Section 7.08
Testing the system
Start the system testing:
Turn the panel off by pressing the power button in the lower left corner. The
backlit display will turn off and the yellow led inside the power button will flash.
When a panel is turned off, all corresponding outputs will be turned off. Even
though the panel is turned off, all communication in the system continues.
Turn the panel back on. The yellow led in the power button light steady, and the
panel backlight will turn on again.
Test the various functions by pressing each button and veri fy that its intended
operation is carried out:
o
Press a button and verify that the green led starts flashing rapidly. As the
corresponding output is turned on and is verified by the output module,
the green led in the button will switch to a steady green li ght. Note that
depending on the configuration of the system, it may be that the LEDs in
a button is not intended to light up. See chapter 3.02 Buttons and LEDs
on panel for a description of the possibilities.
o
A faulty lamp or fuse will be detected by the o utput module, which in turn
relays that message to the Master CPU. As a response to this, the
buttons green and red led on the panel will flash to announce a fault.
See chapter 3.02 Buttons and LEDs on panel for a definition of what the
led statuses mean.
Always refer to the system configuration and/or termination drawings when
testing a system.
Section 7.09
Failures
If a failure is detected:
Ensure the output is terminated correctly and that the fuse and lamp is ok. Use
only fuses of correct type, refer to chapter VI Output modules.
Check whether the corresponding output module responds to the action. It does
so by flashing the Rx led ( yellow) rapidly, but it should also flash the Tx led
(yellow) about once per second or more often. Missing the Tx signal may
indicate bad communications termination, mix -up of the A and B-lines or similar.
Turn all power off and reapply power. Then start testing over again.
Network failures:
If the Activity led in the Master CPU flashes, it indicates a correct network.
If the yellow led in the Power button in the panel flashes, it may indicate a faulty
connection towards the panel. If the other modules in the system work properly
(flashing RX and TX) LEDs, the fault is somewhere between the panel and the
rest of the system. Check the com munications cable and connections. Possible
reasons may be that the A and B lines are switched, if so, reconnect and try
again.
If the Activity led in the Master CPU is constantly on, it indicates a failure
somewhere in the network. Check the above; if the yellow led in the power
