VYPER/MOD D VARIABLE SPEED DRIVE SCREEN

FIGURE 31 - VYPER/MOD D VARIABLE SPEED DRIVE SCREEN

OVERVIEW
This screen displays information pertaining to a Vyper/
Mod D Variable Speed Drive (VSD).
DISPLAY ONLY
PRV Position
Displays the Pre-rotation Vane position as a value be-
tween 0 and 100%.
Motor Run (LED)
Indicates whether the digital output from the controls is
commanding the motor to RUN.
% Full Load Amps
Displays the motor current as a percentage of the Full
Load Amps (FLA) value.
Current Limit Setpoint
Displays the current limit value in use. This value could
come from a 0 to 20mA, 4 to 20mA, 0 to 10VDC or 2
to 10VDC input in Analog Remote mode, PWM signal
in Digital Remote mode, E-Link Gateway interface in
ISN mode, or a locally programmed value.
