"Output": Initiates transfer of data over the digital interface (Talk Only

mode). Single parameters, whole test set-ups or dynamic data can be

transferred. During data transfer the "Output" LED will light. When the

output of data has finished, the Talk Only mode will be reset and the

"Output" LED will extinguish. Transfer of Talk Only data can be inter-

rupted by pressing the "Output" key for a second time. If the key is

pressed for a third time a new output is initiated.

"Input": Puts the generator into Listen Only mode for input of test

parameter data over the digital interface. During input of data the "In-

put" LED will light. The Listen Only mode can be interrupted by press-

ing the key for a second time.

"SRQ/Addr.": Requests service from a controller. This function must

first be enabled by the controller. Otherwise, when the key is pressed

the IEEE bus address is displayed for about two seconds.

"Remote": An LED which will light when the generator is remotely con-

trolled via the digital interface. Local control may be regained by

pressing one of the parameter selection keys, providing the Local

Lock Out is not active.

Refer to section 4.2 and chapter 5 for further information about the

use of the Digital Interface.

Power On/Off:

Mains Voltage:

Mains switch for applying the mains supply to the instrument.

Mains voltage selector (which also contains a slow-blow fuse) for oper-

ation of the Vibration Exciter Control from a 100, 115, 127, 200, 220 or

240 V ( ± 20%) single-phase mains supply (50-60Hz). To select the ap-

propriate voltage and to fit the correct fuse, refer to section 3.1.3.
