Securus
®
Electronic Moisture Monitor System
The compressor purification system may be equipped with an optional Securus II
®
Electronic Moisture
Monitor System. The Securus II
®
Electronic Moisture Monitor System warns the operator in advance of
expiration of the life of the cartridges. The Securus II
®
Transmitter receives signals concerning the con-
dition of the drying agent inside the Securus
®
cartridge from the attached sensors and supplies the
appropriate control signals whenever the preset threshold values have been reached.
6.5.2.1
Securus
®
Cartridge
The Securus
®
Cartridge is packed with a catalyst which converts carbon monoxide to carbon dioxide,
activated carbon which absorbs oil vapors, molecular sieve which absorbs oil and water and the sensor
components of the Securus II
®
Electronic Moisture Monitor System.
6.5.2.2
Securus II
®
Transmitter
See Figure 6-10. The Securus II
®
Transmitter relays the operating condition of the Securus II
®
Elec-
tronic Moisture Monitor System to the Operator Interface. The Securus II
®
issues a warning when the
Securus
®
cartridge is approaching saturation, to warn the user to prepare to change the Securus
®
car-
tridge. On a Securus
®
Warning condition, the compressor will run normally and the warning will be
shown on the Operator Interface. Once the Securus
®
cartridge has reached total saturation the Securus
II
®
Transmitter will issue an alarm condition to the Operator Interface and shut down the unit. Once the
Securus II
®
cartridge is replaced it is possible to restart the compressor. The Securus II
®
Transmitter is
removed and replaced by rotating the blue plastic Securus II
®
Transmitter approximately ½ turn. It is
not necessary to disconnect or remove the DIN Connector.
