programming.
Digital LED Operator Alarm Display
The LED digital operator can display an alarm to warn of approaching maintenance
periods.
Table 6.5 Maintenance Alarm Programming
NOTICE: After replacing parts, reset the appropriate maintenance parameters (o4-03, o4-05,
o4-07, and o4-09) to 0. If these parameters are not reset, the function will continue to count
down the performance life of the new replaced components.
