File Name Limitations
There is a limit of 999 file names with the same first four characters. Internal file names are
restricted by the DOS 8-character-dot-3-character limit. Therefore trend log files are identified
internally by the first four characters of the object name plus tilde plus a three digit number.
Examples are:
TREND GRAPH EAST CHILLER TEMP_130925.txt is saved internally as TREN~001.txt
TREND GRAPH WEST CHILLER TEMP_130925.txt is saved internally as TREN~002.txt
As new log files are created in each 24 hour period, these files count against the maximum of
999 files. If multiple graph objects appear on one screen, the files will be identified internally
by the first Two Characters of the screen name plus the first Two Characters of the object
name plus tilde plus three digit number.
To maximize storage capabilities on external memory devices use screen names that have
unique characters in the first four digits and object names that are unique in the first two
characters.
NOTE: When the 999 filename limit is reached, the oldest files will automatically be deleted and logging will
continue.
Power Loss Retention
When a power loss is detected, the panel will attempt to complete all data logging operations
safely.
The power retention while using a DC power is not long enough to complete writes to an SD
Card or USB device. An Uninterruptable Power Supply (UPS) should be considered.
Power Loss Detection (at 25°C)
Power Supply Detect Loss
DC (Panel only) 8.9 VDC
EA-AC
67VAC (6 - 10 inch)
70VAC (12 - 15 inch)
Chemical Compatibility
The C-more touch panels comprise three different materials that may be exposed to outside
elements: a gasket, a screen sheet and a bezel.
• Gasket material is silicone.
• Screen sheets are PET.
• Panel bezels are ABS plastic.
