800.727.5646 atcdiversified.com Diversified Electronics AC-410 Series 271 Pha s e S e qu e nc e & L o s s M o n i t or The AC-410 Series are plug in Phase Sequence and Loss Monitors that protect 3 phase refrigeration equipment from adverse line conditions such as: PHASE LOSS (SINGLE PHASING): When any one phase drops to 83% or less of the adjustment setting. UNDER VOLTAGE (BROWN OUTS): When all three phase voltages drop to 90% or less of the adjustment setting. PHASE REVERSAL (IMPROPER SEQUENCE): When the wrong sequence is applied to the equipment. When any of the mentioned occurs, the internal control relay drops out and a 3 minute delay-on-break time delay begins. This delay is used to lock out the compressor, allowing time for head pressure to equalize. When the delay has completed, the relay will re-energize provided all conditions are corrected and the external control voltage is present on terminals six (6) and seven (7). A green indicator glows when all line conditions are normal and a red indicator shows when the timer is in its delay.
