Mains power supply indicator light
When lit, denotes mains power to unit.
Channel indicator lights
When lit, denote controlled DC power to appropriate
output terminals. Brighten as power increases.
Channel “ON/OFF” & speed controls
In the fully anti-clockwise position, there is no power
to the controlled DC output and the appropriate light
is “OFF”. Turn knob clockwise to switch on power and
control speed of train. Indicator light will come on.
direction switches
Set switch to either of the two positions to achieve
required train direction. Actual direction will depend
on individual layout wiring arrangements.
“d” Connector
(both sides of unit)
For adding HM 2000+ left-hand and right-hand
DC Controllers.
Output Terminals
1. Channel 1 controlled DC – 550mA maximum
2. Channel 2 controlled DC – 550mA maximum
3. Auxiliary AC
300mA – maximum
4. Auxiliary DC
shared (see note 2)
Please Note:
1. There is no output from the two outer, unmarked,
pairs of terminals. They have been incorporated for
possible use in future developments.
2. Output terminals 3 and 4 can be used for a variety
of electrically-operated accessories such as remotely
controlled points, colour light signals etc. It is important
that the accessory manufacturer’s instructions be
carefully followed to determine whether AC or DC
supply is required.
3. For electrical specification, see label on underside of
unit base.
safety Notes
• This Power Controller is not suitable for children under 14 years of age, and is for indoor use only.
• The Power Controller should be examined regularly for damage to casing, plug, power supply cable
and output wires. In the event of damage to the power supply cable, please replace with a Hornby
recommended cable. This can be obtained from your Hornby Service Dealer. If any part of the Power
Controller unit is damaged, it should not be used until repaired or replaced.
• Before cleaning the Power Controller, or any part of the set, remove the mains plug from the wall socket.
Do not use liquid for cleaning.
• The train set must not be connected to more than the recommended number of power supplies.
• WARNING – The 16 volt AC output terminals of two or more Transformers, or any type of Mains
Powered Controller, must never be connected together, or to circuits which may accidentally become
connected together. The “D” Connectors transfer 16 volt AC current between HM 2000 and HM 2000+
units, so never attempt to connect two HM 2000 Power Controllers together either directly or via an
HM 2000+ DC Controller.
• The Power Unit case should not be opened. It has no customer repairable components. A repair service is
available from Hornby Hobbies Limited.
• Please retain this leaflet for future reference.
• Do not plug any other product into the “D” connectors.
• The leads are fitted with terminal plugs which suit R602
Hornby Power Connecting Clip (Fig. 3). For other track
systems refer to the manufacturer’s instructions for track
connection details.
• If necessary the wires can be changed over in the track
connector to reverse the direction of the train in relation
to the direction switch position.
Note
The two controlled DC channels are supplied from separate,
isolated transformer windings and are therefore not affected
by Common Return problems.
safety Cut-Outs
The two controlled DC channels are protected by separate Polyswitch safety cut-outs and the two auxiliary
circuits are protected by a third Polyswitch. If any of these circuits are subjected to short-circuit or
overheating conditions the power will be shut off to the affected circuit.
This would be indicated by the Mains indicator light going off in the case of an auxiliary circuit fault, and the
appropriate channel indicator light going off if a Controlled DC channel is affected.
Cut-outs can be reset by switching off the mains power socket, or pulling out the plug, for 45-60 seconds.
The fault should be corrected before switching on the power again.
In the event of extreme overheating conditions, a “one-time” thermal fuse will “blow” to protect the Power
Controller. In this event, the Power Controller should be sent to Hornby Hobbies Limited, for attention.

Auxiliary AC Output Terminals
Mains Electricity Supply Cable Connection
Connecting up
• Connect the Power Supply Cable to its socket in the back of the
Power Controller and fit the Mains Plug into a wall socket.
• Two connecting leads are supplied for the DC controlled
channels. Connect the pairs of stripped wire ends to the output
terminals marked “1” and “2” by lifting the spring loaded clips,
inserting the wire ends and releasing the clips. (See Fig. 2).
• Make sure the wire ends are securely retained by the output
terminals. Use the other ends of the leads for connection to your
two train tracks.
