3.1 Extra equipment, accessory

If the cooling unit is installed higher than the plasma torch, a non-return valve must

be installed, see accessories on page 20. Connect the non-return valve to the

“COOLANT SUPPLY TO TORCH” outlet on the reverse of the cooling unit. The

non-return valve closes if the supply pressure drops below 1719 KPa (250 psi),

which ensures that the coolant does not run out of the cooling unit when replacing

consumables.

4 INSTALLATION

The installation must be executed by a professional.

WARNING!

ELECTRIC SHOCKS CAN KILL

Always switch off and lock the machine according to the instructions before

making the electrical connections. If conductors are equipped with mains circuit

breakers, the breaker must be set to off and locked with a padlock to prevent

switching on unintentionally. If the included conductors come from a fuse box, the

affected fuses must be removed and the fuse box cover locked with a padlock. If it

is not possible to use a padlock, the mains circuit breaker or fuse box must have a

red notice displayed indicating that the circuit is being worked on.

CAUTION!

Do not run the pump motor intermittently, it causes unnecessary pump wear.

CAUTION!

Do not use solenoid valves that can close when the pump is operating, the pump can

become damaged.

4.5 Pressure setting

The pressure is controlled by a relief valve next to the pump in the tank. Turn the

pressure setting screw clockwise to increase the pressure and anticlockwise to

reduce the pressure. The pressure is default set to around 1203 KPa (175 psi) at 5.7

l/min. This setting is suitable for plasma torch PT-36 in M3 systems. The setting does

not usually need to be changed if the cooling unit is to be used in any other

application.

Fig. 7. Pressure setting screw

The relief valve allows the coolant to pass through the radiators and back to the

tank.

The pump also has an integrated safety valve, which is default set to be fully open at

1719 KPa (250 psi). It is designed to protect the pump if the external relief valve

jams in the closed position. The relief valve must not be adjusted by the user. If the

external relief valve jams in the closed position and the outlet line is closed, the

pump motor is stopped by a thermostat if the pump temperature exceeds 55 °C.

5 OPERATION

General safety regulations for the handling of the equipment can be found on

page 4. Read through before you start using the equipment!

WARNING!

ELECTRIC SHOCKS CAN KILL

Do not rely on the indicator lamp, disconnect the cooling unit from the power

supply and disconnect the cable at the connection before opening the cover or

carrying out any work on the cooling unit.

bk11e

5.1 Control device and indicators

A. Pump manometer

Indicates the pressure at outgoing

connection. The pressure is default set to

around 1169 - 1203 KPa (170-175 psi) at

5.7 l/min. Lower flow gives greater read off

pressure, greater flow gives lower read off

pressure.

Adjust the pressure using a pressure

regulator near to the coolant tank. The

pressure does not usually need adjusting

by the user, if the pressure regulator is not

replaced or the cooling unit is used for an

application that requires a lower pressure.

The pump is protected by a default set

safety valve. The setting for this valve must

not be changed.

B. Indicator lamp for mains voltage ON

Indicates that incoming power supply is on.

C. Indicator lamp for pump ON

Indicates that the pump and fan motor are powered.

D. Switch Auto/Test

In Auto mode, the pump and fan motors are

powered via the power source's control unit.

In test mode, the pump and fan motors are

powered directly.

E. Indicator lamp for overheating

If the coolant flow through the cooling unit is blocked and the pressure regulator

does not work properly, the pump is protected by the integrated safety valve. After a

few minutes operation under these conditions, however, the pump reaches

temperatures so high that it can become damaged. Too high temperature trips the

pump's thermal cutout.

F. Fuse F1 and F2

Fuses for 230 VAC supply for cooling unit to the fan respectively pump motors.
