The TRYCLOPS X – Purge Controller, XP Version is certified for use in Division 1 and Zone 1 hazardous areas. The TRYCLOPS X – Purge Controller monitors minimum overpressure, exhaust vent flow, controls purge time, electrical power connecting and disconnecting for one, two or three enclosures.

The TRYCLOPS X – Purge Controller provides local and remote objective evidence of minimum overpressure within the enclosure(s) and enclosure’s exhaust port flow. When the monitored enclosure(s) reaches minimum overpressure setting above the referenced atmospheric pressure surrounding the enclosure(s) being monitored and the exhaust port(s) is registering satisfactory flow, TRYCLOPS’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 be exchanged before power is automatically connected by the TRYCLOPS X – Purge Controller to the electronic equipment within the enclosure(s) being monitoring. 

After the automatic purge time has elapsed, the green LED will stop flashing and go into a continuous green state. Indicating that the monitored enclosure(s) minimum overpressure is being maintained. Up to 25 Amps for 115 VAC or 12.5 Amps for 230 VAC of power will then be automatically connected by the TRYCLOPS X – Purge Controller, eliminating the need for an additional explosion proof enclosure with a solid-state relay.

The TRYCLOPS X – Purge Controller continuously compares the minimum overpressure inside the monitored electrical equipment enclosure(s) with respect to the atmospheric pressure surrounding the enclosure(s) preventing the ingress of flammable or combustible materials in the surrounding atmosphere from entering into the enclosure(s). If the enclosure(s) minimum overpressure should go below required setting, the local 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 will be sent to the remote point being monitored. 

Other features of the TRYCLOPS X – Purge Controller are a Maintenance Switch and Power Disconnect Bypass Switch. The Maintenance Switch is used when electrical equipment within the enclosure(s) being monitored requires electrical power for repair or maintenance. After the area surrounding the enclosure(s) has been tested and is known to be non-hazardous. The enclosure(s) can then be opened without protective minimum overpressure. The TRYCLOPS 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, will send an alarm to its point of remote monitoring. When repair or maintenance has been completed, the electronics equipment’s enclosure(s) door can then be closed and fastened. Minimum overpressure can then be restored to the enclosure(s) and the Maintenance Switch when turned to normal operation, instead of going through the purge cycle, the electrical power can remain on. 

The Power Disconnect Bypass Switch is used to override the disconnecting of power to the electrical equipment within the enclosure being monitored by the TRYCLOPS 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 TRYCLOPS 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 TRYCLOPS X – Purge Controller monitors the purge pressure and exhaust flow from up to three pressure and exhaust vent flow points, which is specified by the customer and built by the manufacture at time of purchase. The TRYCLOPS X – Purge Controller was specifically designed for use with analyzers, mounts in the general area of the enclosure(s) it will be monitoring and comes standard with a purge exhaust vent for each enclosure the TRYCLOPS X – Purge Controller will be monitoring. 

The TRYCLOPS X – Purge Controller, is explosion proof (flameproof) comes in anodized aluminum or in 316 stainless steel. The TRYCLOPS X – Purge Controller comes with voltage options of 115 VAV and 25 Amps or 230 VAC and 12.5 Amps.
