Description
Set the Check Additive Tolerance Time to permit the system ample time to recover from
an Under Additized or Over Additized alarm condition. If this value is set too low, the
system will continue to go into the referenced alarm conditions until the additive error
has been reduced to within the # of injections specified by the Additized Alarm
parameters. Enter a value in units of time (seconds).
Specify the volume of Unauthorized Additive Flow that will have to accumulate before an
additive's Unauthorized Flow Alarm is activated.
 This parameter does not apply to the non-Pulser methods.
Specify the volume of additive flow that will have to accumulate before an additive's
Valve Fault Alarm is activated. The alarm occurs when an additive is authorized for use
and is flowing, but the system has not commanded additive to flow. This is the only
alarm condition that will cause the additive pump to stop.
 This parameter does not apply to the non-Pulser methods.
The intent of this parameter is to ensure, in all cases where a load is aborted, that
additive delivery will be ahead of schedule. Upon starting a load, a number of injections
will occur immediately. The number of injections that will occur immediately is
dependent on the number entered for this parameter. If a value of one is entered, a
single injection will occur as soon as Start is pressed. Throughout the remainder of the
load, a one-injection surplus will be maintained. Upon reaching completion, the volume
of additive delivered will be 100% of the specified volume, plus the volume of one
injection. If a load is terminated prematurely, it will have the proper additive volume for
the amount of product delivered, plus a volume between 0.5 to 1.0 injections. Valid
range of entries is 1.0 to 65. See
