Hydraulic pump control

Hello.
I have a knee mill that has a hydraulic pump that used for hydraulic cylinder counterweight of z axis
for tools clamping and for spindle gears engaging in gearbox.
Hydraulic circuit has a pressure switch and hydraulic electrovalves for each peripheral.

How to control hydraulic pump must energize it all the time machine is on or linuxcnc
must read pressure switch of hydraulic circuit and energize-denergize the hydraulic pump
or pressure switch must enable-disable relay that drives the hydraulic pump outside linuxcnc ?

Machine.is-enabled
Should do for the output that controls the relay and pump
An input from the pressure sensor could be tied using AND2 component to the io control, sorry no exact pin as i am on the phone.
Probbly can be done by just AND2 from the normal enable and sensor on the input and machine.is-enabled to relay output.

This io control ?
linuxcnc.org/docs/html/man/man1/io.1.html

I have done this with and2 and works
but how can i give 1second delay to and2 output
so the hydraulic pump work 1s more after pressure switch triggered ?

Try oneshot or timedelay
