Hang Message Appears
The hang screen message will appear if an error occurs within the control software that could
effect the safe operation of the system. If the hang screen appears, write down the exact error
that is displayed on the screen and call customer support at Merrick Industries. Several types of
errors may cause the controller to reset or reboot. If this occurs, verify all parameters.
HARDWARE CALIBRATION AND TESTING
The MC³ was calibrated and tested at the factory before it was shipped. The following
procedures can affect the accuracy of the controller and should only be performed with extreme
caution.
WARNING: Always disconnect the MC³ from the feeder before attempting to test or calibrate
hardware. Failure to do so could damage the feeder or cause personal injury.
Analog Outputs
Attach a milliamp meter to the analog output to be adjusted.
In the Analog Output setup menu, select Analog Cal and set the output to 0%.
If, calibrating analog output 1, adjust the 'A01 Z' pot (R68) until the meter reads 0.0 mA. If,
calibrating analog output 2, adjust the 'A02 Z' pot (R66) until the meter read 0.0 mA.
Set the output to 100%.
If, calibrating analog output 1, adjust the 'A01 S' pot (R67) until the meter reads 20.0 mA. If,
calibrating analog output 2, adjust the 'A02 S' pot (R65) until the meter read 20.0 mA.
Set the output to 50% and verify that 10 mA is read on the meter.

Potentiometers used for adjusting analog input and outputs
Analog Inputs
Typically, a current source is not available, so the easiest way to adjust the analog input is to feed
the analog outputs back into the analog input. This is accomplished by using jumpers from the
analog output to the analog input. To calibrate the Analog Input using the 90.10.EX application,
access to the register editor, is required.
Insert a jumper wire from analog output 1 to the analog input. Insure the polarity is correct
(positive to positive, negative to negative).
In the Analog Output setup menu, select Analog Cal and set the output to 0%. Go to the
register editor and select the al_aninst1 register (this is register 385 for version 0.3A).
Adjust 'AIN Z' (R64) until the register just reads 0 (the best way to do this is approach zero
from the positive side).
Set the output to 100%. Adjust 'AIN S' (R63) until the register reads 1,000,000 counts.
Set the output to 50%. Verify that the register reads 500,000 counts.
