Powering up the system
Attention:
When you think you have the system completely wired, double check the integrity of the
wiring and ensure that the earth connection has been completed properly before powering
up.
8.1
Testing wiring integrity
Work carefully through the following steps, use a multimeter or similar tool for the electrical
measurements.
1. Check there is no electric current flow between the cables and earthing system.
For accurate measurement, remove the extractable terminal boards from the motherboard.
2. Check there is no electric current flow between the cable shields and earthing system.
For accurate measurement, disconnect the shields from the respective terminals by removing the
extractable terminal boards.
3. Check the wiring integrity of each NAC output.
For accurate measurement, remove the respective extractable terminal boards from the motherboard
and measure the cable resistance. Test both polarities, at least one of them must have the same
resistance as the EOL resistance.
4. Check all cables are adequately separated, bunched (by means of cable ties) and attached firmly to the
cable hooks on the back of the enclosure.
5. Check the proper polarity of the primary power supply connections (230 Vac) and ensure the wire is
attached firmly (by means of a cable tie) to a cable hook on the back of the enclosure.
6. Ensure that the connected repeater panel DIP microswitches have been properly set (refer to paragraph
7.10.1 Setting the devices connected to the RS485 BUS
).
7. Ensure that the EOL jumper [figure 42] is in the EOL position on the last repeater panel only.
8. If several panels are connected in a token ring network, check the integrity of the ring, as follows:
9. extract the network terminal boards from the SmartLoop/NET board (refer to paragraph
5.1.2 The
SmartLoop/NET board
) of one of the panels and check the continuity of wiring in the D+ circuit
(between the D+ poles of ports A and B), and in the D- circuit (between the D- poles of ports A and B).
8.2
First power up
1. Insert the jumper for programming-data storage (paragraph
4.2 - [G]
); data storage is guaranteed by
the 2032 lithium battery.
2. Connect the two 17Ah batteries as described in paragraph
7.16.4 Connecting the batteries
.
3. The panel will take several seconds to stabilize and the screen will show “
Resetting
”.
4. The “CPU FAULT” LED on the frontplate will blink to indicate board activation.
5. If the connection with mains power supply is not detected within 2 minutes, the control panel will signal
a fault. Power the panel from the mains.
6. If at this point the panel signals other faults, check the wiring integrity and clear all faults before
continuing (refer to
Chapter 10 - Troubleshooting
).
