Analog Input Diagnostics
Note: The appearance of the View screen depends on the type of Analog Input Card that
is 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. 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 voltages
coming into the analog card. Analog Inputs 1 and 2 are used for THC 1 and 2. Analog
inputs 3 and 4 are used for optional external speed pots.
