equipment (for International Standards refer to I.E.C/ directive IEC950).
WARNING
It is important that the IHMC6-3 is not mounted directly to any flammable material
i.e. wood. It is recommended that the heatsink be speced off the mounting wall
using pillars to aid in heat dissipation.

INTRODUCTION
The IHMC6-3 is a microprocessor based power controller which has been
designed to offer variable control for 3 separate 2kW loads from a 3-phase supply.
The units have been manufactured to offer easy installation and functionality.
The system consists of three elements: A HMI unit 1 (Human Machine Interface)
which is wired via a low voltage 4-core cable to the main power unit 2, this then
allows the operator to vary the output from off and 30% to 100% via a 10 step
output. All the HMI functions are also available via the infra-red remote control
handset 3.
Additionally you can switch off all the channels or individual channels as
required via the HMI. The main power unit which has been built into a smart
robust IP65 rated enclosure can be mounted remotely from the HMI unit. The
main power unit can also link up to an additional 2 power units allowing you to
control 9 individual 2kW outputs or 8 other power units allowing you to control
9 power units (the 3 outputs within each power unit will increase at the same
level in this configuration) up to 54kW in total (2kW x3 outputs x 9 Power units)
Note: see installation for output options.

SET UP
CAUTION! Ensure the 3 phase supply is
disconnected before proceeding.
Connect the 3 phase supply 415VAC with Neutral
and Earth to the terminals marked ‘L1, L2, L3
Neutral and Earth’ ensuring the phase rotation is
correct, so connect the leads like this:
Brown (L1) Black (L2) Grey (L3)
Connect the 3 X 2KW Lamp Loads to the
terminals marked ‘T1, T2, T3, star connected to
Neutral’.
Configure the oscilloscope to measure AC mains
voltage and connect one of the scope’s channels
across a lamp load.
Connect the HMI unit to the main controller using
four core twisted cable (included) to the terminals
marked A, B, 24v. COM on both units.
Set DIP SW1 to 1000 this sets the controller to
operate on channels 1,2 and 3 using either the
handset or HMI unit, see Table A and B on the
right hand side of the control pcb.
TEST
CAUTION! Beware of hazardous voltages while
testing!
Switch on the 3 phase supply to the IHMC6-3 and
verify the green ‘POWER’ LED is lit and the HMI
digits are lit. When the main power controller
is sending data back to the HMI unit the red
‘STATUS’ LED will pulse.
Using the HMI push buttons step through the
channels and power levels indicated by the UP
and DOWN arrows on the fascia.
Leave all three channels powered up to three
different output levels, press the ALL ON/OFF
button once this will turn all three channels off,
press the button again this will reinstate the
outputs to the power levels previously selected.
Pressing the CH OFF button turns the indicated
channel off, to turn it on again use the POWER up
button.
Switch off the mains power to the controller
and wait a few seconds then re-apply the mains
power, all the controller outputs will be in the off
state, when the ALL ON/OFF button is pressed the
previously selected channels and output levels will
be re-instated.
These tests can also be done using the handset,
with the handset the channels can be selected
individually by pressing the buttons numbered 1,
2 and 3.
With the DIP switch code set to 1000 the HMI
unit will scroll around channels 1 2 and 3, with
the code set to 1100 the HMI unit will display and
scroll around channels 4, 5 and 6. With the code
set to 1110 channels 7, 8 and 9 will be activated
in the same manner.
Next set the controller to three phase three
channel tracking where all three outputs are
controlled as one channel this mode is selected by
setting the DIP switch code to 0001.
With DIP switch code set to 0001 channel 1
will be selected and displayed on the HMI unit.
Adjusting the POWER up and down buttons will
result in all three phases having the same output
levels through 0 to F.
Check that the HMI unit does not respond to any
other channel selection.
After testing return the DIP SW1 code to 1000.
Switch off the 3 phase 415VAC mains supply
and disconnect the IHMC6-3 - the test is now
complete.

SYSTEM PARTS
HMI
The HMI allows the user to control up to 9
individual BHC4002-ER units either via the push
buttons on the HMI or via the Remote Handset
and depending on selected configuration control
the outputs by varying the settings from 1 to 10.
All together you can preset 6 individual outputs
with a maximum rating of 36kW dependant on
configuration. The HMI can switch off all the
outputs together or on an individual basis. When
the units are switched back on they resume the
setting previously set.
The power unit
The IHMC6-3 is designed to accept a 230V one
phase supply. The unit has a 2 stage supply filter
to meet EMC legislation and comes in an IP65
rated enclosure complete with glands. A 4 core
low voltage cable is required to wire the Power
unit to the HMI allow it to be mounted neatly
away from the main installation
The Interface unit is designed to be used with the
Remote handset, however you can also control all
the heaters directly from this unit.
Channel Indicator
This indicates which channel you are controlling.
The maximum number of channels available are
9.
Power Indicator
This indicates the power output
CH OFF
This allows you to switch off an individual
channels
ALL ON/OFF
This allows you to switch the output off to all the
channels

CONFIGURATION OPTIONS
The IHMC6-3 has been designed and tested to allow each controller to be mapped to
either 2 channels (2 power level settings per 2 outputs) or 1 channel (1 power level
setting per 2 outputs).
Please note that no mapped channels should appear with the same channels
numbers.
