System Operation Monitor (LSOM)

The system operation monitor (A132) detects the most common fault conditions in the air conditioning system. When an abnormal condition is detected, the module com- municates the specific condition through its ALERT and TRIP lights. The module is capable of detecting both me- chanical and electrical system problems. See figure 9 for the system operation monitor.

LSOM LED Functions

Power LED (green) −− Voltage within the range of 19−28VAC is present at the system monitor power connec- tion.

Alert LED (yellow) −− Communicates an abnormal system condition through a unique flash code. The alert LED flashes a number of times consecutively; then pauses; then repeats the process. This consecutive flashing corre- sponds with a particular abnormal condition.

Trip LED (red) −− Indicates a demand signal from the ther- mostat; but detects no current to the compressor.

Flash code number −− Corresponds to a number of LED flashes, followed by a pause, and then repeated.

Trip & Alert LEDs flashing simultaneously −− Indicates that the control circuit voltage is too low for operation.

Reset ALERT flash code by removing 24VAC power from monitor. Last ALERT flash code will display for 1 minute af- ter monitor is powered on.

LSOM codes are given in table 5.
