b) TIME BETWEEN STARTS TIMER
This timer corresponds to the TIME BETWEEN STARTS TIME DELAY feature in Setpoints page 5, line 24. The time
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 TIME BETWEEN STARTS TIME DELAY feature is set to OFF in Setpoints page 5, line 24.
c) CAUSE OF LAST TRIP
The message in Actual Values page 5, line 3 describes the cause of the last trip. It will be updated when a trip
occurs. XXXXXXXXXXX in the message represents one of the following trips:
d) CAUSE OF LAST EVENT
An event is defined as a TRIP or an INHIBIT. If the last event was a trip, then the message CAUSE OF LAST
EVENT and the following message CAUSE OF LAST TRIP are the same, mainly displaying the cause of the trip.
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 INHIBIT LOCKOUT is displayed as the CAUSE OF LAST EVENT message and the cause
of the trip is displayed as the CAUSE OF LAST TRIP message. Sometimes only an inhibit activates the TRIP,
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 INHIBIT LOCKOUT .
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 SPARE INPUT TO READ 52B? on Setpoints page 5 be changed to YES.
