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.
‘OK’ ‘Error’
(Green) (Red)

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

Removing the Covers
Disconnect the Betapack at the supply.
The mains supply connections and the channel output
terminals (Betapack 2 hardwired version only) are
under the top cover.
Remove the four screws (‘A’ in Diagram 6) from the
end plates to remove the cover.
The DMX links and the triacs are under the bottom
cover. Remove four screws (‘B’ in Diagram 6) from the
end plates to remove the cover.
Connecting the Mains
A separate isolator and secure mains earth
are required.
Phase to Neutral voltage must not exceed 255v.
Betapack 2s are supplied wired for single phase
operation. Cut outs are provided on the ends and rear
for PG21 glands; one is supplied.
Single Phase
Betapack 2s are supplied from the factory with two
busbars wired for single phase as in Diagram 2.
If the busbar for linking Live 1 to Live 2 to Live 3 is not
available, use 10mm2cable instead.
Three Phase ‘Star’
Remove the single phase busbar (if fitted) from across
the three phase input terminals Live 1,
Live 2 & Live 3. Ensure that the neutral busbar is in
place as shown in diagram 3 opposite.
Wire the supply to Live 1, Live 2, Live 3 and Neutral
using at least 2.5 mm2cable.
Three Phase ‘Delta’
Using suitable cable (4 to 6mm2) connect the supply
terminals together as shown in Diagram 4 opposite.
Wire the supply to Live 1, Live 2 and Live 3 using at
least 4.0 mm2cable.
Mains Supply Wiring
Always ensure that the lockwashers supplied are
used. Use an M5 ring tag securely crimped to the
mains supply wire if possible.
Otherwise ensure that the mains supply wires are
connected as shown in Diagram 7 and that the screws
are securely tightened.
Ventilation
When one or more Betapack 2s and/or Betapack 2
Plusses are mounted in an enclosed rack, a fan
MUST be fitted to ensure that adequate cool air is
circulated.
Up to three Betapack 2s / Betapack 2 Pluses may be
stacked in free air.
Mounting
In a 19" Rack
The Betapack 2 is supplied with side brackets fitted
for rack mounting.
On a wall
Undo the four screws ‘X’ to remove the brackets,
replace the screws in the holes for future use.
Stand the Betapack 2 on one end. Remove the two
screws ‘Y’ (see Diagram 6), fit the brackets as shown
and replace screws ‘Y’. Fit the other bracket on the
other end.
The wall drilling positions are shown in Diagram 8.
WARNING Completely fit one bracket at a time.
Removal of all four screws ‘Y’ at the same time can
allow the heatsink assembly to fall out!
Allow a minimum vertical spacing of 130mm between
packs and between packs and other equipment.
A spacing of 180mm is recommended for ease of
wiring and servicing.
For Portable Use
An ‘Easicarry’ Option Kit consisting of a handle and
four feet is available (Stock No: 00-540-00). Contact
your dealer for further details.
To fit, remove the brackets. Fit the handle using the
screws supplied and holes ‘Z’. Fit the four feet to the
other end using the holes ‘X’ and ‘Y’. See Diagram 6.
DMX Options (where fitted)
Remove the bottom cover to access these links as
described above.
DMX Control Law
As supplied the Betapack 2 DMX output provides a
linear law control. If a ‘S’ law is required
(eg when the Betapack 2 is part of a system which
has mixed analogue and DMX control), add a short
wire link between ‘LIN’ and ‘0v’ on the DMX Printed
Circuit. (See Diagram 5).
DMX Termination
Each Betapack 2 has a built in DMX termination.
It is connected by adding a short wire link between
‘EOL’ and ‘DMX-’ on the DMX Printed Circuit.
(See Diagram 5).
Connection ‘CHS’ referes to chassis and is unused.
Permanent Installation
Where Betapack 2s are permanently installed it is
possible to connect the DMX control cabling to the
dimmer internally. The terminals marked ‘DMX+’,
‘DMX -’ and ‘OV’ should be used (see Diagram 5).

Portable Appliance Testing
WARNING The Betapack 2 will fail the portable
appliance high voltage test as it has capacitors
connected between Live 1 and Earth and between
Neutral and Earth to enable it to comply with CE
regulations.
Fusing
Channel Outputs
11/4” Fuses
Where appropriate ONLY use 11/4” x 1/4” (32 x
6.3mm) 10A rapid (F) HRC ceramic fuses (Zero 88
Part No 40-110-00).
DO NOT USE Ultra rapid (FF) or time delay (T) (Anti
Surge) fuses.
Cartridge Fuses
Cartridge type fuseholders use 10.3mm x 38mm 10A
HRC Ceramic fuses (Zero 88 Part No 40-120-00).
Neutral Disconnect
Breakers and Cartridge fuse versions isolate the live
and neutral when tripped or open.
Fusing of Inductive Loads
All inductive loads (eg. pinspots, any transformer
driven lamp) must be fitted with a separate fuse of the
correct value per lamp or fitting.
Failure to fit the correct fuse may mean that any
supply disturbances could destroy the lamp
transformer.
For a single pinspot, a 500 mA Quick Blow or 250mA
AntiSurge fuse should be used.
