales 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 switching 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 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 listing that determines how any digital output that is set to AUX 2 will operate on the
selected product. To control external components, there are several features in the LCR.iQ
that can be set to perform according to the Auxiliary 1 and Auxiliary 2 settings. This includes
pumps, injectors, PTO, throttle, alarms, reset pulse, among others
Options:
·
Off
– Any output set to AUX 2 Calibration Mode Settings will always be off (inactive).
·
On
– Any output set to AUX 2 Calibration Mode Settings will always be on (Active and
Sinking to ground).
