Control with Digital Inputs

The user can run the V-Green 165 at the programmed STEP 1, STEP 2,
STEP 3, or OVERRIDE speeds by utilizing the four digital inputs. STEP
1, STEP 2, STEP 3, or OVERRIDE are equivalent to Digital Input 1, 2, 3
or 4 respectively.
NOTE: The controller is rated to accept digital inputs of 18V-30V AC
(24V AC+/- 20%) and 9-30V DC (12/24V DC +/- 20%).
NOTE: The V-Green 165 will detect either a 50/60Hz for AC input or an
active low signal for DC digital inputs.
The items below describe the functionality of the digital inputs:
1. If the user provides any one of the 4 digital inputs, then the
corresponding ACTIVE STEP LED will blink every one (1) second.
The SPEED LED and corresponding bar graph LED will be illumi-
nated to indicate the Digital Input is functioning properly.
2. The START LED will be OFF when a digital input is present.
Access to these terminals is in close proximity to the mains connectors which carry line
voltage capable of causing personal injury or damaging the equipment if contact is made.
Power should be turned off when accessing this area.
NOTE: A generic wiring diagram is provided in figure 7 for connecting
the V-Green 165 to a "System Level Controller". This concept can be
applied to a solar system or any other type of control system.
NOTE: There is no schedule for digital inputs. The timing for each
speed is controlled directly by the digital inputs.
NOTE: The digital inputs have the highest priority amongst all the inputs
(i.e., keypad, serial, or digital). Therefore the serial commands as well as
the User Interface inputs will be ignored when a digital input is present.
NOTE: If more than one digital input (switch) is present, then the V-
Green 165 will give priority to the highest number digital input. There-
fore OVERRIDE has highest priority followed by STEP 3, then STEP 2,
then STEP 1.
