Time Delays are available for the ABRIR and FECHAR operator control pushbuttons (global settings
PB8D and PB9D, respectively; settable up to 3600 cycles). These time delay settings are set to
zero from the factory (no time delay; PB8D = 0, PB9D = 0).
Figure SECTION 1: .32: Operator Controls – SEF HABILITADO through ABRIR
Detailed Operator Control Pushbutton Output
Figure SECTION 1: .31 and Figure SECTION 1: .32 list corresponding figures that detail
operator control pushbutton output and corresponding LED operation and logic operation. Note
that the pushbutton output (e.g., Relay Word bit PB1
for the TERRA HABILITADO operator
control pushbutton) corresponds number-wise to the LED setting (e.g., SEL
OGIC setting LED1
for the TERRA HABILITADO LED).
TERRA HABILITADO Operator Control Pushbutton Output
Figure SECTION 1: .33 describes the TERRA HABILITADO operator control pushbutton
output. Every time the TERRA HABILITADO operator control pushbutton is pressed
momentarily, Relay Word bit PB1 asserts to logical 1 immediately for one processing interval.
The corresponding TERRA HABILITADO LED (controlled by SEL
OGIC setting LED1) is
independent of the TERRA HABILITADO operator control pushbutton.
