VIII. SYSTEM TROUBLE SHOOTINGA. The Trouble-Shooting Chart and associated electrical and plumbing schematics will enable plant engineers todiagnose and trouble-shoot most system malfunctions. Several additional factors may also help.1. If the main water supply to the unit must be temporarily disconnected, make sure to TURN OFF the MainDisconnect Switch to the unit.2. If the salt or water feed rate has been radically changed, then contents of the holding tank must also beadjusted, i.e., if the water rate has been set too low or the salt feed set too high, then the contents of the tank mustbe diluted. The opposite is true if the reverse has occurred.3. If less than 230/460 VAC 3 Phase 50/60 HZ is supplied to the unit, the voltage to the cells will be low byapproximately 0.5 volt D.C. As the optimum operating voltage is 6.0 to 6.5 volts D.C. a decrease in cell currentwill be evidenced by a drop in the D. C. Ammeter. If the system is generating sufficient Hypochlorite in thiscondition no adjustment is required. If the unit is required to operate at maximum capacity, however, change thetaps on the transformers as shown in BI-652-D Wiring Diagram, or increase the salt feed.4. The Cell D.C. Voltage consists of full wave rectified D.C. If it is necessary to check the cell voltage, use a D.C.Voltmeter with a 1 to 10 or 1 to 15 volt D.C. scale.22
