Switching module
This
module is used to generate a 0 or +5 volt signal at the pump, flow, pressure,
and forward flow cannon connector pins to be used in the logic
module. The toggle switch for pump, flow, or pressure set to ON, will
generate a +5 volt signal at each respective pin (A,B,C) and will output 0
volts at the OFF position. The forward flow start or stop buttons generate
0 volts and when they are pressed, a +5 volts signal is generated at their
respective pins (D,F). This output of the input
module (level signal) and the panic signal from the distribtion
panel enter the switching module and are passed directly to the pins H
and E of the cannon connector of this module.
