SAMPLE CONCENTRATION ALARMS
When the 9031CX Sodium system is in normal operation mode one alarm operates as a “low”
alarm and the other operates as a “high” alarm. The CONC LOW alarm is activated when the
sodium level decreases below the set value. The CONC HIGH alarm is activated when the
sodium level increases above the set value. The two sodium alarms control the relays
provided. Each relay has one pair of changeover contacts rated at 2A, 250VAC (non-
inductive). S ee F igure 10 f or location of alar m r elays
