Application manual
•
989G_OP = 1
•
989G_CL = 0
If, in this case, line voltage supervision is added, then rather than setting 989 to open state,
specify the state of the voltage supervision:
•
989_OP = VOLT_OFF
•
989_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
•
VOLT_OFF = 1
•
VOLT_ON = 0
