Pulse Generator for Mech Pump Testing

Purpose: To create means to test the MID’s compatibility to various Pulser type used in different applications. It must give the mean to test extremes that are not expected in the real world

 

Hardware: MID and an LCD display.

 

Dipswitch 1 sets the rate of the Pulse and Dipswitch 2 defines the fixed number of Pulses. If DSW2 is ALL OFF or ALL ON then it run freely at the period defined by Dipswitch1

 

	DSW1	DSW2
00	5  pulses/sec	Free running
01	10  pulses/sec	400 000
02	20  pulses/sec	600 000
03	40  pulses/sec	800 000
04	80  pulses/sec	1 000 000
05	160 pulses/sec	3 000 000
06	320  pulses/sec	5 000 000
07	640 pulses/sec	7 000 000
08	1280  pulses/sec	15 000 000

 

It would also be good to have  a GPIO to be used as an inhibit and the pulses will only start counting once it is pull hi or low.

Action : Set the Dipswitches and hit the reset and once the Start Switch is used the Pulses start. The Switch could also be used to pause the pulsing just like a Nozzle can stop pouring and continue again.

The Display gives the Settings selected (i.e. the Mode of operation) and the Shows the counting of the Pulses
