6.2 OUTPUT ENABLE Button

The circular Output Enable (On/Off) button is located on the right hand side of the front
panel keypad. Its unique circular shape makes is easy to find so the output can be turned off
quickly if needed.
6.2.1

OUTPUT State Indication

The state of the output is indicated by the back light color of the Output On/Off button. A
blue color indicates the output is OFF, a green color indicates the output is ON.
6.2.2

Energy Savings Modes

The AFX Series® was designed to conserve energy when powered on but not in actual use to
power a load. This situation is common as adjustments are being made to the setup or the
load before any power is applied. This mode is controlled by the state of the Output. If the
output is off, the AFX will enter one of two energy savings modes:
1. SLEEP MODE
internal heatsink is sufficiently cool, all fans are turned off as well. This essentially
means the power source draws almost no power at all yet the front panel controls,
displays and all digital control interfaces remain operational so any required
program changes can be made.
2. STANDBY MODE
phase is turned off. This means the first two stages remain on while the output is
off. This means the fan will run at its lowest speed setting for quieter operation. This
mode is considered a fast startup mode.
The desired energy savings mode can be selected from the front panel or via one of the
remote control interfaces using the OUTP:FAST command (See section 8.7.1.).
6.2.3

Output On Response Times

Turning the output ON means that any power stage that was disabled for energy
conservation purposes will be started and allowed to settle. This includes the output
inverters. Once all power stages are up and running, the output relays are closed and
whatever programmed output mode, voltage and frequency (if not in DC mode) will be
applied to the load. If all stages were off – power source in sleep mode – this process can
take up to 2.2 seconds. If the output control mode is set to FAST mode however, only the
inverters are ever turned off and output can be applied within 200 msec, which is typical for
older design power source with no energy saving features or sleep mode capability.
