The Digital Remote GUARDIAN Ultraviolet Monitor is intended for use in locations away from the water purifier it is monitoring. In all other respects, the remote operates in the same manner as the standard Digital GUARDIAN Ultraviolet Monitor. The ultraviolet sensor, instead of being mounted inside the monitor, is mounted in the sturdy, waterproof main sensor body, which when coupled with the lower sensor body becomes the remote sensor probe. A cable connects the remote sensor probe to a socket located on the back of the monitor. The standard cable length, supplied with the digital remote monitor, is 50-feet. The cable length may be extended. Available for use with all SANITRON® and Mighty-Pure® models.
The GUARDIAN Ultraviolet Monitor visually indicates the level of germicidal ultraviolet energy that penetrates the quartz sleeve and water within the water purifier. The use of an ultraviolet monitor is recommended by the United States Public Health Service in “Criteria for the Acceptability of an Ultraviolet Disinfection Unit.”
Fits Sanitron models: S14A, S17A, S23A, S37C, S50C
Fits MightyPure models: MP16A, MP22A, MP36C, MP49C
The GUARDIAN Ultraviolet Monitor will detect reduction of ultraviolet levels due to:
- Fouling or deposits on the quartz sleeve.
- Poor ultraviolet transmission through the water. Color, turbidity, and organic or other impurities in the water can reduce or interfere with the transmission of ultraviolet rays.
- Lamp outage, component or power failure.
- Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use - lamp replacement is recommended once each year.
All GUARDIAN Ultraviolet Monitors provide output sockets for the operation of an optional
solenoid valve or time delay/solenoid valve combination and optional audio alarm.
The GUARDIAN Ultraviolet Monitor is mounted directly onto the water purifier. The sensor probe is installed into the sight port fitting of the water purifier. The collar on the bottom of the GUARDIAN Ultraviolet Monitor is secured over the sensor probe. Older model water purifiers may require a reducing bushing to properly mount the newer sensor probes. If unsure whether the reducing bushing is required, contact the factory.
The Digital GUARDIAN Ultraviolet Monitor can provide a programmed 2-minute time delay for solenoid valve operation. This feature is disabled when shipped. For the instructions to enable the time delay feature, contact the factory.
The Digital GUARDIAN Ultraviolet Monitor provides outputs for remote monitoring of the water purifier’s operation.
• 4-20mA Output: Provides current for remote display of ultraviolet intensity.
• Dry Contacts: Provides contacts for remote indication of ultraviolet trip levels.
• 12v DC Output: Provides power for a low-voltage audio alarm.
A modular cable and modular jack adaptor are required to interconnect between the GUARDIAN Ultraviolet Monitor and the remote monitoring devices. The modular cable and modular jack adaptor are not supplied and can be obtained from the factory, contact the factory with specifi c requirements.
