NOTE! During any local man-machine communication over the push buttons and the display on the front panel a five minute time-outfunction is active. Thus, if no push button has
been pressed during the last five minutes, the
relay returns to its normal state automatically.
This means that the display turns dark, the relay
escapes from a display mode, a programming
routine or any routine going on, when the relay
is left untouched. This is a convenient way out
of any situation when the user does not know
what to do.
Before a relay module is inserted into the relay
case, one must assure that the module has been
given the correct settings. If there however is
any doubt about the settings of the module to be
inserted, the setting values should be read using
a spare relay unit or with the relay trip circuits
disconnected. If this cannot be done the relay
can be sett into a non-tripping mode by pressing
the PROGRAM push button and powering up
the relay module simultaneously. The display
will show three dashes "- - -" to indicate the nontripping mode. The serial communication is
operative and all main and submenues are accessible. In the non-tripping mode unnecessary
trippings are avoided and the settings can be
checked. The normal protection relay mode is
entered automatically after a timeout of five
minutes or ten seconds after the dark display
position of the main menu has been entered.
