Analog Input Diagnostics
Note: View screen may vary depending on the Analog Input Card installed.
Inputs
The Analog Input Card required to operate the optional Joy Stick and Speed Pots is equipped with six
low voltage Inputs that are optically isolated and can operate at 24 – 120 VAC/DC. The first four
inputs are used for the optional Joystick feature and inputs five and six are used to support THC One
and THC Two Nozzle Contact Sense respectively. The Input Logic for these inputs is normally open.
Analog Inputs
The Analog Input values shown in the upper right hand of the screen are the actual voltages coming
into the analog card. Analog Inputs one and two are used for THC One and Two. Analog inputs
three and four are used for optional external speed pot referencing.
