1 Alarms can be cleared by using the alarm clear. Because the all existing alarms are kept cleared while the alarm
clear input (A-CLR) is kept ON, be sure to turn it OFF during normal operation. Either 1 s to 10 s or ∞ can be
selected by using user parameter.
Exception: Battery alarm is fixed at ∞ because it is latched by the encoder.
Because the end of life alarm means that the life expectancy cannot be extended, the alarm is set at ∞.
