Introduction
The TC2-ES is a direct replacement for the earlier HS series power supplies used with Open Date
Thermocode 2 series printers. The unit has been designed to make installation, on-site servicing
and replacement as easy as possible with these key advantages:
 Automatic selection of mains input voltage. Range 100 to 240Vac.
 Lighter and more compact than earlier HS type PSU.
 The same case design and many of the same parts as the Open Date iQ printer.
 Easy replacement of PSU modules and stepper drives on site.
 Easy connection of NPN and PNP sensors for print triggering.
 User selectable leading/trailing edge print triggering.
 Three features that make connection and disconnection easy:
1. IEC C14 Mains connector (uses IEC C13 power cable )
2. Un-pluggable I/O terminals for encoder, print trigger and relays.
3. I/O cable glands on a detachable plate. Unplug terminals, unscrew plate and the unit
is disconnected.

1. Read these instructions carefully. Follow all warnings and instructions marked on the
product.
2. Only use the PSU to operate Open Date Thermocode 2 series printers.
3. Always disconnect the PSU from the mains electrical supply before removing the cover,
connecting/disconnecting the printer cable or attempting to clean or service it. Operating the
PSU with the cover removed exposes dangerous voltages.
4. The PSU should only be installed and operated by persons who have been trained correctly
to do so.
5. Do not operate the PSU near water. Never spill liquid of any kind on it and do not operate it
if liquid has been spilt on to it. The PSU must be checked by qualified personnel before
resuming use.
6. Do not place the PSU on an unstable stand or table. It may fall causing serious injury to the
operator or damage.
7. Never insert objects of any kind into the PSU through openings or gaps as they may touch
dangerous voltage points or short circuit parts that could result in fire or electric shock.
8. The PSU should only be connected to the type of electrical supply as indicated on the label
located on the rear.
9. Use a three core mains cable of at least 5A capacity terminated with an IEC C13 or C15
connector The earth conductor must be connected to a suitable earth point at the electrical
supply. It is dangerous to operate the PSU if it is not properly earthed.
10. Route the power cable so it cannot be damaged.
11. If an extension cable is used with this product, make sure that the total ampere ratings of
the equipment plugged into the extension cable does not exceed the extension cable
ampere rating. Also make sure that the total rating does not exceed the fuse rating.
12. Replace blown fuses with the same type and rating only.
13. Refer all servicing and maintenance to Open Date or suitably qualified personnel.
14. Do not attempt to use to use this product in areas where explosive gases or substances are
present.
15. Under the following conditions always disconnect the electrical supply and refer to a
qualified service engineer.
a. If cables are damaged or frayed.
b. If liquid has been spilled onto the product.
c. If the product does not operate normally when these instructions are followed.

I/O connection details
TO AVOID DAMAGE AND RISK OF ELECTRIC SHOCK CONNECTIONS MUST ONLY
BE MADE WITH THE POWER CABLE DISCONNECTED.
(Refer to the diagram on page 5.)
The protective earth (mains conductor), the 0V terminals of the internal power supply modules,
the 0V of the print head and the 0V from the printer electronics are all common.
ENCODER (J5)
Used with continuous printers only.
Connect encoder +ive wire to 5V or 24V (depending on encoder voltage)
Connect encoder 0V wire to 0V terminal
Connect encoder pulse output (Q) to E terminal
Maximum current from 5V terminal; 100mA
PRINT TRIGGERING:
See page 7 for selection of Leading or Trailing print trigger.
Volt free triggering
Use external relay or switch with volt free contacts.
Connect the Trig (TR) terminal to 24V terminal or.
Connect the Trig (TR) terminal to 0V terminal.
~~~~~~~~~~~~~~Do not connect the 24V and 0V terminals together.~~~~~~~~~~~~~~~
Voltage triggering
Connect voltage trigger source to terminals V and V. Any voltage from 10 to 30V may be used,
polarity is un-important.
PNP/NPN sensor triggering
Connect sensor +ive wire (usually brown) to 24V terminal
Connect sensor 0V wire (usually blue) to 0V terminal
Connect sensor output wire (Q, usually black or white) to TR terminal (See * below)
*Diode type 1N4007 may needed in the Q wire from the sensor for correct
operation. (anode to Q, cathode to TR )
The PSU configures automatically for PNP or NPN sensors.

F2 T2A ’Wickmann’ 48V stepper motor drives.
F3 7.5A automotive 24V switched output to print head.
F4 T2A ‘Wickmann’ 5V output from dc/dc converter.
Located under the mains inlet on the front panel:
F5 T2A HRC 20 x 5mm Mains.
Note: The 5V and 9Vdc supplies are derived from the 24Vdc supply. If fuse F1 blows the 5 and
9V supplies will not be present.
PRINT TRIGGER SETTING
Printing can be triggered on the leading (trigger switch closes) or trailing (trigger switch opens)
edges by setting the jumper link shown above to the A or B position.
Position A Printing is triggered at the start of a trigger pulse (leading edge).
Position B Printing is triggered at the end of a trigger pulse (trailing edge).
NB. The jumper link must be fitted to position A or B. A trigger pulse will not be generated if the
link is not fitted.
DISCONNECT THE MAINS CABLE BEFORE OPENING THE CASE
DO NOT WORK ON THE PSU WITH THE MAINS CABLE CONNECTED
Diagram below shows location of DC fuses and print trigger setting link on the rear of
the main PCB, accessible from the right hand side of the PSU.
Attention is drawn to the warning label indicating the presence of dangerous voltages on
the PCB.
