desire and then hit "ENTER" and that
will be the mode which will be in
current operation.
If Master Mode is selected the next
screen that you will see is found below:
Run Current Prog
Go to ProgDay:001
If you wish to run your current program
as you have been running it then just
select "Run Current Prog".
The current program is running in
the background when you are in the
Manual Mode. If you wish to jump
to another program day (any other
program day) you would SCROLL
DOWN WITH THE ARROW KEYS IN THIS
INTERFACE TO THE "Go to Prog Day" line
and use the arrow key to change the
program day that you wish to move
to. Hit the ENTER key when you are on
the program day you wish to move to
and then the Master Program is reset to
start running again from that program
day forward.
Protection
● Overcurrent Protection
If the load current exceeds the
overcurrent limit (9A in 110V
AC
system, 5A in 220V
AC system), then
the overcurrent error state is displayed
on the LCD and the alarm LED will
blink. The screen that displays the
overcurrent error state is as follows:
Over Current
Z1 is stopped at
AC 5A
Press Power Key
Fig. 20: Overcurrent error state window
If an overcurrent fault has occurred,
the Plasson Dimmer-Controller will
immediately cut o the output power
to the bulbs/lamps. If the cause of the
overcurrent is corrected then you must
push the "POWER" button and then
the dimmer will be recovered back to
normal operation.
● Overvoltage Protection
If the input voltage exceeds the
programmed overvoltage limit (160VAC
in 110V system, 260VAC in 220V system),
then the overvoltage error state is
displayed on the LCD and the alarm
LED will blink. The screen that displays
the overvoltage error state is as follows:
Over Voltage
InVolt is over
AC 260V
Check Input Volt
Fig. 21: Overvoltage error state window
If an overvoltage fault has occurred, the
Plasson Dimmer-Controller will cut o
the output power. If the overvoltage
issue is corrected, then dimmer will be
recovered in normal operation after 10
seconds.
