Ballast Monitor I.M. 1. Introduction The Detcon Ballast Monitor is a sequential 4 channel gas monitor unit. The sensor assembly, discussed in the attached sensor manual, is specified at time of order as to gas and range of detection and other options. The NEMA 7X rating is by definition explosion proof and therefore is suitable for outdoor location in electrically hazardous environments. The enclosure houses a 24 VDC power supply, flow pump and flow fault detection circuit.
Ballast Monitor I.M. 2. Install four lengths of tubing from the desired sample points to the appropriate ‘Sample Port’ inlet on the Ballast Monitor. There are four input ‘Sample’ ports that should be connected to for separate sample points. Note: When detecting for NH3, CL2, CLO2, or HCL care must be taken to use a minimum amount of stainless steel tubing and connections because stainless steel readily absorbs these gasses and will cause significant error in the detection process.
Ballast Monitor I.M. Figure 3 Flow Fault PCA Adjusting the Flow Fault PCA trip point: 1. Completely close the Bypass Rotameter to ensure that it does not affect the reading of the Flow Rotameter. 2. Use the Sample Flow Rotameter to set the air flow at the point where the fault condition should activate. 3. Turn the flow fault adjust potentiometer (PT1 in Figure 3) clockwise until the flow fault LED (D2) illuminates and the associated relays fire.
Ballast Monitor I.M. 4. Calibration The Ballast Monitor and the attached sensor are calibrated prior to shipment and should require minimal adjustment at the time of installation. However, it is recommended that a complete calibration is performed on a periodic basis to assure optimum unit performance. Refer to the sensor’s instruction manual for gas type, range, and sensor specific calibration instructions.
