Indicators and Controls Description
1 LCD Display 2 x 40 backlit alphanumeric display.
Used to display the control menu, faults, and configuration data.
power green Lit only if the unit is receiving DC power from both sources.
processor green Flashes to show that the processor is healthy.
comms green
Lit to indicate communication activity between the main processor
and the amplifier units.
Flashes on receipt of a message from an amplifier unit.
2 LEDs
fault amber Lit to indicate that the unit has detected a system fault.
Flashes if a fault has not yet been accepted.
W
X
The left and right arrow keys move the item selection in the
direction selected, to the next item in the menu. The selected item
is indicated by [brackets] around the selection.
S
T
The up and down arrow keys toggle a selection, or increment a
number, or a letter of the alphabet when editing.
The rotary encoder acts in the same manner as these keys, and
enables faster editing.
SELECT Press after selecting an item to confirm the selection.
BACK
Press after selecting an item to cancel the selection.
If pressed repeatedly, this returns the display to the top-level
menu.
DEFAULT Press to clear previously configured text strings quickly during
system configuration, or to return fields to their default values.
FAULT ACCEPT
Accepts all current faults, steadies the flashing fault LED
indication, and turns off the audible alarm until a new fault
condition occurs.
FAULT CLEAR
Clears all faults and sets all connected equipment to the 'no faults'
state, which also cancels any amplifier changeovers in effect. If
there are any faults present in the system then they are detected
anew, and reported again.
AUDIO MON Selects Audio Monitor sub-menu on the LCD display.
3 Keys
LAMP TEST
Tests all indicators on the VAR and on all connected amplifier
units. The sounder is also tested. The display shows ‘LAMP +
SOUNDER TEST’ and the menu locks during this time.
This function is also available from the ‘Tests’ menu.
4 Rotary Encoder
Multi-function:
• An alternative for the Sand Tarrow keys for fast increment
and decrement of menu items.
• During Audio Monitoring it also acts as a volume control.
5 Loudspeaker Dual function: Alarm Sounder and Audio Monitor.

Recommended Installation Procedure
!
!
Please read and observe the instructions and guidelines in Section “5 Safety and Precautions” (page 17)
prior to installation. Failure to follow these instructions and guidelines may cause personal injury and/or
damage to the equipment.
1. Fit the VAR4 into a 19-inch standard equipment rack on supporting rails, and secure the unit in
position using the fixing screws and washers provided; see Figure 1.
!
!
Ensure that there is at least 1U of ventilated space between the unit and any source of heat (e.g.
Amplifier Mainframes).

2. Set the rear-panel EARTH LIFT switch to the ‘grounded’ position ( , ON); see Figure 2.
!
!
Only set the EARTH LIFT switch to the ‘ungrounded’ position ( , OFF) if a +ve ground battery
supply is used.

5. Connect the dual power supply to the rear panel connectors; see Figure 4.
!
!
1) Ensure power supply cabling is adequately rated.
2) Always route power supply cabling away from amplifier input cabling in the equipment rack
to reduce the risk of noise pick-up.
Figure 4 Connecting the DC power supply
Wago Connectors:
Use one of the two methods shown in the dia
g
ram below to terminate
the cabling in the Wago connectors.
When the screwdriver is removed, the bare end of the wire will be held
securely by the contact spring.
To remove the wire, reverse the process.

5 Safety and Precautions
Environmental
Always ensure adequate ventilation is provided for the
equipment by fitting 1U ventilation panels above and
below the equipment and do not obstruct ventilation
holes.
The temperature and humidity ranges shown in the
specifications for this product must not be exceeded.
This equipment must not be installed in an area that is
subject to a corrosive atmosphere, excessive moisture
or may allow water or other liquids to come into contact
with the unit or its external connections.
Electrical Safety
!
!
Ensure power supply cabling is
adequately rated.
Always route power supply cabling away
from amplifier input cabling in the
equipment rack to reduce the risk of noise
pick-up.
!
!
Always replace blown fuses with the
correct type and rating.
ESD Precautions
This product contains static-sensitive devices. Observe
ESD precautions when handling this product.
An ESD bonding point is provided on the rear panel of
the unit.
EMC
In the close proximity of some radio frequency
transmitters, the signal to noise ratio of this product
may be reduced. If this occurs, re-location of the
equipment or the signal cables is recommended.
Lithium Battery
!
!
This product contains a lithium battery.
Danger of explosion if battery is
incorrectly replaced.
Replace only with the same or equivalent
type.
Dispose of battery carefully to avoid
environmental damage.
Do not dispose of battery in a fire.
Unpacking and Handling
The equipment should be unpacked and inspected
immediately on receipt. If damage has occurred please
advise your carrier or supplier.
!
!
This equipment contains electronic
devices that are sensitive to electrostatic
discharge. Please take precautions to
avoid damage to the electronics by static
electricity.
It is advisable to retain the original equipment packing
in the event that the equipment ever needs returning for
service.
Ensure that the name and address of the Authorised
Distributor from whom you purchased the unit is
recorded on the “Service and Warranty” page of this
manual for future reference.
Packing for Return for Repair
!
!
All electronics assemblies must be
properly packed in ESD protective
packing for transport, to prevent physical
and ESD damage.
!
!
The filler material used for packing for
return for repair must be antistatic or
static dissipative, as this may come into
contact with exposed connectors, wiring,
or PCB assemblies. The use of non-
conductive filler material may cause
