Questions and answers
How to configure DTS SMX output to read per unit per day
The DTS SMX output can be configured using DTS Config software. To configure output for per unit per day readings:
1. Use digital outputs (potential-free solid state N.O. relays) for energy pulses.
2. Channel 3 (marked “PULSE OUT”) provides kWh pulse output.
3. Set pulse rate using Switches 2.1 and 2.2 as described in Section 5.3.2.
4. Use DTS Config to define pulse output based on energy usage.
5. Collect and sum pulses over a 24-hour period to calculate per unit per day.
Direct setting for "per unit per day" output is not mentioned, so data must be processed externally based on pulse counts.
