1.1 General

This instruction manual describes the installation and

operation of the 4234 600 Series Power Supply Unit (PSU),

designed to provide a stabilised (optional 500, 400, 350, 250

or 180 mA) d.c. supply for operation of a single katharometer

unit and an auxiliary 10 V d.c. supply for katharometer

temperature control.

1.2 Description – Fig. 1.1

The PSU is available in two separate versions defined in

Section 2.

The unit is housed in a metal case fitted with mounting lugs.

Cable gland entries are provided at opposite ends of the case

for supply voltage input and output cables respectively.

A printed circuit board assembly (see Fig. 1.1) contains the

circuit components. The supply voltage input is connected to

terminal block (TB1) located on the pcb, adjacent to the fuses

F2 and F3. The constant current output terminal block (TB2) is

located on the gland assembly at the opposite end of the

assembly. The auxiliary 10 V output terminal block (AUX 10V)

is located on the PCB near to TB1. The pcb is mounted on a

steel chassis and secured by six screws. The cover is

perforated to allow ventilation for cooling.

Note. The PSU has NO serviceable parts.

Two identical fuses (L & N) are mounted within the unit on the

mains input. A third fuse is connected in the d.c. line circuit of

the transformer. A fourth fuse is connected in the auxiliary

10 V d.c. line. The L & N fuses are a high breaking capacity

type and must only be replaced with identical types. See

Section 2 for rating.

4.1 Interconnection Diagrams and Cable

Requirements

See Fig. 4.1 for interconnections for typical gas analysis

systems.

4.1.1 Katharometer Connections

Cable connecting the constant current d.c. supply from the PSU

to the katharometer should be selected so that the maximum

cable resistance is less than 2 ohms. This limits the maximum

cable length between the katharometer and its associated PSU.

Note that the cable gland will accept a cable between 5 to 9 mm

in diameter.

4.1.2 Temperature Control Circuit

The cable connecting the auxiliary 10 V d.c. supply to the

katharometer temperature control circuit must have cable

conductance capable of passing 1 amp without undue voltage

drop or excessive heating.

Note also that the cable gland will accept a cable between 5 to

9 mm in diameter.

To gain access, remove the four

screws and lift off the cover.

4.2 Accessing the PSU Terminals

Warning. If the PSU is cubicle mounted or has its

cover removed for test purposes, a.c. mains supply

voltage is exposed at certain locations within the

assembly when supplies are connected. Thus, there is a

risk of electrocution.

All normal precautions must be taken to avoid the risk of

accidental electrical shock during installation and

maintenance of the equipment. Ensure that the supply

cable is disconnected at its source before touching any

electrical connections.

Caution. Ensure that the correct version of the unit

has been supplied for the supply voltage available. A 115 V

unit cannot be used with a 230 V supply or vice versa.

Check that the current output meets the katharometer

input requirements (see katharometer data label) – see

Fig. 4.4. If in doubt contact ABB Limited.

Remove the power supply unit cover to obtain access to the

separate labelled terminal blocks – see Fig. 4.2.

4.3 Electrical Connections

The mains terminal block, TB1, is situated next to the transformer,

T1, and fuses, F2 and F3.

Connect the a.c. mains input cable as in Fig. 4.3.

Note. Earth bonding to be made via M5 Earth Stud.

Connect the d.c. output and 10 V cables as in Fig. 4.4.

5 SERVICING

5.1 Fuse Replacement

There are no serviceable components in these PSU's other than to replace the fuses – see Fig. 5.1. These fuses must be replaced

only with those stated in the specification. If a fault occurs the PSU should be returned to the nearest ABB Service Centre, or

returned to the factory for repair.
