SELECTOR SWITCH 1(2)
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 set-
ting 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 set-
ting). Basic alarm functionality alerts the user under abnormal conditions; for example, the three-bit control input being out
of range.
• SELECTOR 1 FULL RANGE : This setting defines the upper position of the selector. When stepping up through avail-
able 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
. If the control word is outside the range, an alarm is established
by setting the
SELECTOR ALARM
FlexLogic operand for 3 seconds.
