Temperature ControlleriB6 / iB124.0 Alarms & Alarm Indication

4.1 Types of Alarms

The iB6 and iB12 Temperature Controllers support high and low deviation alarms, configurable

separately for each zone (see subsection 5.6). The unit also recognises process problems (such as

loop break, reversed and open sensors, and process temperature exceeding configured safety limit)

and problems with its own operation.

4.2 Alarm Indication

When a zone is in alarm:

• its red alarm LED flashes rapidly (Slow flashes mean an alarm was detected, but the problem

does not affect operation now. For example, a zones red alarm LED flashes slowly if an open

thermocouple is detected, but the zone is operating in Manual mode (in which no sensor value is

used by the controller to calculate the output)

• the alarm relay closes

• a code for the type of alarm alternates with display of the setpoint (Normal mode or other closed-

loop mode such as closed-loop boost) or output percentage (Manual mode or other open-loop

mode such as open-loop standby); and

• unit beeps until the alarm condition is cleared or the zone is put in Idle mode or the alarm is

silenced (refer to Section 4.3 below).

4.3 Silencing Alarm Beep

You can temporarily silence the alarm beep by pressing the alarm silence button . Beeping will be

silenced for the configured number of seconds. (The default is 120 seconds.)

4.4 External Indication

An output on the back of the controller allows external devices (such as horns or lights) to be

connected to the controller for alarm annunciation. For more information about this feature, see the

diagrams shipped with the controller.

This alarm output is not affected when the alarm silence button on the front of the controller is

pressed.
