Synergy Nano Low Program Memory & Low Storage Alarms
There are 2 types of local storage on the Synergy Nano: Storage Card (Flash) and RAM. The Storage Card
holds all the application programs, user chamber programs and log files. RAM is used exclusively by the
operation system and Synergy Nano software. The Synergy Nano monitors both storage areas for low
memory.
Low Program Memory Alarm
In the event that the RAM memory runs low, the Synergy Nano operating system will no longer run
efficiently. If a Low Program Memory condition exists a pop up window warns "The Synergy Nano 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 Nano to clear this error.
Note: Synergy Nano applications before version 2.0.0 had an issue that caused Low Program Memory
Alarms. This issue was fixed in 2.0.0 and later versions. Contact Tidal Engineering for upgrade information if
your controller software version is earlier than 2.0.0.
Low Storage Alarm
The Synergy Nano 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 Nano 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 then 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.
