The TRYCLOPS X – Purge Controller, SM Version is certified for use in Zone 1 hazardous areas. The TRYCLOPS X – Purge Controller monitors purge pressure, exhaust vent flow, controls purge time and electrical power for one, two or three purged and pressurized enclosures.
The TRYCLOPS X – Purge Controller provides local and remote objective evidence of the presence of positive minimum overpressure within the electrical equipment enclosure(s) and enclosure’s exhaust port flow. When the monitored enclosure(s) registers a proper minimum overpressure 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 indicator 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 five volumes of free space in the enclosure to be exchanged before power is automatically applied by the TRYCLOPS X – Purge Controller to the electronic equipment within the enclosure(s) the TRYCLOPS is monitoring.
After the automatic purge time has elapsed, the green LED will stop flashing and go to a continuous green state. Indicating that the monitored enclosure(s) minimum overpressure is being maintained. Up to 12.5 amps of power for 230 VAC 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 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) as long as positive minimum overpressure is maintained. If the enclosure(s) minimum overpressure should go below its setting the local LED will go from steady state green to a steady state red, power will be disconnected from the unprotected electrical 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 by the TRYCLOPS X – Purge Controller 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 exposing the electronic equipment to its surrounding atmosphere. 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 visual LED will flash red and if used, 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 if the minimum overpressure is satisfactory, the Maintenance Switch when turned to normal operation, instead of going through the purge cycle, power will remain connected to the electrical equipment.
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 local visual LED will be steady state green and blinking red.
The TRYCLOPS X – Purge Controller monitors the minimum overpressure 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 an exhaust vent for each enclosure the TRYCLOPS X – Purge Controller will be monitoring.
The TRYCLOPS X – Purge Controller, SM Version housing comes in 14 gauge 316 stainless steel. The TRYCLOPS X – Purge Controller comes with voltage options of 25 amps for 115 VAC and 12.5 amps for 230 VAC unit.
