5725A Operating Functions and Modes

3-6. 5725A Operating Functions and Modes

Warning

Both the 5700A and 5725A can produce fatal voltages. boosted voltage operation produces high voltage at higher current levels than normally available from the 5700A. during 5725A voltage operation, the potential risk of injury or fatal accident is greater than during unamplified 5700A voltage operation.

The 5725A has five normal modes of operation, including active output in its three output functions: ac voltage, dc current, and ac current. The five normal operating modes are:

Standby (also referred to as "dormant" on the schematics)

Voltage Standby

Current Standby

Voltage Operate

Current Operate

Each normal operating mode is described in the following paragraphs. For the meaning of FAULT, OVERLOAD, or CABLE OFF indications, refer to Table 3-1.

Figure 3-3. Standby Mode Indicator

Standby mode is when only the 5725A STANDBY indicator is lit. In standby mode, the 5725A is not supplying an output. However, the 5700A, depending on how it is set, can be supplying up to 1100V or 2.2A. Standby occurs under any of the following conditions:

At power-up with no pending 5725A entry on the 5700A.

When the 5725A is not selected in a 5700A setup menu as the amplifier for the 5700A output function in use, and the 5725A is not selected as the output location for all 5700A current.
