Unpacking
Keep your packaging for use if your AC receiver is stored for a time or
needs to be returned for whatever reason. The packaging should contain:• Your PY-ACW, AC receiver with PS1 or PS5 (24V AC)
• An A4 Module Description sheet (for installation details)
• These Instructions
• Two identical bar-codes
Check the product code on the serial number label. If you have an
incorrect item or it is damaged then inform the suppliers and carriers
immediately. If this is the case then do not attempt to use your AC
receiver.
These Instructions
These instructions allow you to install your Pyramid AC receiver, they
do not contain any application information. As the installer you are
assumed to have a sound knowledge of how AC receivers operate, if you
have not then contact a CCTV installation company for advice.
If you are replacing a receiver on a network which is already operational
then see Manual 1 - Operating Instructions for instructions on connecting
a new receiver using the keyboard.
The connection diagram is shown on the next page. Using this follow the
instructions. The instructions are listed by connector and describe wiring
your AC receiver to the P/T head, the lens, the network and the power
supply.
At the end of the connections section is a description of the on-board test
routine, once the tests are complete and all the connections are correct
your AC receiver needs no maintenance.
Bar Coding
All the pyramid modules are supplied with two identical bar-codes,
remove one and affix it to the module description sheet, remove the other
and affix it to the module.
The bar code gives the unique 48-bit module address. Make a careful
note on your module description sheet of all your installation details and
the location of the module. Then during subsequent installation using the
Windows™ installation tool the module address can be entered (using a
bar code reader) with the description.
Page 4
We recommend that during a system installation you store the module
description sheets in a ring-bound file, and keep them for reference after
the installation is complete.

Connections
Below is a description of each of the connectors. The connections are
described in numeric order, followed by video, network and power
connections.
CON1
CON1 is for the PCB power connection. This power controls the
switching of the relays, the video gain and lift and the lens functions. AC
power for the P/T head and auxiliaries is connected separately to CON5.
The PCB requires a +12V DC ± 10%, 1A class 2 power supply, this is
already connected.
Referring to figure 1 connect the +12V DC and 0V (return) to CON1.
If the polarity is correct when the power is switched on then LED1 (see
figure 1) is green. It appears red for an incorrect polarity.
CON2
If you are using a preset P/T head and lens then CON2 provides the
supplies and feedback (FB) connections for the pot-wiper circuits. The
direction of the feedback is automatically calculated when the test routine
is invoked (see Testing on page 9), this means it is not necessary to wire
the pots in a specific direction.
Referring to figure 1, connect CON2 to the preset pots on the P/T head
and the lens. Connect any unused feedback inputs to ground.
Make a note on your module description sheet of the preset connections
and the type of lens.
CON3
CON3 contains the lens drive outputs for focus, iris and zoom. The drive
voltage is +10V DC at up to 100 mA.
Refer to your lens instructions and connect up your lens according to
figure 1.
CON4
CON4 contains the power output connections for your P/T head and
auxiliaries (AUX A, AUX B, AUX C and AUX D).
Page 6
CAUTION : Your application must not draw more than 1A per relay or
it will damage your AC receiver
CAUTION : Connect lamps using a separate relay because they draw
an initial surge current which may damage your AC receiver
Referring to CON4 on figure 1 connect LEFT, RIGHT, UP and DOWN
to your P/T head and AUX A to wash, AUX B to wipe, AUX C to lamps
and AUX D to camera power. Do not connect any unused auxiliaries.
Connect all the return (neutral) wires to the spare terminals on the
external terminal block.
Make a note on your module description sheet of your auxiliary
connections.
CON5
CON5 accepts the AC power input which is switched to CON4 (pan, tilt
and auxiliaries). It powers the P/T head and auxiliaries.
WARNING : Never use both 24V AC and Mains on the same receiver
PCB.
For mains . . . Referring to figure 1 connect CON5 to the LIVE and
NEUTRAL connections on the external terminal block.
For 24V AC . . . Referring to figure 1 connect CON5 to the SUPPLY
and RETURN connections on the 24V AC power supply.
The middle connection on CON5 is Not Connected (NC).
CON6
CON6 is for an anti-tamper switch input. It is connected in parallel with
the anti-tamper switch shown on figure 1. The anti-tamper switch has a
spring fitted and so you cannot use CON6 (unless you first remove the
spring).
If you are not using the built in anti-tamper switch then connect CON6
on figure 1 to your anti-tamper switch in a N/C configuration.
VIDEO
All video must be via 75 ohm BNC connectors and video coaxial cable.
Your AC receiver has an on-board video amplifier with gain and lift.
Adjustment of gain and lift is done remotely, using a Pyramid keyboard.
Page 7
Referring to figure 1, connect the video from your camera to VIDEO IN,
through your AC receiver, then from VIDEO OUT to the matrix.
NETWORK
CAUTION : To avoid damaging your module switch off the power
before fitting the network card
Switch off the power, fit a network card in the position indicated on
figure 1.
Connect the cable provided from the network card to the filter board
mounted on the metal base plate.
Connect the network to the filter card. The wiring diagram is included on
the sheet provided with the network cards.
POWER
WARNING : Ensure that the power is switched off before connecting
the mains wires
WARNING : Your PY-ACW module must be earthed
Connect the Live, Earth and Neutral wires from the mains supply to Live,
Earth and Neutral on the external terminal block.
Check that all the wiring is correct and switch on the power.
WARNING : Your AC receiver PCB now contains live voltages
LED Power Indicator
LED1 (see figure 1) indicates the polarity of the 12V DC. For correct
polarity it is green, incorrect it is red.
Page 8
Testing
Your AC receiver has an on board test procedure which steps through
outputs in the sequence shown in Table 1. The test push button is shown
in figure 1. The test takes 55 seconds.
Running the test procedure also allows your receiver to detect the
feedback polarities for your P/T head and lens.
WARNING : Your AC receiver PCB now contains live voltages
Using an appropriate tool, press the test push button.

Replacing the Lid
WARNING : Refit the lid securely to prevent unauthorised access
Tighten the four securing screws with an appropriate tool until they
cannot be undone by hand. Do not exceed a torque of 4 Nm.
Maintenance
Once your AC receiver is correctly installed and commissioned it
requires no routine maintenance.
Changing the Fuse
The fuse holder (see figure 1) contains a 10A A/S fuse for protecting the
relay outputs.
To replace the fuse, switch off all power to the module, turn the top anticlockwise using an appropriate tool, change the fuse and replace the top.
