CHAPTER 5: SETTINGS
The selector switch element is intended to replace a mechanical selector switch. Typical applications include setting group
control or control of multiple logic sub-circuits in user-programmable logic.
The element provides for two control inputs. The step-up control allows stepping through selector position one step at a
time with each pulse of the control input, such as a user-programmable pushbutton. The three-bit control input allows
setting the selector to the position defined by a three-bit word.
The element allows pre-selecting a new position without applying it. The pre-selected position gets applied either after
time-out or upon acknowledgement via separate inputs (user setting). The selector position is stored in non-volatile
memory. Upon power-up, either the previous position is restored or the relay synchronizes to the current three-bit word
(user setting). Basic alarm functionality alerts the user under abnormal conditions; for example, the three-bit control input
being out of range.
A selector switch runs every two power cycles.
— This setting defines the upper position of the selector. When stepping up through available
SELECTOR 1 FULL RANGE
positions of the selector, the upper position wraps up to the lower position (position 1). When using a direct three-bit control
word for programming the selector to a desired position, the change would take place only if the control word is within the
range of 1 to the
SELECTOR FULL RANGE
FlexLogic operand for three seconds.
SELECTOR ALARM
— This setting defines the time-out period for the selector. This value is used by the relay in the
SELECTOR 1 TIME-OUT
following two ways. When the
of the control input after which the pre-selected position is automatically applied. When the
"Acknowledge," the setting specifies the period of time for the acknowledging input to appear. The timer is re-started by
any activity of the control input. The acknowledging input must come before the
otherwise, the change does not take place and an alarm is set.
