Speed Factor
“Speed Factor” is used to calculate and set speed when the tacho function is
set to “Simulator” (see Main Menu > Advanced Setup > Tachos > Function >
Simulator).
Normally this parameter is automatically updated when a valid speed is
available from tachos. However, when in simulator mode, you may set this
parameter directly and it will then not be updated (changed).
Max Allowed Ratio Diff
This is the maximum allowable absolute value for the difference between
nominal tacho ratio and actual tacho ratio. The nominal ratio between of the
tachos is determined by the two BLT parameters “Pulses per Belt Rev 1” and
“Pulses per Belt Rev 2”, which are set during a Speed Span calibration. (see
Main Menu > Calibration > Speed Span and Main Menu > Calibration >
Numeric Data). If the difference exceeds this set amount, the Logical output
“Belt Slippage” is turned on. The units of this parameter are percent (%).
Zero Spd Distance
This parameter corresponds to how much belt travel to allow without a pulse
from the “Zero Speed” tacho (see Main Menu > Advanced Setup > Tachos >
Function). If a pulse from the tacho set as the “Zero Speed” tacho is not
received by the time the belt has moved this distance, then the Logical output
“Belt Slippage” is turned on. The units of this parameter are length (i.e. ft or m).
Process Control

PID
Selection of this menu item shows you the list of parameters that are the settings
for conventional PID (Proportional plus Integral plus Derivative) control and their
current value. PID is the control action that enables the Genetix to maintain the
desired setpoint, by constantly striving to minimize the deviation between the
