dimmer will exit the Curve function and store the
curve set up into memory. The “Curve” LED will
remain on, indicating that stored curve set ups are
present in the dimmer. In the event of power
down and power then being restored, the dimmer
will remember its stored curve set up. (Note: The
Curve Setup will only be committed to memory
approximately 5 seconds after the last curve
change.)
3.6 Phase Failure
In the event of a supply phase failure or
disconnection, the ePRO dimmer will indicate to
the operator which phase has dropped out or
moved out of specification. The latter means that
under certain circumstances, the supply voltage
and/or frequency may move outside the
acceptable operating specification and will appear
as a fault to the dimmer.
Three small red LEDs are located in the top of the
Status Display and labelled “A”, “B” and “C” for
phases 1, 2 and 3 respectively. A LED will flash
for the respective phase number when it has
failed or been disconnected. If this fault condition
occurs, it is highly recommended to shut down the
dimmer and correct the fault as soon as possible.
The dimmer’s control electronics is powered by all
three phases, so in the event of any two phases
failing, the electronics will continue to operate.
3.7 User Interface Lock
The front panel User Interface settings may be
locked to protect against accidental pressing of
the scroll or selection push buttons or interference
from unauthorised personnel.
Note: If an error occurs while the User Interface
Lock is active (on), the error messages will scroll
across the Status display, but the buttons will still
be inactive. You will need to unlock the User
Interface to respond to the error.
3.7.1 Locking the User Interface panel
To lock the User Interface panel, the dimmer must
be in the “Drive” state of the following three
modes. Failure to be in this mode will result in the
user not being able to lock the User Interface
panel. The three modes are:
1. Channel Drive mode.
2. Scene Drive mode.
3. Channel Chase Drive mode.
Press and hold both Scroll Buttons for five
seconds. You will enter the Reset function. The
following message will then scroll across the
Status Display – “sys reset inc – yes dec – no”.
INC means the increment (
) Scroll Button and
DEC means the decrement (
) Scroll Button.
Press the decrement button to move to the next
menu. This will bring up a new message on the
Status Display – “total reset inc – yes dec –
no”. Press the decrement button to move to the
next menu. The next message on the Status
Display will be for the User Interface lock – “UI loc
inc – yes dec – no”. Press the increment button
to lock the User Interface panel.
The Status Display will now scroll the following
message – “UI loc active”. If you select “no”, then
the dimmer will return to the condition it was in
when you started.
3.7.2 Unlocking the User Interface panel
To unlock the User Interface panel, press and
hold all three push buttons simultaneously for 5
seconds. This will return the dimmer to the
operating state that was active prior to locking the
User Interface panel.
3.8 Resetting the Dimmer
The ePRO dimmers can perform two types of
reset.
3.8.1 System Reset
Saves all stored information, including the
DMX512 Start Address into its memory and then
does a power down and re-boot of the electronic
circuitry. This is useful to reset the dimmer without
disconnecting power and maintain all stored
memories.
To do a System Reset, press and hold both Scroll
Buttons for five seconds. This can be activated
from any mode the dimmer is in. The following
message will then scroll across the Status Display
– “sys reset inc – yes dec – no”. INC means the
increment (
) Scroll Button and DEC means the
decrement (
) Scroll Button. Press the increment
button to do the System Reset.
3.8.2 Total Reset
clears all stored memory and then does a power
down and re-boot of the electronic circuitry. This
reset returns the dimmer back to its original
default position when it left the factory. The
DMX512 Start Address defaults back to “1”, the
Scene Storage is blank and the curve setting for
each channel is defaulted to the “S Curve”.
For a Total Reset, repeat all the steps to do a
System Reset, but press the decrement button to
say “No” to the System Reset. This will bring up a
new message on the Status Display – “total reset
inc – yes dec – no”. Press the increment button
to do the Total Reset.
At this point if you do not wish to proceed with the
Total Reset, press the decrement button to exit.
