20 Switch On

Switch On

Caution Before switching on the device, make sure it is set to the voltage of the power supply.

The device is ready for operation on switching it on, if it has been configured and parame- terized at the factory. The green LED „1“ lights up.

The program TZAKON2 and a connection cable for the RS-232C interface are required for configuration and parameter definition by the user (see Configuration Instructions 42/18-51 EN).

Display and control elements (Fig. 16-1) LED „1“ (green) Pilot lamp (power supply) LED „2“ (red) Fault indicator (hardware and software) LED „32 (yellow) Status indicator (program inactive)

The 16-digit LC Display is used for alphanumeric display of the design data as well as for the current measured and calculation values.

The „MOD“ and „STEP“ keys are used for changing the display as well as for selecting the measured variables, device data and parameter data (Fig. 20-1).

With <MOD>, jump from any submenu to the next main menu item.

For „Change time/date“ the digit modifiable with <S> flashes; With <M>, jump to the left to the next higher position.

Note:

The submenu items featured in the main menus „Fault display“, „Electrical measured varia- bles“, „Physical measured variables“ and „Parameter data“ are a function of the computation program selected.
