Overview
The "RUN" mode permits the operator to select the
recipe, the preset volume and start the preset volume
or to observe the dynamic variables such as flow
rate, temperature, volume correction factors, trans-
action totals and non-resettable totals.
Product delivery is controlled by several program
code entries. Functions such as: first high flow rate,
second high flow rate, low flow start, first and second
trip points will be automatically controlled and moni-
tored per their program entries. Safety and volume
accuracy functions such as excess high flow, low
flow, overrun and temperature probe failure are also
monitored per their program values. If at any time an
alarm occurs while in the Ready State or the Run
Mode, AccuLoad II will attempt to shut down the flow
and a message indicating an alarm condition will al-
ternate with the current display.
When the delivery is completed, the left-hand display
will read:
Preset Completed
Depending on how AccuLoad II is programmed, the
transactions for the preset position used could be
ended by removing the ticket from the ticket printer,
pressing the “PRINT” button or by a communication
command. If the “STOP” button for the preset posi-
tion is pressed during flow, and if the STOP/START
delay is programmed, the left-hand display will read:
100 Restart in 5
where 100 is the volume of product that has been
delivered and the 5 is the number of seconds (that
have been programmed in code 209 of the Systems
Directory) before the operator can restart the batch.
Once the time-out has been reached, the left-hand
display will then read:
Press Start to Continue
The operator can then press "START" and continue
the batch. If program code 209 is programmed to
disable the time-out, the display will read:
Press Start to Continue
as soon as the operator presses "STOP". Then it will
alternate with the preset display.
Remote Start/Stop
Two permissive sense contacts can be programmed
in AccuLoad II that can be used for Remote
Start/Remote Stop operations (codes 807 and 811).
To use these permissive sense contacts as Remote
Start or Remote Stop, hardware jumpers must be in-
stalled on the keypad and computer boards in the
proper position for correct operation. When AC power
is applied to the contacts, AccuLoad II will respond
as though the “START” or “STOP” button has been
pressed. (See the Installation Manual MN06064 for
jumper positioning).
Quad OPV
The optional Quad OPV is a hardware option that
provides two additional DC outputs. This output can
either be used as a relay output or a pulse output,
remote counter, etc. If used as a pulse output, the
pulse rates and type of pulses are programmable in
the 300 subdirectory of the Products Directory. The
pulse rates are programmable between 000.1 units
per pulse and 999.9 units per pulse with a maximum
frequency of 500 Hz. The programmable options for
the type of pulses are Raw, Gross, GST, Net and
Mass.
Additive Monitoring
The additive injector feedback option provides the
AccuLoad II with the capability to monitor the additive
products that are being injected. The AccuLoad II
monitors the injector feedback switches for a change
of state and counts the errors and alarms if no
change is detected within a programmable period.
Note: See program codes 841 through 866 of the Systems Directory
for programming the Additive Feedback option.
