14 Identification / resetting of defective steps
If the controller has identified a step as defective (3 consecutive switching cycles without mains
reaction) and b
locked this (step type = “
Flty
”), this step is blocked for the control for 24 hours.
D
efective steps are only locked, if the function “Lock faulty steps” is activated (SETUP/309 =
YES).
After this blocking time, the controller resets the step type of this step to
“
AUTO
” and tests this
step again, if necessary. If again no mains reaction is identified to 3 consecutive switching cycles, this
step is locked by the control again for 24 hours (step type = “
Flty
”).
Locked faulty steps are displayed with the step type "
Flty
" in the menu "
INFO
". The respective step
symbol of the step is flashing in the step display.
If the defective step was changed resp. the defective fuse was replaced, the step type can be
switched manually
back to “
AUTO
” (SETUP/100/OUt or SETUP/403). Then, the step is available to
the control for switching again resp. may be switched again in manual operation.
If a defective power contactor was responsible for the identification of the faulty step, the switching
cycle counter of this step (SETUP/404) should be reset manually to 0 after changing the contactor in
order to restart the switching cycle monitoring for the contactor.
15 Adding additional steps
If an existing system is extended by one or several steps, the additional steps may be added in the
step database.
For this purpose, the step type of the additionally occupied switching outputs must be set to “
AUTO
”
(SETUP/100/OUt or SETUP/403).
If the step identification is switched off (SETUP/308 =
NO
), the step sizes for these steps must also be
entered manually (SETUP/402).
