5.25 Control panel lock
It is possible to lock the buttons on the control panel
to prevent malfunction of the pump. The locking
function can be set to "ON" or "OFF". The default
setting is "OFF".
A PIN code must be entered to change from "OFF" to
"ON". When "ON" is selected for the first time, "0000"
will appear in the display. If a code has already been
entered, it will appear when an attempt to change to
"ON" is made. This code can either be re-entered or
changed.
If no code has been entered, a code must be set in
the same way as the "NX" and "IN" values described
in section Timer.
If a code has already been entered, active digits are
flashing.
If attempts are made to operate the pump in locked
condition, "LOCKED" will appear in the display for 2
seconds, followed by "0000". A code must be
entered. If the entering of a code has not been started
within 10 seconds, the operating display without
changes will appear.
If a wrong code is entered, "LOCKED" will appear in
the display for 2 seconds, followed by "0000". A new
code must be entered. If the entering of a code has
not been started within 10 seconds, the operating
display without changes will appear. This display will
also appear if the entering of the correct code
exceeds 2 minutes.
If the locking function has been activated but the
control panel is unlocked, the control panel will be
locked automatically if it is not operated for 2 minutes.
The locking function can also be reactivated by
selecting "ON" in the "LOCK" menu. The previously
entered code will then appear and must be re-entered
by pressing the
button four times. The code can
also be changed.
The control panel can be unlocked either by means of
the selected code or the factory code 2583.
