The CYCLOPS X – Purge Controller, XP Version is certified for use in Division 1 and Zone 1 hazardous areas, which monitors minimum overpressure, exhaust vent flow, controls purge time, electrical power connecting and disconnecting.
The CYCLOPS X – Purge Controller provides local and remote objective evidence of the presence of positive minimum overpressure within the equipment enclosure and enclosure’s exhaust port flow. When the monitored enclosure reaches required minimum overpressure above the referenced atmospheric pressure surrounding the enclosure being monitored and the exhaust port is registering satisfactory flow, CYCLOPS’s local green LED will begin flashing. An automatic purge time may then begin. The purge time can be from one to ninety-nine minutes, which is set by the customer to allow at least four for Division or five for Zone, enclosure volumes to be exchanged before power is automatically connected by the CYCLOPS X – Purge Controller to the electronic equipment within the enclosure the CYCLOPS is monitoring.
After the automatic purge time has elapsed, the green LED will stop flashing and go continuous. Indicating that the monitored enclosure minimum overpressure is being maintained. Up to 25 Amps for 115VAC or 12.5 Amps for 230VAC of power will then be automatically connected by the CYCLOPS X – Purge Controller, eliminating the need for an additional explosion proof enclosure with a solid-state relay.
The CYCLOPS X – Purge Controller continuously compares the required minimum overpressure inside the monitored enclosure with respect to the atmospheric pressure surrounding the enclosure preventing the ingress of flammable or combustible materials from entering into the enclosure as long as proper minimum overpressure is maintained. If the minimum overpressure should go below its required setting, the LED will go from steady state green to a steady state red, power will be disconnected from the unprotected equipment and if used an alarm for either situation, will be sent to the remote point being monitored.
Other features of the CYCLOPS X – Purge Controller are a Maintenance Switch and Power Disconnect BypassSwitch. The Maintenance Switch is used when electrical equipment within the enclosure being monitored by the CYCLOPS X – Purge Controller requires electrical power for repair or maintenance. After the area surrounding the enclosure has been tested and is known to be non-hazardous. The enclosure can then be opened without minimum overpressure. The CYCLOPS X – Purge Controller’s Maintenance Switch can then be put in maintenance mode and power will then be applied to the electrical equipment for repair or maintenance. During this time the local LED will flash red and if used, an alarm will be sent to its point of remote monitoring. When repair or maintenance has been completed. The electronics equipment’s enclosure door can then be closed and fastened. Minimum overpressure can then be restored to the enclosure the Maintenance Switch when turned to normal operation, instead of going through the purge cycle, the electrical power will remain connected.
The Power Disconnect Bypass Switch is used to override the disconnecting of power to the electrical equipment within the enclosure being monitored by the CYCLOPS X – Purge Controller for installations where immediate loss of power would result in a more hazardous condition. Power to the electrical equipment within the enclosure being monitored by the CYCLOPS X – Purge Controller shall be permitted to be continued for a short period of time if alarms are provided at a constantly attended location. During this time the LED will be a steady state green and blink red.
The enclosure exhaust vent is an integrated part of the CYCLOPS’s casing. The CYCLOPS X – Purge Controller mounts directly to the enclosure being monitored. This means no additional holes, sheet metal, or tubing for plumbing is required for installation. The CYCLOPS X – Purge Controller comes in anodized aluminum or 316 stainless steel, with voltage options of 115 VAC at 25 Amps or 230 VAC at 12.5 Amps.
