Timer Accuracy
Standard (TD[n]):
+4 and -1 milliseconds ±0.01% of setting
Reclosing (TD79[n]):
+20 and -1 milliseconds ±0.01% of setting
Real Time Clock Set Ability

Real Time Clock Accuracy
Relays with IRIG, ±1 millisecond. If IRIG signal is lost, accuracy defaults to the real time clock stability.
BESTlogic Operate Time
Operate time is 1.4 milliseconds typical, 2.8 milliseconds maximum at 60 hertz.
Output Relays
Any output contact closed by the relay logic will be held closed for 200 to 250 milliseconds even if the
initial cause of the closing goes away. After 200 to 250 milliseconds, the relay close time is determined by
the state of the relay logic. This minimum hold time may be disabled by using the PHOLD command.
Factory Presets
ALARM Output:
Output contacts close when ALARM logic (LOA) is true or power is lost.
Outputs 1 - 5:
Output contacts close when the corresponding logic equation (LO1 -
LO5) is true.
