HA40 4-Channel Controller
2 Operation
The HA40’s graphic LCD displays monitored data. The 5-button keypad and the display serve as the system’s operator interface. All HA40 configuration variables are entered using this operator interface through SETUP menus accessed by pressing Edit from either data screen. This Setup mode may be exited manually by pressing Next, or automatically when no keys are pressed for 5 minutes. Alarm relays and front panel alarm LED indicators remain active during the Setup mode. Alarm LED’s flash upon new alarms and become steady after Acknowledged by pressing the Alarm Reset key. A SECURITY menu offers a password feature to prevent tampering with HA40 parameters.
A “sign-on” screen appears briefly after power is applied that indicates what type of input / output options are configured with the unit.
2.1 Setup Menu Configuration
Variables inside the CHANNEL (see Section 2.2) and SYSTEM (see Section 2.3) menu trees allow HA40 configuration for a wide range of monitoring applications. Select the desired menu by scrolling with Up/ down arrows and then Edit to enter each menu. Figure 2-1 illustrates the menus tree for configuring Channel and System specific variables. Channel variables affect only the specific channel selected while System variables are related to features not specific to any channel.
