2.4.3

Operating-Hours Meter

Time is counted from program start; not included are delay start and anti-
crease.

The time is stored in the power electronic (ELP).

2.4.4

Operating Functions

Operating functions are indicated.

Check the function visually, acoustically, and by observing the display.

So that all operating functions can be checked, change test conditions
manually (by pressing buttons, for example).

2.5

Demo Mode

2.5.1

Demo Program Mode

Display and LEDs are activated automatically for demonstration.

Electronic components are not switched on.

Activate/deactivate the demo program mode.

See Section 070-4.4.

W 4800, W 4802:

See Section 070-4.2.

2.5.2

Demo Program Mode (Program Simulation)

The appliance can be operated.

Electronic components are not switched on.

Only the LEDs and display indicators light up as in the operating mode.

Activate/deactivate the demo program mode.

W 4840, W 4842:

W 4800, W 4802:

See Section 070-4.2.

2.6 Fault

Dialog

The power electronic (ELP) monitors the electronic sensors.

If the power electronic (ELP) registers a fault, it sends a fault message to the
control electronic (EW).

The control electronic (EW) shows the fault message in the display.

Technical faults are saved by the power electronic (ELP).

If the communication between the power electronic (ELP) and the control
electronic (EW) is defective, the EW sends the message independently that a
fault has occurred.
