Comp menu of the Preset and Component that has the alarm. Verify the settings of Gravity or
Density or Expansion Coefficient. Ensure that the settings are appropriate for the selected table. If
pressure correction is used, check settings in the Pressure Comp menu as well. Check the
Gravity or Density settings. Ensure that the settings are appropriate for the selected table.

4.11.5 ADDITIVE ALARM SETUP
The MultiLoad II has lost communication with the I/O board or FCM. This message indicates
that additive level functions are affected by the interrupted communication. This alarm will
automatically clear when communications are restored. Check the Diagnostic menu under
FCM Com to determine if the I/O board or FCM is communicating.
Additive Permissive. Permissives can be set to affect specific additives in multi-additive load
arms. When the Additive Permissive signal is lost, loading will stop on the load arm if the
additive is being used. The alarm will auto clear when the signal returns. The alarm message
that appears to the operator is configured via the MultiLoad Configuration Tool, at Additive
Alarms, Alarm 1.
Under Additive alarm-The load is stopped when the additive becomes under additized by the
number of injections specified by the Under Add. Alarm # Inj.
Over Additive alarm-The load is stopped when the additive becomes over additized by the
number of injections specified by the Under Add. Alarm # Inj.
Additive Valve Fault occurs when additive flow continues after the injection solenoid has been
commanded to close. When the volume specified in Valve Fault Alarm Volume has passed
the additive meter after it has been commanded shut, an alarm will be raised. The relevant
block valve and pump outputs will be dropped in an attempt to stop flow. The Pump Kill
output will be activated, if it is used. A Pump Stat alarm message will occur on other load
arms that are using the common Pump Run output. For example, if an Additive Valve Fault
occurs on a load arm’s injector that delivers Brand X additive, all other load arms in the bay
that deliver Brand X additive will display the Pump Stat alarm and will not be able to load until
corrective action is taken.
The Additive Pump Status alarm will occur in two situations. Most commonly, the alarm
occurs in conjunction with a Valve Fault alarm. If an injection valve fails to close, the relevant
pump output will be dropped in an effort to stop flow. The Pump Stat alarm will appear on all
of a bay’s load arms that make use of the common Pump Run output. For example, if a
Pump Stat alarm appears on load arm #7, it may have occurred due to an Additive Valve
Fault on another arm that is in the same bay. The Pump Stat alarm will also occur when
using the Pump Status input to monitor a pump’s pressure. When the pump loses pressure,
the Pump Status alarm will appear on all of a bay’s load arms that rely on the pump.
