FIRST OUTS
7.1 Overview of First Outs
When the control circuit has a long series chain of various thermostats and switching elements, it can be difficult
to identify which element has opened the control circuit. With First Outs expansion feature it is possible to monitor
up to 15 different inputs in a series control circuit on the Flame Safeguard unit. Each input responds to a signal
voltage of between 110V to 230Vac.
The First Outs can be configured for active input state low or high. When the active input state is set to low, the
first out is triggered when the input is low, and when it is set for high, it will be triggered when the input is high.
The table below shows the functions that can be set for the first outs.
The First Out logs can be displayed by pressing in the Home screen (Figure 8.1.i), then pressing
tab button which gives information on the First Out number, trigger time and the time it was reset.
7.2 First Outs Expansion Options
The table below shows the Expansion Options used for configuring First Outs.
If first outs are enabled, they can be configured and labelled in
Commission mode and Online Changes. To tie the first outs interlock to
the MM’s safety stat, see option / parameter 145.
