Relay 1 and 2 are used to set each alarm.
These correspond with the alarm output
connections located at the bottom of the
instrument.
If Relay 1 is selected for Main Alarm only,
Relay 2 can be selected for Pre Alarm.
The ratings for volt free contact are 0.5A at
125Vac and 1A at 24Vdc
The socket is shown here from outside the
unit.
2 matching plugs are provided with each
F8100.
The action of the contacts can be adjusted in
the software from active to passive by
selecting the Inverse tick box.
By selecting the Sounder, an audible tone will
be emitted from the instrument in the event
of any of the readings exceeding their
minimum and maximum value.
This is an optional, factory fitted feature
which allows a beacon to be fitted on the unit
itself.
If Power Fail is selected, then in the event of a
failure of the mains power supply, it will
activate the alarm.
To function correctly the F8100 requires a
minimum 2 barg supply pressure (10 barg
maximum). In the event the supply pressure
falls below 2 barg, the unit will activate its
alarm. For situations where the drop in
pressure may only be temporary a delay can
be added (in seconds) before the alarm is
activated.
