10.2.5. SECURUS indicator unit Function 46 Operator’s Manual The SECURUS indicator unit receives signals concerning the condition of the drying agentinside the filter cartridge from the attached sensors and furnishes appropriate control signals whenever the preset threshold values have been reached. The annular sensor inside the filter cartridge head senses changes in capacitance caused by the saturation within the surrounding drying agent. The signal path from the sensor leads through a spring pin contact, which forms the connection between cartridge and filter head, to the pressure resistant bushing in the filter head and continues through the centre conductor of the coaxial cable to the indicator unit. The signal return is effected through the cable shield to the cartridge housing. The four operating conditions of the SECURUS system are reported by three relays (normally open contacts). Simultaneously with the closing of the relay contacts, built--in luminescent diodes illuminate: 1. Continuous green: .......... Unit in operation 2. Flashing yellow: ............. Cartridge change pre -warning 3. Flashing red: ................ Compressor shut -down because cartridge is used up 4. Continuous red: ............. Compressor shut -down because of missing cartridge or cable failure If the yellow diode is flashing, the green diode will continue to illuminate because unit is still operational with the yellow light on. If no lamp is on, which means that no relay contact is closed, the SECURUS indicator unit receives no operating voltage or the electronics within the unit have failed. After applying operating voltage to the unit it will take about 0.5 seconds to close the respective relay contactand to light the applicable diode. During this time the status of the cartridge is being checked.
Operator’s Manual 10.2.6. Air flow diagram Fig. 31 shows the air path through the SECURUS filter system. The filter assembly with the pressure resistant bushing for the filter cartridge with sensor is installed as the last filter before the pressure maintaining/non--return valve.
