Description
The setpoints page 4 header. In this page, switch and relay characteristics
are set up to suit the particular application. These switch inputs are
provided on the 565 Relay back panel to accept external signals for
customer use. The use of switches 1 to 8 is user definable. External
switches can have either normally open (N.O) or normally closed (N.C)
contacts. A normally open switch will have its contacts in the open (non-
conducting) state under inactive conditions. Similarly, a normally closed
switch will have its contacts closed (conducting) in the inactive state. This
information must be given to the 565 Relay if it is to use these inputs. Other
features such as the time and date are also setup on this page.
The current time must be entered here in the following format:
Hour:Minute:Second
For example if the time is 33 minutes and 10 seconds past one in the
afternoon, it would be entered as:
13:33:10
This time setting will not be lost if power supply to the 565 Relay is
interrupted, because a lithium battery maintains the real time clock.
The current date must be entered in this message. The Relay will use this
to keep a record of when trips occurred. The date setting is laid out in the
following form:
Month:Day:Year
For example, if the date is the 4th of August 1992 then the following data
would be entered:
08:04:92
This message allows the user to assign an external switch to the reset
lockout function. This function assignment means that when the appropri-
DISABLED
ate switch is active, it will stop a reset from occurring. This function can be
used to provide an "interlock". For example, it could be used to prevent a
breaker closure after a trip without permission from a remote source.
Select the intended switch for the function, using the NEXT CHOICE key.
The switch choices are:
1) DISABLED
2) SW.1
3) SW.2
4) SW.3
5) SW.4
The complete list of function/switch setpoints is shown as follows:
This setpoint will stop an instantaneous trip from occurring when the
switch is active.
DISABLED
If a switch is assigned this function it will stop all timed overcurrent trips
when the switch is active.
DISABLED
6) SW.5
7) SW.6
8) SW.7
9) SW.8
