What causes Haas alarm 214?

SRAM battery on MOCON board is weak or depleted, causing memory directory corruption during power cycles. Program transfer was interrupted via RS-232 or USB causing incomplete write to program memory. MOCON board SRAM chip is failing or has developed bad memory sectors. Power surge or sudden power loss during program save or delete operation corrupted the program directory table. Background memory management process was interrupted during automatic memory defragmentation or optimization.

How do I fix Haas alarm 214?

1. Step 1: Press RESET to clear the alarm and check if program directory displays correctly in the control 2. Step 2: Check SRAM battery voltage at the MOCON board - should read 3.0V or higher, replace if below 2.8V 3. Step 3: Run a program directory check by pressing LIST PROG and verify the count matches what you expect to be in memory 4. Step 4: Perform a soft memory reset using Setting 31 and Setting 33 backup/restore to rebuild the program directory 5. Step 5: If alarm persists, perform full memory clear and reload all programs from backup source to rebuild directory structure 6. Step 6: If alarm continues after memory clear and battery replacement, replace the MOCON board as SRAM chip has likely failed

Alarm 214

Haas 214 - NO. OF PROGRAMS CHANGED | Haas CNC Alarm

This alarm indicates the control has detected a mismatch in the number of programs stored in memory compared to what the system expected during startup or memory integrity check. The MOCON board maintains a directory count of stored programs, and when this count does not match the actual programs found during scan, this alarm triggers. This is typically a sign of memory corruption, incomplete file transfer, or SRAM battery failure on the MOCON board.
