Figure 4-55. Analog Inputs Calibrate Screen
The adjustments for calibrate will be available if the control is in operator level or greater.
Speed Input Screen
The purpose of this screen is to configure the Speed inputs of the control.
Access this screen trough the analog inputs screen, pressing the soft key “Speed Signal 1” or “Speed
Signal 2”.
This manual will explain the speed signal 1, but the speed signal 2 has the same parameters.
Figure 4-56. Speed Signal 1 Screen
There are some monitored values at the left top of the screen. They are just for monitor purpose, they are
the speed value for this input (in rpm), the phase difference (for both channels the phase difference
output will always indicate the number of degrees from speed signal #1 to speed signal #2), the amplitude
of the signal (in Vrms) and if the speed sensed is below the minimum speed..
There are three more displays at the left bottom of the screen. Two of them are for monitor purpose only
and they are described below.
Prox Signal Max (Volts): the maximum voltage sensed on the proximity probe speed input. This output
is an average of ten samples with the minimum and maximum samples discarded. This output will be zero
if the PROB_TYPE is not “Proximity Probe”.
