After you have finished making the wiring
connections, install the terminal block on the
module, making sure the terminal block is
tightly seated. Be sure to tighten the retaining
screws. Also verify that the loose terminal block
LED is off when the system power is applied. If
the TB LED is on, then the terminal block is not
connected properly.
Once you have the field wiring connected, you're ready to write the control program.

Response delay switch is set with Switch 2,
positions 5–8 on rear of the module. This is only
for points X0 – X3. Points X4 – X7 are fixed at the
fastest response.
