4.11 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,
"_ _ _ _" 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.
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 "_ _ _ _". A code must be
entered. If the entering of a code has not been
started within 10 seconds, the operating display with-
out changes will appear.
