INSTRUMENTATION WITH AUDIBLE ALARM
Programming for Honeywell Instruments
A sample program is entered into the instrument memory at the factory to demonstrate how the
audible alarm works. The sample program consists of 1 minute ramps and soaks. At the end of a soak
segment, there is a 1 minute ramp used for the alarm segment. The audible alarm is a programmed
“event” alarm. This means that at the beginning of the chosen alarm segment, the relay for the bell will
close, and the bell will be energized. At the end of the segment, the relay will open and the bell will be
de-engergized. One minute is the shortest time that can be programmed, so a toggle switch is provided
to turn the bell off. The operator must remember to turn the toggle switch back on so that the alarm will
ring again in the next program. Power to the bell is indicated by a light below the toggle switch.
To change the alarm segment number, press the set up button until alarms appears in the lower
display, then press the function button. A1S1VAL will appear in the lower display. A number is entered.
This is the segment that the alarm contact is energized at the beginning of. Press function again and
A1S2VAL will appear. This is the segment that the alarm contact is de-energized at the end of.
A segment could probably be saved by changing the alarm values. To do this, change A1S1VAL
to the segment number needed for the alarm to sound on at the end. Then change A1S1HL to end.
This would allow the alarm to sound at the end of the desired segment, then it would have to be turned
off by the toggle switch. Upon a new cycle start up, the toggle switch would have to be turned back on.
