4.1 Start up View (HOME Display)

Note: The displays shown above are examples. The actual display, which includes the analogue values and alarm states, depends upon the process conditions to which the controller is connected.

For example, an alarm condition might be shown on switch on by the beacon ALM and the message AL– flashing. This could be because the alarm setpoint has not yet been set up correctly. The alarm can be acknowledged as described in section 4.3.4 or the alarm setpoint changed as described in section 4.3.2.

ALM	Alarm active (Red)

3	Lit when output 3 is ON (808 & 804 only)
4	Lit when output 4 is ON (typically alarm)
SPX	Alternative setpoint in use (SP2)
REM	Digital communications active (flashing)
