The CYCLOPS X - Purge Controller is certified for use in Division 1 and / or Zone 1 hazardous areas, which monitors purge pressure, exhaust vent flow, and controls electrical power and pre dilution purge time of one (1) pressurized enclosure.
The CYCLOPS X - Purge Controller provides local and remote objective evidence of the presence of positive purge pressure within the electrical equipment enclosure and enclosure's exhaust port flow. When the monitored enclosure registers a pressure of at least 0.30 inches of water column (0.75mbar) above the referenced atmospheric pressure surrounding the enclosure being monitored and the exhaust port is registering satisfactory flow, CYCLOPS's local green LED indicator will begin flashing. An automatic dilution purge controlled time delay may then begin. The time delay can be set from one (1) to ninety nine (99) minutes, which is set by the customer to allow at least five (5) times the volume of free space in the enclosure to be exchanged before power is automatically applied by the CYCLOPS X - Purge Controller to the electronic equipment within the enclosure the CYCLOPS is monitoring.
After the automatic dilution purge time has elapsed, the local green LED indicator will stop flashing and go into a continuous green state. Indicating that the monitored enclosure pressure is being maintained above 0.30 inches of water column (0.75mbar) and enclosure exhaust port is registering satisfactory flow. Up to 12.5 Amps of power will then be automatically applied by the CYCLOPS X - Purge Controller, eliminating the need for an additional explosion proof enclosure with a solid-state relay.
