I am bench testing my global link 520, with the objective of using it to count bilge pump cycles. Initially I am shorting digital input 1 and 2 to ground to simulate a relay closing for the bilge pump (input 1) and another relay closing for the high water alarm (input 2).
Digital input 2 is creating an alarm email as expected, but the counter on digital 1 is incrementing by 10-20 each time I short the wire to gnd. I would expect it to increment by 1. I have tried all the possible settings: pulse counter, bilge pump, etc.
What am I missing here? Shouldn't the digital input be incrementing by 1?
