Table of alarms and signals.
When an alarm is activated, the display shows the corresponding message that flashes
alternating with the temperature; if fi tted and enabled, the buzzer and the alarm relay are also
activated.
All the alarms have automatic reset (that is, they stop when the causes are no longer present),
except for alarm ‘CHt’ which has manual reset (instrument on/off using the UP button or by
disconnecting the power supply).
Pressing the SET button mutes the buzzer, while the code displayed and the alarm relay only
go off when the causes of the alarm have been resolved.
The alarm codes are shown in the table below:
