Input Configuration
You can configure the inputs, using the buttons, to accept AC, DC or low level inductive
pulses. You can also choose whether to have a pull-down or pull-up resistor (for PNP, NPN or
contact closure inputs) and whether to include de-bounce filtering, to mimimise contact
bounce effects. Each input can be configured independently. To configure the inputs, switch
the lockout switch OFF and press Set1 and Set2 buttons together for 3 seconds...

Pull-up = 47kilohm from signal input to +Excitation
Pull-down = 47kilohm from signal input to 0V
Hardware debounce with RC network.
Approx. 1/20 Second time constant.
SLOW Software debounce for very slow signals.
Set from 0.000 to 9.999 seconds. For example, if you set 5.000,
then pulses following each other by less than a 5 seconds
interval will be ignored.
You MUST disable the Slow software debounce if your input
signal is higher than 1kHz.
To enable or disable it, press the right hand 2 buttons briefly in
normal running mode, with the lockout switch off. Press OK to
select P.DBNC.X and choose P.DBNC.1 to enable or P.DBNC.0
to disable the slow software debounce.
