ZR-DC/WBX
Installation and Operating Instructions
INTRODUCTION
The diagram below shows an example of a telemetry system. Your ZR-DC/WBX receiver is a Closed Circuit TV (CCTV)
component which receives instructions from a remote transmitter and translates them into Pulse Width Modulated
(PWM) DC control signals and DC lens drive signals.
Your ZR-DC/WBX receiver takes as its control input a Baxall 20mA twisted-pair telemetry signal or a Baxall coaxial
telemetry signal (where telemetry signals and video signals share the same coaxial cable). The ZR-DC/WBX can drive
a DC Pan/Tilt head, four auxiliaries and three lens functions (zoom, focus and iris).
Your ZR-DC/WBX can store eight preset positions, each with an associated alarm input. Also linked to the alarm inputs
is a volt-free alarm output relay which closes for one second for each new alarm condition. In addition, a software driven
auto pan or preset tour function is provided.
Note
: In order for the auto pan and preset tour functions to operate correctly, the video from the camera must be routed
through the receiver PCB.
Your ZR-DC/WBX also contains a video amplifier, with gain and high-frequency lift. This can improve video transmission
and telemetry reception over longer cable runs.
The ZR-DC/WBX contains a 240V AC to 24V DC power supply which powers the circuit board and a 24V DC Pan/Tilt head.
UNPACKING
Keep your packaging for use if your DC receiver is stored for a time or needs to be returned for whatever reason. The
packaging should contain:
The ZR-DC/WBX receiver
These instructions
Please inform your suppliers and carriers immediately if the product is damaged or any part is missing. Do not attempt
to use it.
MOUNTING
Your ZR-DC/WBX must be permanently and securely fixed at its intended location. Ensure that the mounting surface is
flat to avoid distorting the box and compromising the seals. The ingress protection (IP) rating of the supplied enclosure
is IP65. In order that this is not compromised, suitable cable glands must be used to facilitate cable entry and must be
fitted in accordance with the manufacturers instructions. Cable entry into the enclosure must permit free access to all
other parts for the purposes of maintenance. Cable entry must not obstruct any warning labels or interfere with the correct
operation of the device.
SUPPLY CONNECTIONS
WARNING
SWITCH OFF ALL THE POWER BEFORE CONNECTING THE RECEIVER. YOUR RECEIVER MUST BE EARTHED. THE
PROTECTIVE EARTH CONNECTION MUST BE MADE BEFORE CONNECTING MAINS VOLTAGES. A MEANS OF
DISCONNECTING THE RECEIVER FROM THE MAINS SUPPLY MUST BE PROVIDED AS PART OF THE INSTALLATION AND
MUST BE SITUATED CLOSE BY.
Your ZR-DC/WBX requires connection to a 240V AC supply in accordance with good installation practice. The internal
power supply connections are made at the factory.
Ensure that the power is switched off
. Connect the power wires to
the EARTH (E), NEUTRAL (N) and LIVE (L) terminals on the terminal block fixed to the metal base plate. Ensure that the
incoming power connections are on the opposite side of the terminal block from all the internal connections so that the
