Synergy Controller Low Program Memory & Low Storage Alarms
There are two types of local storage on the Synergy Controller: Storage Card (Flash) and RAM. The Storage
Card holds all the application programs, programs, and log files. RAM is used exclusively by the Operating
System (OS) and Synergy Controller software. The Synergy Controller monitors both storage areas for low
memory.
Low Program Memory Alarm
In the event that the RAM memory runs low, the Synergy Controller operating system will no longer run
efficiently. If a Low Program Memory condition exists a pop up window warns "The Synergy Controller is
running low on memory. Please reboot at your earliest convenience" and the Maintenance Alarm screen will
display the message "Low Program Memory". Reboot the Synergy Controller to clear this error.
Low Storage Alarm
The Synergy Controller monitors the space remaining on the Storage Card Flash memory device, and
generates an alarm condition when the space remaining is less than 160K. When this occurs, you can clear
the log file, export screenshots or remove programs from the Storage Card to free up Storage Memory to
correct this condition.
A Low Storage Alarm can occur when the log file has grown too large. When your chamber is properly setup
the Synergy Controller will log until the file gets to a specified maximum size and then begin overwriting the
oldest records, thus limiting it to the specified size. The maximum size specified for the log file should be
less than the physical space available. Step-by-step instructions for clearing the alarm and adjusting the
chamber settings to prevent this alarm from reoccurring are illustrated below.
Removing a Low Storage Alarm Condition
Synergy Controller Technical Manual, Revision H
When an alarm occurs, the word "ALARM" flashes
in the title bar of the Synergy Controller screen. To
determine if your alarm condition is a Low Storage
alarm, go to the Maintenance\Alarms folder and
read the alarm description.
To clear the alarm condition, export the logging
history data and clear the file according to the
following steps:
Go to Setup Screen folder and scroll down to select
the Logging folder.
