i F initial repair should be limited to the exchange of X76S he alarm annunciator sun buzzer and module will indicate an alar 5 modules and verification of proper wiring of all y a leak. The X lashing will also indicate an incoming field connections. which tank has alarm should the cuter shell leak and allow ground 4.2 Annunciator Module water to seep into the tank. Troubleshooting of the annunciator module should be carried out systematically, since this module operates in conjunction with the X53-2000 Field Isolator and the intrinsically safe 7.0 SPECIFICATIONS 24 VDC power supply. In the event of a malfunction of this module, 7.1 System, Model X76S check field wiring to the input terminal connector Power: 115 VAC, 60HZ of the X53-2000 Field isolator (schematic Power Consumption: 100 VA X76-2001). Check fuse in the power supply and measure with a DC voltmeter the voltage across Operating Temperature: 32 to 165°F (0 to 75°C) the output of the power supply, confirming 21.6 Dimensions: to 30 VDC. 9 X 9.5 x 4.2 inches (22.86 x 24.13 X 10.67 cm) Replace the X53.2000 Field Isolator moduie. If Mounting: General purpose area; wall mount this does not solve the problem, the cause is in FhM1 Approved: Fife J.I. 2N4A1,AX the annunciator module, which will have to be replaced. 7.2 Annunciator Module Field Sensor: Dry contact Field Sensor Voltage: 115 VAC (suppiied 5.0 GENERAL SYSTEM DESCRIPTION by X76S) Number of inputs: One per module The Ronan Series X76S Leak Detector Monitor is FM Approved: File J.I. 2N4A1.AX . a four-point annunciator system of general-purpose design equipped with certified, intrinsically safe 7.3 Intrinsically Safe Field Sensor barriers to interface with field contacts that are Interface Module X53 located within a hazardous area as described in Number of In uts: Two per module section 1.0. The field contact, when transferring from p normally open or normally closed to its off-normal Sensors Voltage: 24 VDC, current limited state, will be visually indicated via the light-emitting Sensors: Dry contact diode and the audible buzzer will sound. The front panel-mounted pushbutton allows the operator to Output Interface to Alarm Module: Relay acknowledge the alarm, thereby changing the flashing contact; normally open/normally closed-, LED to steady-on and silencing the audible alarm. The selectable test pushbutton, if pressed, will actuate all alarm Power Consumption: 750 mW per input points to verify proper operation of the logic and the Supply Voltage: 24 VDC from IS power supply LEDs. <j> Approved: File J.I. 2N4A1.AX 7.4 Power Supply IS (Intrinsically Safe) .0 TYPICAL APPLICATION— Power Input: 115 VAC SECONDARY CONTAINMENT output Voltage: 24 VDC WANK LEAK MONITOR <�M >Approved: File J.1. 2N4A1.AX The Model X76S, used as a leak detector, 7.5 Vapor Sensor, Model HV monitors liquid levels in secondary underground tanks Detection Method: Solid-state diffusion type and/or ground wells. The system finds applications in Detectable Gases: Hydrocarbons, gasoline, gasoline and oil storage facilities to detect these leaks solvents, carbon monoxide, methane, ammonia, in time to prevent leakage or seepage of hazardous sulfur dioxide, hydrogen sulfide _ liquid into the underground water table. Detectable Range: 0.100% LEL The secondary containment tank leak monitor consists of liquid-level sensors and alarm annunciator modules, Accuracy: ±5% located in the Ronan X76S system. The liquiddevel Response Time: Less than 15 sec to 90% full sensor monitors the area between the inner and outer scale tank for possible spillage.
