Installation
Filter Blocked / System Fail Signal
With this option the iQ system will output a signal to alert
the user when the extractor has failed or when the filters are
blocked.
This feature will not directly stop the extractor from running
correctly, but if fitted this feature should be terminated
correctly before power is applied to the iQ system.
Connection specification
This signal is available via the Green and White cores of the
signal cable. The iQ system will provide a volt free Open /
Closed signal that can be connected to an external interface,
beacon or warning device following the specification below.

Maximum input voltage: 24V AC

Maximum current load: 3A @ AC
OR

Maximum input voltage: 24V DC

Maximum input load: 3A @ DC
Filter Signal Configurations
There are 3 ways this signal can be configured, as detailed
below.

Combined signal (standard specification)

Separated signal

Reversed separated signal
Combined signal
With this configuration the Filter blocked & System fail
signals will be linked together to give a combined single
output.
When the filters become blocked or the iQ system develops
a fault (Refer to section
8 for Troubleshooting & Error
codes) the connection between the Green & White cables
will become “Open”
When the extraction system is running normally the
connection between the Green & White cables will become
“Closed”
Separated Signal
With this configuration the Filter blocked & System fail
signals will be separated to give 2 individual signals.
When the filters become blocked the connection between
the Green & White cables will become “Open”
If the iQ system develops a fault (Refer to section 8 for
Troubleshooting & Error codes) the connection between the
Blue & Yellow cables will become “Open”
When the extraction system is running normally the
connection between the (Green / White) & (Blue / Yellow)
cables will become “Closed”
Reversed Separated Signal
With this configuration the cable function will remain the
same as the
Separated signal option, but the signal given
will be reversed.
For blocked filters the connection between the cable cores
will be “Closed”
For iQ system faults the connection between the cable cores
will be “Closed”
For system OK the connection between the cable cores will
be “Open”
