CHAPTER 5: SETPOINTS 5.5 CONTROL ELEMENTS
GEK-106310-AF F650 DIGITAL BAY CONTROLLER 5-127
The block signals for the frequency rate of change element can be viewed at: Actual > Status > Protection > Protection
Blocks:
Maximum number of starts actual values description:
Number of starts operate: Reading state. This state is activated when maximum number of starts has been reached
within one hour or when the time to restart setting has been programmed.
Global Starts Counter: Reading state. Provides the number of starts of the motor detected by the unit. This value can be
reset by means of “Reset counter” setting. This counter is increased when the motor goes from motor stopped to motor
started. When the “NUMBER OF STARTS OP” is activated indicating a excessive number of starts, changes in the breaker or
average current above 7% do not increase this counter.
Starts Hour Block Lockout Time: Reading state. If the unit is enabled, this state shows the lockout time in minutes until a
new start of the motor is enabled by this element. If maximum number of starts are below “Number of starts” setting, this
state shows 0 min indicating that there is not lockout time.
Block number of starts: Writing state. When this state is set the unit is blocked, meaning that the Lockout time and the
number of starts counted within last hour are reset to a zero value allowing starting operations in the motor. The “Number
of starts counter” continues with the last value and does not reset because of blocking the unit.
Note: All the counters are stored in a RAM memory, therefore when the relay is powered off and powered, on all timers and
counters are set to a zero value.
5.5.9 Digital counters
Digital Counters are functions to count discrete bit logic value changes, for example, it is able to count the number of
pickups of a protection element, the number of breaker openings or the contact inputs state changes.
There are 8 identical digital counters and they count the number of state transitions from Logic 0 to Logic 1, of the logic
states configured by the user, that trigger the increment or decrement commands of the digital counter value.
Settings
For each of the 8 digital counters, there exist independent and identical groups of settings:
MAXIMUM NUMBER OF STARTS STATUS
NUMBER OF STARTS OP
GLOBAL STARTS CNT
BLOCK LOCKOUT TIME
MAXIMUM NUMBER OF STARTS BLOCKS
BLOCK NUM OF STARTS
