Controls and Indicators
Figure 2--1 shows the layout of the ECO422D front-panel controls and indica-
tors.
Figure 2- 1: Front-panel controls
Sync Source - Primary/Backup.
The LED indicates the current Output (whether it
is from the Primary or Backup input). It can be manually changed using the Sync
Source button. (If the ECO422D is in Normal mode, this is only true when the
other input is good or both inputs are bad. Refer to
User Configuration Switch
(S14--8)
on page 2--4.) Only one of these LEDs can be on. Primary is the default
at power-up.
Auto Switching - Switch on Fault/Disabled.
This selects whether the ECO422D
will automatically switch to the other input source whenever it detects a fault
(Switch on Fault) or not switch (Disabled). Only one of these LEDs can be on
after the power-up delay. Switch on Fault is the default setting. During power-up,
the DISABLED LED slowly blinks to indicate disabled front panel and error
detection during the power--up delay.
Fault Indicator (Reset) - Primary/Backup.
Either one or both of these LEDs could
be on. They indicate that a fault has occurred on the input. Press the Reset button
to clear the fault indicators (turn off the LEDs) after the fault has been corrected.
The fault indicator does not automatically reset after an error condition improves.
At power-up, the LEDs are reset.
Front Panel - Enabled/Locked Out.
This control determines whether or not the
operator has access to the other front-panel controls. If it is Enabled, then the
user can control the instrument from the front panel. If it is Locked Out, then the
user can only toggle back to Enabled and no other front-panel controls are
available. The ECO422D will automatically lock out after about 1 minute of
inactivity to prevent accidental switching. The front panel is automatically
locked out at power-up (during power up, both LEDs are lit).
