5. Programming (Set)
In order to permit the widest possible use
of the control relay, multiple settings are
available. To simplify matters, the control
relay is set to standard values in our
factory before delivery.
(see Table 1, pages 15 to 17)
The user only needs to change the target
power factor or a few values to suit his
special requirements. As a protection
against unintentional reprogramming, the
set mode (programming mode) can be
invoked only within 5 minutes after operat-
ing voltage is applied. After this period the
values can only be read (read-only mode).
If the set mode has been activated within
these 5 minutes, it remains available for
one hour. In order to reach the set mode
again after this period, it is necessary to
disconnect the control relay from its sour-
ce for a short period of time.
The procedure for checking or repro-
gramming the set values is as follows:
• Press the "man/set" button for at least
eight seconds to switch to the set mode.
The display then shows "-01-". This
number corresponds to the first variable
which is displayed or can be changed in
the following sequence (see Table 1).
• The actual value appears on the display
when the "man/set" is pressed again.
• By pressing the "+" or "-" button the next
higher or lower setting can be attained.
The control relay is in the read-only
mode if above is not possible. To reach
the set mode again, the control relay
must be disconnected from its source
for a short period of time.
• Press the "man/set" button repeatedly;
the mode numbers appear followed by
the programmed value (see Table 1).
• If the "+" is pressed again after mode
number "-24-" appears on the display, or
if the "-" is pressed again after mode
number "-01-" appears on the display,
then the display will show "End".
• By confirming the display "End" by
pressing the "man/Set" button the con-
trol relay assumes normal operation; the
preset values are then permanently
stored in a non-volatile memory.
Notice:
During the "set mode" none of the
capacitor stages is changed and there is
no switching of the alarm contact.
