6. e Start up and Preventive Maintenance A preventative inspection and cleaning of components should be completed whenever the analyzer is restarted after a long downtime gt 2 weeks or at least annually if the analyzer is operating constantly Likewise the analyzer has several mechanical components that will wear out over time To prevent future problems these components should be checked and or replaced periodically This is most easily accomplished at the time of initial restart e Troubleshooting Occasionally problems will occur with the analyzer readings or chemical dosing These problems are most often simple to correct The troubleshooting section provides instructions to help correct problems easily 6 1 Monitoring HYDROGUARD Alarms HYDROGUARD issues alarms when it detects chemical levels that are above or below the allowed range Every alarm is automatically displayed in the LCD status display and logged in the data logger Most deviations in chemical levels however are automatically corrected Thus the internal alarms do not immediately activate an external alarm A delay mechanism prevents false alarms from minor deviations that were automatically corrected The external alarm is only activated after an internal alarm has been continuously active for a certain period of time as defined by the operator The Alarm Delay command in the Operator Menu sets the number of seconds HYDROGUARD waits before closing Relay 5 the relay
