208 Installation & Setup Guide
THC I/O
Analog Offset 1 - 12
The Analog Offsets 1 through 12 are used to correct for any imbalance or “zero” the incoming analog
voltage to the Analog Input Card. Analog inputs are assigned to the THC Axis and the Analog Offsets
for the appropriate THC Analog input may be adjusted here.
To calibrate the Analog Inputs, jumper the two pins specific to the input together and view the
incoming voltage at the Diagnostics Analog I/O screen. The incoming voltage should be zero. If any
voltage is displayed at the diagnostic screen, an Offset Voltage equal to the incoming voltage being
read can be entered here to “zero” the incoming voltage. Please refer to the installation instructions
later in this section for more details.
