If i
t could be operated but it is not exact, faulty operation, check control equipment and
length of RS-485 data cables that is for a max. 1.2 km.
ⓕ
If the controller is PC, DVR or Web server, check protocol to command for suitable.
ⓖ
If you make configuration with lot of domes in parallel, make sure to turn on TM (No.1)
switch of 5-circuit DIP S/W panel for farthest dome from controller.
*
Use the shielded twist paired cable for data and if you use wiring coil in a same cable to
power or with high power voltage cable in a pack,
ⓗ
If you look into the steps as above, it is not clear, replace the main board.
ⓘ
This dome is self-testing to get the power for less than 18 VAC ± 1 VAC input. If the input is
less than regular voltage, the dome will shut down the system by itself. In order to prevent
the system, i) You have to switch off the power and ii) check for power line and power
system for installation then after recover the power lines, turn on the power switches.
z
If irregular input voltage is detected for 30 second, the system will shut down and you
may get the following messages:
z
< DETECTED LOWER VOLTAGE >
z
“SHUT DOWN VOLTAGE: XX V”
Æ
It appears the shut down voltage due to this voltage
is for 30 second. To prevent system, the dome is shut down by itself.
z
“THE PRESENT VOLTAGE: XX V”
Æ
Even the system shut down, it appears the present
voltage if the voltage is recovered or not from irregular voltage.
