Introduction 4
Revision 2.0c – 30 August 2013 HPC User Manual
2.0 Introduction
The HPC is a professional power control product designed primarily for use in
performance spaces, but has many additional applications. Each of the 12 channels
incorporates a full power dimmer circuit and two high current relays connected as
shown in Figure 1.
Isolate Relay Dimmer
Input Output
Bypass Relay
Figure 1: Channel Organisation
The “Isolate” relay ensures the output can be fully switched off with a real “air gap”
between the input and output, while the “Bypass” relay completely bypasses the
dimmer circuitry ensuring a clean undistorted mains output. Hence each channel can
be used to safely switch power to non-dimmable loads such as moving lights, LED
fixtures, video screens and walls, gobo rotators, fog machines, and other accessories,
or alternatively smoothly dim conventional incandescent loads. Channels may be
individually set to On, Remote Switch, Remote Dim, or Off.
The HPC is controlled using DMX-512-A via a standard 5-pin socket on the front panel.
RDM functionality is provided to enable remote configuration and status readback via
a suitable RDM controller. The dimmed outlets and power entry are located on the
rear panel. The HPC provides easy to use in-built test functions and facilities.
2.1 Features
oRelay pair per channel allows full control of all loads, both dimmable and non-
dimmable. Automatic relay control optimises safety and efficiency.
oDMX-512 address by start channel
oRDM functionality allow remote configuration and status readback
oInbuilt DMX-512 terminator
oTwo DMX snapshots (scenes)
oDimming curve set for linear relationship between control input and output
power
oMultiple phase power operation modes
oDual temperature-controlled DC fans
oTemperature monitor and soft thermal cut-out
oOperates from wide mains supplies 100V to 240VAC, 40 to 66Hz

Getting Started 6
Revision 2.0c – 30 August 2013 HPC User Manual
4.0 Getting Started
The HPC would normally be rack mounted before any wiring is terminated. Refer to
Section 6.0 Installation for installation details.
4.1 Connecting Power
The HPC dimmer may be supplied with a mains inlet cable and multipin connector,
mains inlet cable and no connector, or with no inlet cable fitted. Refer to Section 7.2
for details on mains termination connection methods. Always connect to a supply that
is protected by fuses or circuit breakers at not more than the specified maximum.
Refer to Section 9.0 Technical Data and Specifications.
4.2 Powering Up
Turn on the power and check that the three blue phase power indicator LEDs A, B, and
C are illuminated before connecting any loads. If any of the phase LEDs are dim or off,
power down and remedy the fault before trying again.
If all is well, power down and connect loads.
4.3 Connecting Loads
Switch off the channel circuit breaker before connecting and disconnecting loads.
Ensure any plugs are pushed firmly into their sockets. The HPC dimmer circuit will drive
most incandescent loads as well as pinspots, fans, and dimmable fluorescent tubes.
Un-dimmable loads should not be driven from channels configured to dim (see section
4.3.1).
4.3.1 Changing the Channel Configuration
Each HPC channel may be independently configured to dim, switch, turn fully on, or be
fully off. To change a channel’s configuration:

To record multiple channel configurations at once, repeat steps 1 and 2 until all
channels have been configured, then press and hold any channel button to store all
channels.
4.4 Connecting Control Input
Where DMX control is to be used, the input signal to the HPC should conform to the
specified standard for DMX and RDM. Plug the DMX-512 signal to the “DMX IN” socket.
The DMX signal may be daisy-chained to the next DMX receiver via the LOOP
connector.
The SIGNAL LED indicates the presence of control data.
The DMX-512 input is protected against extreme over-voltages across any input pins
and from any input to chassis. The “terminating” resistor is not protected against over-
voltages.
Where the Ethernet option is fitted, plug the Ethernet data into the front panel
connector. The source of control for DMX and RDM must be manually selected via the
menu between the front panel DMX connector and the Ethernet connector – refer to
Section 5.1.6.
4.4.1 Changing the DMX Address
The DMX-512 address is the DMX-512 channel number that will be used to control HPC
dimmer channel 1. HPC dimmer channels 2 and up are controlled from the next DMX-
512 channel upward.
To change the DMX-512 address:
1. At the root menu adjust the displayed value using the + and – buttons until it
matches the required start channel.
2. Press MENU/to confirm.
4.4.2 DMX Termination
In any DMX-512 system the signal should be terminated at the last dimmer or receiver
in the chain - the HPC can provide this function. Refer to Section 5.1.4.
The TERM LED indicates when the Termination function is active. Note that when
termination is active no signal is present at the LOOP connector.

Revision 2.0c – 30 August 2013 HPC User Manual
5.1.2 Cap Function
The Cap function is used to scale the output voltage of all channels from the maximum
of 240V. This may be used to extend lamp life or allows other voltage loads to be run,
such as 230V or 120V lamps.
Note that the Cap level may be individually set for a channel by selecting that channels
“Mode” button when in the cap menu. If this is the case when the menu is entered the
display will show “---“.
5.1.3 Preheat Function
The Preheat function is used to inject a small amount of power into the lamps when
the control level is set to zero. This provides a small amount of energy to heat the lamp
filament and so minimise thermal shock if they are flashed to full. This may extend
lamp life and reduce the surge on the mains supply at the expense of an increase in
system power consumption.
Adjust the level until the lamps start to glow, then slowly reduce it until the lamps just
go dark.
Note that the Preheat level may be individually set for a channel by selecting that
channels “Mode” button when in the Preheat menu. If this is the case when the menu
is entered the display will show “---“.
This function is ignored for channels set On or to Switch.
5.1.4 DMX Termination
Any long DMX-512 data line must be terminated at the end for correct operation, and
the HPC provides this function. Selecting the “End”option toggles the terminate
function. The TERM LED on the front panel indicates when the DMX-512 is terminated.
Note that no signal is present on the DMX OUT socket when the terminate function is
active.
5.1.5 DMX Data Loss
The HPC can be configured to hold the current output or dim to Scene 1 when DMX-
512 data is interrupted. To set the dimmer to fade to Scene 1, select “SC.1”in the
“no.S”menu. To set the dimmer to hold the current output, select “HLD”in the “No.S
menu.
Note that in both cases the HPC will turn all DMX controlled outputs off if data is not
restored within 10 minutes.
5.1.6 DMX Source
When the Ethernet module is fitted, the source of DMX and RDM can be assigned
between the existing 5 pin DMX connector and the optional Ethernet connector. It is
possible to select between the 4 possible combinations - refer to the following table.
The left digit indicates the source of level information while the right digit indicates the
source of RDM information.

5.1.7 Automatic Relay Control – Bypass Relay
Each channel of the HPC includes relay that when activated bypasses the dimmer
circuit. The HPC includes a automatic bypass mode that activates the Bypass relay if
the channel is dimmed to full for more than about 60 seconds. The bypass relay is
immediately deactivated should the level drop below full. This mode can be globally
activated/deactivated via the “rLC” -> “byp” option in the menu.
Note that the Automatic Bypass function may be individually enabled for each channel
by selecting that channels “Mode” button when in the Bypass menu. If this is the case
when the menu is entered the display will show “---“.
The Bypass relay does not activate for channels where the Cap value does not equal
240.
5.1.8 Automatic Relay Control – Isolate Relay
Each channel of the HPC includes relay that is used to Isolate the dimmer circuit. The
HPC includes an isolate activation mode that automatically activates the Isolate relay if
the channel is dimmed to zero for more than about 60 seconds. This mode can be
activated/deactivated for all channels via the “rLC” -> “iso” option in the menu.
Note that the Automatic Isolate function may be individually enabled for each channel
by selecting that channels “Mode” button when in the Isolate menu. If this is the case
when the menu is entered the display will show “---“.
The Isolate relay does not activate for channels where the preheat is set to anything
other than 0.
5.2 Deep Clear
The HPC includes a deep clear facility to enable the internal processor to be reset to
the factory default settings. In general this should not be required however if
necessary the following procedure should be followed:
1 Turn HPC power off
2Press and hold the “+” and “-“ buttons
3Turn the HPC power on
4Release the buttons held in step 2
5Press the MENU/button

Dimmer Operation 13
Revision 2.0c – 30 August 2013 HPC User Manual
5.3 RDM Facility
RDM is a specification for a protocol that enables a RDM “controller” to set and alter
parameters within a RDM “device” via the DMX-512 connection. An RDM system
consists of one RDM controller and at least one RDM device. The HPC is an RDM
device.
The HPC includes RDM commands that enable most of the parameters in its menu to
be altered and to change the function of each channel between On, Off, Dim, and
Switch. Refer to Section 9.2 for further information regarding the RDM commands
implemented by the HPC.
In general a RDM controller should automatically “discover” the HPC (and any other
connected/powered devices) when it’s turned on. If not, ensure RDM Discovery is
enabled in the controller, power up the HPC, and re-initiate Discovery on the
controller. Refer to the operation manual for the controller regarding how to use it to
read/alter HPC parameters.
When using the DMX connection, all RDM commands are received on pins 2 and 3 of
the DMX cable.

Fault Diagnosis 14
Revision 2.0c – 30 August 2013 HPC User Manual
6.0 Fault Diagnosis
NOTE
Contact your authorised JANDS Distributor for repairs or servicing.
In Australia refer all repairs to an authorised JANDS service agent or
return the faulty unit in suitable packaging to:
JANDS PTY LTD Service Dept,
2-26 Kent Rd
Mascot NSW 2020
Australia
6.1 Output protection
Each of the output circuits is protected by a fast-acting thermal/magnetic circuit
breaker. These breakers are designed to pass the rated current, but will disconnect the
output circuit for any overload condition (the larger the overload, the quicker the
disconnection). If a circuit breaker trips there’s either a fault which should be rectified
or the channel is overloaded.
6.2 Thermal Protection
The HPC dimmers feature temperature-controlled fan cooling. As the internal
temperature of the dimmer increases, the fan speed increases. The inlet and exhaust
areas of the chassis must be kept clear while the HPC is on.
The HPC continuously monitors the internal heatsink temperature. As the temperature
approaches the rated maximum the internal processor attempts to reduce the heat
build up by reducing the output levels. If the temperature continues to rise the dimmer
will shut down the output drive, however this should only be necessary if there is
inadequate ventilation or if the ambient temperature is above the rated maximum.
Refer to Section 7.1 Ventilation regarding HPC ventilation requirements.
6.3 Neutral-Earth Detection
The HPC includes a fault detector that monitors the Neutral-Earth (N-E) voltage – in
normal operation there should be little of no voltage difference between the Neutral
and Earth. If the voltage exceeds a predetermined amount the outputs are turned off.
The N-E fault detector may be disabled in the menu.

rack units. The HPC is supplied with rear rack mounting support brackets, which
provide additional support for touring applications.
The mains supply power cable entry is located at the rear right side of the rack when
viewed from the front. Ensure adequate access to the power plug when mounting
HPC’s in racks.
7.1 Ventilation
The HPC dimmer is fan-cooled, with the air intake at the right and air exhaust at the
left when viewed from the front. Equipment racks must have adequate ventilation for
the side-to-side airflow. Fully enclosed racks will cause overheating problems.
Racks must allow at least 100 square centimetres of air venting per HPC at each side
of the rack, level with the intake and exhaust slots. Additional venting area will serve to
further reduce internal temperatures and will enhance the HPC’s operational
reliability.
HPC’s may be stacked in racks without intervening rack spaces as long as the racks are
adequately vented at the sides. Racks of HPC’s must be placed such that one rack does
not breathe the hot exhaust of the rack next to it. Allow at least 300mm (12") between
racks unless duty cycles are light.
The inlet air temperature must not exceed the specified maximum ambient air
temperature.
7.2 Supply Wiring
The HPC has been designed to run from commonly found star power systems, ie.
where a neutral is available. The incoming mains supply must be protected at not more
than the specified maximum.
The HPC must have its labelled terminals connected to the supply phases as indicated
in Table 3.

Maintenance 17
Revision 2.0c – 30 August 2013 HPC User Manual
8.0 Maintenance
With care, the HPC will require little or no maintenance. However periodic electrical
safety checks may be required by law in some countries.
8.1 External Cleaning
If the front panel requires cleaning, wipe with a mild detergent on a damp soft cloth.
DO NOT allow liquids into the chassis.
DO NOT spray liquids onto the front panel.
DO NOT use solvents for cleaning the front panel.
8.2 Internal Cleaning
The HPC will require little internal maintenance other than periodic flushing to prevent
the fan and air-path becoming clogged with dirt or fluff.
1. ISOLATE POWER to the dimmer (by disconnecting the power cable or locking
off the mains supply isolator).
2. Remove the lid.
3. Blow clean the fan and internals with compressed air from left to right. DO
NOT "spin" the fan with compressed air - the blades may break off.
4. When the fan and internals are clean, replace the lid and screws, and re-
connect the power cable.
8.3 Routine Maintenance
Installed HPC’s should be routinely flushed of dust at six- to twelve-month periods.
Touring HPC’s may need a more rigorous maintenance routine, which should include:
•Inspection of chassis for evidence of impact damage and physical abuse
•Inspection of outlets for wear and damage
•Inspection of power cable for wear and damage
•Electrical checking of ground integrity from power cable to chassis
•Electrical checking of ground integrity from power cable to outlet grounds
•Flushing of dust build-up
•Testing the operation of all front panel switches and breakers
A Neutral-Earth test may show a low reading. This is normal and is a consequence of
the N-E voltage detector detailed in Section 6.4.
