Use

The unit is intended for drying and storing welding electrodes in the temperature range 50-400

The unit is to be used only in accordance with these instructions. Is must not be used for any other

purpose because of possible injuries or material damage.

Before use

Check the unit for transport damage; do not connect a faulty unit to the mains. Check that the

voltage and frequency marked on the rating plate match the values of the mains to which the unit is

to be connected.

Location and connection to mains

To avoid overheating, the clearance to any material must be no less than 0,5 m on any side and no

less than 1 m above the unit. Make sure that there are no obstacles and no flammable material closer

to the unit. The unit must never be covered. Place the unit in a dry place on a flat surface. The

enclosure class of the cabinet is IP 21, thus it cannot be used if susceptible to splashing water. The

unit may not be used in environments where there is danger of explosion (EX). The unit is

connected to mains either semi-permanently by screwing the connection cord to the wall outlet or by

adding an approved plug to the cord. If the connecting cord is too short it has to be replaced. Never

splice the cord or use extension cords.

Using the unit

Do not load the cabinet with packaged electrodes, they must be taken out of their package first. The

protective nets of the resistors must remain in place during operation. If the amount of electrodes is

much below capacity, the electrodes should be distributed evenly over the middle shelf to minimize

temperature gradients. Connect the unit to the mains. The pilot light (1, Fig. 1) lights up. Turn the

main switch (2) to position 1. Set, in the manner explained below, the drying and storage

temperatures according to the recommendations of the manufacturer of the electrodes. The indicator

light (5) is on whenever the controller has turned the resistor on.

Setting the temperature

The temperature of the cabinet is regulated using a digital temperature controller (4). Set the

temperature instruction as follows: Press and keep depressed the SET button, the display will show

the current temperature instruction. Keeping SET depressed, set the desired temperature using the

arrow buttons. When the desired temperature is shown in the display, release the SET and arrow

buttons. This will cause the display to show the current dryer temperature. The desired drying

temperature is now set. Pressing the arrow button continuously when setting the temperature will

first cause the reading of the temperature instruction to change slowly over approx. 10 degrees, then

rapidly. The temperature setting can be checked at any time by pressing the SET button. This will

cause the temperature instruction to be displayed in the display of the controller.

Other matters to be considered

Keep the cover of the ventilation opening open, whenever the cabinet is at drying temperature. This

will improve the evacuation of moisture from the cabinet. The cover may be screwed down during

prolonged storage cycles. Turn the main switch (2) to position 0 whenever the cabinet is not in use.

Turning the cabinet off by the main switch or disconnecting it from the mains will not erase the

settings.

Basic settings of the control unit

The parameters of the control unit are preset by the manufacturer. However, the utilisation of certain

functions require that these settings be changed. The settings may also change due to entering errors.

The following is a review of the changing of settings, and the original settings of each parameter. If

the operation of the cabinet does not meet your requirements, the present parameter settings should

be changed into the factory settings, and the operation retested.

Enter the programming mode by simultaneously pressing the buttons PRG, SET 1 and the

"concealed button" below PRG. The pilot light I starts flashing, and the symbol of the parameter d1

will appear in the display. The value of the selected parameter is shown in the display by pressing

the SET button. The parameter's value is changed by simultaneously pressing the SET button and

either arrow button. Releasing the SET button will return the parameter symbol to the display. The

value of each parameter setting can be displayed and changed as shown above. Exit the

programming mode by simultaneously pressing the PRG button and the "concealed button". The

device returns to the normal operation mode, if the buttons are not activated within a certain time.

The parameters and their original settings are listed below.

Locking and limiting temperatures

An upper (HS1) and lower limit (LS1) may be set for the drying temperature. If you want to limit

the drying temperature to the range 250 - 350

C, set parameter HS1 to 350 and parameter LS1 to

250. The temperature can thus be locked to a fixed value. By assigning parameter LS1, the value

350 and parameter HS1 the value 351, the drying temperature is locked at 350
