6.5.5 To set up DMX Backup preset
1. Press INST.
2. Press Ð or Ï to choose DMX BACKUP
menu. Press ENT.
3. The screen shows:
L:  242V
CH:T123456 00 A
4. Use Í or Î to select a channel number
(active channel number is underlined) or
T if all channels are to be set together.
5. Press Ï or Ð to adjust the backup level.
The dimmer output is live while the
backup levels are adjusted.
6. Press ENT to leave the menu and
record the changes or EXIT (to leave
the previous settings unchanged).
6.5.6 To set up a DMX Minimum reset
In order to reduce dynamic filament noise in some
types of 120V PAR lamps, it is sometimes
necessary to use a low preheat level. DMX
minimum reset is the automatic means to switch
any preheat levels off when DMX is not present
(i.e. when the control desk is switched off, but the
dimmers remain on).
1. Press INST.
2. Press Ð or Ï to choose GENERAL
SETTINGS menu.
Press ENT.
3. Press Ð or Ï to choose MIN RESET
menu. Press ENT.
4. The screen shows:
GENERAL
MIN RESET: [OFF]
5. Use Ï or Ð to select either AUTO
(preheat switches off when DMX is off)
or OFF (preheat runs continuously).
6. Press ENT to leave the menu and
record the changes or EXIT (to leave
the previous settings unchanged).
6.6 Serial address (PC address)
The DimSTAT PC address shown on the output
screen as A:XXX is the unique number which is
used by network to identify each dimmer unit for
the purpose of reporting status information and for
transferring data between the dimmer unit and PC.
If a dimmer unit is removed from the network and
replaced by another, DimSTAT will automatically
prompt for an update of configuration information
when the PC address is entered. DimSTAT
identifies the new unit on the network, and
prompts the operator to download the previous
characteristics file from the PC to the new dimmer.
The PC address is associated with a unique
factory serial number which is permanently stored
in the dimmer. An Autoreload function is also
provided to reinstate the PC address after a
factory reset.
6.6.1 To set up a serial address
1. Press INST.
2. Press Ð or Ï to choose DIMSTAT
ADDRESS menu. Press ENT.
3. The screen shows:
ADDRESS: [001]
AUTO-RELOAD NO
4. Press Ï or Ð to set the address number
between 001 and 255.
5. Press Î to select auto-reload options of
YES or NO.
Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
6.7 Maximum & Minimum levels
It is possible to affect the output range of a
dimmer by setting a minimum level and/or a
maximum level. A minimum level is used to
provide a pre-heat to preheat lamp filaments,
whereas the maximum level is used to limit power
and extend lamp life. Minimum levels may be set
between 0% to 29.9%, and maximum levels from
30% to 100%. Factory default levels are 0% for
minimum and 100% for maximum. One common
use for a reduced maximum level is to control
110 V lamps but the 110 V dimmer curve is
recommended as it produces a smoother control
over the whole range of intensity. However the
operation of this channel should be compared with
other lamps in the rig to ensure uniformity of
response.
Note: In the case of high inrush loads (e.g. PAR
cans) where flashing on from a cold
state is required in a silent auditorium, or
for 5kW lamps where the high inrush
current could cause the shortcircuit
protection to report and error, it is
recommended to set a ‘minimum’
preheat level to 5%. See also the
section on DMX Minimum Reset.
6.7.1 To set-up max and min levels
1. Press CONF.
The screen shows the individual channel
number (or T if the dimmer set-up
scheme copies characteristics to all
dimmers in the rack) and gives access
to all configuration options.
