AccuLoad III-S and N4 Hardware Worksheet
Issue/Rev. 0.2 (9/07) Bulletin AB06050

This worksheet is being provided to ensure that the AccuLoad III-S or N4 hardware contains enough I/O for the
application. This sheet should be filled out for every application. The AccuLoad III-S and N4 hardware is capable
of controlling one or two arms in straight arm loading applications, and up to six products per arm in sequential
blending and/or ratio blending applications. When configured for ratio blending, the AccuLoad III-S and N4 are
capable of controlling three product streams (6 product streams: Rev 10.08 and above). Contact your local Smith
representative if you have any questions about this worksheet.

Note: AICB boards can be added to provide additional pulse inputs for additive meters. The AICB board adds 10 additional additive meter in-
puts. For the AccuLoad III-N4 hardware, the AICB board must be mounted in a remote housing. . Flow Controlled Additives must be wired to
the PIB board.

the AICB board is required for additional metered additives, that all additives be connected to the AICB board.
2 Upstream and downstream solenoids should be programmed and wired on EAAI AccuLoad board.

AccuLoad III-S Model Number (Refer to Specification Sheet SS06036)

ALIII-S-XP - - A XXXXX - X

ALX1 Digit 1: # of RTDs A – AICB Board

ALX2 Digit 2: # of 4-20 mA inputs
Digit 3: # of 4-20 mA outputs
Digit 4: # of 1-5 Vdc inputs
Digit 5: # of 1-5 Vdc outputs

The optional AICB can be mounted inside the AccuLoadIII® or in a remote enclosure. It is recommended that it be
mounted at or near the additive injector panel to save on wiring costs. All that is needed back to the AccuLoad III
is +24 Vdc power and a communication cable. Consideration should be given to mounting the AICB in the remote
housing any time the additive panel is a considerable distance away from the AccuLoad. The cost of running +24
Vdc power and one communication wire versus the remote housing and all the additive wiring should be consid-
ered.

AccuLoad III-N4 Model Number (Refer to Specification Sheet SS06041)

ALIII-N4 - - - - 0 - A XXXXX -

ALX1 0 0 0 Digit 1: # of RTDs 0 – 10 (fuse holders)

ALX2 1* 1** 1*** Digit 2: # of 4-20 mA inputs
2 Digit 3: # of 4-20 mA outputs
Digit 4: # of 1-5 Vdc inputs
Digit 5: # of 1-5 Vdc outputs

* Stop Button. 0 = None; 1 = 120/230 Volts AC

** Indicator Lights. 0 = None; 1 = 120 Volts AC

***Hardware Options. 0 = None; 1 = Card Reader; 2 = Captive Card Reader

The AccuLoad III-N4 hardware can be used in conjunction with the AICB board, but these additional boards must
be mounted in remote housing and +24 Vdc power and a communication wire run between the AccuLoad and the
remote boards.

If your application exceeds the number of I/O points available on the AccuLoad III-S or N4 hardware, refer to the
worksheet for the AccuLoad III-Q hardware (AB06049) or the AccuLoad III-SA hardware (AB06068). It may be a
better fit for your application.
