• Explanations
Hi and Lo Adjustments are used to set the alarm setpoints.
A 0 – 10V DC is output at the Hi and Lo setpoint monitor
jacks across the COM jack, proportional to the setpoint 0 –
100%.
The Hi and Lo LEDs turn on when the coil for each relay is
energized.
• Examples
For setting the relay to trip above 80% of the full-scale in-
put signal, turn the Hi Adj. until you read 8.0V at the Hi
Setpoint Monitor.
