The latching output contacts are mechanically bi-stable and controlled by two separate (open and close) coils. As such they
retain their position even if the relay is not powered up. The relay recognizes all latching output contact cards and populates
the setting menu accordingly. On power up, the relay reads positions of the latching contacts from the hardware before exe-
cuting any other functions of the relay (such as protection and control features or FlexLogic).
The latching output modules, either as a part of the relay or as individual modules, are shipped from the factory with all
latching contacts opened. It is highly recommended to double-check the programming and positions of the latching con-
tacts when replacing a module.
Since the relay asserts the output contact and reads back its position, it is possible to incorporate self-monitoring capabili-
ties for the latching outputs. If any latching outputs exhibits a discrepancy, the
LATCHING OUTPUT ERROR
self-test error is
declared. The error is signaled by the
LATCHING OUT ERROR
FlexLogic operand, event, and target message.
•
OUTPUT H1a OPERATE
: This setting specifies a FlexLogic operand to operate the ‘close coil’ of the contact. The
relay will seal-in this input to safely close the contact. Once the contact is closed and the
RESET
input is logic 0 (off),
any activity of the
OPERATE
input, such as subsequent chattering, will not have any effect. With both the
OPERATE
and
RESET
inputs active (logic 1), the response of the latching contact is specified by the
OUTPUT H1A TYPE
setting.
•
OUTPUT H1a RESET
: This setting specifies a FlexLogic operand to operate the ‘trip coil’ of the contact. The relay will
seal-in this input to safely open the contact. Once the contact is opened and the
OPERATE
input is logic 0 (off), any
activity of the
RESET
input, such as subsequent chattering, will not have any effect. With both the
OPERATE
and
RESET
inputs active (logic 1), the response of the latching contact is specified by the
OUTPUT H1A TYPE
setting.
•
OUTPUT H1a TYPE
: This setting specifies the contact response under conflicting control inputs; that is, when both the
OPERATE
and
RESET
signals are applied. With both control inputs applied simultaneously, the contact will close if set to
“Operate-dominant” and will open if set to “Reset-dominant”.

Application Example 1:
A latching output contact H1a is to be controlled from two user-programmable pushbuttons (buttons number 1 and 2). The
following settings should be applied.
Program the Latching Outputs by making the following changes in the
