Ikon AVS ltd DRS V1.00
RAW DATA
The individual channel status leds are software derived and can therefore be
configured by the configuration utility to be either on or off when a fault condition
exists.
Often to save power and enable rapid location of a fault the system is configured
to only illuminate a led if the channel is in a fault state, this is totally independent
of the network reporting of the fault. In some cases the system specification
requires the opposite with indicators always on when OK and off when a fault.
Whist both are accommodated within the DRS software it is often useful to be
able to view the actual state of inputs both to assist initial set-up and subsequent
fault finding.
Press the INPUTS button to cycle to RAW.
Now press the TEST button to cycle through the three test modes.
MODE LED FUNCTION
1T1 Each channel led shows the real (raw) state of the
input. If the opto isolator is ON (volts present or
contact grounded) the channel led is ON.
2T2 Shows which inputs are active, i.e. set-up for use
using the configuration utility. If the led is on, its in use.
3T3 Rescans the inputs and shows all current input faults.
TEST Mode
To get to test mode select RAW mode using the INPUTS button and then press
and hold TEST switch. Whilst pressing also press the INPUTS switch, then
release both switches.
Pressing the INPUTS switch without the test switch will cause the DRS to skip
the test mode and go back to normal mode.
Once in test mode all fault monitoring is disabled and the common fault relay is
on. All network reported faults are cleared.
