4 dip switches (S1, S2, S3, and S5) control settings for the alarm output. The fifth dip
switch (S4) is used only to test the delay settings.
Dip switches shown in OFF
(open) position.
Failsafe/Alarm Setting: S3

Delay Settings: S1 and S2
Use the delay function to slow the response, and compensate for turbulence or false
readings.
•
Delay potentiometer P1 can be adjusted to set a delay time from 1 to 60 seconds.
•
Two separate delay settings are controlled by S1 and S2:
- for alarm activation (alarm ON)
- for alarm de-activation (alarm OFF)
•
When switches are OFF (open) the delay is enabled.
•
The position of Failsafe switch S3 determines how S1 and S2 function.
