The CYCLOPS Y&Z - Purge
Indicator for use in Division 2 and / or Zone 2 hazardous areas, which monitors purge pressure in one (1) pressurized enclosure. Type "Z" purging reduces the
classification within a protected enclosure from Division 2 and / or Zone 2 to nonhazardous. If all equipment in the protected enclosure is approved for Division 2
and / or Zone 2 locations, the CYCLOPS Y&Z-Purge Indicator can be used for type "Y" purging. Type "Y" purging reduces the classification within the protected
enclosure from Division 1 and / or Zone 1 to Division 2 and / or Zone 2.
In both the "Z" & "Y" type purging; failure to maintain pressure within the protected enclosure is detected locally by a green LED visual indicator and for remote
monitoring a dry contact is standard on the CYCLOPS Y&Z-Purge Indicator. The dilution purge time is a manual operation and once the enclosure has been purged of
ignitable or flammable concentrations, only positive pressure is required to be maintained within the enclosure and it is not necessary to remove power from the
protected equipment upon the loss of purge pressure.
The enclosure exhaust vent is an integrated part of the CYCLOPS Y&Z-Purge Indicator casing, which comes in either anodized aluminum or in 316 stainless steel,
with voltage options of 12 or 24 VDC and 115 or 230 VAC. The CYCLOPS Y&Z-Purge Indicator mounts directly to the enclosure being purged. This means no additional
holes, sheet metal, or plumbing is required for installation of the CYCLOPS Y&Z-Purge Indicator.
The CYCLOPS Y&Z-Purge Indicator provides an objective evidence of the presence of adequate positive purge pressure above 0.20 inches of water column (0.50mbar)
from a single pressure point within electrical equipment enclosure. When the monitored enclosure registers a pressure of at least 0.20 inches water column (0.50mbar)
above the reference atmospheric pressure surrounding the enclosure, CYCLOPS's green LED indicator will light up. A manually controlled time delay may then begin.
Typically, a minimum time delay is specified to ensure that at least five (5) times the volume of free space in the enclosure is exchanged before power is manually
applied to the electrical equipment being monitored by the CYCLOPS Y&Z-Purge Indicator.
After the manual time delay has elapsed and the CYCLOPS's green LED indicator light is still illuminated, showing that the monitored enclosure pressure is being
maintained above 0.20 inches of water column (0.50mbar), power may be manually applied to the electrical equipment within the protected purged enclosure. For
further information refer to Sales Brochure, or Users Manual.
