ALLEN & HEATH PL-2 User manual

PL-2 User Guide AP5080 1
Introduction The PL-2 is a remote control device available for use with
the Allen & Heath DR-switch or iDR-switch logic expanders. It is a wall plate or
furniture mounted module comprising plastic control panel and attached circuit
assembly. It can be mounted in a single unit wall box using a standard face
plate (UK, EU or US version supplied). A pre-cut brushed aluminium EU
(AA5029) or US (AA5030) plate is supplied. The PL-2 interfaces with the
DR/iDR-switch rear panel SWITCH INPUTS and LOGIC outputs ports. The
number of PL-2 units which may be connected is determined by the number of
remote switch and logic output lines from the DR/iDR system and how many
you wire to each PL unit. The wall plate switch and indicator functions are
programmed using the Allen & Heath WinDR (DR-switch) or iDR System
Manager (iDR-switch) software. Space is provided on the control panel for
custom labelling. The following combination of controls makes the PL-2 ideal
as a wall mounted room remote controller in installed audio systems. The
installer can program the unit so that the non-technical operator has local
control using pre-programmed switches LEDs.
4 switches For DR-switch they can be assigned for level up or down control
(input, output, or crosspoint), mute toggle or patch recall. For iDR-switch they
can be assigned for level up or down control (input, output, crosspoint or
group), mute toggle, polarity toggle, audio monitor select, or patch recall. 4
LED indicators For DR-switch they can be assigned to display input or output
channel mute status, or as patch related static indicators. For iDR-switch they
can be assigned as audio meters (choice of 8 points in the signal path), mute
status, polarity status, or as patch related static display. Each can be wired to
display either red or green. Two DR/iDR-switch outputs can be used to switch
one LED to red, green or yellow. Custom labels Recessed areas are provided
for fitting custom adhesive labels. Recommended maximum sizes are 6x26mm
and 26x9mm (h x w).
Note : The PL-2 differs from the PL-1 only in that it
includes an adapter card that fits into the DR/iDR-
switch logic output connector plug. This routes the
+10V reference voltage via resistors to the open
collector ‘+’ pins. You wire the ‘-‘ pins to the PL-2
connectors. The PL-1 does not include the adapter
card.
This product complies with the European
Electromagnetic Compatibility directives 89/336/EEC &
92/31/EEC.
NOTE: Any changes or modifications to the
equipment not approved by Allen & Heath could void
the compliance of the equipment. Whilst we believe
the information in this guide to be reliable we do not
assume responsibility for inaccuracies. We also reserve
the right to make changes in the interest of further
product development.

IMPORTANT :
Observe the local standards which may apply
to the installation regarding the grade of cable and
installation methods.
To ensure operator safety ensure that any
exposed metal face plates are correctly bonded to
ground. Do not install the equipment where it is
subject to moisture, heat or vibration.
Connect this equipment to the Allen & Heath
DR-switch or iDR-switch only. It is very important to
test for correct wiring and installation before
switching the equipment on.
The DR/iDR-switch provides opto-isolated
contact closure switch inputs and open collector
logic outputs. How these are wired to external
equipment is the responsibility of the installer.
Details are provided here for wiring to the PL-2 wall
plate. Allen & Heath do not assume responsibility
for any damage done to the equipment due to
incorrect or faulty installation.

Aligning the arrow keys The four switch
caps can be rotated so that the arrow faces up, down,
left or right. Decide which way you want them to face
according to function, for example volume or source
select.
To change them, first remove the four screws (B) and
lift away the PCB. Rotate the switch caps into the
required position. Reassemble the module.

Mounting into the face plate A pre-cut
brushed aluminium UK (part number AA5029), EU
(AA5250) or US (AA5030) plate is supplied. A backing
box for the UK plate can be supplied (AA5220).
The assembled module fits into an ‘H’ shaped cutout in
the centre of the mounting plate. The module is held
using the two screws with plastic clamps provided (A).
Unscrew these from the module first. Dimensions are
in millimetres below.
Grounding a metal plate If the face
plate is metal make sure that it is correctly grounded to
ensure operator safety. The plate should be connected
to a local safety ground, not the DR/iDR-switch G pin or
cable shield. Use a ground wire or physical contact
with a grounded back box.
Wiring standards Use flame retardent shielded
cable that meets the requirements of the installation.
We recommend the multi-stranded rather than solid
conductor type. Screw terminal blocks are provided for
the switch and LED connections. Use a small flat
bladed screwdriver. Ensure the wires are correctly
stripped and formed to allow sufficient service loop in
the backing box.
Wiring to the DR/iDR-switch Connect
each DR/iDR-switch SWITCH INPUT pin to the required
PL-2 SW terminal. Wire the DR/iDR-switch G (ground)
pin to the PL-2 0V common terminal.
Connect the LOGIC OUTPUT – (emitter) pins to the
required R or G LED terminal as shown below, and 0V
common to the G pin. Link the +10V internal supply to
the output + (collector) pins using the adapter card
AG5222. Connect the cable shield to the ground
terminal next to the LOGIC OUTPUT connectors.

Deciding the LED colour Wire to the G
terminal for green, or to the R terminal for red, or both
for yellow. Wire two logic outputs to G and R of the
same LED to switch between the three colours.
Assigning the controls The function of the
LEDs and switches is assigned using the Allen & Heath
WinDR (DR-switch) or iDR System Manager (iDR-
switch) software. First ensure the wall plates are
correctly wired to the DR/iDR-switch. Connect your PC
to the DR or iDR and run the application. For full
details refer to the application Help file.
