5.2 PRODUCT SETUP
Pushbutton states can be logged by the event recorder and displayed as target messages. In latched mode, user-defined
messages can also be associated with each pushbutton and displayed when the pushbutton is on or changing to off.
• PUSHBUTTON 1 FUNCTION: This setting selects the characteristic of the pushbutton. If set to "Disabled", the push-
button is not active and the corresponding FlexLogic™ operands (both "On" and "Off") are de-asserted. If set to "Self-
Reset", the control logic is activated by the pulse (longer than 100 ms) issued when the pushbutton is being physically
pressed or virtually pressed via a FlexLogic™ operand assigned to the
5 When in "Self-Reset" mode and activated locally, the pushbutton control logic asserts the "On" corresponding Flex-
Logic™ operand as long as the pushbutton is being physically pressed, and after being released the deactivation of
the operand is delayed by the drop out timer. The "Off" operand is asserted when the pushbutton element is deacti-
vated. If the pushbutton is activated remotely, the control logic of the pushbutton asserts the corresponding "On" Flex-
Logic™ operand only for the time period specified by the
If set to "Latched", the control logic alternates the state of the corresponding FlexLogic™ operand between "On" and
"Off" on each button press or by virtually activating the pushbutton (assigning set and reset operands). When in the
"Latched" mode, the states of the FlexLogic™ operands are stored in a non-volatile memory. Should the power supply
be lost, the correct state of the pushbutton is retained upon subsequent power up of the relay.
• PUSHBTN 1 ID TEXT: This setting specifies the top 20-character line of the user-programmable message and is
intended to provide ID information of the pushbutton. Refer to the User-Definable Displays section for instructions on
how to enter alphanumeric characters from the keypad.
• PUSHBTN 1 ON TEXT: This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is in the "on" position. Refer to the User-Definable Displays section for instructions on
entering alphanumeric characters from the keypad.
• PUSHBTN 1 OFF TEXT: This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is activated from the on to the off position and the
"Latched". This message is not displayed when the
status is implied to be "Off" upon its release. The length of the "Off" message is configured with the

applicable only if the pushbutton is in the "Latched" mode.

the latched mode.

button active status after the pushbutton has been released. This setting is required to set the duration of the pushbut-
ton operating pulse.
