loop circuit has
failed
Fail safe mode
¨
In this mode if there is a loop communication failure lasting over 1 minute duration, then all
the outputs of the unit are activated (switched On). The outputs deactivate on restoration of loop
communication. On pressing the reset button on the PCB you can restore outputs to their
normal state.
¨
If there are three communication failures over 10 minutes duration the outputs will be latched
On, in this case the unit must be powered down and powered up again to unlatch and restore the
unit for normal operation.
