ABB AW400 Series Instruction Manual page 32

Digital Input: Input signals submenu the display shows
changing the status of one of the CCI by shorting the associated terminals (1-3 or 2-4) the
display shows ON below the number of the associated CCI.
Digital Output: the display will show the status of the 7 output contacts (relay):
pressing the key corresponding to displayed number (from 1 to 7) the display will change
the "0" in "1" or vice versa and the contact output status will be changed accordingly form
"OPEN" to "CLOSE": verify with an ohmmeter the status of the pertinent CCO (see
table 3).

Analog I/O Test
The Analog I/O test allows you to verify the correct value of the input and output signals.
In the analog "Input" mode, the display shows the value of the signal generated by the sensor and the
pertinent Pt100, in order to verify the correct sensor operation in an easy and fast way.
In analog output mode the instrument allows to check correct functionality of the 4–20 mA output: operating
the OUT increase and OUT decrease keys the output value indicated on display can be changed and with a
multimeter connected to the pertinent channel output [terminals 1(-), 2(+)] it can be verified that the current
output changes accordingly.

Electrical calibration
The access to this menu is protected by a password that is only known to factory personnel, because the
included parameters must never be tampered with.
The electrical calibration is only performed in the Factory at the end of manufacturing process.
