ACTUAL VALUES MODE
b) TIME BETWEEN STARTS TIMER
This timer corresponds to the
displayed is the actual lockout time that the user has to wait before an additional start can be performed.
This timer is updated continuously until it expires, then a zero is displayed. When the timer expires, this indi-
cates to the user that a start is allowed immediately after a motor stop without any lockout time.
The time between starts timer is equal to zero in the following two cases:
1. If the timer has expired and therefore there's no lockout time prior to starting again after a motor stop con-
dition is detected.
2. If the

However, it is possible to have a trip which is immediately followed by an inhibit such as starts/hour or time
between starts,. In this case
of the trip is displayed as the
AUX1, or TRIP and AUX1 relays. This may happen when the motor is intentionally stopped, but more often, it
happens accidentally on an unloaded motor when current drops below 5% of CT. 5% of CT is the cutoff point
for the 269Plus, where a motor stop condition is registered. In this case, the cause of the last trip is not
updated. Only the cause of last event message is updated to show
This message should greatly assist in the diagnosis of the problem, because the activation of the TRIP relay
will not be misunderstood and treated as an actual trip. Instead, the solution may be fairly simple to implement,
and it may only require that a 52b contact for a breaker, or equivalent for a contactor, be wired to terminals 44
and 45 on the 269Plus, and the setpoint
