Reactive Factor Controller CX plus

MANUAL (manual operation: Manually switch steps on and off)
It is possible to manually switch the step outputs of the CX plus for test purposes. The automatic
control
is stopped in the “MANUAL” menu. In order to prevent an unintentional stopping of the control,
this menu item is provided with a key lock (keep the key "
" pressed for 3 s in order to enter the
MANUAL menu). As soon as you leave the menu, the control restarts automatically and switches off
those steps which are not necessary, as the case may be.
NOTE:
The discharge time lock is observed when manually switching steps. After manually switching
off a step, the discharge time lock for this step is active. The affected step can only be switched on
again after the discharge time lock.
NOTE:
Deactivated steps (FOFF), steps which are permanently switched on (FON) and locked steps
(FAULTY, FOFF due to step-power-lost-alarm) cannot be switched manually.
NOTE:
A manual operation of the steps is not possible,
when the control algorithms “LIFO”, “FIFO” or
“COMBI-FILTER” are set. The MANUAL menu is locked.
NOTE:
If the step database was switched off by U-ALARM, TEMP2, THD-U or THD-I alarm, it is not
possible to switch the steps manually anymore, while the alarm is still active. When the step database
has been restarted again, the discharge time lock for all steps runs out first. The MANUAL menu is
locked if the automatic initialisation was activated in the SETUP/100/Ai or SETUP/207 resp. for as
long as the setting is activated (AI has not been started yet) or for as long as the AI is executed (
is
shown in the top line on the display in the main menu). It is not possible to switch the steps manually.
