AccuLoad IV Installation and Maintenance Manual Input and Output Details
Note: When connecting the Promass 84 (does not apply to the Promass 80 or 83 mod -
els) to an AccuLoad, it is important that the “Line Monitoring” function on the Promass
84 be disabled. This is because the pulse input circuitry of the AccuLoad requires the
input pulse “off” voltage to be less than one volt (and the “on” voltage to be greater than
5 volts). If the “Line Monitoring” on the Promass 84 is enabled, the “off” voltage of the
pulses will be greater than one volt and therefore will not be counted by the AccuLoad.
There are three jumpers on each of the frequency output submodules on the I/O board
that enable/disable the “Line Monitoring” function. The factory default is to enable “Line
Monitoring”. Follow the steps from section 6.4.2 of the Proline Promass 84 Operating
Instruction – Bulletin MN0M032 to enable/disable this function.
9.3. Meter Input Wiring Matrix
The AccuLoad totalizes volume or mass in response to pulses received at the pulse
input terminals of the A4M, A4B or A4I modules. Which pulse input connections to use
for each meter is dependent on the configuration of the AccuLoad. For product meters,
the AccuLoad automatically assigns the pulse inputs based on the products defined in
the configuration database. The number of pulse inputs required for each meter varies
based on the type of meter specified in the configuration database.
Single Channel meter - One pulse input per meter
Dual Channel meter - Two pulse inputs per meter
Dual Channel meter with Integrity - Four pulse inputs per meter
The following tables show the pulse input assignments made by the AccuLoad for each
of the possible number of product meters. Any pulse inputs which are not required for
connection of the product meters is available to be configured for use as an additive
meter or pulse densitometer.
Notes :
Differences between the AccuLoad III and AccuLoad IV connections are shown BOLD
and colored green.
Pgm – Indicates a pulse input which is programmable to function as a metered injector
or densitometer pulse input.
Example product meter naming convention:
M4A – Meter 4 channel A
M5B – Meter 5 channel B integrity – In AccuLoad IV, the valve control solenoid outputs
or metered injector solenoid outputs must be configured/landed on the same board as
the associated meter pulse input.
