Betapack 2 and Betapack 2 Plus
The Zero 88 Betapack 2 and Betapack 2
Plus
range of
dimmer packs are 4U high professional six channel
power controllers capable of driving up to 10 Amps of
lighting loads per channel. Channel protection via
breakers or fuses. Lighting loads may be resistive or
inductive and include tungsten, transformer driven low
voltage (eg. pinspots), and quartz halogen. Some highly
inductive loads such as neon may require the preheat
setting to be adjusted to give smooth control.
Front Panel Controls
Tamperproof Plate (DMX versions only)
Each Betapack 2 with DMX is supplied fitted with a
tamperproof plate to prevent unauthorised users from
changing the controls. The plate covers the front panel
controls but allows all the LEDs to be clearly seen.
Remove the centre screw at the top of the plate to
access the controls.
Channel Test Switches (Not Betapack 2 Plus)
Each channel has a push on/push off test switch. The
‘on’ level for all channels is set by the test level preset
which is above and to the right of the test switches.
A small screwdriver is required to adjust this control.
Green Channel Output Lights
These are next to the channel test switches and give an
approximate indication of channel output level. They
also show the drive to the triac control elements is
working correctly.
Channel Preheat
Each pair of channels has a preheat adjustment.
These are located next to the Channel Output Lights.
They are used to set the minimum output level of both
channels when the output of any controller connected is
set to zero. A small screwdriver is required to adjust
these controls.
Fuse Blown Neons
Where fitted these are next to each channel fuse and will
glow if the fuse is blown.
Plus / Minus Desk Supply
The LED indicator shows the polarity of the supply
voltage on pin 7 of the analogue DIN connector.
Red is +20v, Green is -20v. Check compatibility with the
desk before connecting.
To change the polarity setting, move the switch adjacent
to the 8pin DIN socket.
Note
: If pin 7 of the signal connector of several packs are
joined together, all power leds will come on when power
is supplied to any of the packs.
Using Betapack 2 Plus with remote inputs
When using a remote control input, ensure that all the
faders on the pack are at 0. Mixing local and remote
control will result in the highest signal taking precedence.
Owners Information
DMX Address Switches
These set the DMX Start Address and are located
next to the XLR 5 DMX connectors. A small
screwdriver or trim tool is required to adjust the
address settings.
Fade / Hold Switch
This sets how the pack will behave if the DMX signal
is lost.
When set to HOLD the last DMX data received will
be stored and output until either the DMX control
signal is restored or the unit is switched off.
When set to FADE the unit will fade all outputs to
zero after one second. This allows the use of an
analogue control desk as a backup control system.
In either position the control inputs are mixed on a
highest takes precedence basis.
DMX ‘OK’ and ‘Error’ LEDs
These are located above the DMX Address switches
- they show a variety of information:
7367000/p1/2
DMX dimmer data (with Start Byte
of ‘00’) is being received OK.
DMX data is being received OK, but
it is not dimmer data (the Start Byte
is not ‘00’)**
DMX data errors are occuring. This
is normally due to transmission
speed errors, bad connections,
wrong cable, interference or poor or
missing line termination.
Check the output from the control
desk and the connecting cables using a
DMX checker such as the test
mode of a Zero 88 Linebacker.
A terminator plug may be required in
the last device on the DMX control line,
or the built in termination may
be used (see below).
No DMX data has been detected.

** When mixed dimmer and other DMX data is being sent
together, the DMX ‘Error’ LED may flash.
This is normal.
