The System and Control menu allows you to configure the Liqui-tect panel—setting up inputs and
outputs and system features such as date and time. This menu also provides a vehicle for mapping
points, clearing latched alarms and deleting records from the Liqui-tect panel’s alarm and trend logs.
The arrows
↑↓ are used to scroll through the menu. The Enter ↵ key is used to select the menu item
and enter new information. Table 7 shows characters that may be entered in labels and values.
The System and Control options require a password to prevent unauthorized users from making
changes to the system.
This section presents step-by-step instructions for each of the following:
• Login - enter the password
• Setup System - configure the Liqui-tect panel, system features
• Reset Latched Alarm - clear and reset any latched alarms
• Clear Alarm History - delete all records from the Alarm History Log
• Clear Zone Trend - delete all records from the Zone Trend Log
