Operating Basics
Configure the startup delay
The Startup Del
ay function defines the time period after the ECO8000 Series
unit powers up, during which the instrument will not make AUTO mode source
switches. The Channel Control system (left-hand buttons) and the basic ECO
functions are fully operational a second or two after power is applied. However,
on loss of power the sync sources may not be ready for a period of time depending
on the type of sync pulse generator. While the sync pulse generator is starting
up, the ECO m
ay make undesirable source switche s as the sync pulse generator
signals turn on at different times.
To prevent
this, the ECO8000 Series has the ability to delay AUTO mode
switching for the period of time set in the Startup Delay function. Additionally, at
the end of the start up delay, any yellow LED states are cleared (this is effectively
like asserting the Fault Reset button at the end of the timeout period).
Set the startup delay. Perform the following steps to set the startup delay:
1. Cycle the power on the sync pulse generators connected to the ECO8000
Series and measure the amount time until the sync generators are fully booted
and the
LEDS on the ECO h ave all turned to yellow.
CAUTION. IfthesyncgeneratorsareconfiguredtouseGPSasthetimingsource
and if you have the SPG trigger function configuredtomonitortheGPSlock,
you need to include the time necessary for the sync generators to lock to the
GPS signal.
2. Add a few seconds to the measured startup time of the sync pulse generators
to provide some margin. For example, if the startup time of the sync pulse
generators is 30 seconds, then a good value for the ECO startup delay would
be
35 seconds.
3. On the ECO8000 Series, access the SYSTEM CONFIG menu.
4. Press the up (▲)anddown(▼) arrow buttons to select STARTUP DELAY.
5. Press the left (◄)orright(►) arrow button to set the startup delay time
period.
NOTE. You can also use the System tab in the Web Interface to set the startup
delay.
