Note: Event (Auxiliary) Outputs ON or OFF for Ch-1 and Ch-2
Monitoring and entry requires the decimal equivalent of the binary number totaling the states of the
events for each channel.
Each of the event outputs has a “1” state for ON or a “0” state for OFF.
If DIP SW-1 is ON, there are 4 events per channel, 8 total.
If DIP SW-1 is OFF, Event #4 for each channel is an alarm, and thus there are only 3 events per
channel, 6 total.
Event # 4 (or 3) holds the most significant digit position in the binary number denoting the states of
the events.
To find the decimal equivalent, add
the integers representing the ON state for each event:
(Event 4=8, Event 3=4, Event 2=2, Event 1=1)
0000=0 0001 =l 0010=2 0011=3
0100=4 0101=5 0110=6 0111-7
1000-8 1001=9 1010=10 1011 = 11
1100=12 1101=13 1110=14 1111 = 15
000=0 001=1 010=2 011=3
100=4 101=5 110=6 111=7
The individual events are programmed to a “1” or “0” state when a step is entered; they remain in
the same state until a different step changes them.
